310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.01: Introduction and Purpose
(1) Introduction. 310 CMR 10.00 is promulgated by the Commissioner of the Massachusetts
Department of Environmental Protection pursuant to the authority granted under The Wetlands
Protection Act, M.G.L. c. 131, § 40. 310 CMR 10.00 shall complement M.G.L. c. 131, § 40,
and shall have the force of law.
310 CMR 10.01 through 10.10 provide definitions and procedures. 310 CMR 10.01 through
10.10 pertains to both inland and coastal areas subject to protection under M.G.L. c. 131, § 40.
310 CMR 10.21 through 10.60 provide standards for work within those areas. 310 CMR 10.21
through 10.37 pertains only to coastal areas and 310 CMR 10.51 through 10.60 pertains only to
inland areas. A project may be subject to regulation under 310 CMR 10.00 in which case
compliance with all applicable regulations is required.
(2) Purpose. M.G.L. c. 131, § 40 sets forth a public review and decision-making process by
which activities affecting Areas Subject to Protection Under M.G.L. c. 131, § 40 are to beregulated in order to contribute to the following interests:-protection of public and private water supply-protection of ground water supply-flood control-storm damage prevention
-prevention of pollution-protection of land containing shellfish
-protection of fisheries
-protection of wildlife habitat
The purpose of 310 CMR 10.00 is to define and clarify that process by establishing standard
definitions and uniform procedures by which conservation commissions and the Department may
carry out their responsibilities under M.G.L. c. 131, § 40. Applicants and issuing authorities
shall use forms provided by the Department to implement 310 CMR 10.00.
310 CMR 10.00 is intended solely for use in administering M.G.L. c. 131, § 40; nothing
contained herein should be construed as preempting or precluding more stringent protection of
wetlands or other natural resource areas by local by-law, ordinance or regulation.
10.02: Statement of Jurisdiction
(1) Areas Subject to Protection Under M.G.L. c. 131, § 40. The following areas are subject to
protection under M.G.L. c. 131, § 40:
(a) Any bank,the ocean
any freshwater wetland,any estuary
any coastal wetland,any creek
any beach,bordering any river
any dune, on any stream
any flat,any pond
any marsh,or any lake
or any swamp
(b) Land under any of the water bodies listed above
(c) Land subject to tidal action
(d) Land subject to coastal storm flowage
(e) Land subject to flooding
(f) Riverfront area.
(2) Activities Subject to Regulation Under M.G.L. c. 131, § 40.
(a) Activities Within the Areas Subject to Protection Under M.G.L. c. 131, § 40. Any
activity proposed or undertaken within an area specified in 310 CMR 10.02(1), which will
remove, fill, dredge or alter that area, is subject to Regulation under M.G.L. c. 131, § 40 and
requires the filing of a Notice of Intent except:
1. minor activities within the riverfront area meeting the requirement of 310 CMR
10.02(2)(b)1. or 2.; and
Wetland Regulations – May 2008 Page 2
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.02: continued
2. activities conducted to maintain, repair or replace, but not substantially change or
enlarge an existing and lawfully located structure or facility used in the service of the
public and used to provide electric, gas, water, telephone, telegraph and other
communication services, provided said work utilizes the best practical measures to avoid
or minimize impacts to wetland resource areas outside the footprint of said structure or
facility. A project proponent claiming that work to remove, fill, dredge or alter an area
specified in 310 CMR 10.02(1) does not require the filing of a Notice of Intent has the
burden of establishing that the work is not subject to Regulation under M.G.L. c. 131,
§ 40.
(b) Activities Within the Buffer Zone. Any activity other than minor activities identified
in 310 CMR 10.02(2)(b)1. proposed or undertaken within 100 feet of an area specified in 310CMR 10.02(1)(a) (hereinafter called the Buffer Zone) which, in the judgement of the issuing
authority, will alter an Area Subject to Protection Under M.G.L. c. 131, § 40 is subject toregulation under M.G.L. c. 131, § 40 and requires the filing of a Notice of Intent. [ See also310 CMR 10.05(3)(a)2.] The areas subject to jurisdiction identified in 310 CMR 10.02(1)(b)through (f) do not have a buffer zone.
1. Minor activities within the buffer zone and outside any areas specified in 310 CMR10.02(1)(a) through (e) are not subject to regulation under M.G.L. c. 131, § 40:
a. Unpaved pedestrian walkways for private use;
b. Fencing, provided it will not constitute a barrier to wildlife movement;
stonewalls; stacks of cordwood;
c. Vista pruning, provided the activity is located more than 50 feet from the mean
annual high water line within a riverfront area or from bordering vegetated wetland,
whichever is farther. (Pruning of landscaped areas is not subject to jurisdiction under
310 CMR 10.00.);
d. Plantings of native species of trees, shrubs, or groundcover, but excluding turf
lawns;
e. The conversion of lawn to uses accessory to residential structures such as decks,
sheds, patios, and pools, provided the activity is located more than 50 feet from the
mean annual high-water line within the riverfront area or from bordering vegetated
wetland, whichever is farther, and erosion and sedimentation controls are
implemented during construction. The conversion of such uses accessory to existing
single family houses to lawn is also allowed. (Mowing of lawns is not subject to
jurisdiction under 310 CMR 10.00);
f. The conversion of impervious to vegetated surfaces, provided erosion and
sedimentation controls are implemented during construction; and
g. Activities that are temporary in nature, have negligible impacts, and are necessary
for planning and design purposes (e.g., installation of monitoring wells, exploratory
borings, sediment sampling and surveying).
2. Activities within the buffer zone of any inland resource area as specified in 310 CMR
10.51 through 10.60 and outside any areas specified in 310 CMR 10.02(1) are not subject
to further regulation under M.G.L. c. 131, § 40, provided:
a. The applicant certifies at the time of filing an Abbreviated Notice of Resource
Area Delineation that any work will comply with 310 CMR 10.02(2)(b)2.a. through
j. and, if not, the applicant will file a Notice of Intent or Request for Determination
of Applicability and receive a negative Determination of Applicability or an Order
of Conditions prior to any work;
b. The boundary of any resource area specified in 310 CMR 10.02(1) adjacent to the
project site is confirmed through an Order of Resource Area Delineation. The Order
shall also confirm that the requirements of 310 CMR 10.02(2)(b)2.c., d., and e., are
met;
c. The buffer zone does not contain slopes greater than 15% prior to any work;
d. The buffer zone does not contain estimated wildlife habitat which is identified on
the most recent Estimated Habitat Map of State-listed Rare Wetlands Wildlife of the
Natural Heritage and Endangered Species Program;

10.02: continued
f. At a minimum, no work, including any alteration for stormwater management, isproposed in the 50-foot wide area in the buffer zone along any resource area;
g. The amount of impervious surface shall not exceed 40% of the area of the bufferzone between 50 and 100 feet from any resource area or the amount of existing
impervious surface, whichever is greater, no impervious surface or any otheralteration is allowed within the 50 foot area of the buffer zone along the resource
area;h. Erosion and sedimentation controls are installed and maintained at the limit ofwork or at least 50 feet from the resource area, whichever is farther away, sufficient
to prevent sediment from reaching resource areas during construction. The applicantshall provide written notification to the conservation commission one week prior to
commencement of work to allow verification that erosion and sediment controls areproperly installed.
i. Stormwater is managed according to the Stormwater Management Standards asprovided in 310 CMR 10.05(6)(k) through (q), and the conservation commissionconcurs. The Stormwater Management Plans shall also show that the requirements
of 310 CMR 10.02(2)(b)2.f., g., and h. have been met and the conservationcommission concurs. The applicant shall identify the type of project on the
Abbreviated Notice of Resource Area Delineation to allow the conservationcommission to verify the applicability of the Stormwater Management Standards as
provided in 310 CMR 10.05(6)(k) through (q). If the conservation commission doesnot concur, it shall specify which of the Stormwater Management Standards or other
requirements are not met, and the applicant shall file a Notice of Intent. Anystormwater management structures shall be operated and maintained as a continuingcondition to ensure that the system functions as designed.
j. No Notice of Intent or Request for Determination of Applicability may be filedfor work within the 50-foot wide area in the buffer zone along the resource area
during the three-year term of an Order of Resource Area Delineation, or any extendedOrder, or until the applicant receives a Certificate of Compliance, whichever is later.
Subsequent work within the 50-foot wide area shall be subject to the provisions of310 CMR 10.53(1).
3. Activities within the buffer zone which do not meet the requirements of 310 CMR10.02(2)(b)1. and 2. are subject to preconstruction review through the filing of aDetermination of Applicability to clarify jurisdiction or a Notice of Intent under the
provisions of 310 CMR 10.05(4) and 310 CMR 10.53(1).(c) Notwithstanding the provisions of 310 CMR 10.02(1) and (2)(a) and (b), the
construction, operation, and/or maintenance of a stormwater management system designed,constructed, and installed in accordance with the Stormwater Management Standards as
provided in 310 CMR 10.05(6)(k) through (q) does not by itself create additional AreaSubject to Protection Under M.G.L. c. 131, § 40 or additional Buffer Zone provided that:1. the system was designed, constructed, and installed on or after January 2, 2008; and
2. if the system was constructed in an Area Subject to Protection Under M.G.L. c. 131,§ 40 or Buffer Zone, the system was designed, constructed, and installed in accordance
with all applicable provisions in 310 CMR 10.00.(d) Activities Outside the Areas Subject to Protection Under M.G.L. c. 131, § 40 and the
Buffer Zone. Any activity proposed or undertaken outside the areas specified in 310 CMR10.02(1) and outside the Buffer Zone is not subject to regulation under M.G.L. c. 131, § 40
and does not require the filing of a Notice of Intent unless and until that activity actuallyalters an Area Subject to Protection Under M.G.L. c. 131, § 40.In the event that the issuing authority determines that such activity has in fact altered an
Area Subject to Protection under M.G.L. c. 131, § 40, it may require the filing of a Noticeof Intent and/or issuance of an Enforcement Order and shall impose such conditions on the
activity or any portion thereof as it deems necessary to contribute to the protection of theinterests identified in M.G.L. c. 131, § 40.
(3) Notwithstanding the provisions of 310 CMR 10.02(1) and (2), the maintenance of a
stormwater management system constructed from November 18, 1996 through January 1, 2008,in accordance with the Stormwater Management Standards, as provided in the MassachusettsStormwater Policy, issued by the Department on November 18, 1996 or on or after
January 2, 2008, in accordance with the Stormwater Management Standards as provided in310 CMR 10.05(6)(k) through (q) is not subject to Regulation under M.G.L. c. 131, § 40
provided that:

10.02: continued
(a) if the system was constructed in an Area Subject to Protection Under M.G.L. c. 131,
§ 40 or associated Buffer Zone, the system was constructed in accordance with all applicable
provisions of 310 CMR 10.00;
(b) the work to maintain the stormwater management system is limited to maintenance of
a stormwater management system as defined in 310 CMR 10.04; and
(c) said work utilizes best practical measures to avoid and minimize impacts to wetland
resource area outside the footprint of the stormwater management system.
Notwithstanding the provisions of 310 CMR 10.02(1) and (2), any bordering vegetated
wetland, bank, land under water, land subject to flooding, or riverfront area created solely
for the purpose of stormwater management shall not require the filing of a Notice of Intent
to maintain the stormwater management system, provided that:1. the work to maintain the stormwater management system is limited to the
maintenance of a stormwater management system as defined in 310 CMR 10.04; 2. the stormwater management system was proposed in a Notice of Intent filed beforeJanuary 2, 2008, and conforms to an Order of Conditions issued after April 1, 1983; 3. the area is not altered for other purposes; and4. said work utilizes best practical measures to avoid and minimize impacts to wetlandresource areas outside the footprint of the stormwater management system.
(4) Notwithstanding anything to the contrary in 310 CMR 10.00, work other than maintenance
that may alter or affect a stormwater management system (including work to repair or replace
the stormwater management system, and any change to the site that increases the total or peak
volume of stormwater managed by the system, directs additional stormwater to the system,
and/or increases the volume of stormwater exposed to land uses with higher potential pollutant
loads) that was designed, constructed and installed in an Area Subject to Protection Under
M.G.L. c. 131, § 40 or Buffer Zone, as described in 310 CMR 10.02(1) and (2)(a) through (d),
after January 1, 2008, solely for the purpose of stormwater management,in accordance with the
Stormwater Management Standards as provided in 310 CMR 10.05(6)(k) through (q), may be
permitted through an Order of Conditions, Simplified Review Order of Resource Area
Delineation, or Negative Determination of Applicability provided that the work:
(a) at a minimum provides the same capacity as the original design to attenuate peak
discharge rates, recharge the ground water, and remove total suspended solids;
(b) complies with the Stormwater Management Standards as provided in 310 CMR
10.05(6)(k) through (q); and
(c) meets all the performance standards for any work that takes place in an Area Subject to
Protection Under M.G.L. c. 131, § 40 or Buffer Zone as described in 310 CMR 10.02(1) and
(2)(a) through (d).
(5) For purposes of 310 CMR 10.02(2)(c) and 10.02(4), the applicant has the burden of proving
that the proposed project involves a stormwater management system designed, constructed and
installed in accordance with the Stormwater Management Standards as provided in 310 CMR
10.05(6)(k) through (q) and that the system was designed, constructed and installed on or after
January 2, 2008. The applicant also has the burden of establishing whether said stormwater
management system was installed in an Area Subject to Protection Under M.G.L. c. 131, § 40
or associated Buffer Zone, and, if so, the type of wetland resource area and its size. An applicant
shall use the best evidence available to meet the burden of proof required. For purpose of
310 CMR 10.02(2)(c) and 10.02(4), the best evidence is the Order of Conditions, Order of
Resource Area Delineation or Determination of Applicability for the project served by the
stormwater management system together with the plans referenced in and accompanying such
Order or Determination, and, if applicable, the Certificate of Compliance. If the best evidence
is available, the date the system was designed shall be the date the Notice of Intent, Request for
Determination or Notice of Resource Area Delineation was filed. If the best evidence is not
available, the applicant shall rely on other credible evidence to meet the required burden of proof
such as local approval of the stormwater management system along with the plans referenced in
and accompanying said approval and the wetland conservancy maps and wetland change maps
published by the Department on MassGIS.

Commentary
The Department has determined that activities within Areas Subject to Protection Under
M.G.L. c. 131, § 40 are so likely to result in the removing, filling, dredging or altering of those
areas that preconstruction review is always justified, and that the issuing authority shall therefore
always require the filing of a Notice of Intent for said activities.
The Department has determined that activities within 100 feet of those areas specified in
310 CMR 10.02(1)(a) are sufficiently likely to alter said areas that preconstruction review may
be necessary. Therefore, a request for a Determination of Applicability must be filed for some
activities within the Buffer Zone. The issuing authority shall then make a determination as to
whether the activity so proposed will alter an Area Subject to Protection Under M.G.L. c. 131,
§ 40 and, if so, shall require the filing of a Notice of Intent for said activities. The issuingauthority shall not require the filing of a Notice of Intent if it determines that the activity
proposed within the Buffer Zone will not alter an Area Subject to Protection Under M.G.L.c. 131, § 40. The Department has established simplified review criteria for eligible activitieswithin the buffer zone more than 50 feet from resource areas, based upon a determination thatthe eligibility requirements are sufficient to meet the requirements of 310 CMR 10.53(1) for
protection of resource areas from work in the buffer zone.
Wetland Regulations – May 2008 Page 6
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.02: continued
The Department has determined that activities outside the Areas Subject to Protection Under
M.G.L. c. 131, § 40 and outside the Buffer Zone are so unlikely to result in the altering of Areas
Subject to Protection Under M.G.L. c. 131, § 40 that preconstruction review is not required, and
therefore the issuing authority shall not regulate said activities unless and until they actually
result in the altering of an Area Subject to Protection Under M.G.L. c. 131, § 40.
10.03: General Provisions
(1) Burden of Proof.
(a) Any person who files a Notice of Intent to perform any work within an Area Subject to
Protection Under M.G.L. c. 131, § 40 or within the Buffer Zone has the burden ofdemonstrating to the issuing authority:
1. that the area is not significant to the protection of any of the interests identified inM.G.L. c. 131, § 40; or 2. that the proposed work within a resource area will contribute to the protection of theinterests identified in M.G.L. c. 131, § 40 by complying with the general performancestandards established by 310 CMR 10.00 for that area.3. that proposed work within the buffer zone will contribute to the protection of the
interests identified in M.G.L. c. 131, § 40, except that proposed work which lies bothwithin the riverfront area and within all or a portion of the buffer zone to another
resource area shall comply with the performance standards for riverfront areas at 310
CMR 10.58. For minor activities as specified in 310 CMR 10.02(2)b.1. within the
riverfront area or the buffer zone to another resource area, the Department has
determined that additional conditions are not necessary to contribute to the protection of
the interests identified in M.G.L. c. 131, § 40.
(b) Any person who requests the issuing authority to regulate work taking place outside an
Area Subject to Protection Under M.G.L. c. 131, § 40 and outside the Buffer Zone has the
burden of demonstrating to the satisfaction of the issuing authority that the work has in fact
altered an Area Subject to Protection Under M.G.L. c. 131, § 40.
(2) Burden of Going Forward. The burden of going forward means having to produce at least
some credible evidence from a competent source in support of the position taken. This burden
shall be upon the person contesting the Department's position when the Department has been
requested to hold an adjudicatory hearing. In the event that under the provisions of 310 CMR
10.03 two or more persons have the burden of going forward, said burden may be placed on all
or any number of them, in the discretion of the hearing officer.
(3) Presumption Concerning 310 CMR 15.000: Subsurface Disposal of Sanitary Sewage (Title
5). A subsurface sewage disposal system that is to be constructed in compliance with the
requirements of 310 CMR 15.000 Subsurface Disposal of Sanitary Sewage (Title 5), or more
stringent local board of health requirements, shall be presumed to protect the eight interests
identified in M.G.L. c. 131, § 40, but only if none of the components of said system is located
within the following resource areas:
(a) Coastal.
1. coastal bank
2. coastal beach
3. coastal dune
4. salt marsh
(b) Inland.
1. wet meadows creek
2. marsh bordering river
3. swamp on any stream
4. bog pond
lake
and only if the soil absorption system of said system is set back at least 50 feet horizontally from
the boundary of said areas, as required by 310 CMR 15.211 (Title 5), or a greater distance as may
be required by more stringent local ordinance, by-law or regulation. To protect wildlife habitat
within riverfront areas, the soil absorption system shall not be located within 100 feet of the
mean annual high-water line unless there is no alternative location on the lot which conforms to
Wetland Regulations – May 2008 Page 7
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.03: continued
310 CMR 15.000 without requiring a variance as determined by the local Board of Health, with
less adverse effects on resource areas.
This presumption, however, shall apply only to impacts of the discharge from a sewage
disposal system, and not to the impacts from construction of that system, such as erosion and
siltation from the excavation, placement of fill, or removal of vegetation. Impacts from
construction shall be minimized by the placement of erosion and sedimentation controls during
excavation, limiting the placement of fill, confining the removal of vegetation to that necessary
for the footprint of the system, and taking other measures deemed necessary by the issuing
authority.
The setback distance specified above shall be determined by measuring from the boundary
of the area in question, from the contour at the mean annual flood elevation in inland areas, orfrom the top of a coastal bank or the contour at the highest spring tide elevation in coastal areas,
whichever is further from the water body.The setback distance specified above shall not be required for the renovation or replacement(but is required for the substantial enlargement) of septic systems constructed prior to theeffective date of 310 CMR 10.00, provided no alternative location is available on the lot andsuch work has been approved by the local board of health or the Department, as required by law.This presumption may be overcome only by credible evidence from a competent source that
compliance with 310 CMR 15.000: Subsurface Disposal of Sanitary Sewage (Title 5) or morestringent local requirements will not protect the interests identified in M.G.L. c. 131, § 40.
(4) Presumption Concerning Point-source Discharges. If the Department has issued a permit
pursuant to M.G.L. c. 21, § 43, in conjunction with a federal NPDES (National Pollutant
Discharge Elimination System) permit for any new point-source discharge of pollutants, or will
issue such a permit, prior to commencement of the discharge, the effluent limitations established
in the permit shall be presumed to protect the eight interests identified in M.G.L. c. 131, § 40
with respect to the effects of the discharge on water quality. The permit and any subsequent
amendments thereto shall be referenced in the Order and deemed incorporated therein.
This presumption shall apply only to impacts of the discharge from the source, and not to
impacts from construction of the source.
This presumption may be overcome only by credible evidence from a competent source that
said effluent limitations will not protect the interests identified in M.G.L. c. 131, § 40.
(5) Presumption of Significance. Each Area Subject to Protection Under M.G.L. c. 131, § 40
is presumed to be significant to one or more of the interests identified in M.G.L. c. 131, § 40.
These presumptions are rebuttable and are set forth in 310 CMR 10.21 through 10.60.
For riverfront areas, the issuing authority may find that the presumptions of significance are
partially rebutted as provided in 310 CMR 10.58(3).
(6) Presumption Concerning Application of Herbicides.
(a) Any application of herbicides within any Area Subject to Protection Under M.G.L.
c. 131, § 40 or the Buffer Zone associated with a structure or facility which is:
1. existing and lawfully located;
2. used in the service of the public; and
3. used to provide electric, gas, water, telephone, telegraph and other telecommunication
services
shall be presumed to constitute work performed in the course of maintaining such structure
or facility, and shall be accorded the exemption of such work under M.G.L. c. 131, § 40, only
if the application of herbicides to that structure or facility is performed in accordance with
such plans as are required by the Department of Food and Agriculture pursuant to 333 CMR
11.00: Rights of Way Management, effective July 10, 1987.
(b) Any application of herbicides within the Buffer Zone, other than as provided in
310 CMR 10.03(6)(a), shall be presumed not to alter an Area Subject to Protection Under
M.G.L. c. 131, § 40, only if the work is performed in accordance with such plans as are
required by the Department of Food and Agriculture pursuant to 333 CMR 11.00: Rights
of Way Management, effective July 10, 1987. This presumption shall apply only if the
person proposing such activity has requested and obtained a determination of the boundaries
of the Buffer Zone and Areas Subject to Protection Under M.G.L. c. 131, § 40 in accordance
with 310 CMR 10.05(3)(a)1. and 2; and has submitted that determination as part of the
Vegetation Management Plan.
Wetland Regulations – May 2008 Page 8

(c) Any application of herbicides for management of rights of way within a riverfront area
not subject to 310 CMR 10.03 (6)(a) or (b), provided the area is outside any other resource
area and qualifies under the provisions of 310 CMR 10.58(6)(a), shall be accorded an
exemption of such work under M.G.L. c. 131, § 40, provided that the application of
herbicides is performed in accordance with such plans as are required by the Department of
Food and Agriculture pursuant to 333 CMR 11.00: Rights of Way Management.

(b) Specific Provisions for Notice of Intent Fees. In accordance with General Instructions
for Completing a Notice of Intent and Abbreviated Notice of Intent, the minimum submittal
requirements shall include payment of the filing fee specified in 310 CMR 10.03(7)(c). A
conservation commission shall notify, in writing, the appropriate Department Regional
Office and the applicant when the correct filing fee has not been paid to the city or town and
the filing is therefore incomplete. Said notification shall specify the correct fee amount. The
Department shall also notify, in writing, the applicant and the conservation commission when
the fee due to the Department has not been paid to the Department and the filing is therefore
incomplete. Said notification shall specify the fee due to the Department. The fee will be
based on the initial project design as proposed in the Notice of Intent.
1. Disputes over Notice of Intent Filing Fees. Whenever the conservation commission
or the Department determines that an inadequate fee has been paid, the time period for
the conservation commission or the Department to act shall be stayed until the balance
of the fee is paid.
a. Where, in the opinion of the conservation commission or the Department, less
than the full filing fee has been included with the Notice of Intent, the Notice shall
be deemed complete (assuming all other minimum submittal requirements have been
met), and the stay shall be lifted, upon payment of the additional fee specified by the
Department or the conservation commission. If the applicant has disputed all or a
part of the balance of the fee, after issuance of a Final Order which resolves the fee
dispute, in favor or the applicant any disputed funds paid by the applicant in excess
of the filing fee as determined in the Final Order shall be paid to the applicant by the
Commonwealth and the city or town.
b. In lieu of paying any disputed amount of the filing fee, the applicant may file a
Request for Determination of Applicability under 310 CMR 10.05(3)(a), with
sufficient information to enable the conservation commission to determine the extent
of the area, or the type and extent of the activity, subject to protection under M.G.L.

Intent for proposed work, an applicant generally should file an Abbreviated Notice of
Resource Area Delineation. Alternatively, the boundary of bordering vegetated wetland
(or other resource areas) may be determined through the filing of a Notice of Intent. For
work within riverfront areas, an applicant may submit to the conservation commission
by certified mail or hand delivery a Request for Determination of Applicability to identify
the scope of alternatives to be evaluated under 310 CMR 10.58(4)(c)2., including
sufficient information to enable the conservation commission to determine the applicable
scope.
2. Any person who proposes to perform work within the Buffer Zone shall submit to the
conservation commission either a Notice of Intent for such work or a Request for
Determination of Applicability. Said request shall include sufficient information, asrequired on Form 1, to enable the conservation commission to find and view the area and
to determine whether the proposed work will alter an Area Subject to Protection UnderM.G.L. c. 131, § 40. Applicants may use the Abbreviated Notice of Resource AreaDelineation to confirm the boundaries of resource areas and the buffer zone and to certifythat the requirements of 310 CMR 10.02(2)(b)2. have been met for waiver of review foractivities in the buffer zone.Any person who proposes to apply herbicides in the Buffer Zone pursuant to the
presumption of 310 CMR 10.03(6)(b) shall be required only to submit a request fordetermination of the boundaries of the Buffer Zone and the Areas Subject to Protection
Under M.G.L. c. 131, § 40. Such Request for Determination shall be submitted prior to
the filing of the Vegetation Management Plan, as required by 333 CMR 11.00, on maps
of a scale which will enable the issuing authority to find and delineate those Areas
Subject to Protection Under M.G.L. c. 131, § 40 identified in 310 CMR 10.02(1)(a)
through (c) and the Buffer Zone identified in 310 CMR 10.02(2) within the vicinity of
the project area.
3. A request for a Determination of Applicability shall include certification that the
Department and the owner of the area subject to the request, if the person making the
request is not the owner, have been notified that a determination is being requested under
M.G.L. c. 131, § 40.
(b) Determination of Applicability.
1. Within 21 days after the date of receipt of the Request for a Determination of
Applicability, the conservation commission shall issue a Determination of Applicability,
Form 2. Notice of the time and place of the public meeting at which the determination
will be made shall be given by the conservation commission at the expense of the person
making the request not less than five days prior to such meeting, by publication in a
newspaper of general circulation in the city or town in which the land is located, and by
mailing a notice to the person making the request, the owner, the board of health and the
planning board of said city or town. Notice shall also be given in accordance with the
open meeting law, M.G.L. c. 39, § 23B. Said determination shall be signed by a majority
of the conservation commission, and copies thereof shall be sent by the conservation
commission to the Department, to the person making the request, and to the owner.
Delivery of the copy to the person making the request shall be by hand delivery or
certified mail, return receipt requested. Said determination shall be valid for three years
from the date of issuance, except that a determination of the boundaries of the Areas
Subject to Protection Under M.G.L. c. 131, § 40 and the Buffer Zone which are to apply
to such plans as are required by the Department of Food and Agriculture pursuant to
333 CMR 11.00: Rights of Way Management, effective July 10, 1987, shall be valid
throughout the effective duration of the Vegetation Management Plan.
2. The conservation commission shall find that M.G.L. c. 131, § 40 applies to the land,
or a portion thereof, if it is an Area Subject to Protection Under M.G.L. c. 131, § 40 as
defined in 310 CMR 10.02(1). The conservation commission shall find that M.G.L.
c. 131, § 40 applies to the work, or portion thereof, if it is an Activity Subject to
Regulation Under M.G.L. c. 131, § 40 as defined in 310 CMR 10.02(2). The
conservation commission shall identify the scope of alternatives to be evaluated, if
requested, for work within riverfront areas under 310 CMR 10.58(4)(c)2..
3. A Notice of Intent which is filed as a result of a positive determination, whether such
determination is made by the Department or a conservation commission, shall be filed
with the conservation commission, and all of the procedures set forth in 310 CMR
10.05(4) shall apply.

(c) Appeal to the Department. Following a positive or negative Determination of
Applicability, the identification of the scope of alternatives for work within the riverfront
area, or the failure of a conservation commission to make a determination within 21 days,
any person specified in 310 CMR 10.05(7) may, within ten days, request the Department to
issue a Superseding Determination of Applicability pursuant to the procedures set forth in
310 CMR 10.05(7). The Department shall issue its determination within 35 days from
receipt of such request.
(d) Work Pending Appeal of Determination.
1. Upon a positive Determination of Applicability by a conservation commission, work
may not proceed until the Department or the Commissioner issues a negative
determination, or until a Notice of Intent has been filed, a final order has been issued andrecorded, and all administrative appeal periods have elasped, except that a Notice of
Intent shall not be required for the application of herbicides in accordance with 310 CMR10.03(6).2. Upon a positive Determination of Applicability by the Department, work may notproceed until the Commissioner issues a negative determination or until a Notice of
Intent has been filed, a final order has been issued and recorded, and all administrativeappeal periods have elapsed.
3. Upon a positive Determination of Applicability by the Commissioner, work may not
proceed until a judicial determination is made that the proposed work is not subject to
M.G.L. c. 131, § 40 or until a Notice of Intent has been filed and a final order has been
issued and recorded, and all administrative appeal periods have elapsed.
4. Upon a negative Determination of Applicability by a conservation commission or
upon the failure of a conservation commission to act within the 21 day time period, and
where the Department has been requested to issue a Superseding Determination of
Applicability but has failed to do so within 35 days, work may proceed at the owner's risk
upon notice to the Department and to the conservation commission.
5. Upon a negative Determination of Applicability by the Department, work may
proceed at the owner's risk even if a request for an adjudicatory hearing has been made.
6. Upon a negative Determination of Applicability by the Commissioner after an
adjudicatory hearing, work may proceed at the owner's risk even if a petition for judicial
review has been filed.
7. Upon a positive Determination of Applicability by a conservation commission, the
Department, or the Commissioner which identifies the scope of alternatives to be
evaluated under 310 CMR 10.58(4)(c)2. for work within the riverfront area, work may
not proceed until a Notice of Intent has been filed and a final Order has been issued and
recorded and all administrative appeal periods have elapsed.
(4) Notices of Intent.
(a) Any person who proposes to do work that will remove, fill, dredge or alter any Area
Subject to Protection Under M.G.L. c. 131 § 40 shall file a Notice of Intent on Form 3 and
other application materials in accordance with the submittal requirements set forth in the
General Instructions for Completing Notice of Intent (Form 3) and Abbreviated Notice of
Intent (Form 4). If the applicant and landowner are not the same, an applicant shall obtain
written permission from the landowner(s) prior to filing a Notice of Intent for proposed work,
except for work proposed on Great Ponds or Commonwealth tidelands. Two copies of the
completed Notice of Intent with supporting plans and documents shall be sent by certified
mail or hand delivery to the conservation commission, and one copy of the same shall be sent
concurrently in like manner to the Department.
Wetland Regulations – May 2008 Page 28

10.05: continued
Concurrent with the filing of the Notice of Intent, the applicant also shall provide
notification to all abutters and any property owner within 100 feet of the property line of the
land where the activity is proposed including if separated from that land by a public or
private street or a body of water and not unreasonably distant from the project site. The
applicant shall provide notification at the mailing addresses shown on the most recent
applicable tax list from the municipal assessor. Notification shall be at the applicant’s
expense. The notification shall state where copies of the Notice of Intent may be examined
or obtained and where information on the date, time, and location of the public hearing may
be obtained. To ensure compatibility with local procedures, applicants must comply with any
rules of the local conservation commission pertaining to the location for examining or
obtaining the Notice of Intent and information about the hearing. The applicant shall notifyabutters in writing by hand delivery or certified mail, return receipt requested, or by
certificates of mailing. Mailing at least seven days prior to the public hearing shall constitutetimely notice. The applicant shall present either the certified mail receipts or certificate ofmailing receipts for all abutters at the beginning of the public hearing. The presentation ofthe receipts for all abutters identified on the tax list shall constitute compliance with abutternotification requirements. The conservation commission shall determine whether theapplicant has complied with abutter notification requirements. The Department will dismiss
Requests for Action based on allegations of failure to comply with abutter notificationrequirements, absent a clear showing by an abutter seeking Department action that the
applicant failed to notify the abutter.
(b) For certain purposes, other forms of Notices may be used.
1. For certain projects, applicants may at their option use the Abbreviated Notice of
Intent. This latter form may only be used when all three of the following circumstances
exist:
a. the proposed work is within the Buffer Zone, as defined in 310 CMR 10.04, or
within Land Subject to Flooding, as defined in 310 CMR 10.57(2) or within the
Riverfront Area, as defined in 310 CMR 10.58.
b. the proposed work will disturb less than 1000 square feet of surface area within
the Buffer Zone and/or Land Subject to Flooding or less than 1000 square feet of
riverfront area, provided the work conforms to 310 CMR 10.58(4)(c)2.a..
c. the proposed work will not require U.S. Army Corps of Engineer Section 10 or
Section 404 permits, or a license from the Division of Waterways pursuant to M.G.L.
c. 91.
2. To establish the extent of bordering vegetated wetland and/or other resource areas on
land subject to protection under M.G.L. c. 131, § 40, applicants may use the Abbreviated
Notice of Resource Area Delineation for the confirmation of a delineated boundary of
bordering vegetated wetlands and/or other resource areas on the site, prior to filing a
Notice of Intent for proposed work. Alternatively, the boundary of bordering vegetated
wetland or other resource areas may be determined through the filing of a Notice of
Intent.
3. To confirm the boundaries of resource areas and certify that the requirements of
310 CMR 10.02(2)(b)2. will be met for activities in the Buffer Zone, applicants shall use
the Abbreviated Notice of Resource Area Delineation. When an applicant obtains an
Order of Resource Area Delineation for a project eligible for simplified review under
310 CMR 10.02(2)(b)2. that requires concurrence that the stormwater management plan
conforms to the Stormwater Management Standards as provided in 310 CMR 10.05(6)(k)
through (q) and that the requirements of 310 CMR 10.02(2)(b)2. f, g, and h. have been
met, the applicant shall submit the stormwater management plans and any subsequent
plan revisions to the conservation commission. The conservation commission shall act
within 30 days and either concur that the stormwater management plan conforms to the
Stormwater Management Standards as provided in 310 CMR 10.05(6)(k) through (q) and
the requirements of 310 CMR 10.02(2)(b)2.f., g., and h. have been met or not concur,
specifying which of the Stormwater Management Standards or other requirements are not
met and direct the applicant to file a Request for Determination of Applicability or a
Notice of Intent.

(c) Upon receipt of the application materials referred to in 310 CMR 10.05(4)(a), the
Department shall issue a file number. The designation of a file number shall not imply that
the plans and supporting documents have been judged adequate for the issuance of an Order,
but only that copies of the minimum submittal requirements contained in the General
Instructions have been filed.
(d) In the event that only a portion of a proposed project or activity lies within an Area
Subject to Protection Under M.G.L. c. 131, § 40 or within the Buffer Zone, and the
remainder of the project or activity lies outside those areas, only that portion within those
areas must be described in the detail called for by the General Instructions and Form 3 and
4; provided, however, that in such circumstances the Notice of Intent shall also contain a
description and calculation of peak flow and estimated water quality characteristics ofdischarge from a point source (both closed and open channel) when the point of discharge
falls within an Area Subject to Protection Under M.G.L. c. 131, § 40 or within the BufferZone.Notwithstanding the foregoing, when the issuing authority has determined that an activityoutside the Areas Subject to Protection Under M.G.L. c. 131, § 40 and outside the BufferZone has in fact altered an Area Subject to Protection Under M.G.L. c. 131, § 40, it mayrequire such plans, supporting calculations and other documentation as are necessary to
describe the entire activity.(e) The requirement under M.G.L. c. 131, § 40 to obtain or apply for all obtainable permits,
variances and approvals required by local by-law with respect to the proposed activity shall
mean only those which are feasible to obtain at the time the Notice of Intent is filed. Permits,
variances, and approvals required by local by-law may include, among others, zoning
variances, permits from boards of appeals, permits required under floodplain or wetland
zoning by-laws and gravel removal permits. They do not include, among others, building
permits under the State Building Code, M.G.L. c. 23B, § 16, or subdivision control approvals
under the State Subdivision Control Law, M.G.L. c. 41, §§ 81K through 81GG, which are
issued by local authorities. When an applicant for a comprehensive permit (under
M.G.L. c. 40B, §§ 20 through 23) from a board of appeals has received a determination from
the board granting or denying the permit and, in the case of a denial, has appealed to the
Housing Appeals Committee (established under M.G.L. c. 23B, § 5A), said applicant shall
be deemed to have applied for all permits obtainable at the time of filing.
(f) If the issuing authority rejects a Notice of Intent because of a failure to obtain or apply
for all permits, variances and approvals required by local by-law, it shall specify in writing
the permit, variance or approval that has not been applied for. A ruling by the municipal
agency within whose jurisdiction the issuance of the permit, variance or approval lies, or by
the town counsel or city solicitor, concerning the applicability or obtainability of such permit,
variance or approval shall be accepted by the issuing authority. In the absence of such a
ruling, other evidence may be accepted.
(g) A Notice of Intent shall expire where the applicant has failed to diligently pursue the
issuance of a Final Order in proceedings under 310 CMR 10.00. A Notice of Intent shall be
presumed to have expired two years after the date of filing unless the applicant submits
information showing that (a) good cause exists for the delay of proceedings under 310 CMR
10.00; and (b) the applicant has continued to pursue the project diligently in other forums in
the intervening period; provided, however, that unfavorable financial circumstances shall not
constitute good cause for delay. No Notice of Intent shall be deemed expired under
310 CMR 10.05 when an adjudicatory hearing is pending and when the applicant has
provided all information necessary to continue with the prosecution of the case.
Notwithstanding the provisions contained in 310 CMR 10.10, 310 CMR 10.05(4)(g) shall
apply to any Notice of Intent whenever filed.
(h) The issuing authority may require that supporting plans and calculations be prepared and
stamped by a registered professional engineer (PE) when, in its judgment, the complexity of
the proposed work warrants this professional certification. The issuing authority may also
require the preparation of supporting materials by other professionals including, but not
limited to, registered landscape architect, registered land surveyor, environmental scientist,
geologist or hydrologist when in its judgment the complexity of the proposed work warrants
the relevant specialized expertise. The issuing authority may require a delineation or a
certification under 310 CMR 10.02(2)(b)2. in an Abbreviated Notice of Resource Area
Delineation to be performed by a professional with relevant specialized expertise.

(5) Public Hearings by Conservation Commissions.
(a) A public hearing shall be held by the conservation commission within 21 days of receipt
of the minimum submittal requirements set forth in the General Instructions for Completing
Notice of Intent (Form 3), Abbreviated Notice of Intent (Form 4) and Abbreviated Notice of
Resource Area Delineation, and shall be advertised in accordance with M.G.L. c. 131, § 40
and the requirements of the open meeting law, M.G.L. c. 39, § 23B.
(b) Public hearings may be continued as follows:
1. without the consent of the applicant to a date, announced at the hearing, within 21
days, of receipt of the Notice of Intent;
2. with the consent of the applicant, to an agreed-upon date, which shall be announced
at the hearing; or3. with the consent of the applicant for a period not to exceed 21 days after the
submission of a specified piece of information or the occurrence of a specified action.The date, time and place of said continued hearing shall be publicized in accordance withM.G.L. c. 131, § 40, and notice shall be sent to any person at the hearing who so requestsin writing.
(6) Orders of Conditions Regulating Work and Orders of Resource Area Delineation.
(a) Within 21 days of the close of the public hearing, the conservation commission shalleither:
1. make a determination that the area on which the work is proposed to be done, or
which the proposed work will remove, fill, dredge or alter, is not significant to any of the
interests identified in M.G.L. c. 131, § 40, and shall so notify the applicant and the
Department on Form 6;
2. make a determination that the area on which the work is proposed to be done, or
which the proposed work will remove, fill, dredge or alter, is significant to one or more
of the interests identified in M.G.L. c. 131, § 40, and shall issue an Order of Conditions
for the protection of said interest(s), on Form 5; or
3. make a determination that bordering vegetated wetland and other resource areas
subject to jurisdiction have been identified and delineated according to the definitions in
310 CMR 10.00 and shall issue an Order of Resource Area Delineation to confirm or
modify the delineations submitted. The Order of Resource Area Delineation shall be
effective for three years.
The standards and presumptions to be used by the issuing authority in determining
whether an area is significant to the interests identified in M.G.L. c. 131, § 40 are found in
310 CMR 10.21 through 10.37 (for coastal wetlands) and 310 CMR 10.51 through 10.60 (for
inland wetlands).
(b) The Order of Conditions shall impose such conditions as are necessary to meet the
performance standards set forth in 310 CMR 10.21 through 10.60 for the protection of
those areas found to be significant to one or more of the interests identified in
M.G.L. c. 131, § 40 and the Stormwater Management Standards provided in 310 CMR
10.05(6)(k) through (q). The Order shall prohibit any work or any portion thereof that
cannot be conditioned to meet said standards.
The Order shall impose conditions only upon work or the portion thereof that is to
be undertaken within an Area Subject to Protection Under M.G.L. c. 131, § 40 or within
the Buffer Zone. The Order shall impose conditions to control erosion and sedimentation
within resource areas and the Buffer Zone. The Order shall impose conditions setting
limits on the quantity and quality of discharge from a point source (both closed and open
channel), when said limits are necessary to protect the interests identified in
M.G.L. c. 131, § 40; provided, however, that the point of discharge falls within an Area
Subject to Protection Under M.G.L. c. 131, § 40 or within the Buffer Zone, and further
provided that said conditions are consistent with the limitations set forth in 310 CMR
10.03(4).
Notwithstanding the foregoing, when the issuing authority has determined that an
Activity outside the Areas Subject to Protection Under M.G.L.131. § 40 and outside the
Buffer Zone has in fact altered an Area Subject to Protection Under M.G.L.c. 131,§ 40,
it shall impose such conditions on any portion of the activity as are necessary to
contribute to the protection of the interests identified in M.G.L.c. 131, § 40.
Wetland Regulations – May 2008 Page 31

10.05: continued
(c) If the conservation commission finds that the information submitted by the applicant is
not sufficient to describe the site, the work or the effect of the work on the interests identified
in M.G.L. c. 131, § 40, it may issue an Order prohibiting the work. The Order shall specify
the information which is lacking and why it is necessary.
(d) Except as provided in M.G.L. c. 131, § 40 for maintenance dredging, an Order of
Conditions, Order of Resource Area Delineation, or Notification of Non-significance shall
be valid for three years from the date of its issuance; provided, however, that the issuing
authority may issue an Order for up to five years where special circumstances warrant and
where those special circumstances are set forth in the Order. An Order of Resource Area
Delineation shall be valid for three years, and may be extended by the issuing authority for
one or more years up to three years each under 310 CMR 10.05(8) upon written confirmationby a professional with relevant expertise that the resource area delineations remain accurate.
(e) The Order or Notification of Non-significance shall be signed by a majority of theconservation commission and shall be mailed by certified mail (return receipt requested) orhand delivered to the applicant or his agent or attorney, and a copy mailed or hand deliveredat the same time to the Department. If the Order imposes conditions necessary to meet anyperformance standard contained in 310 CMR 10.37 or 10.59, a copy shall be mailed or handdelivered at the same time to the Massachusetts Natural Heritage and Endangered Species
Program. (f) A copy of the plans describing the work and the Order shall be kept on file by the
conservation commission and by the Department, and shall be available to the public at
reasonable hours.
(g) Prior to the commencement of any work permitted or required by the Final Order,
including a Final Order of Resource Area Delineation, or Notification of Non-significance,
the Order or Notification shall be recorded in the Registry of Deeds or the Land Court for the
district in which the land is located, within the chain of title of the affected property.
Recording of an Order of Resource Area Delineation is not required where no work is
performed under 310 CMR 10.02(2)(b)2. In the case of recorded land, the final order shall
also be noted in the Registry's Grantor Index under the name of the owner of the land upon
which the proposed work is to be done. In the case of registered land, the final order shall
also be noted on the Land Court Certificate of Title of the owner of the land upon which the
proposed work is to be done. Certification of recording shall be sent to the issuing authority
on the form at the end of Form 5. If work is undertaken without the applicant first recording
the Order, the issuing authority may issue an Enforcement Order (Form 9) or may itself
record the Order of Conditions.
(h) Notwithstanding the provisions contained in 310 CMR 10.10(1) and (3), any Order of
Conditions not containing an expiration date, issued for work proposed in a Notice of Intent
filed under M.G.L. c. 131, § 40 prior to November 18, 1974, shall expire on April 17, 1986.
(i) An Order of Conditions does not grant any property rights or any exclusive privileges;
it does not authorize any injury to private property or invasion of property rights.
(j) Failure to comply with conditions stated in the Order and with all related statutes and
other regulatory measures shall be deemed cause to revoke or modify the Order of
Conditions.
(k) No Area Subject to Protection Under M.G.L. c. 131, § 40 other than bordering land
subject to flooding, isolated land subject to flooding, land subject to coastal storm flowage,
or riverfront area may be altered or filled for the impoundment or detention of stormwater,
the control of sedimentation or the attenuation of pollutants in stormwater discharges, and
the applicable performance standards shall apply to any such alteration or fill. Except as
expressly provided, stormwater runoff from all industrial, commercial, institutional, office,
residential and transportation projects that are subject to regulation under M.G.L.c. 131, § 40
including site preparation, construction, and redevelopment and all point source stormwater
discharges from said projects within an Area Subject to Protection under M.G.L.c. 131, § 40
or within the Buffer Zone shall be provided with stormwater best management practices to
attenuate pollutants and to provide a setback from the receiving waters and wetlands in
accordance with the following Stormwater Management Standards as further defined and
specified in the Massachusetts Stormwater Handbook:
1. No new stormwater conveyances (e.g. outfalls) may discharge untreated stormwater
directly to or cause erosion in wetlands or waters of the Commonwealth.
Wetland Regulations – May 2008 Page 32
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.05: continued
2. Stormwater management systems shall be designed so that post-development peak
discharge rates do not exceed pre-development peak discharge rates. This Standard may
be waived for discharges to land subject to coastal storm flowage as defined in 310 CMR
10.04.
3. Loss of annual recharge to ground water shall be eliminated or minimized through
the use of infiltration measures including environmentally sensitive site design, low
impact development techniques, stormwater best management practices and good
operation and maintenance. At a minimum, the annual recharge from the post-
development site shall approximate the annual recharge from the pre-development
conditions based on soil type.
This Standard is met when the stormwater management system is designed toinfiltrate the required recharge volume as determined in accordance with the
Massachusetts Stormwater Handbook.4. Stormwater management systems shall be designed to remove 80% of the averageannual post-construction load of Total Suspended Solids (TSS). This Standard is metwhen:a. Suitable practices for source control and pollution prevention are identified in along-term pollution prevention plan and thereafter are implemented and maintained;
b. Structural stormwater best management practices are sized to capture the requiredwater quality volume determined in accordance with Massachusetts Stormwater
Handbook; and
c. Pretreatment is provided in accordance with the Massachusetts Stormwater
Handbook.
5. For land uses with higher potential pollutant loads, source control and pollution
prevention shall be implemented in accordance with the Massachusetts Stormwater
Handbook to eliminate or reduce the discharge of stormwater runoff from such land uses
to the maximum extent practicable. If through source control and/or pollution
prevention, all land uses with higher potential pollutant loads cannot be completely
protected from exposure to rain, snow, snow melt and stormwater runoff, the proponent
shall use the specific structural stormwater BMPs determined by the Department to be
suitable for such use as provided in the Massachusetts Stormwater Handbook.
Stormwater discharges from land uses with higher potential pollutant loads shall also
comply with the requirements of the Massachusetts Clean Waters Act, M.G.L. c. 21,
§§ 26 through 53, and the regulations promulgated thereunder at 314 CMR 3.00,
314 CMR 4.00 and 314 CMR 5.00.
6. Stormwater discharges within the Zone II or Interim Wellhead Protection Area of a
public water supply and stormwater discharges near or to any other critical area require
the use of the specific source control and pollution prevention measures and the specific
structural stormwater best management practices determined by the Department to be
suitable for managing discharges to such area as provided in the Massachusetts
Stormwater Handbook. A discharge is near a critical area, if there is a strong likelihood
of a significant impact occurring to said area, taking into account site-specific factors.
Stormwater discharges to Outstanding Resource Waters and Special Resource Waters
shall be removed and set back from the receiving water or wetland and receive the
highest and best practical method of treatment. A “storm water discharge” as defined in
314 CMR 3.04(2)(a)1. or (b) to an Outstanding Resource Water or Special Resource
Water shall comply with 314 CMR 3.00 and 314 CMR 4.00. Stormwater discharges to
a Zone I or Zone A are prohibited, unless essential to the operation of the public water
supply.
7. A redevelopment project is required to meet the following Stormwater Management
Standards only to the maximum extent practicable: Standard 2, Standard 3, and the
pretreatment and structural stormwater best management practice requirements of
Standards 4, 5 and 6. Existing stormwater discharges shall comply with Standard 1 only
to the maximum extent practicable. A redevelopment project shall also comply with all
other requirements of the Stormwater Management Standards and improve existing
conditions.
8. A plan to control construction related impacts including erosion, sedimentation and
other pollutant sources during construction and land disturbance activities (construction
period erosion, sedimentation and pollution prevention plan) shall be developed and
implemented.

9. A long-term operation and maintenance plan shall be developed and implemented to
ensure that the stormwater management system functions as designed.
10. All illicit discharges to the stormwater management system are prohibited.
(l) The Stormwater Management Standards shall not apply to:
1. A single -family house;
2. Housing development and redevelopment projects comprised of detached single-
family dwellings on four or fewer lots, provided that there are no stormwater discharges
that may potentially affect a critical area;
3. Multi-family housing development and redevelopment projects, with four or fewer
units, including condominiums, cooperatives, apartment buildings and townhouses,
provided that there are no stormwater discharges that may potentially affect a criticalarea; and
4. Emergency repairs to roads or their drainage systems.(m) The Stormwater Management Standards shall apply to the maximum extent practicableto the following: 1. Housing development and redevelopment projects comprised of detached single-family dwellings on four or fewer lots that have a stormwater discharge that maypotentially affect a critical area;
2. Multi-family housing developments and redevelopment projects with four or fewerunits, including condominiums, cooperatives, apartment buildings, and townhouses, that
have a stormwater discharge that may potentially affect a critical area;
3. Housing development and redevelopment projects comprised of detached single-
family dwellings, on five to nine lots, provided there is no stormwater discharge that may
potentially affect a critical area; and
4 Multi-family housing development and redevelopment projects, with five to nine
units, including condominiums, cooperatives, apartment buildings and townhouses,
provided there is no stormwater discharge that may potentially affect a critical area.
5. Marinas and boatyards provided that the hull maintenance, painting and service areas
are protected from exposure to rain, snow, snowmelt, and stormwater runoff; and
6. Footpaths bikepaths and other paths for pedestrian and/or nonmotorized vehicle
access.
(n) For phased projects the determination of whether the Stormwater Management
Standards apply is made on the entire project as a whole including all phases. When
proposing a development or redevelopment project subject to the Stormwater Management
Standards, proponents shall consider environmentally sensitive site design that incorporates
low impact development techniques in addition to stormwater best management practices.
(o) Project proponents seeking to demonstrate compliance with some of all of the
Stormwater Management Standards to the maximum extent practicable shall demonstrate
that:
1. They have made all reasonable efforts to meet each of the Standards;
2. They have made a complete evaluation of possible stormwater management measures
including environmentally sensitive site design and low impact development techniques
that minimize land disturbance and impervious surfaces, structural stormwater best
management practices, pollution prevention, erosion and sedimentation control and
proper operation and maintenance of stormwater best management practices; and
3. If full compliance with the Standards cannot be achieved, they are implementing the
highest practicable level of stormwater management.
(p) Notwithstanding anything to the contrary in 310 CMR 10.00, stormwater runoff from
all industrial, commercial, institutional, office, residential and transportation projects subject
to regulation under M.G.L. c. 131, § 40, including site preparation, construction, and
redevelopment, and all point source stormwater discharges from said projects within an Area
Subject to Protection Under M.G.L. c. 131, § 40, or within the Buffer Zone, for which a
Notice of Intent or Notice of Resource Area Delineation has been filed prior to
January 2, 2008 shall be managed according to the Stormwater Management Standards as
set forth in the Stormwater Policy issued by the Department on November 18, 1996.

2. the owner, if not the applicant;3. any person aggrieved by a Determination or an Order;4. any owner of land abutting the land on which the work is to be done;5. any ten residents of the city or town where the land is located; and
6. the Department.(b) Any person(s) permitted to request the Department to act under 310 CMR 10.05(7)(a)
may request the Department to issue a Superseding Determination of Applicability or to issue
a Superseding Order, whichever is appropriate, whenever a conservation commission has:
1. issued a Determination of Applicability (Form 2);
2. issued a Notification that an area is not significant to any interest identified in M.G.L.
c. 131, § 40 (Form 6);
3. issued an Order of Conditions allowing, conditioning or prohibiting work (Form 5)
or an Order of Resource Area Delineation; or
4. failed to hold a public hearing or issue an Order, Notification or Determination within
the time period required by M.G.L. c. 131, § 40.
Where the Department is requested to issue a Superseding Determination or Order of
Conditions, the conservation commission shall be a party to all agency proceedings and
hearings before the Department.
(c) A request for a Superseding Order or Determination shall be made in writing and shall
be sent by certified mail or hand delivered within ten days of issuance of the Order,
Determination or Notification which is being appealed. When the basis of such request is
the conservation commission's failure to act, the request may be made at any time up to 70
days after the expiration of the period within which the conservation commission was to have
acted. Said request shall state clearly and concisely the objections to the Order,
Determination or Notification which is being appealed and, in the case of a request for a
Superseding Order, how the Order of Conditions or Notification of Non-Significance issued
by the conservation commission is inconsistent with 310 CMR 10.00 and does not contribute
to the protection of the interests identified in M.G.L. c. 131, § 40.
(d) All requests for the Department to act shall be sent to the appropriate Regional Office
of the Department. A copy of the request shall at the same time be sent by certified mail or
hand delivered to the conservation commission and the applicant, if he is not the appellant.
(e) Within 35 days from receipt of such a request, the Department shall issue a Superseding
Determination of Applicability (Form 2) or a Notification that an area is not significant to
any interest identified in M.G.L. c. 131, § 40 (Form 6).
(f) Within 70 days from receipt of such a request, the Department shall issue a Superseding
Order unless either of the following apply, or in the event that both apply, whichever is later:
1. compliance with M.G.L. c. 30, §§ 61 through 62H and 301 CMR 11.00 is required,
in which case the Department shall issue a Superseding Order within 40 days of the
issuance of a statement by the Secretary of the Executive Office of Environmental Affairs
that the applicant has complied with M.G.L. c. 30, §§ 6 through 62H and 301 CMR
11.00;
2. the Department has requested additional plans, information or documentation
pursuant to 310 CMR 10.05(7)(g), in which case the Department shall issue a
Superseding Order within 40 days of receipt of such plans, information, or
documentation, or of the failure of the applicant to comply with such request.

(g) The Department shall notify the applicant within 30 days of receipt of a request for the
Department to act if additional information or documentation is necessary to make its
determination; provided, however, that further information may be requested should the
information supplied in response to the original notification so require. When requested to
issue a Superseding Order of Resource Area Delineation, the Department shall limit its
review to the resource area delineations or any other requirements subject to confirmation
under 310 CMR 10.02(2)(b)2. The Department shall consider the objections to the resource
area delineations stated in the request. The Department may affirm an Order of Resource
Area Delineation based upon a conclusion that the Order of Resource Area Delineation
substantially conforms to the locations identified by the Department through a site
inspection. (h) When the request for a Superseding Order concerns an Order prohibiting work and
issued pursuant to 310 CMR 10.05(6)(c), the Department shall limit its review to theinformation submitted to the conservation commission. If the Department determines thatinsufficient information was submitted, it shall affirm the denial and instruct the applicantto refile with the conservation commission and include the appropriate information. If theDepartment determines that sufficient information was submitted, it shall so inform theapplicant and the conservation commission, and shall proceed to issue a Superseding Order
as provided in 310 CMR 10.05.(i) After receipt of a request for a Superseding Determination or Order, the Department may
conduct an informal meeting and may conduct an inspection of the site. In the event an
inspection is conducted, all parties shall be invited in order to present any information
necessary or useful to a proper and complete review of the proposed activity and its effects
upon the interests identified in M.G.L. c. 131, § 40. Any party presenting information as a
result of such a meeting shall provide copies to the other parties. Based upon its review of
the Notice of Intent, the Order, any informal meeting or site inspection, and any other
additional plans, information, or documentation submitted under 310 CMR 10.05(7)(f) or
(g), the Department may issue a Superseding Order which affirms the Order issued by the
conservation commission.
(j) 1. Timely Filings. Papers required or permitted to be filed under 310 CMR 10.05 must
be filed with the Department, at the address designated in the Reviewable Decision,
within the timelines specified in 310 CMR 10.05. Papers shall be considered filed as set

where the land is located, if at least one resident was previously a participant in the
permit proceeding may request review of a Reviewable Decision by filing an Appeal
Notice no later than ten business days after the issuance of the Reviewable Decision.
Previously participating in the permit proceeding means the submission of written
information to the conservation commission prior to close of the public hearing,
requesting an action by the Department that would result in a Reviewable Decision,
or providing written information to the Department prior to issuance of a Reviewable
Decision. The Appeal Notice must be filed with the Department with a copy sent to
the appropriate regional Department office by certified mail or hand delivered within

must at the same time be sent by certified mail or hand delivered to the conservation
commission (if not filed by the conservation commission) and to the applicant (if not
filed by the applicant). The Appeal Notice shall also be served by certified mail or
hand delivered on any person that requested the action by the Department that
resulted in the Reviewable Decision. In the event that the entity that requested the
action is a ten resident group, the Appeal Notice shall be served on the designated
representative of the ten resident group, whose name and contact information shall
be included in the Reviewable Decision. Any party listed in 310 CMR
10.05(7)(j)2.a. that fails to timely file an Appeal Notice pursuant to 310 CMR 10.05,

adjust the schedule either by extending it up to 30 days, or by taking the matter ahead
of other cases.
g. All parties must attend and be prepared to discuss settlement and the narrowing
of issues at the pre-screening conference. At the conclusion of the pre-screening
conference or shortly thereafter, the Presiding Officer shall prepare and circulate a
prescreening conference report, for any appeal not resolved in prescreening. The
prescreening conference report shall contain a list of issues that are in dispute and
which are legally relevant, and that are to be addressed in the parties’ direct and
rebuttal cases.
h. The Presiding Officer shall conduct a hearing. At the hearing, the parties’ Direct
Cases shall consist of, and be limited to, the evidence contained in their respective

(10) Variance.(a) The Commissioner may waive the application of any regulation(s) in 310 CMR 10.21through 10.60 when he finds that:1. there are no reasonable conditions or alternatives that would allow the project to
proceed in compliance with 310 CMR 10.21 through 10.60;2. that mitigating measures are proposed that will allow the project to be conditioned
so as to contribute to the protection of the interests identified in M.G.L. c. 131, § 40; and
3. that the variance is necessary to accommodate an overriding community, regional,
state or national public interest; or that it is necessary to avoid an Order that so restricts
the use of property as to constitute an unconstitutional taking without compensation.
(b) Procedure. A request for a variance shall be made in writing and shall include, at a
minimum, the following information:
1. a description of alternatives explored that would allow the project to proceed in
compliance with 310 CMR 10.21 through 10.60 and an explanation of why each is
unreasonable;
2. a description of the mitigating measures to be used to contribute to the protection of
the interests identified in M.G.L. c. 131, § 40; and
3. evidence that an overriding public interest is associated with the project which
justifies waiver of 310 CMR 10.21 through 10.60, or evidence that the Superseding
Order so restricts the use of the land that it constitutes an unconstitutional taking without
compensation.
The request for a variance shall be sent to the Department by certified mail or hand
delivered and a copy thereof shall at the same time be sent by certified mail or hand delivered
to the conservation commission and any other parties.
The Department will place a notice in the Environmental Monitor published by the
Massachusetts Environmental Policy Act Office of the Executive Office of Environmental
Affairs to solicit public comments on the request. The Department shall conduct a public
hearing on a request for a variance. After reviewing the information submitted with the
request for a variance and any other information submitted by any party within the public
comment period, the Commissioner shall issue a decision as to whether to grant the variance.
Within ten days of the date of issuance of the Commissioner’s decision on the variance, any
person who submitted comments during the public comment period may, according to the
procedures specified in 310 CMR 10.05(7)(j), request an adjudicatory hearing on the
decision. On a request for a variance based on overriding public interest, the Commisisoner
may dismiss the request to hold an adjudicatory hearing if the request repeats matters
adequately considered in the variance decision, renews claims or arguments previously
raised, or attempts to raise new claims or arguments not raised during the public comment
period. On a request for a variance to avoid restrictions that would constitute an
unconstitutional taking, the Commissioner shall hold an adjudicatory hearing. If an
adjudicatory hearing is held, the applicant has the burden of demonstrating that the project
meets the criteria necessary for a variance. Other parties to the adjudicatory hearing may
introduce evidence either in favor of or opposing the request for a variance.

For projects in which all of the proposed work will be undertaken on land within the
boundaries of one city or town, the request for a variance shall not be filed until the applicant
first files a Notice of Intent with the Conservation Commission. The Commission shall
review the project in accordance with the procedures set forth in 310 CMR 10.01 through
10.10 and issue an Order of Conditions consistent with 310 CMR 10.21 through 10.60.
Within ten days of the issuance of the Order of Conditions, the applicant may request the
Department to issue a Superseding Order. The Department staff shall review the project in
accordance with the procedures set forth in 310 CMR 10.01 through 10.10 and shall issue
a Superseding Order consistent with the provisions of 310 CMR 10.21 through 10.60.
Within ten days of the issuance of the Superseding Order, the applicant may request an
adjudicatory hearing on that order and/or a variance under 310 CMR 10.05(10) according tothe procedure previously described.
For projects in which the proposed work will be undertaken on land within theboundaries of more than one city or town, the applicant may file a request for a variancedirectly with the Commissioner, with a copy to each affected conservation commission. If,after public notice, the Commissioner finds that a project meets the variance criteria, he shallspecify which regulation(s) has been waived and what general requirements or conditionsmust be met to satisfy the variance criteria listed in 310 CMR 10.05(10)(a). The applicant
shall then file a Notice of Intent with the appropriate conservation commissions inaccordance with the procedures contained in 310 CMR 10.01 through 10.10. The
conservation commissions shall issue Orders of Conditions consistent with all provisions of
310 CMR 10.21 through 10.60 except those waived by the Commissioner and containing any
additional conditions or requirements imposed by the Commissioner in the variance. The
usual procedures contained in 310 CMR 10.01 through 10.10 for requesting Superseding
Orders and adjudicatory hearings remain applicable.
Commentary
310 CMR 10.05(10), which provides that the Commissioner may waive the application of
one or more of the regulations on the basis of overriding public benefit is intended to be
employed only in rare and unusual cases. The provision authorizing a variance request directly
to the Commissioner for projects on land within more than one city or town is intended to apply
to projects that involve functionally related work in several contiguous towns (e.g., transportation
and energy transmission facilities) and to provide for a single uniform determination concerning
alternative locations and the other variance criteria.
10.06: Emergencies
(1) Any person requesting permission to do an emergency project shall specify why the project
is necessary for the protection of the health or safety of the citizens of the Commonwealth and
what agency of the Commonwealth or subdivision thereof is to perform the project or has
ordered the project to be performed. If the project is certified to be an emergency by the
conservation commission or the Commissioner, the certification shall include a description of
the work which is to be allowed and shall not include work beyond that necessary to abate the
emergency. A site inspection shall be made prior to certification.
(2) An emergency certification shall be issued only for the protection of public health or safety.
(3) The time limitation for performance of emergency work shall not exceed 30 days, or 60 days
for Immediate Response Actions approved by the Bureau of Waste Site Cleanup (BWSC) of the
Department of Environmental Protection in accordance with the provisions of 310 CMR
40.0410, unless written approval of the Commissioner is obtained.
(4) A copy of an emergency certification shall be sent to the Department when it is issued by
a conservation commission, and to the conservation commission when it is issued by the
Department.

(5) The Department may, on its own motion or at the request of any person, review: an
emergency certification issued by a conservation commission and any work permitted
thereunder; a denial by a conservation commission of a request for emergency certification; or
the failure by a conservation commission to act within 24 hours of a request for emergency
certification. Such review shall not operate to stay the work permitted by the emergency
certification unless the Department specifically so orders. The Department's review shall be
conducted within seven days of: issuance by a conservation commission of the emergency
certification; denial by a conservation commission of the emergency certification; or failure by
a conservation commission to act within 24 hours of a request for emergency certification. If
certification was improperly granted, or the work allowed thereunder is excessive or not required
to protect the health and safety of citizens of the Commonwealth, the Department may revokethe emergency certification, condition the work permitted thereunder, or take such other action
as it deems appropriate.
(6) Agricultural Emergencies(a) Notwithstanding the provisions of 310 CMR 10.06(1) through (4), any person mayundertake work for the emergency agricultural activities described in 310 CMR 10.06(6)(g)when necessary to:
1. eliminate an imminent threat to land in agricultural use;2. restore land in agricultural use that has been damaged due to a storm or other sudden,
unforeseen event; or
3. provide an emergency agricultural water source when the existing agricultural water
source suddenly and unforeseeably has been rendered unusable or unavailable.
(b) Written notice of any work undertaken as an emergency activity under 310 CMR
10.06(6) must be received by the conservation commission and mailed to the Department
within three days after the work has commenced or within three days after the end of the
emergency event, whichever is sooner. Such notice shall state the name of the person
performing the work, the name of the property owner (if different), the property and the
location on the property where the work is to be performed, the exact nature of the
emergency and of the work which is to be performed, and when the work was begun and
when it is expected to be completed. The commission may, at its discretion, conduct a site
visit to view the work being performed under such notice and to confirm that the information
in the notice is correct.
(c) When an emergency is caused by a storm, any work undertaken as an emergency activity
under 310 CMR 10.06(6) must commence within 30 days following the storm event which
caused the agricultural emergency.
(d) Any work undertaken as an emergency activity under 310 CMR 10.06(6) shall be
completed within 30 days from the commencement of such work unless written approval for
a later completion date is given by the Commissioner.
(e) No work under 310 CMR 10.06(6) shall be allowed within estimated habitat which is
indicated on the most recent Estimated Habitat Maps of State-Listed Rare Wetlands Wildlife
published by the Natural Heritage and Endangered Species Program of the Massachusetts
Department of Fisheries, Wildlife, and Environmental Law Enforcement.

(g) Only the following emergency activities are allowed under 310 CMR 10.06(6)(a):
1. The installation of stream bank stabilization measures, provided that:
a. such activity is carried out in accordance with Soil Conservation Service best
management practices;
b. no more than 100 linear feet of bank are altered per storm event, and no more
than 200 linear feet of new rip rap or gabions are placed on the bank of a stream
under this provision cumulatively; and
c. after the 200 foot threshold has been reached the placement of additional rip rap
or gabions following future storm events shall require the filing of a Notice of Intent.
2. The removal of storm debris, including trees, brush, branches, and cobbles, that were
deposited in a stream channel during the storm event, provided that:
a. after the material is removed it is not placed on a bank or in a Bordering
Vegetated Wetland;
b. Soil Conservation Service best management practices are followed; and
c. removal of material from a stream is limited to 100 linear feet per storm event.
Wetland Regulations – May 2008 Page 45
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.06: continued
3. The development of an emergency agricultural water source where the existing
agricultural water source suddenly has been rendered unusable because of contamination,
sudden diversion, or other unforeseen circumstances. Where an emergency agricultural
water supply is required:
a. the work shall be conducted so that impacts to Bordering Vegetated Wetland are
minimized and all impacts, including excavation, access, and any other alterations
to Bordering Vegetated Wetland, shall not exceed 2,000 square feet;
b. the size of the water supply shall be limited to that necessary to provide the
amount of water required to abate the emergency, but not to exceed 2,000 square feet;
c. a Notice of Intent shall be filed if the agricultural water supply is to be used for
more than 60 days, in which case the agricultural water supply shall comply withexisting performance standards under 310 CMR 10.53(3)(a), (b), and (g); and
d. all work shall comply with the Water Management Act, M.G.L. c. 21G.
(7) Notwithstanding any other requirement of 310 CMR 10.06, Immediate Response Actionsreceiving oral approval from the Bureau of Waste Site Cleanup (BWSC) of the Department of
Environmental Protection pursuant to 310 CMR 40.0420(2), or initiated up to 24 hours prior tonotification to and oral approval by BWSC pursuant to 310 CMR 40.0420(7) and (8), may
commence before requesting the conservation commission to issue an emergency certification
under 310 CMR 10.06, so long as such request is made within 24 hours after BWSC has orally
approved commencement of the Immediate Response Action. Once a request for emergency
certification has been made pursuant to 310 CMR 10.06(7), work that commenced before such
filing may continue pending a decision on the request by the conservation commission. Such
work may also continue pending a decision on a request for Departmental review unless the
request has not been filed with the Department within one business day of: issuance by the
conservation commission of the emergency certification; denial by a conservation commission
of the emergency certification; or failure by a conservation commission to act within 24 hours
of a request for emergency certification.
10.07: Compliance with the M.G.L. c. 30, §§ 61 through 62H
(1) The Massachusetts Environmental Policy Act, M.G.L. c. 30, §§ 61 through 62H, may
require an applicant to file an Environmental Notification Form (ENF) and possibly an
Environmental Impact Report (EIR) for the proposed work, prior to the Department's issuance
of a Superseding Order. See 301 CMR 11.00: MEPA Regulations.
(2) If said filing is required, the Department shall so notify the applicant upon receipt of the
request for the Department to act. If within 70 days of the request for the Department to act the
applicant has not filed an ENF, the Department may issue a Superseding Order prohibiting the
project; provided, however, that such an order shall not issue if the Executive Office of
Environmental Affairs determines that the filing of an ENF is not required.
(3) In determining total surface area for purposes of the M.G.L. c. 30, §§ 6 through 62H
wetlands threshold set forth in 301 CMR 11.25(2) and 11.26(7)(a), only those portions of the
Areas Subject to Protection Under M.G.L. c. 131, § 40 specified in 310 CMR 10.02(1), not
including the Buffer Zone, which will be removed, filled, dredged or altered shall be considered.
10.08: Enforcement Orders
(1) When the conservation commission, the Department or the Office of Law Enforcement of
the Executive Office of Environmental Affairs determines that an activity is in violation of
M.G.L. c. 131, § 40, 310 CMR 10.00 or a Final Order, the conservation commission, Department
or the Office of Law Enforcement may issue an Enforcement Order. Violations include:
(a) failure to comply with a Final Order or Final Determination, such as failure to observe
a particular condition or time period specified in the Order;

10.21: Introduction
310 CMR 10.21 through 10.37 apply to all work subject to M.G.L. c. 131, § 40, M.G.L.c. 131, § 40, which will alter, dredge, fill, or remove any coastal beach, coastal dune, tidal flat,
coastal wetland, land subject to coastal storm flowage, coastal bank, land subject to tidal action,or land under an estuary, under a salt pond, under the ocean or under certain streams, ponds,
rivers, lakes or creeks within the coastal zone that are anadromous/catadromous fish runs. This
Part is in addition to and does not change the provisions set forth in 310 CMR 10.01 through
10.10. 310 CMR 10.21 through 10.37 are intended to ensure that development along the
coastline is located, designed, built and maintained in a manner that protects the public interests
in the coastal resources listed in M.G.L. c. 131, § 40. The proponent of the work must submit
sufficient information to enable the issuing authority to determine whether the proposed work
will comply with 310 CMR 10.21 through 10.37. Any proposed work may be subject to the
requirements of sections concerning coastal beaches, coastal dunes and land containing shellfish.
Thus, in order to determine which provisions apply to a proposed project, 310 CMR 10.00 must
be read in its entirety. 310 CMR 10.21 through 10.37 are divided into 16 sections, 44 of which
deal with specific coastal resources. Each coastal resource section begins with a preamble. In
addition, the requirements for protection of the riverfront area in 310 CMR 10.58 apply within
the coastal resource areas. The riverfront area may overlap other coastal resource areas and the
performance standards for each resource area must be met. 310 CMR 10.24(7) applies to
riverfront areas within coastal resource areas. The Preamble identifies the interests of M.G.L.
c. 131, § 40 to which that resource is or is likely to be significant and describes the characteristics
or factors of the resource which are critical to the protection of the interest to which the resource
is significant. 310 CMR 10.21 through 10.37 are in the form of performance standards and shall
be interpreted to protect those characteristics and resources to the maximum extent permissible
under M.G.L. c. 131, § 40.
The performance standards are intended to identify the level of protection the issuing
authority must impose in order to contribute to the protection of the interests of M.G.L. c. 131,
§ 40. It is the responsibility of the issuing authority to order specific measures and requirements
for each proposed project which will ensure that the project is designed and carried out consistent
with the required level of protection. Such authority must then issue an Order of Conditions
which is understandable and enforceable.
10.22: Purpose
310 CMR 10.27 through 10.37 are promulgated pursuant to M.G.L. c. 131, § 40 and are
intended to implement it. They are further intended to establish criteria and standards for the
uniform and coordinated administration of the provisions of M.G.L. c. 131, § 40; to ensure
coordination between the Department and other EOEA agencies; and to ensure consideration by
the Department of relevant policies, laws or programs of other EOEA agencies. 310 CMR 10.21
through 10.37 is, in addition, intended to be consistent with and form a part of the
Commonwealth's Coastal Zone Management Program as it has been promulgated and defined
by 301 CMR 21.00. 310 CMR 10.21 through 10.37, however, are adopted independently under
M.G.L. c. 131, § 40 and would remain in full force and effect in the absence of 301 CMR 21.00.
Wetland Regulations – May 2008 Page 49
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.22: continued
The interpretation and application of 310 CMR 10.21 through 10.37 shall be consistent with
the policies of 301 CMR 21.00 to the maximum extent permissible under M.G.L. c. 131, § 40.
301 CMR 20.99 establishes the CZM policies as part of 301 CMR 20.00, and the Department
recognizes these policies as state environmental policy, which it will carry out in accordance with
M.G.L. c. 21A, § 2. Specifically, 301 CMR 20.99, Policies 1, 2, 3, 4, 5, 6, 9 and 10 are
applicable to the administration of M.G.L. c. 21A, § 2, but the provisions of the more specific
regulations contained in the following sections shall govern, unless the Secretary, pursuant to the
conflict resolution procedures of M.G.L. c. 21A, 301 CMR 21.00 of the CZM Regulations, has
resolved any conflict and has determined that the CZM policies should or should not apply.
10.23: Additional Definitions for 310 CMR 10.21 through 10.35
The definitions contained in 310 CMR 10.23 apply to and are valid for 310 CMR 10.21through 10.37. The following definitions are for terms used throughout 310 CMR 10.21 through10.37. Other terms that are used only in specific sections of 310 CMR 10.21 through 10.37 aredefined in those sections.

10.24: General Provisions
(1) If the issuing authority determines that a resource area is significant to an interest identified
in M.G.L. c. 131, § 40 for which no presumption is stated in the Preamble to the applicable
section, the issuing authority shall impose such conditions as are necessary to contribute to the
protection of such interests. For work in the buffer zone subject to review under 310 CMR
10.02(2)(b)3., the issuing authority shall impose conditions to protect the interests of the Act
identified for the adjacent resource area. The potential for adverse impacts to resource areas
from work in the buffer zone may increase with the extent of the work and the proximity to the
resource area. The issuing authority may consider the characteristics of the buffer zone, such as
Wetland Regulations – May 2008 Page 51
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.24: continued
the presence of steep slopes, that may increase the potential for adverse impacts on resource
areas. Conditions may include limitations on the scope and location of work in the buffer zone
as necessary to avoid alteration of resource areas. The issuing authority may require erosion and
sedimentation controls during construction, a clear limit of work, and the preservation of natural
vegetation adjacent to the resource area and/or other measures commensurate with the scope and
location of the work within the buffer zone to protect the interests of the Act. Where a buffer
zone has already been developed, the issuing authority may consider the extent of existing
development in its review of subsequent proposed work and, where prior development is
extensive, may consider measures such as the restoration of natural vegetation adjacent to the
resource area to protect the interests of the Act. The purpose of preconstruction review of work
in the buffer zone is to ensure that adjacent resource areas are not adversely affected during orafter completion of the work.
(2) When the issuing authority determines that a project in one resource area would adverselyaffect another resource area, the issuing authority shall impose such conditions as will protectthe interest to which each resource are significant to the same degree as required in 310 CMR
10.00 concerning each resource area.
(3) A determination which finds that a resource area is not significant to an interest to which
it is presumed in 310 CMR 10.21 through 10.37 to be significant, or is significant to an interest
to which it is presumed to be not significant, shall be made on Form 7. No such determination
shall be effective unless a copy of this form and the accompanying written explanation for the
determination required by 310 CMR 10.00 is sent on the day of issuance to the appropriate
regional office of the Department.
(4) (a) 310 CMR 10.21 through 10.37 do not change the requirement of any other
Massachusetts statute or by-law. A proposed project must comply with all applicable
requirements of other federal, state and local statutes and by-laws, in addition to meeting the
requirements of 310 CMR 10.00. Examples of such laws which may be applicable are the
Coastal Restrictions Act (M.G.L. c. 130, § 105), the Ocean Sanctuaries Act (M.G.L. c. 132A,
§§ 13 through 16 and 18), the Mineral Resources Act (M.G.L. c. 21, §§ 54 through 58), the
Massachusetts Clean Water Act (M.G.L. c. 21, §§ 26 through 53), the Waterways laws
(M.G.L. c. 91), the Massachusetts Environmental Policy Act (M.G.L. c. 30, §§ 61 through
62H), the act establishing the Martha's Vineyard Commission (St. 1974, c. 637) and the
Scenic Rivers Act (M.G.L. c. 21, § 2. 17B).
(b) When the site of a proposed project is subject to a Restriction Order which has been
duly recorded under the provisions of M.G.L. c. 130, § 105, such a project shall conform to
310 CMR 10.21 through 10.37.
(c) If an NPDES permit for any new point-source discharge has or will be obtained prior
to the commencement of the discharge, the effluent limitations established in such permit
shall be deemed to satisfy the water quality standards established in any section of 310 CMR
10.21 through 10.37 relative to the effects of the new point-source discharge on water
quality. Such effluent limitations shall be incorporated or shall be deemed to be incorporated
into the Order of Conditions.
(5) (a) When any area subject to 310 CMR 10.21 through 10.37 has been designated an Area
of Critical Environmental Concern by the Secretary of Environmental Affairs pursuant to
301 CMR 21.00, and when the Secretary has made a finding of the significance of the area
to one or more interests of M.G.L. c. 131, § 40, the issuing authority shall presume that such
area is significant to those interests.
(b) When any portion of a designated Area of Critical Environmental Concern is determined
by the issuing authority to be significant to any of the interests of M.G.L. c. 131, § 40, any
proposed project in or impacting that portion of the Area of Critical Environmental Concern
shall have no adverse effect upon those interests, except as provided under 310 CMR
10.25(4) for maintenance dredging.

(6) Where any section of 310 CMR 10.00 provides that a proposed project "may be permitted"
in certain circumstances, no such project shall be undertaken until all of the usual procedures
required by M.G.L. c. 131, § 40 and 310 CMR 10.21 through 10.37 have been followed and a
Final Order has been issued for the work. The issuing authority shall impose such conditions on
such projects as may be necessary to contribute to the protection of the interests of M.G.L.
c. 131, § 40.
(7) 310 CMR 10.24 is not intended to prohibit the issuing authority from imposing such
additional conditions as are necessary to contribute to the interests of M.G.L. c. 131, § 40 where
the indicated minimizing measures are not sufficient.
(a) Notwithstanding any provisions of 310 CMR 10.25 through 10.35, whenever an area inwhich a project is proposed is found to be significant to one or more of the interests of
M.G.L. c. 131, § 40, the construction, reconstruction, operation and maintenance of thefollowing structures associated with and essential to an electric generating facility may bepermitted as provided herein (although no such project may be permitted which will have anyadverse effect on specified habitat sites of rare vertebrate or invertebrate species, as identified

10. the provisions of 310 CMR 10.24(7)(b) shall also apply when applicable.
(b) Notwithstanding any provisions of 310 CMR 10.25 through 10.35, whenever an area in
which a project is proposed is found to be significant to one or more of the interests of
M.G.L. c. 131, § 40, the construction, reconstruction, operation and maintenance of
underground and overhead public utilities, limited to electrical distribution or transmission
lines, or communication, sewer, water and natural gas lines, may be permitted, (although no
such project may be permitted which will have any adverse effect on specified habitat sites
of rare vertebrate or invertebrate species, as identified by procedures established under
310 CMR 10.37) provided:

be restored substantially to its original condition by immediately transplanting
appropriate marsh plant nursery stock once construction is completed. Baffles ofconcrete, clay or other non-porous material shall be placed in the trench, if necessary, to
prevent groundwater excursion. During the first growing season, periodic maintenanceof the marsh restoration area shall be required and shall include at least the replacementof non-surviving transplants and the removal of all deposits of debris and organic litter.During construction, equipment such as Bailey-bridges and helicopters shall be used tominimize, using best available measures, the adverse effects of construction on the saltmarsh. All vehicles shall be used only on swamp mats or in such a way as to prevent tire
marks, trenches, or ruts;5. no utility shall traverse a salt marsh unless the applicant has shown that any thermal
influence on the salt marsh of such line subsequent to the project being completed will
not alter the natural freezing and thawing patterns of the top 24 inches of the salt marsh
surface. Thermal sand, concrete or other suitable material may be used to backfill the
trench to a point no less than 24 inches below grade. Above this level, clean sand shall
be used to restore the level of the trench to that of the surrounding undisturbed salt
marsh;

10.25: Land Under the Ocean
(1) Preamble. Land under the ocean is likely to be significant to the protection of marine
fisheries and, where there are shellfish, to protection of land containing shellfish. Nearshore*
areas of land under the ocean are likely to be significant to storm damage prevention, flood
control, and protection of wildlife habitat.
Land under the ocean provides feeding areas, spawning and nursery grounds and shelter for
many coastal organisms related to marine fisheries. Nearshore areas of land under the ocean helpreduce storm damage and flooding by diminishing and buffering the high energy effects of
storms. Submerged bars dissipate storm wave energy. Such areas provide a source of sedimentfor seasonal rebuilding of coastal beaches and dunes. Nearshore areas of land under the oceanalso provide important food for birds. For example, waterfowl feed heavily on vegetation (suchas eel grass, widgeon grass, and macrophytic algae) and invertebrates (such as polychaetes andmollusks) found in estuaries and other shallow submerged land under the ocean.When a proposed project involves the dredging, removing, filling or altering of a nearshore
area of land under the ocean, the issuing authority shall presume that the area is significant to theinterests specified above.
When a proposed project involves the dredging, removing, filling or altering of land under
the ocean beyond the nearshore area, the issuing authority shall presume that such land is
significant to the protection of marine fisheries and, where there are shellfish, to the protection
of land containing shellfish and that it is not significant to storm damage prevention, flood
control or protection of wildlife habitat.
These presumptions may be overcome only upon a clear showing that the area or land does
not play a role in the protection of marine fisheries or wildlife habitat, land containing shellfish,
storm damage prevention or flood control, as appropriate, and if the issuing authority makes a
written determination to such effect.
When land under the ocean underlies an anadromous/catadromous fish run, 310 CMR
10.35(1) through 10.35(4) shall apply. When land under the ocean is in a designated port area,
310 CMR 10.26(1) through 10.26(4) shall apply. When land under the ocean is land containing
shellfish, 310 CMR 10.34(1) through 10.34(7) shall apply.
When nearshore areas of land under the ocean are significant to storm damage prevention or
flood control, the bottom topography of such land is critical to the protection of those interests.
When nearshore areas or other land under the ocean is significant to the protection of marine
fisheries or wildlife habitat, the following factors are critical to the protection of such interests:
(a) water circulation,
(b) distribution of sediment grain size,
(c) water quality,
(d) finfish habitat, and
(e) important food for wildlife.
(2) Definitions.
Land Under the Ocean means land extending from the mean low water line seaward to the
boundary of the municipality's jurisdiction and includes land under estuaries.
For regulations concerning land containing shellfish, see 310 CMR 10.34.*
Wetland Regulations – May 2008 Page 58
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.25: continued
Nearshore Areas of land under the ocean means that land extending from the mean low water
line to the seaward limit of a municipality's jurisdiction, but in no case beyond the point where
the land is 80 feet below the level of the ocean at mean low water. However, the nearshore area
shall extend seaward only to that point where the land is 30 feet below the level of the ocean at
mean low water for municipalities bordering Buzzard's Bay and Vineyard Sound (west of a line
between West Chop, Martha's Vineyard and Nobska Point, Falmouth), 40 feet below the level
of the ocean at mean low water for Provincetown's land in Cape Cod Bay, and 50 feet below the
level of the ocean at mean low water for Truro's and Wellfleet's land in Cape Cod Bay.
WHEN LAND UNDER THE OCEAN OR NEARSHORE AREAS OF LAND UNDER THE
OCEAN ARE FOUND TO BE SIGNIFICANT TO THE PROTECTION OF MARINEFISHERIES, PROTECTION OF WILDLIFE HABITAT, STORM DAMAGE PREVENTION
OR FLOOD CONTROL, 310 CMR 10.25(3) through (7) SHALL APPLY:
(3) Improvement dredging for navigational purposes affecting land under the ocean shall bedesigned and carried out using the best available measures so as to minimize adverse effects on
such interests caused by changes in:(a) bottom topography which will result in increased flooding or erosion caused by an
increase in the height or velocity of waves impacting the shore;
(b) sediment transport processes which will increase flood or erosion hazards by affecting
the natural replenishment of beaches;
(c) water circulation which will result in an adverse change in flushing rate, temperature,
or turbidity levels; or
(d) marine productivity which will result from the suspension or transport of pollutants, the
smothering of bottom organisms, the accumulation of pollutants by organisms, or the
destruction of marine fisheries habitat or wildlife habitat.
(4) Maintenance dredging for navigational purposes affecting land under the ocean shall be
designed and carried out using the best available measures so as to minimize adverse effects on
such interests caused by changes in marine productivity which will result from the suspension
or transport of pollutants, increases in turbidity, the smothering of bottom organisms, the
accumulation of pollutants by organisms, or the destruction of marine fisheries habitat or wildlife
habitat.
(5) Projects not included in 310 CMR 10.25(3) or 10.25(4) which affect nearshore areas of land
under the ocean shall not cause adverse effects by altering the bottom topography so as to
increase storm damage or erosion of coastal beaches, coastal banks, coastal dunes, or salt
marshes.
(6) Projects not included in 310 CMR 10.25(3) which affect land under the ocean shall if
water-dependent be designed and constructed, using best available measures, so as to minimize
adverse effects, and if non-water-dependent, have no adverse effects, on marine fisheries habitat
or wildlife habitat caused by:
(a) alterations in water circulation;

10.26: Designated Port Areas
(1) Preamble. Land under the ocean in designated port areas is likely to be significant to marine
fisheries, storm damage prevention and flood control. In designated port areas, salt marshes,
coastal dunes, land under salt ponds, coastal beaches, tidal flats, barrier beaches, rocky intertidal
shores and land containing shellfish are not likely to be significant to marine fisheries, storm
damage prevention or flood control.
Many species of marine fisheries, including anadromous fish, may inhabit port areas.
Anadromous fish may need to be able to pass through port areas to inland spawning areas or to
the sea. Other species frequently feed in designated port areas due to high nutrient
concentrations in the waters and the tidelands.
Designated port areas, which are portions of developed harbors, are usually located in
estuaries. Relatively high concentrations of contaminants, from vessel discharges and point andnon-point source discharges, are likely to occur in port areas. Water circulation patterns tend to
distribute pollution throughout the estuary, and to other areas which are likely to be significantto other interests of M.G.L. c. 131, § 40. Land forms in designated port areas have been greatlyaltered from their natural shape, and coastal engineering structures often have replaced naturalprotection for upland areas from storm damage and flooding.
Land under the ocean often provides support for such structures. Some proposed activitiesmay alter wave and current patterns so as to affect the stability of such structures or the depths
or configurations of navigation channels.
Where a proposed project involves dredging, filling, removing, or altering land under the
ocean in designated port areas, the issuing authority shall presume that the area is significant to
marine fisheries, storm damage prevention and flood control. These presumptions may be
overcome only upon a clear showing that land under the ocean in designated port areas does not
play a role in the protection of marine fisheries, storm damage prevention or flood control, or that
a salt marsh, coastal dune, land under a salt pond, coastal beach, tidal flat, barrier beach, rocky
intertidal shore or land containing shellfish, in designated port areas, does play a role in marine
fisheries, storm damage prevention or flood control, and if the issuing authority makes a written
determination to such effect.
When a proposed project in a designated port area is on land under the ocean which is
determined to be significant to marine fisheries, the following factors are critical to the protection
of such interests:
(a) water circulation, and
(b) water quality.
When a proposed project in a designated port area is on land under the ocean which is
determined to be significant to storm damage prevention or flood control, the ability of such land
to provide support for adjacent coastal or man-made structures is critical to the protection of such
interests.
(2) Definition. Designated Port Areas means those areas designated in 301 CMR 25.00 of the
Coastal Zone Management Regulations.
WHEN LAND UNDER THE OCEAN IN DESIGNATED PORT AREAS IS FOUND TO
BE SIGNIFICANT TO THE PROTECTION OF MARINE FISHERIES, STORM DAMAGE
PREVENTION OR FLOOD CONTROL, 310 CMR 10.26(3) and (4) SHALL APPLY:
(3) Projects shall be designed and constructed, using best practical measures, so as to minimize
adverse effects on marine fisheries caused by changes in:
(a) water circulation;
(b) water quality, including, but not limited to, other than natural fluctuations in the level
of dissolved oxygen, temperature or turbidity, or the addition of pollutants.
(4) Projects shall be designed and constructed, using the best practical measures, so as to
minimize, adverse effects on storm damage prevention or flood control caused by changes in
such land's ability to provide support for adjacent coastal banks or adjacent coastal engineering
structures.

10.27: Coastal Beaches
(1) Preamble. Coastal beaches, which are defined to include tidal flats, are significant to storm
damage prevention, flood control and the protection of wildlife habitat. In addition, tidal flats
are likely to be significant to the protection of marine fisheries and where there are shellfish, to
land containing shellfish.*
Coastal beaches dissipate wave energy by their gentle slope, their permeability and their
granular nature, which permit changes in beach form in response to changes in wave conditions.
Coastal beaches serve as a sediment source for dunes and subtidal areas. Steep storm waves
cause beach sediment to move offshore, resulting in a gentler beach slope and greater energy
dissipation. Less steep waves cause an onshore return of beach sediment, where it will be
available to provide protection against future storm waves.
A coastal beach at any point serves as a sediment source for coastal areas downdrift from thatpoint. The oblique approach of waves moves beach sediment alongshore in the general direction
of wave action. Thus, the coastal beach is a body of sediment which is moving along the shore.Coastal beaches serve the purposes of storm damage prevention and flood control bydissipating wave energy, by reducing the height of storm waves, and by providing sediment tosupply other coastal features, including coastal dunes, land under the ocean and other coastal
beaches. Interruptions of these natural processes by man-made structures reduce the ability ofthe coastal beach to perform these functions.
A number of birds also nest in the coastal berm, between the toe of a dune and the high tide
line. In addition, isolated coastal beaches on small islands are important as haul out areas for
harbor seals.
Tidal flats are likely to be significant to the protection of marine fisheries and wildlife habitat
because they provide habitats for marine organisms such as polychaete worms and mollusks,
which in turn are food sources for fisheries and migratory and wintering birds. Coastal beaches
are extremely important in recycling of nutrients derived from storm drift and tidal action.
Vegetative debris along the drift line is vital for resident and migratory shorebirds, which feed
largely on invertebrates which eat the vegetation. Below the drift line in the lower intertidal zone
are infauna (invertebrates such as mollusks and crustacea) which are also eaten by shore birds.
Tidal flats are also sites where organic and inorganic materials may become entrapped and
then returned to the photosynthetic zone of the water column to support algae and other primary
producers of the marine food web.
When a proposed project involves the dredging, filling, removing, or altering of a coastal
beach, the issuing authority shall presume that the coastal beach is significant to the interests
specified above. This presumption may be overcome only upon a clear showing that a coastal
beach does not play a role in storm damage prevention, flood control, or protection of wildlife
habitat, or that tidal flats do not play a role in the protection of marine fisheries or land
containing shellfish, and if the issuing authority makes a written determination to such effect.
When coastal beaches are determined to be significant to storm damage prevention or flood
control, the following characteristics are critical to the protection of those interests:
(a) volume (quantity of sediments) and form, and
(b) the ability to respond to wave action.
When coastal beaches are significant to the protection of marine fisheries or wildlife habitat,
the following characteristics are critical to the protection of those interests:
(a) distribution of sediment grain size,
(b) water circulation
(c) water quality, and
(d) relief and elevation.

10.34(8) shall apply.
(2) Definitions.
Coastal Beach means unconsolidated sediment subject to wave, tidal and coastal storm action
which forms the gently sloping shore of a body of salt water and includes tidal flats. Coastal
beaches extend from the mean low water line landward to the dune line, coastal bankline or the
seaward edge of existing man-made structures, when these structures replace one of the above
lines, whichever is closest to the ocean.
Tidal Flat means any nearly level part of a coastal beach which usually extends from the meanlow water line landward to the more steeply sloping face of the coastal beach or which may beseparated from the beach by land under the ocean.
WHEN A COASTAL BEACH IS DETERMINED TO BE SIGNIFICANT TO STORMDAMAGE PREVENTION, FLOOD CONTROL, OR PROTECTION OF WILDLIFE
HABITAT, 310 CMR 10.27(3) through (7) SHALL APPLY:
(3) Any project on a coastal beach, except any project permitted under 310 CMR 10.30(3)(a),
shall not have an adverse effect by increasing erosion, decreasing the volume or changing the
form of any such coastal beach or an adjacent or downdrift coastal beach.
(4) Any groin, jetty, solid pier, or other such solid fill structure which will interfere with littoral
drift, in addition to complying with 310 CMR 10.27(3), shall be constructed as follows:
(a) It shall be the minimum length and height demonstrated to be necessary to maintain
beach form and volume. In evaluating necessity, coastal engineering, physical oceanographic
and/or coastal geologic information shall be considered.
(b) Immediately after construction any groin shall be filled to entrapment capacity in height
and length with sediment of grain size compatible with that of the adjacent beach.
(c) Jetties trapping littoral drift material shall contain a sand by-pass system to transfer
sediments to the downdrift side of the inlet or shall be periodically redredged to provide
beach nourishment to ensure that downdrift or adjacent beaches are not starved of sediments.
(5) Notwithstanding 310 CMR 10.27(3), beach nourishment with clean sediment of a grain size

effects, on marine fisheries and wildlife habitat caused by:
(a) alterations in water circulation,
(b) alterations in the distribution of sediment grain size, and
(c) changes in water quality, including, but not limited to, other than natural fluctuations in
the levels of dissolved oxygen, temperature or turbidity, or the addition of pollutants.
(7) Notwithstanding the provisions of 310 CMR 10.27(3) through 10.27(6), no project may be
permitted which will have any adverse effect on specified habitat sites or rare vertebrate or
invertebrate species, as identified by procedures established under 310 CMR 10.37.

10.28: Coastal Dunes
(1) Preamble. All coastal dunes are likely to be significant to storm damage prevention and
flood control, and all coastal dunes on barrier beaches and the coastal dune closest to the coastal
beach in any area are per se significant to storm damage prevention and flood control. Coastal
dunes are also often significant to the protection of wildlife habitat.
Coastal dunes aid in storm damage prevention and flood control by supplying sand to coastal
beaches. Coastal dunes protect inland coastal areas from storm damage and flooding by storm
waves and storm elevated sea levels because such dunes are higher than the coastal beaches
which they border. In order to protect this function, coastal dune volume must be maintained
while allowing the coastal dune shape to conform to natural wind and water flow patterns.
Vegetation cover contributes to the growth and stability of coastal dunes by providing
conditions favorable to sand deposition.On retreating shorelines, the ability of the coastal dunes bordering the coastal beach to move
landward at the rate of shoreline retreat allows these dunes to maintain their form and volume,which in turn promotes their function of protecting against storm damage or flooding.A number of birds, most commonly terns and gulls, nest at the base or sides of dunes. Insome dune systems other birds also nest in the interdunal area, the species being determined by
the plant community structure, topography, and hydrologic regime of the area. In a few dunesystems, wet meadows or vernal pool habitats occur, which serve as important feeding areas for
a wide variety of bird species.
When a proposed project involves the dredging, filling, removal or alteration of a coastal
dune, the issuing authority shall presume that the area is significant to the interests of storm
damage prevention, flood control and the protection of wildlife habitat. This presumption may
be overcome only upon a clear showing that a coastal dune does not play a role in storm damage
prevention, flood control or the protection of wildlife habitat, and if the issuing authority makes
a written determination to that effect.
When a coastal dune is significant to storm damage prevention, flood control or the
protection of wildlife habitat, the following characteristics are critical to the protection of those
interest(s):
(a) the ability of the dune to erode in response to coastal beach conditions;
(b) dune volume;
(c) dune form, which must be allowed to be changed by wind and natural water flow;
(d) vegetative cover;
(e) the ability of the dune to move landward or laterally; or
(f) the ability of the dune to continue serving as bird nesting habitat.
(2) Definition. Coastal Dune means any natural hill, mound or ridge of sediment landward of
a coastal beach deposited by wind action or storm overwash. Coastal dune also means sediment
deposited by artificial means and serving the purpose of storm damage prevention or flood
control.
WHEN A COASTAL DUNE IS DETERMINED TO BE SIGNIFICANT TO STORM
DAMAGE PREVENTION, FLOOD CONTROL OR THE PROTECTION OF WILDLIFE
HABITAT, 310 10.28(3) through (6) SHALL APPLY:
(3) Any alteration of, or structure on, a coastal dune or within 100 feet of a coastal dune shall
not have an adverse effect on the coastal dune by:
(a) affecting the ability of waves to remove sand from the dune;
(b) disturbing the vegetative cover so as to destabilize the dune;
(c) causing any modification of the dune form that would increase the potential for storm
or flood damage;
(d) interfering with the landward or lateral movement of the dune;
(e) causing removal of sand from the dune artificially; or
(f) interfering with mapped or otherwise identified bird nesting habitat.

10.28: continued
(4) Notwithstanding the provisions of 310 CMR 10.28(3), when a building already exists upon
a coastal dune, a project accessory to the existing building may be permitted, provided that such
work, using the best commercially available measures, minimizes the adverse effect on the
coastal dune caused by the impacts listed in 310 CMR 10.28 (3)(b) through 10.28(3)(e). Such
an accessory project may include, but is not limited to, a small shed or a small parking area for
residences. It shall not include coastal engineering structures.
(5): The following projects may be permitted, provided that they adhere to the provisions of
310 CMR 10.28(3):
(a) pedestrian walkways, designed to minimize the disturbance to the vegetative cover and
traditional bird nesting habitat;(b) fencing and other devices designed to increase dune development; and
(c) plantings compatible with the natural vegetative cover.
(6) Notwithstanding the provisions of 310 CMR 10.28(3) through (5), no project may bepermitted which will have any adverse effect on specified habitat sites of rare vertebrate or
invertebrate species, as identified by procedures established under 310 CMR 10.37.
10.29: Barrier Beaches
(1) Preamble. Barrier beaches are significant to storm damage prevention and flood control and
are likely to be significant to the protection of marine fisheries and wildlife habitat and, where
there are shellfish, the protection of land containing shellfish.*
Barrier beaches protect landward areas because they provide a buffer to storm waves and to
sea levels elevated by storms. Barrier beaches protect from wave action such highly productive
wetlands as salt marshes, estuaries, lagoons, salt ponds and fresh water marshes and ponds,
which are in turn important to marine fisheries and protection of wildlife habitat. Barrier
beaches and the dunes thereon are also important to the protection of wildlife habitat in the ways
described in 310 CMR 10.27(1) (coastal beaches) and 10.28(1) (coastal dunes).
Barrier beaches are maintained by the alongshore movement of beach sediment caused by
wave action. The coastal dunes and tidal flats on a barrier beach consist of sediment supplied
by wind action, storm wave overwash and tidal inlet deposition. Barrier beaches in
Massachusetts undergo a landward migration caused by the landward movement of sediment by
wind, storm wave overwash and tidal current processes. The continuation of these processes
maintains the volume of the landform which is necessary to carry out the storm and flood buffer
function.
When a proposed project involves removal, filling, dredging or altering of a barrier beach,
the issuing authority shall presume that the barrier beach, including all of its coastal dunes, is
significant to the interest(s) specified above. This presumption may be overcome only upon a
clear showing that a barrier beach, including all of its coastal dunes, does not play a role in storm
damage prevention, flood control, or the protection of marine fisheries, wildlife habitat, or land
containing shellfish, and if the issuing authority makes a written determination to such effect.
When a barrier beach is significant to storm damage prevention and flood control, the
characteristics of coastal beaches, tidal flats and coastal dunes listed in 310 CMR 10.27(1) and
10.28(1) and their ability to respond to wave action, including storm overwash sediment
transport, are critical to the protection of the interests specified in 310 CMR 10.29.
(2) Definition. Barrier Beach means a narrow low-lying strip of land generally consisting of
coastal beaches and coastal dunes extending roughly parallel to the trend of the coast. It is
separated from the mainland by a narrow body of fresh, brackish or saline water or a marsh
system. A barrier beach may be joined to the mainland at one or both ends.

(3) When a Barrier Beach is Determined to be Significant to Storm Damage Prevention, Flood
Control, Marine Fisheries or Protection of Wildlife Habitat. 310 CMR 10.27(3) through
10.27(6) (coastal beaches) and 10.28(3) through 10.28(5) (coastal dunes) shall apply to the
coastal beaches and to all coastal dunes which make up a barrier beach.
(4) Notwithstanding the provisions of 310 CMR 10.29(3), no project may be permitted which
will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate species,
as identified by procedures established under 310 CMR 10.37.
10.30: Coastal Banks
(1) Preamble. Coastal banks are likely to be significant to storm damage prevention and flood
control. Coastal banks that supply sediment to coastal beaches, coastal dunes and barrier beachesare per se significant to storm damage prevention and flood control. Coastal banks that, becauseof their height, provide a buffer to upland areas from storm waters are significant to stormdamage prevention and flood control.Coastal banks composed of unconsolidated sediment and exposed to vigorous wave actionserve as a major continous source of sediment for beaches, dunes, and barrier beaches (as well
as other land forms caused by coastal processes). The supply of sediment is removed from banksby wave action, and this removal takes place in response to beach and sea conditions. It is a
naturally occurring process necessary to the continued existence of coastal beaches, coastal dunes
and barrier beaches which, in turn, dissipate storm wave energy, thus protecting structures of
coastal wetlands landward of them from storm damage and flooding.
Coastal banks, because of their height and stability, may act as a buffer or natural wall, which
protects upland areas from storm damage and flooding. While erosion caused by wave action
is an integral part of shoreline processes and furnishes important sediment to downdrift
landforms, erosion of a coastal bank by wind and rain runoff, which plays only a minor role in
beach nourishment, should not be increased unnecessarily. Therefore, disturbances to a coastal
bank which reduce its natural resistance to wind and rain erosion cause cuts and gullys in the
bank, increase the risk of its collapse, increase the danger to structures at the top of the bank and
decrease its value as a buffer.
Bank vegetation tends to stabilize the bank and reduce the rate of erosion due to wind and
rain runoff. Pedestrian and vehicular traffic damages the protective vegetation and frequently
leads to gully erosion or deep "blowouts" on unconsolidated banks. Therefore, any project
permitted by 310 CMR 10.30 should incorporate, when appropriate, elevated walkways.
A particular coastal bank may serve both as a sediment source and as a buffer, or it may serve
only one role.
When a proposed project involves dredging, removing, filling, or altering a coastal bank, the
issuing authority shall presume that the area is significant to storm damage prevention and flood
control. This presumption may be overcome only upon a clear showing that a coastal bank does
not play a role in storm damage prevention or flood control, and if the issuing authority makes
a written determination to that effect.
When issuing authority determines that a coastal bank is significant to storm damage
prevention or flood control because it supplies sediment to coastal beaches, coastal dunes or
barrier beaches, the ability of the coastal bank to erode in response to wave action is critical to
the protection of that interest(s).
When the issuing authority determines that a coastal bank is significant to storm damage
prevention or flood control because it is a vertical buffer to storm waters, the stability of the
bank, i.e., the natural resistance of the bank to erosion caused by wind and rain runoff, is critical
to the protection of that interest(s).
(2) Definition. Coastal Bank means the seaward face or side of any elevated landform, other
than a coastal dune, which lies at the landward edge of a coastal beach, land subject to tidal
action, or other wetland.

tidal action.
(5) The Order of Conditions and the Certificate of Compliance for any new building within 100

permitted which will have any adverse effect on specified habitat sites of rare vertebrate or
invertebrate species, as identified by procedures established under 310 CMR 10.37.
10.31: Rocky Intertidal Shores
(1) Preamble. Rocky intertidal shores are likely to be significant to storm damage prevention,
flood control, protection of marine fisheries and wildlife habitat and where there are shellfish,
protection of land containing shellfish.*
Rocky shore environments are habitats for macroalgae and marine invertebrates and provide
protection to and food for, larger marine organisms such as crabs, lobsters, and such fish species
as winter flounder, as well as a number of birds. Most marine plants and animals found in rocky
shore environments are uniquely adapted to survive there and cannot survive elsewhere. Harbor
seals also use rocky intertidal shores, such as rock outcroppings or isolated shores of small
islands, as haul out areas.

When a proposed project involves the filling, removing or altering of a rocky intertidal shore,
the issuing authority shall presume that such shore is significant to the interests specified above.
This presumption may be overcome only upon a clear showing that a rocky intertidal shore does
not play a role in storm damage prevention, flood control, protection of marine fisheries or
wildlife habitat, and where there are shellfish, protection of land containing shellfish and if the
issuing authority makes a written determination to such effect.*
When a rocky intertidal shore is determined to be significant to storm damage prevention,
flood control, or protection of wildlife habitat the form and volume of exposed intertidal bedrock
and boulders are critical to the protection of those interests.
When a rocky intertidal shore is significant to the protection of marine fisheries or wildlife
habitat, water circulation and water quality are critical to the protection of those interests.
(2) Definition. Rocky Intertidal Shores means naturally occurring rocky areas, such as bedrockor boulder-strewn areas between the mean high water line and the mean low water line.
(3) When a Rocky Intertidal Shore is Determined to be Significant to Storm Damage
Prevention, Flood Control, or Protection of Wildlife Habitat, any proposed project shall bedesigned and constructed, using the best practical measures, so as to minimize adverse effects

(4) When a Rocky Intertidal Shore is Determined to be Significant to the Protection of Marine
Fisheries or Wildlife Habitat, any proposed project shall if water-dependent be designed and

non-water-dependent, have no adverse effects, on water circulation and water quality. Water
quality impacts include, but are not limited to, other than natural fluctuations in the levels of
dissolved oxygen, temperature or turbidity, or the addition of pollutants.
(5) Notwithstanding the provisions of 310 CMR 10.31(3) and (4), no project may be permitted
which will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate
species, as identified by procedures established under 310 CMR 10.37.
10.32: Salt Marshes
(1) Preamble. Salt marshes are significant to protection of marine fisheries, wildlife habitat,
and where there are shellfish, to protection of land containing shellfish, and prevention of
pollution and are likely to be significant to storm damage prevention and ground water supply.
A salt marsh produces large amounts of organic matter. A significant portion of this material
is exported as detritus and dissolved organics to estuarine and coastal waters, where it provides
the basis for a large food web that supports many marine organisms, including finfish and
shellfish as well as many bird species. Salt marshes also provide a spawning and nursery habitat
for several important estuarine forage finfish as well as important food, shelter, breeding areas,
and migratory and overwintering areas for many wildlife species.
Salt marsh plants and substrate remove pollutants from surrounding waters. The network of
salt marsh vegetation roots and rhizomes binds sediments together.
The sediments absorb chlorinated hydrocarbons and heavy metals such as lead, copper, and
iron. The marsh also retains nitrogen and phosphorous compounds, which in large amounts can
lead to algal blooms in coastal waters.
The underlying peat also serves as a barrier between fresh ground water landward of the salt
marsh and the ocean, thus helping to maintain the level of such ground water.
Salt marsh cord grass and underlying peat are resistant to erosion and dissipate wave energy,
thereby providing a buffer that reduces wave damage.

When a proposed project involves the dredging, filling, removing or altering of a salt marsh,
the issuing authority shall presume that such area is significant to the interests specified above.
This presumption may be overcome only upon a clear showing that a salt marsh does not play
a role in the protection of marine fisheries or wildlife habitat, prevention of pollution, ground
water supply, or storm damage prevention, and if the issuing authority makes a written
determination to such effect.
When a salt marsh is significant to one or more of the interests specified above, the following
characteristics are critical to the protection of such interest(s):
(a) the growth, composition and distribution of salt marsh vegetation, (protection of marine
fisheries and wildlife habitat, prevention of pollution, storm damage prevention);
(b) the flow and level of tidal and fresh water (protection of marine fisheries and wildlifehabitat, prevention of pollution); and
(c) the presence and depth of peat (ground water supply, prevention of pollution, stormdamage prevention).
(2) Definitions.
Salt Marsh means a coastal wetland that extends landward up to the highest high tide line, that
is, the highest spring tide of the year, and is characterized by plants that are well adapted to orprefer living in, saline soils. Dominant plants within salt marshes are salt meadow cord grass
(Spartina patens) and/or salt marsh cord grass (Spartina alterniflora). A salt marsh may contain
tidal creeks, ditches and pools.
Spring Tide means the tide of the greatest amplitude during the approximately 14-day tidal cycle.
It occurs at or near the time when the gravitational forces of the sun and the moon are in phase
(new and full moons).
WHEN A SALT MARSH IS DETERMINED TO BE SIGNIFICANT TO THE
PROTECTION OF MARINE FISHERIES, THE PREVENTION OF POLLUTION, STORM
DAMAGE PREVENTION OR GROUND WATER SUPPLY, 310 CMR 10.32(3) through (6)
SHALL APPLY:

water adjacent to a salt marsh shall not destroy any portion of the salt marsh and shall not have
an adverse effect on the productivity of the salt marsh. Alterations in growth, distribution and
composition of salt marsh vegetation shall be considered in evaluating adverse effects on
productivity. This section shall not be construed to prohibit the harvesting of salt hay.
(4) Notwithstanding the provisions of 310 CMR 10.32(3), a small project within a salt marsh,
such as an elevated walkway or other structure which has no adverse effects other than blocking
sunlight from the underlying vegetation for a portion of each day, may be permitted if such a
project complies with all other applicable requirements of 310 CMR 10.21 through 10.37.
(5) Notwithstanding the provisions of 310 CMR 10.32(3), a project which will restore or
rehabilitate a salt marsh, or create a salt marsh, may be permitted.
(6) Notwithstanding the provisions of 310 CMR 10.32(3) through (5), no project may be
permitted which will have any adverse effect on specified habitat sites of rare vertebrate or
invertebrate species, as identified by procedures established under 310 CMR 10.37.
10.33: Land Under Salt Ponds
(1) Preamble. Land under salt ponds is significant to the protection of marine fisheries and
wildlife habitat and, where there are shellfish, to the protection of land containing shellfish.*
For regulations concerning land containing shellfish, see 310 CMR 10.34.*
Wetland Regulations – May 2008 Page 68
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.33: continued
Land under salt ponds provides an excellent habitat for marine fisheries. The high
productivity of plants in salt ponds provides food for shellfish, crustaceans and larval and
juvenile fish. Salt ponds also provide spawning areas for shellfish and are nursery areas for crabs
and fish. In addition to the many birds which feed on fish found in salt ponds, waterfowl also
eat invertebrates such as mollusks and crustaceans, which in turn depend on bottom sediment
and vegetation. Some bird species also eat rupia and eel grass which may be rooted in land under
salt ponds.
When a proposed project involves the dredging, filling, removing or altering of land under
a salt pond, the issuing authority shall presume that such land is significant to the protection of
marine fisheries and wildlife habitat and, where there are shellfish, to the protection of land
containing shellfish. This presumption may be overcome only upon a clear showing that landunder a salt pond does not play a role in the protection of marine fisheries or wildlife habitat or
land containing shellfish, and if the issuing authority makes a written determination to sucheffect.When land under a salt pond is significant to the protection of marine fisheries or wildlifehabitat, the following factors are critical to the protection of that interest:(a) water circulation,(b) distribution of sediment grain size,
(c) freshwater inflow,(d) productivity of plants, and
(e) water quality.
(2) Definition. Salt Pond means a shallow enclosed or semi-enclosed body of saline water that
may be partially or totally restricted by barrier beach formation. Salt ponds may receive
freshwater from small streams emptying into their upper reaches and/or springs in the salt pond
itself.
WHEN LAND UNDER A SALT POND IS DETERMINED TO BE SIGNIFICANT TO THE
PROTECTION OF MARINE FISHERIES OR WILDLIFE HABITAT, 310 CMR 10.33(3)
through (5) SHALL APPLY:
(3) Any project on land under a salt pond, on lands within 100 feet of the mean high water line
of a salt pond, or on land under a body of water adjacent to a salt pond shall not have an adverse
effect on the marine fisheries or wildlife habitat of such a salt pond caused by:
(a) alterations of water circulation;
(b) alterations in the distribution of sediment grain size and the relief or elevation of the
bottom topography;
(c) modifications in the flow of fresh and/or salt water;
(d) alterations in the productivity of plants, or
(e) alterations in water quality, including, but not limited to, other than normal fluctuations
in the level of dissolved oxygen, nutrients, temperature or turbidity, or the addition of
pollutants.
(4) Notwithstanding the provisions of 310 CMR 10.33(3), activities specifically required and
intended to maintain the depth and the opening of the salt pond to the ocean in order to maintain
or enhance the marine fisheries or for the specific purpose of fisheries management, may be
permitted.
(5) Notwithstanding the provisions of 310 CMR 10.33(3) and (4), no project may be permitted
which will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate
species, as identified by procedures established under 310 CMR 10.37.
10.34: Land Containing Shellfish
(1) Preamble. Land containing shellfish is found within certain of the resource areas under the
jurisdiction of M.G.L. c. 131, § 40. "Land containing shellfish" is also specifically one of the
interests of M.G.L. c. 131, § 40. The purpose of 310 CMR 10.34 is to identify those resource
areas likely to contain shellfish, to provide criteria for determining the significance of land
containing shellfish, and to establish regulations for projects which will affect such land.
Wetland Regulations – May 2008 Page 69
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.34: continued
Land containing shellfish is, under 310 CMR 10.34(3), significant to the protection of marine
fisheries as well as to the protection of the interest of land containing shellfish.
Shellfish are a valuable renewable resource. The maintenance of productive shellfish beds
not only assures the continuance of shellfish themselves, but also plays a direct role in supporting
fish stocks by providing a major food source. The young shellfish in the planktonic larval stage
that are produced in large quantities during spring and summer are an important source of food
for the young stages of marine fishes and many crustaceans.
When a resource area is found to be significant to the protection of land containing shellfish
under 310 CMR 10.34(3), and is, therefore, also significant to marine fisheries the following
factors are critical to the protection of those interests:
(a) shellfish,(b) water quality,
(c) water circulation, and(d) the natural relief, evaluation or distribution of sediment grain size of such land.
(2) Definitions.
Land containing shellfish means land under the ocean, tidal flats, rocky intertidal shores, salt
marshes and land under salt ponds when any such land contains shellfish.
Shellfish means the following species: Bay scallop (Argopecten irradians); Blue mussel
(Mytilus edulis); Ocean quahog (Arctica islandica); Oyster (Crassostrea virginica); Quahog
(Mercenaria merceneria); Razor clam (Ensis directus); Sea clam (Spisula solidissima); Sea
scallop (Placopecten magellanicus); Soft shell clam (Mya arenaria).
Shellfish constable means the official in a city or town, whether designated a constable, warden,
natural resources officer, or by some other name, in charge of enforcing the laws regulating the
harvest of shellfish.
(3) Significance. Land containing shellfish shall be found significant to the protection of land
containing shellfish and to the protection of marine fisheries when it has been identified and
mapped as follows:
(a) by the conservation commission or the Department in consultation with DMF and based
upon maps and designations of DMF, or
(b) by the conservation commission or the Department, based upon maps and written
documentation of the shellfish constable or the Department. In making such identification
and maps the following factors shall be taken into account and documented: the density of
shellfish, the size of the area and the historical and current importance of the area to
recreational or commercial shellfishing.
WHEN A RESOURCE AREA, INCLUDING LAND UNDER THE OCEAN, TIDAL
FLATS, ROCKY INTERTIDAL SHORES, SALT MARSHES, OR LAND UNDER SALT
PONDS IS DETERMINED TO BE SIGNIFICANT TO THE PROTECTION OF LAND
CONTAINING SHELLFISH AND THEREFORE TO THE PROTECTION OF MARINE
FISHERIES, 310 CMR 10.34(4) through (8) SHALL APPLY:
(4) Except as provided in 310 CMR 10.34(5), any project on land containing shellfish shall not
adversely affect such land or marine fisheries by a change in the productivity of such land caused
by:
(a) alterations of water circulation,
(b) alterations in relief elevation,
(c) the compacting of sediment by vehicular traffic,
(d) alterations in the distribution of sediment grain size,
(e) alterations in natural drainage from adjacent land, or
(f) changes in water quality, including, but not limited to, other than natural fluctuations in
the levels of salinity, dissolved oxygen, nutrients, temperature or turbidity, or the addition
of pollutants.
Wetland Regulations – May 2008 Page 70
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.34: continued
(5) Notwithstanding the provisions of 310 CMR 10.34(4), projects which temporarily have an
adverse effect on shellfish productivity but which do not permanently destroy the habitat may
be permitted if the land containing shellfish can and will be returned substantially to its former
productivity in less than one year from the commencement of work, unless an extension of the
Order of Conditions is granted, in which case such restoration shall be completed within one year
of such extension.
(6) In the case of land containing shellfish defined as significant in 310 CMR 10.34(3)(b) (i.e.,
those areas identified on the basis of maps and designations of the Shellfish Constable), except
in Areas of Critical Environmental Concern, the issuing authority may, after consultation with
the Shellfish Constable, permit the shellfish to be moved from such area under the guidelines of,and to a suitable location approved by, DMF, in order to permit a proposed project on such land.
Any such project shall not be commenced until after the moving and replanting of the shellfishhave been commenced.
(7) Notwithstanding 310 CMR 10.34(4) through 10.34(6), projects approved by DMF that are
specifically intended to increase the productivity of land containing shellfish may be permitted.Aquaculture projects approved by the appropriate local and state authority may also be permitted.
(8) Notwithstanding the provisions of 310 CMR 10.34(4) through (7), no project may be
permitted which will have any adverse effect on specified habitat of rare vertebrate or
invertebrate species, as identified by procedures established under 310 CMR 10.37.
10.35: Banks of or Land Under the Ocean, Ponds, Streams, Rivers, Lakes, or Creeks that Underlie an
Anadromous/Catadromous Fish Run ("Fish Run")
(1) Preamble. The banks of and land under the ocean, ponds, streams, rivers, lakes or creeks
that underlie an anadromous/catadromous fish run are significant to protection of marine
fisheries.
Anadromous and catadromous fish ("the fish") are renewable protein resources that provide
recreational, aesthetic and commercial benefits. In addition, throughout their life cycle such fish
are important components of freshwater, estuarine, and marine environments and are food
sources for other organisms.
The spawning migrations of such fish also provide a direct link between marine and
freshwater ecosystems. This link plays a role in maintaining the productivity of fisheries.
When a proposed project involves the dredging, filling, removing or altering of a bank of a
fish run, or land under the ocean, or under a pond, stream, river, lake or creek which is a fish run,
the issuing authority shall presume that such bank or land is significant to the protection of
marine fisheries. This presumption may be overcome only upon a clear showing that such bank
or land does not play a role in the protection of marine fisheries, and if the issuing authority
makes a written determination to that effect.
When such a bank of a fish run, or land under the ocean or under a pond, stream, river, lake
or creek which is a fish run is significant to the protection of marine fisheries, the following
factors are critical to the protection of such interest:
(a) the fish,
(b) accessibility of spawning areas,
(c) the volume or rate of the flow of water within spawning areas and migratory routes, and
(d) spawning and nursery grounds.
(2) Definitions.
Anadromous Fish means fish that enter fresh water from the ocean to spawn, such as alewives,
shad and salmon.
Wetland Regulations – May 2008 Page 71
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.35: continued
Catadromous Fish means fish that enter salt water from fresh water to spawn, such as eels.
Anadromous/Catadromous Fish Run means that area within estuaries, ponds, streams, creeks,
rivers, lakes or coastal waters, which is a spawning or feeding ground or passageway for
anadromous or catadromous fish and which is identified by DMF or has been mapped on theCoastal Atlas of the Coastal Zone Management Program. Such fish runs shall include those
areas which have historically served as fish runs and are either being restored or are planned to
be restored at the time the Notice of Intent is filed. For the purposes of 310 CMR 10.21 through10.37, such fish runs shall extend inland no further than the inland boundary of the coastal zone.
WHEN SUCH LAND OR BANK IS DETERMINED TO BE SIGNIFICANT TO THEPROTECTION OF MARINE FISHERIES, 310 CMR 10.35(3) through (5) SHALL APPLY:
(3) Any project on such land or bank shall not have an adverse effect on the anadromous orcatadromous fish run by:(a) impeding or obstructing the migration of the fish, unless DMF has determined that such
impeding or obstructing is acceptable, pursuant to its authority under M.G.L. c. 130, § 19;(b) changing the volume or rate of flow of water within the fish run; or(c) impairing the capacity of spawning or nursery habitats necessary to sustain the various
life stages of the fish.
(4) Unless otherwise allowed by DMF pursuant to M.G.L. c. 130, § 19, dredging, disposal of
dredged material or filling in a fish run shall be prohibited between March 15th and June 15th
in any year.
(5) Notwithstanding the provisions of 310 CMR 10.35(3), no project may be permitted which
will have any adverse effect on specified habitat sites of rare vertebrate or invertebrate species,as identified by procedures established under 310 CMR 10.37.
(10.36: Reserved. Variance provision is at 310 CMR 10.05(10))
10.37: Estimated Habitats of Rare Wildlife (for coastal wetlands)
If a project is within estimated habitat which is indicated on the most recent Estimated
Habitat Map of State-Listed Rare Wetlands Wildlife (if any) published by the Natural Heritage
and Endangered Species Program (hereinafter referred to as the Program), a fully completed copyof the Notice of Intent (including all plans, reports, and other materials required under 310 CMR10.05(4)(a)&(b)) for such project shall be sent to the Program via the U.S. Postal Service by
express or priority mail (or otherwise sent in a manner that guarantees delivery within two days).Such copy shall be sent no later than the date of the filing of the Notice of Intent with the issuingauthority. Proof of timely mailing or other delivery to the Program of the copy of such Notice
of Intent shall be included in the Notice of Intent which is submitted to the issuing authority andsent to the Department's regional office.Estimated Habitat Maps shall be based on the estimated geographical extent of the habitats
of all state-listed vertebrate and invertebrate animal species for which a reported occurrence
within the last 25 years has been accepted by the Program and incorporated into its official database.
Within 30 days of the filing of such a Notice of Intent with the issuing authority, the Program
shall determine whether any state-listed species identified on the aforementioned map are likelyto continue to be located on or near the site of the original occurrence and, if so, whether the area
to be altered by the proposed project is in fact part of such species' habitat. Such determination
shall be presumed by the issuing authority to be correct. Any proposed project which would altera resource area that is not located on the most recent Estimated Habitat Map (if any) provided
to the conservation commission, shall be presumed not to be within a rare species' habitat. Both
of these presumptions are rebuttable and may be overcome upon a clear showing to the contrary.If the issuing authority fails to receive a response from the Program within 30 days of the filing
of such a Notice of Intent, a copy of which was received by the Program in a timely manner, it
shall issue its Order of Conditions based on available information; however, the fact that aproposed project would alter a resource area that is located on an Estimated Habitat Map shall
not be considered sufficient evidence in itself that such project is in fact within the habitat of a
rare species.
Wetland Regulations – May 2008 Page 72
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.37: continued
If the Program determines that a resource area which would be altered by a proposed project
is in fact within the habitat of a state-listed species, it shall provide in writing to the applicant and
to the Conservation Commission and the Department, the identification of the species whose
habitat would be altered by the proposed project, and all other relevant information which the
Program has regarding the species' location and habitat requirements, insofar as such information
may assist the applicant and the issuing authority to determine whether the project is or can be
designed so as to meet the performance standard set in 310 CMR 10.37.
Notwithstanding 310 CMR 10.24(7) and 10.25 and 310 CMR 10.27 through 10.35, if a
proposed project is found by the issuing authority to alter a resource area which is part of the
habitat of a state-listed species, such project shall not be permitted to have any short or long term
adverse effects on the habitat of the local population of that species. A determination of whether
or not a proposed project will have such an adverse effect shall be made by the issuing authority.
However, a written opinion of the Program on whether or not a proposed project will have such
an adverse effect shall be presumed by the issuing authority to be correct. This presumption is
rebuttable and may be overcome upon a clear showing to the contrary.
The conservation commission shall not issue an Order of Conditions under 310 CMR
10.05(6) regarding any such project for at least 30 days after the filing of the Notice of Intent,
unless the Program before such time period has elapsed has either determined that the resource
area(s) which would be altered by the project is not in fact within the habitat of a state-listed
species or, if it has determined that such resource area(s) is in fact within rare species habitat,
rendered a written opinion as to whether the project will have an adverse effect on that habitat.
Notwithstanding any other provision of 310 CMR 10.37, should an Environmental Impact
Report be required for a proposed project under the M.G.L. c. 60, §§ 6 through 62H, as
determined by 301 CMR 11.00 the performance standard established under 310 CMR 10.37 shall
only apply to proposed projects which would alter the habitat of a rare species for which an
occurrence has been entered into the official data base of the Massachusetts Natural Heritage and
Endangered Species Program prior to the time that the Secretary of the Executive Office of
Environmental Affairs has determined, in accordance with the provisions of 301 CMR 11.09(4),
that a final Environmental Impact Report for that project adequately and properly complies with
the M.G.L. c. 30, §§ 6 through 62H (unless, subsequent to that determination, the Secretary
requires supplemental information concerning state-listed species, in accordance with the
provisions of 301 CMR 11.17).
10.51: Introduction
310 CMR 10.51 through 10.60 applies to all work which will remove, fill, dredge or alter any
bank, bordering vegetated wetland, land under water bodies and waterways, land subject to
flooding or riverfront area. 310 CMR 10.51 through 10.60 pertains to inland (as opposed to
coastal) wetlands, and is promulgated in addition to 310 CMR 10.01 through 10.10 and
310 CMR 10.21 through 10.37. A project may be subject to regulation under both 310 CMR
10.01 through 10.10 and 310 CMR 10.21 through 10.37, in which case compliance with all
applicable regulations is required.
310 CMR 10.51 through 10.60 is grouped into five resource areas. Each section begins with
a Preamble which specifies the interests identified in M.G.L. c. 131, § 40 to which that resource
area is or is likely to be significant. The next subsection defines the resource area and describes
the characteristics of that area which are critical to the protection of the interests so identified.
The next subsection sets forth the presumptions concerning the significance of the resource area.
The last subsection contains the general performance standards to be applied to any work that
will remove, fill, dredge or alter the resource area.
10.52: Purpose
310 CMR 10.51 through 10.60 is intended to establish criteria and standards for the uniform
and coordinated administration of the provisions of M.G.L. c. 131, § 40. It is intended to ensure
that development in and near inland wetlands is sited, designed, constructed and maintained in
a manner that protects the public interests identified in M.G.L. c. 131, § 40 and served by these
resource areas.
Wetland Regulations – May 2008 Page 73
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.52: continued
310 CMR 10.51 through 10.60 is intended to ensure coordination between the divisions of
the Department and between the Department and other EOEA agencies; and to ensure
consideration by the Department of relevant policies, laws or programs of other EOEA agencies.
310 CMR 10.51 through 10.60 is, in addition, intended to be consistent with and form a part of
the Commonwealth's Coastal Zone Management Program as it has been promulgated and defined
by 301 CMR 21.00 issued pursuant to M.G.L. c. 21A and entitled "Establishment of the Coastal
Zone Management Program by the Executive Office of Environmental Affairs". 310 CMR 10.51
through 10.60, however, is adopted independently under M.G.L. c. 131, § 40 and would remain
in full force and effect in the absence of 301 CMR 21.00.
310 CMR 10.51 through 10.60 is intended to notify both persons proposing work in Areas
Subject to Protection Under M.G.L. c. 131, § 40 and those regulating that work as to the
performance standards that should be applied. These standards are intended to identify the level
of protection that the issuing authority must impose in order to contribute to the protection of the
interests identified in M.G.L. c. 131, § 40. It is the responsibility of the person proposing work
to design and complete his project in conformance with these performance standards. It is the
responsibility of the issuing authority to impose such conditions on a proposed project as to
ensure that the project is designed and completed in a manner consistent with these standards.
10.53: General Provisions
(1) If the issuing authority determines that a resource area is significant to an interest identified
in M.G.L. c. 131, § 40 for which no presumption is stated in the Preamble to the applicable
section, the issuing authority shall impose such conditions as are necessary to contribute to the
protection of such interests. For work in the buffer zone subject to review under 310 CMR
10.02(2)(b)3., the issuing authority shall impose conditions to protect the interests of the Act
identified for the adjacent resource area. The potential for adverse impacts to resource areas
from work in the buffer zone may increase with the extent of the work and the proximity to the
resource area. The issuing authority may consider the characteristics of the buffer zone, such as
the presence of steep slopes, that may increase the potential for adverse impacts on resource
areas. Conditions may include limitations on the scope and location of work in the buffer zone
as necessary to avoid alteration of resource areas. The issuing authority may require erosion and
sedimentation controls during construction, a clear limit of work, and the preservation of natural
vegetation adjacent to the resource area and/or other measures commensurate with the scope and
location of the work within the buffer zone to protect the interests of the Act. Where a buffer
zone has already been developed, the issuing authority may consider the extent of existing
development in its review of subsequent proposed work and, where prior development is
extensive, may consider measures such as the restoration of natural vegetation adjacent to a
resource area to protect the interest of the Act. The purpose of preconstruction review of work
in the buffer zone is to ensure that adjacent resource areas are not adversely affected during or
after completion of the work.
(2) When the site of a proposed project is subject to a Restriction Order which has been duly
recorded under the provisions of M.G.L. c. 131, § 40A, such a project shall conform to both the
provisions contained in that Order and 310 CMR 10.51 through 10.60.
(3) Notwithstanding the provisions of 310 CMR 10.54 through 10.58 and 10.60, the issuing
authority may issue an Order of Conditions and impose such conditions as will contribute to the
interests identified in M.G.L. c. 131, § 40 permitting the following limited projects (although no
such project may be permitted which will have any adverse effect on specified habitat sites of
rare vertebrate or invertebrate species, as identified by procedures established under 310 CMR
10.59). In the exercise of this discretion, the issuing authority shall consider the magnitude of
the alteration and the significance of the project site to the interests identified in M.G.L. c. 131,
§ 40, the availability of reasonable alternatives to the proposed activity, the extent to which
adverse impacts are minimized, and the extent to which mitigation measures, including
replication or restoration, are provided to contribute to the protection of the interests identified
in M.G.L. c. 131, § 40.

3. the surface vegetation and contours of the area shall be substantially restored; and
4. all sewer lines shall be constructed to minimize inflow and leakage.
(e) The construction and maintenance of a new roadway or driveway of minimum legal and
practical width acceptable to the planning board, where reasonable alternative means of
access from a public way to an upland area of the same owner is unavailable. Such roadway
or driveway shall be constructed in a manner which does not restrict the flow of water.
Reasonable alternative means of access may include any previously or currently available
alternatives such as realignment or reconfiguration of the project to conform to 310 CMR
10.54 to 310 CMR 10.58 or to otherwise minimize adverse impacts on resource areas. The
issuing authority may require the applicant to utilize access over an adjacent parcel of land
currently or formerly owned by the applicant, or in which the applicant has, or can obtain,
an ownership interest. The applicant shall design the roadway or driveway according to the
minimum length and width acceptable to the Planning Board, and shall present reasonable
alternative means of access to the Board. The applicant shall provide replication of
bordering vegetated wetlands and compensatory flood storage to the extent practicable. In
the Certificate of Compliance, the issuing authority may continue a condition imposed in the

10.54: Bank (Naturally Occurring Banks and Beaches)
(1) Preamble. Banks are likely to be significant to public or private water supply, to groundwater supply, to flood control, to storm damage prevention, to the prevention of pollution and
to the protection of fisheries and wildlife habitat. Where Banks are composed of concrete,asphalt or other artificial impervious material, said Banks are likely to be significant to floodcontrol and storm damage prevention.Banks are areas where ground water discharges to the surface and where, under somecircumstances, surface water recharges the ground water.
Where Banks are partially or totally vegetated, the vegetation serves to maintain the Banks'stability, which in turn protects water quality by reducing erosion and siltation.Banks may also provide shade that moderates water temperatures, as well as providing
breeding habitat, escape cover and food, all of which are significant to the protection of fisheries.Banks which drop off quickly or overhang the water's edge often contain numerous undercuts
which are favorite hiding spots for important game species such as largemouth bass (Micropterussalmoides).The topography, plant community composition and structure, and soil structure of banks
together provide important food, shelter, migratory and overwintering areas, and breeding areasfor wildlife. Topography plays a role in determining the suitability of banks to serve asburrowing or feeding habitat. Soil structure also plays a role in determining the suitability for
burrowing, hibernation and other cover. Bank topography and soil structure impact the bank'svegetative structure, as well. Bushes and other undergrowth, trees, vegetation extending from
the bank into the water, and vegetation growing along the water's edge are also important to awide variety of wildlife. A number of tubers and berry bushes also grow in banks and serve asimportant food for wildlife. Finally, banks may provide important shelter for wildlife which
needs to move between wetland areas.
Wetland Regulations – May 2008 Page 83
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.54: continued
Banks act to confine floodwaters during the most frequent storms, preventing the spread of
water to adjacent land. Because Banks confine water during such storms to an established
channel they maintain water temperatures and depths necessary for the protection of fisheries.
The maintenance of cool water temperatures during warm weather is critical to the survival of
important game species such as brook trout (Salvelinus frontinalis), rainbow trout
(Oncorhynchus Mykiss) and brown trout (Salmo trutta). An alteration of a Bank that permits
water to frequently and consistently spread over a large and more shallow area increases the
amount of property which is routinely flooded, as well as elevating water temperature and
reducing fish habitat within the main channel, particularly during warm weather.
(2) Definition, Critical Characteristics and Boundary.
(a) A Bank is the portion of the land surface which normally abuts and confines a water
body. It occurs between a water body and a vegetated bordering wetland and adjacent flood
plain, or, in the absence of these, it occurs between a water body and an upland.
A Bank may be partially or totally vegetated, or it may be comprised of exposed soil,
gravel or stone.
(b) The physical characteristics of a Bank, as well as its location, as described in the
foregoing 310 CMR 10.54(2)(a), are critical to the protection of the interests specified in
310 CMR 10.54(1).
(c) The upper boundary of a Bank is the first observable break in the slope or the mean
annual flood level, whichever is lower. The lower boundary of a Bank is the mean annual
low flow level.
(3) Presumption. Where a proposed activity involves the removing, filling, dredging or altering
of a Bank, the issuing authority shall presume that such area is significant to the interests
specified in 310 CMR 10.54(1). This presumption is rebuttable and may be overcome upon a
clear showing that the Bank does not play a role in the protection of said interests. In the event
that the presumption is deemed to have been overcome, the issuing authority shall make a written
determination to this effect, setting forth its grounds (Form 6).
(4) General Performance Standard.
(a) Where the presumption set forth in 310 CMR 10.54(3) is not overcome, any proposed
work on a Bank shall not impair the following:
1. the physical stability of the Bank;
2. the water carrying capacity of the existing channel within the Bank;
3. ground water and surface water quality;
4. the capacity of the Bank to provide breeding habitat, escape cover and food for
fisheries;
5. the capacity of the Bank to provide important wildlife habitat functions. A project
or projects on a single lot, for which Notice(s) of Intent is filed on or after November 1,
1987, that (cumulatively) alter(s) up to 10% or 50 feet (whichever is less) of the length
of the bank found to be significant to the protection of wildlife habitat, shall not be
deemed to impair its capacity to provide important wildlife habitat functions. Additional
alterations beyond the above threshold may be permitted if they will have no adverse
effects on wildlife habitat, as determined by procedures contained in 310 CMR 10.60.
(b) Notwithstanding the provisions of 310 CMR 10.54(4)(a), structures may be permitted
in or on a Bank when required to prevent flood damage to facilities, buildings and roads
constructed prior to the effective date of 310 CMR 10.51 through 10.60 or constructed
pursuant to a Notice of Intent filed prior to the effective date of 310 CMR 10.51 through
10.60 (April 1, 1983), including the renovation or reconstruction (but not substantial
enlargement) of such facilities, buildings and roads, provided that the following requirements
are met:
1. The proposed protective structure, renovation or reconstruction is designed and
constructed using best practical measures so as to minimize adverse effects on the
characteristics and functions of the resource area;
Wetland Regulations – May 2008 Page 84
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION

2. The applicant demonstrates that there is no reasonable method of protecting,
renovating or rebuilding the facility in question other than the one proposed.
(c) Notwithstanding the provisions of 310 CMR 10.54(4)(a) or (b), no project may be
permitted which will have any adverse effect on specified habitat sites of rare vertebrate or
invertebrate species, as identified by procedures established under 310 CMR 10.59.
10.55: Bordering Vegetated Wetlands (Wet Meadows, Marshes, Swamps and Bogs)
(1) Preamble. Bordering Vegetated Wetlands are likely to be significant to public or private
water supply, to ground water supply, to flood control, to storm damage prevention, to
prevention of pollution, to the protection of fisheries and to wildlife habitat.
The plants and soils of Bordering Vegetated Wetlands remove or detain sediments, nutrients
(such as nitrogen and phosphorous) and toxic substances (such as heavy metal compounds) that
occur in run-off and flood waters.
Some nutrients and toxic substances are detained for years in plant root systems or in the
soils. Others are held by plants during the growing season and released as the plants decay in
the fall and winter. This latter phenomenon delays the impacts of nutrients and toxins until the
cold weather period, when such impacts are less likely to reduce water quality.
Bordering Vegetated Wetlands are areas where ground water discharges to the surface and
where, under some circumstances, surface water discharges to the ground water.
The profusion of vegetation in Bordering Vegetated Wetlands acts to slow down and reduce
the passage of flood waters during periods of peak flows by providing temporary flood water
storage and by facilitating water removal through evaporation and transpiration. This process
reduces downstream flood crests and resulting damage to private and public property. During
dry periods the water retained in Bordering Vegetated Wetlands is essential to the maintenance
of base flow levels in rivers and streams, which in turn is important to the protection of water
quality and water supplies.
The Act defines freshwater wetlands by hydrology and vegetation. Hydrology is the driving
force which creates wetlands, but it is a transient, temporal parameter. The presence of water
at or near the ground surface during a significant portion of the year supports, and in fact
promotes, the growth of wetland indicator plants. Prolonged or frequent saturation or inundation
also produces hydric soils, and creates anaerobic conditions that favor the growth of wetland
indicator plants. Hydric soils are direct indicators of long-term hydrologic conditions and are
present throughout the year.
Wetland vegetation supports a wide variety of insects, reptiles, amphibians, small mammals
and birds which are a source of food for important game fish. Bluegills (Lepomis macrochirus),
pumpkinseeds (Lepomis gibbosus), yellow perch (Perca flavescens), rock bass (Ambloplites
rupestris) and all trout species feed upon nonaquatic insects. Large-mouth bass (Micropterus
salmoides), chain pickerel (Esox niger) and northern pike (Esox lucius) feed upon small
mammals, snakes, nonaquatic insects, birds and amphibians.
Wetland vegetation provides shade which moderates water temperatures important to fish
life. Wetlands flooded by adjacent water bodies and waterways provide food, breeding habitat
and cover for fish. Fish populations in the larval stage are particularly dependent upon food
provided by over-bank flooding which occurs during peak flow periods (extreme storms) because
most river and stream channels do not provide sufficient quantities of the microscopic plant and
animal life required for food.
Bordering vegetated wetlands are probably the Commonwealth's most important inland
habitat for wildlife. The hydrologic regime, plant community composition and structure, soil
composition and structure, topography, and water chemistry of bordering vegetated wetlands
provide important food, shelter, migratory and overwintering areas, and breeding areas for many
birds, mammals, amphibians and reptiles. A wide variety of vegetated wetland plants, the nature
of which are determined in large part by the depth and duration of water, as well as soil and
water composition, are utilized by varied species as important areas for mating, nesting, brood
rearing, shelter and food (directly and indirectly). The diversity and interspersion of the
vegetative structure is also important in determining the nature of its wildlife habitat. Different
habitat characteristics are used by different wildlife species during summer, winter and migratory
seasons.

10.55: continued
Although the vegetational community can often be analyzed to establish an accurate wetland
boundary, sole reliance on the presence of wetland indicator plants can be misleading because
some species thrive in both uplands and wetlands. Gently sloping areas often produce large
transitional zones where the vegetational boundary is difficult to delineate. Hydrology can
supplement vegetative criteria to enhance the technical accuracy, consistency, and credibility of
wetland boundary delineations, and are especially useful for analyzing disturbed sites.
(2) Definition, Critical Characteristics and Boundary.
(a) Bordering Vegetated Wetlands are freshwater wetlands which border on creeks, rivers,
streams, ponds and lakes. The types of freshwater wetlands are wet meadows, marshes,
swamps and bogs. Bordering Vegetated Wetlands are areas where the soils are saturated
and/or inundated such that they support a predominance of wetland indicator plants. The
ground and surface water regime and the vegetational community which occur in each type
of freshwater wetland are specified in M.G.L. c. 131, § 40.
(b) The physical characteristics of Bordering Vegetated Wetlands, as described in 310 CMR
10.55(2)(a), are critical to the protection of the interests specified in 310 CMR 10.55(1).
(c) The boundary of Bordering Vegetated Wetlands is the line within which 50% or
more of the vegetational community consists of wetland indicator plants and saturated
or inundated conditions exist. Wetland indicator plants shall include but not necessarily
be limited to those plant species identified in the Act. Wetland indicator plants are also
those classified in the indicator categories of Facultative, Facultative+, Facultative
Wetland-, Facultative Wetland, Facultative Wetland+, or Obligate Wetland in the
National List of Plant Species That Occur in Wetlands: Massachusetts (Fish & Wildlife
Service, U.S. Department of the Interior, 1988) or plants exhibiting physiological or
morphological adaptations to life in saturated or inundated conditions.
1. Areas containing a predominance of wetland indicator plants are presumed to indicate
the presence of saturated or inundated conditions. Therefore, the boundary as determined
by 50% or more wetland indicator plants shall be presumed accurate when:
a. all dominant species have an indicator status of obligate, facultative wetland+,
facultative wetland, or facultative wetland- and the slope is distinct or abrupt between
the upland plant community and the wetland plant community;
b. the area where the work will occur is clearly limited to the buffer zone; or
c. the issuing authority determines that sole reliance on wetland indicator plants will
yield an accurate delineation.
2. When the boundary is not presumed accurate as described in 310 CMR
10.55(2)(c)1.a. through c. or to overcome the presumption, credible evidence shall be
submitted by a competent source demonstrating that the boundary of Bordering
Vegetated Wetlands is the line within which 50% or more of the vegetational community
consists of wetland indicator plants and saturated or inundated conditions exist. The
issuing authority must evaluate vegetation and indicators of saturated or inundated
conditions if submitted by a credible source, or may require credible evidence of
saturated or inundated conditions when determining the boundary. Indicators of saturated
or inundated conditions sufficient to support wetland indicator plants shall include one
or more of the following:
a. groundwater, including the capillary fringe, within a major portion of the root
zone;
b. observation of prolonged or frequent flowing or standing surface water;
c. characteristics of hydric soils.
3. Where an area has been disturbed (e.g. by cutting, filling, or cultivation), the
boundary is the line within which there are indicators of saturated or inundated
conditions sufficient to support a predominance of wetland indicator plants, a
predominance of wetland indicator plants, or credible evidence from a competent source
that the area supported or would support under undisturbed conditions a predominance
of wetland indicator plants prior to the disturbance.

Vegetated Wetland when;
1. said portion has a surface area less than 500 square feet;
2. said portion extends in a distinct linear configuration ("finger-like") into adjacent
uplands; and
3. in the judgment of the issuing authority it is not reasonable to scale down, redesign
or otherwise change the proposed work so that it could be completed without loss of said
wetland.
(d) Notwithstanding the provisions of 310 CMR 10.55(4)(a),(b) and (c), no project may be
permitted which will have any adverse effect on specified habitat sites of rare vertebrate or

10.56: Land Under Water Bodies and Waterways (Under any Creek, River, Stream, Pond or Lake)
(1) Preamble. Land Under Water Bodies and Waterways is likely to be significant to public and
private water supply, to ground water supply, to flood control, to storm damage prevention, to
prevention of pollution and to protection of fisheries and wildlife habitat. Where such land is
composed of concrete, asphalt or other artificial impervious material, said land is likely to be
significant to flood control and storm damage prevention.Where Land Under Water Bodies and Waterways is composed of pervious material, such
land represents a point of exchange between surface and ground water.The physical nature of Land Under Water Bodies and Waterways is highly variable, rangingfrom deep organic and fine sedimentary deposits to rocks and bedrock. The organic soils andsediments play an important role in the process of detaining and removing dissolved and
particulate nutrients (such as nitrogen and phosphorous) from the surface water above. They alsoserve as traps for toxic substances (such as heavy metal compounds).
Land Under Water Bodies and Waterways, in conjunction with banks, serves to confine
floodwater within a definite channel during the most frequent storms. Filling within this channel
blocks flows which in turn causes backwater and overbank flooding during such storms. An
alteration of Land Under Water Bodies and Waterways that causes water to frequently spread out
over a larger area at a lower depth increases the amount of property which is routinely flooded.
Additionally, it results in an elevation of water temperature and a decrease in habitat in the main
channel, both of which are detrimental to fisheries, particularly during periods of warm weather
and low flows.
Land under rivers, streams and creeks that is composed of gravel allows the circulation of
cold, well oxygenated water necessary for the survival of important game fish species such as
brook trout (Salvelinus frontinalis), rainbow trout (Oncorhynchus mykiss), brown trout (Salmo
trutto) and atlantic salmon (Salmon salar). River, stream and creek bottoms with a diverse
structure composed of gravel, large and small boulders and rock outcrops provides escape cover
and resting areas for the above mentioned game fish species (salmonids). Such bottom type also
provides areas for the production of aquatic insects essential to fisheries.
Land under ponds and lakes is vital to a large assortment of warm water fish during spawning
periods. Species such as large mouth bass (Micropterus salmoides), smallmouth bass
(Micropterus dolomieui), blue gills (Lepomis macrochirus), pumpkinseeds (Lepomis gibbosus),
black crappie (Pomoxis nigromaculatus) and rock bass (Ambloplites rupestris) build nests on the
lake and bottom substrates within which they shed fertilize their eggs.
The plant community composition and structure, hydrologic regime, topography, soil
composition and water quality of land under water bodies and waterways provide important
food, shelter, migratory and overwintering areas, and breeding areas for wildlife. Certain
submerged, rooted vegetation is eaten by water fowl and some mammals. Some amphibians (as
well as some invertebrate species eaten by vertebrate wildlife) attach their eggs to such
vegetation. Some aquatic vegetation protruding out of the water is also used for nesting, and
many species use dead vegetation resting on land under water but protruding above the surface
for feeding and basking Soil composition is also important for hibernation and for animals
which begin to burrow their tunnels under water. Hydrologic regime, topography, and water
quality not only affect vegetation, but also determine which species feed in an area.
(2) Definition, Critical Characteristics and Boundaries.
(a) Land Under Water Bodies and Waterways is the land beneath any creek, river, stream,
pond or lake. Said land may be composed of organic muck or peat, fine sediments, rocks or
bedrock.
(b) The physical characteristics and location of Land Under Water Bodies and Waterways
specified in 310 CMR 10.56(2)(a) are critical to the protection of the interests specified in
310 CMR 10.56(1).
(c) The boundary of Land Under Water Bodies and Waterways is the mean annual low
water level.

(3) Presumption. Where a project involves removing, filling, dredging or altering of Land
Under Water Bodies and Waterways, the issuing authority shall presume that such area issignificant to the interests specified in 310 CMR 10.56(1). This presumption is rebuttable and
may be overcome upon a clear showing that said land does not play a role in the protection of
said interests. In the event that the presumption is deemed to have been overcome, the issuingauthority shall make a written determination to this effect, setting forth the grounds (Form 6).
(4) General Performance Standards.(a) Where the presumption set forth in 310 CMR 10.56(3) is not overcome, any proposed
work within Land Under Water Bodies and Waterways shall not impair the following:
1. The water carrying capacity within the defined channel, which is provided by saidland in conjunction with the banks;2. Ground and surface water quality;
3. The capacity of said land to provide breeding habitat, escape cover and food forfisheries; and4. The capacity of said land to provide important wildlife habitat functions. A project
or projects on a single lot, for which Notice(s) of intent is filed on or after November 1,1987, that (cumulatively) alter(s) up to 10% or 5,000 square feet (whichever is less) ofland in this resource area found to be significant to the protection of wildlife habitat, shall
not be deemed to impair its capacity to provide important wildlife habitat functions.
Additional alterations beyond the above threshold may be permitted if they will have noadverse effects on wildlife habitat, as determined by procedures established under
310 CMR 10.60.
(b) Notwithstanding the provisions of 310 CMR 10.56(4)(a), the issuing authority may issuean Order in accordance with M.G.L. c. 131, § 40 to maintain or improve boat channels within
Land Under Water Bodies and Waterways when said work is designed and carried out using
the best practical measures so as to minimize adverse effects such as the suspension ortransport of pollutants, increases in turbidity, the smothering of bottom organisms, the
accumulation of pollutants by organisms or the destruction of fisheries habitat or nutrient
source areas.(c) Notwithstanding the provisions of 310 CMR 10.56(4)(a) or (b), no project may be
permitted which will have any adverse effect on specified habitat sites of rare vertebrate or
invertebrate species, as identified by procedures established under 310 CMR 10.59.
10.57: Land Subject to Flooding (Bordering and Isolated Areas)
(1) Preamble.
(a) Bordering Land Subject to Flooding:
1. Bordering Land Subject to Flooding is an area which floods from a rise in a borderingwaterway or water body. Such areas are likely to be significant to flood control andstorm damage prevention.
2. Bordering Land Subject to Flooding provides a temporary storage area for floodwater which has overtopped the bank of the main channel of a creek, river or stream orthe basin of a pond or lake. During periods of peak run-off, flood waters are both
retained (i.e., slowly released through evaporation and percolation) and detained (slowly
released through surface discharge) by Bordering Land Subject to Flooding. Over time,incremental filling of these areas causes increases in the extent and level of flooding by
eliminating flood storage volume or by restricting flows, thereby causing increases in
damage to public and private properties.3. Certain portions of Bordering Land Subject to Flooding are also likely to be
significant to the protection of wildlife habitat. These include all areas on the ten year
floodplain or within 100 feet of the bank or bordering vegetated wetland (whichever isfurther from the water body or waterway, so long as such area is contained within the 100
year floodplain), and all vernal pool habitat on the 100 year floodplain, except for those
portions of which have been so extensively altered by human activity that their importantwildlife habitat functions have been effectively eliminated (such "altered" areas include
paved and gravelled areas, golf courses, cemetaries, playgrounds, landfills, fairgrounds,
quarries, gravel pits, buildings, lawns, gardens, roadways (including median strips, areasenclosed within highway interchanges, shoulders, and embankments), railroad tracks
(including ballast and embankments), and similar areas lawfully existing on November
1, 1987 and maintained as such since that time).
Wetland Regulations – May 2008 Page 89
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.57: continued
The hydrologic regime, plant community composition and structure, topography, soil
composition and proximity to water bodies and bordering vegetated wetlands of these
portions of bordering land subject to flooding provide important food, shelter, migratory
and overwintering areas, and breeding areas for wildlife. Nutrients from flood waters,
as well as the inundation of floodplain soil, create important wildlife habitat
characteristics, such as richness and diversity of soil and vegetation. A great many
species require or prefer habitat which is as close as possible to water and/or has moist
conditions, characteristics generally present on lower floodplains. Similarly, lower
floodplains, because of their proximity to water and vegetated wetlands, can provide
important shelter for wildlife which needs to migrate between such areas, or between
such areas and uplands. The "edge" where floodplain habitat borders vegetated wetlandsor water bodies is frequently very high in wildlife richness and diversity. Similar "edges"
may be found elsewhere the lower floodplain, where differences in topography andfrequency of flooding have created varied soil and plant community composition andstructure.Finally, vernal pool habitat is found at various locations throughout the 100 yearfloodplain, the pool itself generally formed by meander scars, or sloughs left after themain water channel has changed course. These pools are essential breeding sites for
certain amphibians which require isolated areas that are generally flooded for at least twocontinuous months in the spring and/or summer and are free from fish predators. Most
of these amphibians remain near the breeding pool during the remainder of their lifecyle.
Many reptiles, birds and mammals also feed here.
(b) Isolated Land Subject to Flooding:
1. Isolated Land Subject to Flooding is an isolated depression or a closed basin which
serves as a ponding area for run-off or high ground water which has risen above the
ground surface. Such areas are likely to be locally significant to flood control and storm
damage prevention. In addition, where such areas are underlain by pervious material they
are likely to be significant to public or private water supply and to ground water supply.
Where such areas are underlain by pervious material covered by a mat of organic peat
and muck, they are also likely to be significant to the prevention of pollution. Finally,
where such areas are vernal pool habitat, they are significant to the protection of wildlife
habitat.
2. Isolated Land Subject to Flooding provides a temporary storage area where run-off
and high ground water pond and slowly evaporate or percolate into the substrate. Filling
causes lateral displacement of the ponded water onto contiguous properties, which may
in turn result in damage to said properties.
3. Isolated Land Subject to Flooding, where it is underlain by pervious material,
provides a point of exchange between ground and surface waters. Contaminants
introduced into said area, such as septic system discharges and road salts, find easy
access into the ground water and neighboring wells. Where these conditions occur and
a mat of organic peat or muck covers the substrate of the area, said mat serves to detain
and remove contaminants which might otherwise enter the ground water and neighboring
wells.
4. Isolated Land Subject to Flooding, where it is vernal pool habitat, is an essential
breeding site for certain amphibians which require isolated areas that are generally
flooded for at least two continous months in the spring and/or summer and are free from
fish predators. Most of these amphibians remain near the breeding pool during the
remainder of their lifecycle. Many reptiles, birds and mammals also feed here.
(2) Definitions, Critical Characteristics and Boundaries.
(a) Bordering Land Subject to Flooding:
1. Bordering Land Subject to Flooding is an area with low, flat topography adjacent to
and inundated by flood waters rising from creeks, rivers, streams, ponds or lakes. It
extends from the banks of these waterways and water bodies; where a bordering
vegetated wetland occurs, it extends from said wetland.
2. The topography and location of Bordering Land Subject to Flooding specified in the
foregoing 310 CMR 10.57(2)(a)1. are critical to the protection of the interests specified
in 310 CMR 10.57(1)(a). Where Bordering Land Subject to Flooding is significant to
the protection of wildlife habitat, the physical characteristics as described in the
foregoing 310 CMR 10.57(1)(a)(3) are critical to the protection of that interest.
Wetland Regulations – May 2008 Page 90

10.57: continued
3. The boundary of Bordering Land Subject to Flooding is the estimated maximum
lateral extent of flood water which will theoretically result from the statistical 100-year
frequency storm. Said boundary shall be that determined by reference to the most
recently available flood profile data prepared for the community within which the work
is proposed under the National Flood Insurance Program (NFIP, currently administered
by the Federal Emergency Management Agency, successor to the U.S. Department of
Housing and Urban Development). Said boundary, so determined, shall be presumed
accurate. This presumption may be overcome only by credible evidence from a
registered professional engineer or other professional competent in such matters.
Where NFIP Profile data is unavailable, the boundary of Bordering Land Subject to
Flooding shall be the maximum lateral extent of flood water which has been observedor recorded. In the event of a conflict, the issuing authority may require the applicant to
determine the boundary of Bordering Land Subject to Flooding by engineeringcalculations which shall be:a. based upon a design storm of seven inches of precipitation in 24 hours (i.e., aType III Rainfall, as defined by the U.S. Soil Conservation Service);b. based upon the standard methodologies set forth in U.S. Soil ConservationService Technical Release No. 55, Urban Hydrology for Small Watersheds and
Section 4 of the U.S. Soil Conservation Service, National Engineering Hydrology
Handbook; and
c. prepared by a registered professional engineer or other professional competent in
such matters.
4. The boundary of the ten year floodplain is the estimated maximum lateral extent of
the flood water which will theoretically result from the statistical ten-year frequency
storm. Said boundary shall be determined as specified under 310 CMR 10.57(2)(a)3.,
except that where NFIP Profile data is unavailable, the boundary shall be the maximum
lateral extent of flood water which has been observed or recorded during a 10 year
frequency storm and, in the event of conflict, engineering calculations under 310 CMR
10.57(2)(a)3.a. shall be based on a design storm of 48/10 (4.8) inches of precipitation in
24 hours.
5. The only portions of this resource area which shall be presumed to be vernal pool
habitat are those that have been certified as such by the Massachusetts Division of
Fisheries and Wildlife, where said Division has forwarded maps and other information
needed to identify the location of such habitat to the Conservation Commission and DEP
prior to the filing of each Notice of Intent or Abbreviated Notice of Intent regarding that
portion. Such presumption is rebuttable, and may be overcome upon a clear showing to
the contrary. However, notwithstanding any other provision of 310 CMR 10.57, should
an Environmental Impact Report be required for a proposed project as determined by 301
CMR 11.00 the performance standard established under this Section regarding vernal
pool habitat shall only apply to proposed projects which would alter such habitats as have
been identified prior to the time that the Secretary of the Executive Office of
Environmental Affairs has determined, in accordance with the provisions of 301 CMR
11.09(4), that a final Environmental Impact Report for that project adequately and
properly complies with the M.G.L. c. 30, § 6 through 62H (unless, subsequent to that
determination, the Secretary requires supplemental information concerning vernal pool
habitat, in accordance with the provisions of 301 CMR 11.17).
6. The boundary of vernal pool habitat is that certified by the Massachusetts Division
of Fisheries and Wildlife. In the event of a conflict of opinion, or the lack of a clear
boundary delineation certified by the Division of Fisheries and Wildlife, the applicant
may submit an opinion certified by a registered professional engineer, supported by
engineering calculations, as to the probable extent of said habitat. Said calculations shall
be prepared in accordance with the general requirements set forth in 310 CMR
10.57(2)(a)3.a. through c., except that the maximum extent of said water shall be based
upon the total volume (rather than peak rate) of run-off from the drainage area
contributing to the vernal pool and shall be further based upon a design storm of 26/10
(2.6) inches (rather than seven inches) of precipitation in 24 hours. Vernal pool habitat
shall include the area within 100 feet of the boundary of the vernal pool itself, insofar as
such area is contained within the boundaries of this resource area.

(b) Isolated Land Subject to Flooding:
1. Isolated Land Subject to Flooding is an isolated depression or closed basin without
an inlet or an outlet. It is an area which at least once a year confines standing water to
a volume of at least ¼ acre-feet and to an average depth of at least six inches.
Isolated Land Subject to Flooding may be underlain by pervious material, which in
turn may be covered by a mat of organic peat or muck.
2. The characteristics specified in the foregoing 310 CMR 10.57(2)(b)1. are critical to
the protection of the interests specified in 310 CMR 10.57(1)(b).
3. The boundary of Isolated Land Subject to Flooding is the perimeter of the largest
observed or recorded volume of water confined in said area.
In the event of a conflict of opinion regarding the extent of water confined in anIsolated Land Subject to Flooding, the applicant may submit an opinion certified by a
registered professional engineer, supported by engineering calculations, as to theprobable extent of said water. Said calculations shall be prepared in accordance with thegeneral requirements set forth in 310 CMR 10.57(2)(a)3.a. through c., except that themaximum extent of said water shall be based upon the total volume (rather than peakrate) of run-off from the drainage area contributing to the Isolated Land Subject toFlooding and shall be further based upon the assumption that there is no infiltration of
said run-off into the soil within the Isolated Land Subject to Flooding.4. The only portions of this resource area which shall be presumed to be vernal pool
habitat are those determined under procedures established in 310 CMR 10.57(2)(a)5.
5. The boundary of vernal pool habitat is that determined under procedures established
in 310 CMR 10.57(2)(a)6.
(3) Presumption. Where a project involves removing, filling, dredging or altering of Land
Subject to Flooding (both Bordering and Isolated Areas) the issuing authority shall presume that
such an area is significant to, and only to, the respective interests specified in 310 CMR
10.57(1)(a) and (b). This presumption may be overcome only upon a clear showing that said land
does not play a role in the protection of said interests. In the event that the presumption is
deemed to have been overcome, the issuing authority shall make a written determination to this
effect, setting forth its grounds (Form 6).
(4) General Performance Standards.
(a) Bordering Land Subject to Flooding:
1. Compensatory storage shall be provided for all flood storage volume that will be lost
as the result of a proposed project within Bordering Land Subject to Flooding, when in
the judgment of the issuing authority said loss will cause an increase or will contribute
incrementally to an increase in the horizontal extent and level of flood waters during peak
flows.
Compensatory storage shall mean a volume not previously used for flood storage and
shall be incrementally equal to the theoretical volume of flood water at each elevation,
up to and including the 100-year flood elevation, which would be displaced by the
proposed project. Such compensatory volume shall have an unrestricted hydraulic
connection to the same waterway or water body. Further, with respect to waterways,
such compensatory volume shall be provided within the same reach of the river, stream
or creek.
2. Work within Bordering Land Subject to Flooding, including that work required to
provide the above-specified compensatory storage, shall not restrict flows so as to cause
an increase in flood stage or velocity.
3. Work in those portions of bordering land subject to flooding found to be significant
to the protection of wildlife habitat shall not impair its capacity to provide important
wildlife habitat functions. Except for work which would adversely affect vernal pool
habitat, a project or projects on a single lot, for which Notice(s) of Intent is filed on or
after November 1, 1987, that (cumulatively) alter(s) up to 10% or 5,000 square feet
(whichever is less) of land in this resource area found to be significant to the protection
of wildlife habitat, shall not be deemed to impair its capacity to provide important
wildlife habitat functions. Additional alterations beyond the above threshold, or altering
vernal pool habitat, may be permitted if they will have no adverse effects on wildlife
habitat, as determined by procedures contained in 310 CMR 10.60.

(b) Isolated Land Subject to Flooding: A proposed project in Isolated Land Subject toFlooding shall not result in the following:
1. Flood damage due to filling which causes lateral displacement of water that wouldotherwise be confined within said area.
2. An adverse effect on public and private water supply or ground water supply, wheresaid area is underlain by pervious material.
3. An adverse effect on the capacity of said area to prevent pollution of the groundwater, where the area is underlain by pervious material which in turn is covered by a matof organic peat and muck.
4. An impairment of its capacity to provide wildlife habitat where said area is vernalpool habitat, as determined by procedures contained in 310 CMR 10.60.
(c) Protection of Rare Wildlife Species: Notwithstanding the provisions of 310 CMR10.57(4)(a) or (b), no project may be permitted which will have any adverse effect on
specified wildlife habitat sites of rare vertebrate or invertebrate species, as identified byprocedures established under 310 CMR 10.59.
10.58 Riverfront Area
(1) Preamble. Riverfront areas are likely to be significant to protect the private or public watersupply; to protect groundwater; to provide flood control; to prevent storm damage; to prevent
pollution; to protect land containing shellfish; to protect wildlife habitat; and to protect thefisheries. Land adjacent to rivers and streams can protect the natural integrity of these water
bodies. The presence of natural vegetation within riverfront areas is critical to sustaining riversas ecosystems and providing these public values. The riverfront area can prevent degradationof water quality by filtering sediments, toxic substances (such as heavy metals), and nutrients
(such as phosphorus and nitrogen) from stormwater, nonpoint pollution sources, and the riveritself. Sediments are trapped by vegetation before reaching the river. Nutrients and toxic
substances may be detained in plant root systems or broken down by soil bacteria. Riverfrontareas can trap and remove disease-causing bacteria that otherwise would reach rivers and coastal
estuaries where they can contaminate shellfish beds and prohibit safe human consumption.Natural vegetation within the riverfront area also maintains water quality for fish and wildlife.
Where rivers serve as water supplies or provide induced recharge to wells, the riverfront areacan be important to the maintenance of drinking water quality and quantity. Land along riversin its natural state with a high infiltration capacity increases the yield of a water supply well.
When riverfront areas lack the capacity to filter pollutants, contaminants can reach humanpopulations served by wells near rivers or by direct river intakes. The capacity of riverfront areas
to filter pollutants is equally critical to surface water supplies, reducing or eliminating the needfor additional treatment. In the watershed, mature vegetation within riverfront areas provides
shade to moderate water temperatures and slow algal growth, which can produce odors and tasteproblems in drinking water.
Within riverfront areas, surface water interaction with groundwater significantly influences
the stream ecosystem. The dynamic relationship between surface and groundwater within the“hyporheic zone” sustains communities of aquatic organisms which regulate the flux of nutrients,
biomass and the productivity of organisms including fish within the stream itself. The hyporheiczone extends to greater distances horizontally from the channel in large, higher order streams
with alluvial floodplains, but the interaction within this zone is important in smaller streams aswell.
By providing recharge and retaining natural flood storage, as well as by slowing surfacewater runoff, riverfront areas can mitigate flooding and damage from storms. The root systemsof riverfront vegetation keep soil porous, increasing infiltration capacity. Vegetation also
removes excess water through evaporation and transpiration. This removal of water from the soilallows for more infiltration when flooding occurs. Increases in storage of floodwaters can
decrease peak discharges and reduce storm damage. Vegetated riverfronts also dissipate theenergy of storm flows, reducing damage to public and private property.
Riverfront areas are critical to maintaining thriving fisheries. Maintaining vegetation alongrivers promotes fish cover, increases food and oxygen availability, decreases sedimentation, and
provides spawning habitat. Maintenance of water temperatures and depths is critical to manyimportant fish species. Where groundwater recharges surface water flows, loss of recharge asa result of impervious surfaces within the riverfront area may aggravate low flow conditions and
increase water temperatures. In some cases, summer stream flows are maintained almostexclusively from groundwater recharge. Small streams are most readily impacted by removal
of trees and other vegetation along the shore.
Wetland Regulations – May 2008 Page 93
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.58: continued
Riverfront areas are important wildlife habitat, providing food, shelter, breeding, migratory,
and overwintering areas. Even some predominantly upland species use and may be seasonally
dependent on riverfront areas. Riverfront areas promote biological diversity by providing
habitats for an unusually wide variety of upland and wetland species, including bald eagles,
osprey, and kingfishers. Large dead trees provide nesting sites for bird species that typically use
the same nest from year to year. Sandy areas along rivers may serve as nesting sites for turtles
and water snakes. Riverfront areas provide food for species such as wood turtles which feed and
nest in uplands but use rivers as resting and overwintering areas. Riverfront areas provide
corridors for the migration of wildlife for feeding or breeding. Loss of this connective function,
from activities that create barriers to wildlife movement within riverfront areas, results in habitat
fragmentation and causes declines in wildlife populations. Wildlife must also be able to moveacross riverfront areas, between uplands and the river.
Vernal pools are frequently found within depressions in riverfront areas. These pools areessential breeding sites for certain amphibians which require isolated, seasonally wet areaswithout predator fish. Most of these amphibians require areas of undisturbed woodlands ashabitat during the non-breeding seasons. Some species require continuous woody vegetationbetween woodland habitat and the breeding pools. Depending on the species, during non-breeding seasons these amphibians may remain near the pools or travel one-fourth mile or more
from the pools. Reptiles, especially turtles, often require areas along rivers to lay their eggs.Since amphibians and reptiles are less mobile than mammals and birds, maintaining integrity of
their habitat is critical.
In those portions so extensively altered by human activity that their important wildlife habitat
functions have been effectively eliminated, riverfront areas are not significant to the protection
of important wildlife habitat and vernal pool habitat.
(2) Definitions, Critical Characteristics and Boundaries.
(a) A Riverfront Area is the area of land between a river's mean annual high water line and
a parallel line measured horizontally. The riverfront area may include or overlap other
resource areas or their buffer zones. The riverfront area does not have a buffer zone.
1. A river is any natural flowing body of water that empties to any ocean, lake, pond,
or other river and which flows throughout the year. Rivers include streams (see 310
CMR 10.04: Stream) that are perennial because surface water flows within them
throughout the year. Intermittent streams are not rivers as defined herein because surface
water does not flow within them throughout the year. When surface water is not flowing
within an intermittent stream, it may remain in isolated pools or it may be absent. When
surface water is present in contiguous and connected pool/riffle systems, it shall be
determined to be flowing. Rivers begin at the point an intermittent stream becomes
perennial or at the point a perennial stream flows from a spring, pond, or lake.
Downstream of the first point of perennial flow, a stream normally remains a river except
where interrupted by a lake or pond. Upstream of the first point of perennial flow, a
stream is normally intermittent.
a. A river or stream shown as perennial on the current United States Geological
Survey (USGS) or more recent map provided by the Department is perennial.
b. A river or stream shown as intermittent or not shown on the current USGS map
or more recent map provided by the Department, that has a watershed size greater
than or equal to one square mile, is perennial.
c. A stream shown as intermittent or not shown on the current USGS map or more
recent map provided by the Department, that has a watershed size less than one
square mile, is intermittent unless:
i. The stream has a watershed size of at least one-half (0.50) square mile and has
a predicted flow rate greater than or equal to 0.01 cubic feet per second at the
99% flow duration using the USGS Stream Stats method. The issuing authority
shall find such streams to be perennial; or
Wetland Regulations – May 2008 Page 94
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.58: continued
ii. When the USGS StreamStats method cannot be used because the stream doesnot have a mapped and digitized centerline (including but not limited to streams
located in the following basins: North Coastal Basin, Taunton Basin, BuzzardsBay Basin, Cape Cod and Islands Basin, and that portion of the South Coastal
Basin that is south of the Jones River sub-basin), and the stream has a watershedsize of at least one-half (0.50) square mile, and the surficial geology of the
contributing drainage area to the stream at the project site contains 75% or morestratified drift, the issuing authority shall find such streams to be perennial.Stratified drift shall mean sand and gravel deposits that have been layered and
sorted by glacial meltwater streams. Areal percentages of stratified drift may bedetermined using USGS surficial geologic maps, USGS Hydrological Atlases,
Massachusetts Geographical Information System (MassGIS) surficial geologydata layer, or other published or electronic surficial geological information from
a credible source.d. Notwithstanding 310 CMR 10.58(2)(a)1.a. through c., the issuing authority shallfind that any stream is intermittent based upon a documented field observation that
the stream is not flowing. A documented field observation shall be made by acompetent source and shall be based upon an observation made at least once per day,
over four days in any consecutive 12 month period, during a non-drought period ona stream not significantly affected by drawdown from withdrawals of water supply
wells, direct withdrawals, impoundments, or other man-made flow reductions ordiversions. Field observations made after December 20, 2002 shall be documented
by field notes and by dated photographs or video. Field observations made prior toDecember 20, 2002 shall be documented by credible evidence. All field observationsshall be submitted to the issuing authority with a statement signed under the penalties
of perjury attesting to the authenticity and veracity of the field notes, photographsor video and other credible evidence. Department staff, conservation commissioners,
and conservation commission staff are competent sources; issuing authorities mayconsider evidence from other sources that are determined to be competent.
e. Rivers include the entire length and width to the mean annual high-water line ofthe major rivers (Assabet, Blackstone, Charles, Chicopee, Concord, Connecticut,
Deerfield, Farmington, French, Hoosic, Housatonic, Ipswich, Merrimack, Millers,Nashua, Neponset, Parker (Essex County), Quinebaug, Shawsheen, Sudbury,Taunton, Ten Mile, and Westfield).
f. Rivers include perennial streams that cease to flow during periods of extendeddrought. Periods of extended drought for purposes of 310 CMR 10.00 shall be those
periods, in those specifically identified geographic locations, determined to be at the“Advisory” or more severe drought level by the Massachusetts Drought Managment
Task Force, as established by the Executive Office of Environmental Affairs and theMassachusetts Emergency Management Agency in 2001, in accordance with theMassachusetts Drought Management Plan (MDMP). Rivers and streams that are
perennial under natural conditions but are significantly affected by drawdown fromwithdrawals of water supply wells, direct withdrawals, impoundments, or other man-
made flow reductions or diversions shall be considered perennial.g. Manmade canals (e.g., the Cape Cod Canal and canals diverted from rivers in
Lowell and Holyoke) and mosquito ditches associated with coastal rivers do not haveriverfront areas.
h. Where rivers flow through lakes or ponds, the riverfront area stops at the inlet andbegins again at the outlet. A water body identified as a lake, pond, or reservoir on thecurrent U.S.G.S. map or more recent map provided by the Department, is a lake or
pond, unless the issuing authority determines that the water body has primarilyriverine characteristics. When a water body is not identified as a lake, pond, or
reservoir on the current U.S.G.S. map or more recent map provided by theDepartment, the water body is a river if it has primarily riverine characteristics.
Riverine characteristics may include, but are not limited to, unidirectional flow thatcan be visually observed or measured in the field. In addition, rivers are
characterized by horizontal zonation as opposed to the vertical stratification that istypically associated with lakes and ponds. Great Ponds (i.e., any pond whichcontained more than ten acres in its natural state, as calculated based on the surface
area of lands lying below the natural high water mark; a list is available from theDepartment) are never rivers.

2. Mean Annual High-Water Line of a river is the line that is apparent from visiblemarkings or changes in the character of soils or vegetation due to the prolonged presence
of water and that distinguishes between predominantly aquatic and predominantlyterrestrial land. Field indicators of bankfull conditions shall be used to determine the
mean annual high-water line. Bankfull field indicators include but are not limited to:changes in slope, changes in vegetation, stain lines, top of pointbars, changes in bank
materials, or bank undercuts.a. In most rivers, the first observable break in slope is coincident with bankfullconditions and the mean annual high-water line.
b. In some river reaches, the mean annual high-water line is represented by bankfullfield indicators that occur above the first observable break in slope, or if no
observable break in slope exists, by other bankfull field indicators. These riverreaches are characterized by at least two of the following features: low gradient,
meanders, oxbows, histosols, a low-flow channel, or poorly-defined or nonexistentbanks. c. In tidal rivers, the mean annual high-water line is coincident with the mean high
water line determined under 310 CMR 10.23.3. The Riverfront Area is the area of land between a river's mean annual high-water line
measured horizontally outward from the river and a parallel line located 200 feet away,except that the parallel line is located:
a. 25 feet away in Boston, Brockton, Cambridge, Chelsea, Everett, Fall River,Lawrence, Lowell, Malden, New Bedford, Somerville, Springfield, Winthrop, and
Worcester; b. 25 feet away in densely developed areas, as designated by the Secretary of theExecutive Office of Energy and Environmental Affairs pursuant to 301 CMR 10.00;
andc. 100 feet away for new agricultural and aquacultural activities.
Measured horizontally means that the riverfront area extends at a right angle to themean annual high-water line rather than along the surface of the land.
Where a river runs through a culvert more than 200 feet in length, the riverfront areastops at a perpendicular line at the upstream end of the culvert and resumes at the
downstream end. When a river contains islands, the riverfront area extends landwardinto the island from and parallel to the mean annual high-water line.(b) The physical characteristics of a Riverfront Area as described in 310 CMR 10.58(2)(a)
are critical to the protection of the interests specified in 310 CMR 10.58(1).(c) The boundary of the Riverfront Area is a line parallel to the mean annual high-water
line, located at the outside edge of the riverfront area. At the point where a stream becomesperennial, the riverfront area begins at a line drawn as a semicircle with a 200 foot (25 foot
in densely developed areas; 100 foot for new agriculture) radius around the point andconnects to the parallel line perpendicular to the mean annual high-water line which formsthe outer boundary. When a river flows into coastal waters or an embayment, the river shall
end at the mouth of coastal river line as delineated on the current mouth of coastal river mapseries maintained by the Department, subject to revisions after public notice and referred to
as the Massachusetts Mouth of Coastal River Maps. If a mouth of coastal river line is notdelineated on the current map series, the issuing authority shall determine the mouth of
coastal river line in accordance with the Department’s most current Mouth of Coastal RiverPolicy. A mouth of coastal river line shown on the Department’s mouth of coastal river map
series is not evidence that a stream is perennial; such a determination shall only be madepursuant to 310 CMR 10.58(2)(a)1.
(3) Presumption. Where a proposed activity involves work within the riverfront area, theissuing authority shall presume that the area is significant to protect the private or public water
supply; to protect the groundwater; to provide flood control; to prevent storm damage; to preventpollution; to protect land containing shellfish; to protect wildlife habitat; and to protect fisheries.
The presumption is rebuttable and may be overcome by a clear showing that the riverfrontarea does not play a role in the protection of one or more of these interests. In the event that the
presumption is deemed to have been overcome as to the protection of all the interests, the issuingauthority shall make a written determination to this effect, setting forth its grounds on Form 6.Where the applicant provides information that the riverfront area at the site of the activity does
not play a role in the protection of an interest, the issuing authority may determine that thepresumption for that interest has been rebutted and the presumption of significance is partially
overcome.
Wetland Regulations – May 2008 Page 96
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.58: continued
(4) General Performance Standard. Where the presumption set forth in 310 CMR 10.58(3) is
not overcome, the applicant shall prove by a preponderance of the evidence that there are no
practicable and substantially equivalent economic alternatives to the proposed project with less
adverse effects on the interests identified in M.G.L. c.131 § 40 and that the work, including
proposed mitigation, will have no significant adverse impact on the riverfront area to protect the
interests identified in M.G.L. c. 131 § 40. In the event that the presumption is partially
overcome, the issuing authority shall make a written determination setting forth its grounds in
the Order of Conditions and the partial rebuttal shall be taken into account in the application of
310 CMR 10.58 (4)(d)1.a. and c.; the issuing authority shall impose conditions in the Order that
contribute to the protection of interests for which the riverfront area is significant.
(a) Protection of Other Resource Areas. The work shall meet the performance standardsfor all other resource areas within the riverfront area, as identified in 310 CMR 10.30 (coastal
bank), 10.32 (salt marsh), 10.55 (Bordering Vegetated Wetland), and 10.57 (Land Subjectto Flooding). When work in the riverfront area is also within the buffer zone to anotherresource area, the performance standards for the riverfront area shall contribute to theprotection of the interests of M.G.L. c. 131, § 40 in lieu of any additional requirements that
might otherwise be imposed on work in the buffer zone within the riverfront area.(b) Protection of Rare Species. No project may be permitted within the riverfront area
which will have any adverse effect on specified habitat sites of rare wetland or upland,vertebrate or invertebrate species, as identified by the procedures established under 310 CMR
10.59 or 10.37, or which will have any adverse effect on vernal pool habitat certified prior
to the filing of the Notice of Intent.
(c) Practicable and Substantially Equivalent Economic Alternatives. There must be no
practicable and substantially equivalent economic alternative to the proposed project with
less adverse effects on the interests identified in M.G.L. c. 131 § 40.
1. Definition of Practicable. An alternative is practicable and substantially equivalent
economically if it is available and capable of being done after taking into consideration
costs, existing technology, proposed use, and logistics, in light of overall project
purposes. Available and capable of being done means the alternative is obtainable and
feasible. Project purposes shall be defined generally (e.g., single family home,
residential subdivision, expansion of a commercial development). The alternatives
analysis may reduce the scale of the activity or the number of lots available for
development, consistent with the project purpose and proposed use. The alternatives
analysis shall not include interior design specifications (i.e., neither the proposed use or
project purpose in the Notice of Intent nor the Order of Conditions should specify the
number of rooms, bedrooms, etc. within a building). Transactions shall not be arranged
to circumvent the intent of alternatives analysis review. The four factors to be considered
are:

10.58: continued
a. Costs, and whether such costs are reasonable or prohibitive to the owner. The
owner means the individual or entity which owns the area where the activity will
occur or which will implement the project purpose. Cost includes expenditures for
a project within the riverfront area, such as land acquisition, site preparation, design,
construction, landscaping, and transaction expenses. Cost does not include
anticipated profits after the project purpose is achieved or expenditures to achieve the
project purpose prior to receiving an Order with the exception of land acquisition
costs incurred prior to August 7, 1996. In taking costs into account, the issuing
authority shall be guided by these principles:
i. The cost of an alternative must be reasonable for the project purpose, and
cannot be prohibitive.ii. Higher or lower costs taken alone will not determine whether an alternative
is practicable. An alternative for proposed work in the riverfront area must be apracticable and substantially equivalent economic alternative (i.e., will achievethe proposed use and project purpose from an economic perspective).iii. In considering the costs to the owner, the evaluation should focus on thefinancial capability reasonably expected from the type of owner (e.g., individualhomeowner, residential developer, small business owner, large commercial or
industrial developer) rather than the personal or corporate financial status of thatparticular owner. Applicants should not submit, nor should issuing authorities
request, financial information of a confidential nature, such as income tax records
or bank statements.
iv. Issuing authorities may require documentation of costs, but may also base
their determinations on descriptions of alternatives, knowledge of alternative
sites, information provided by qualified professionals, comparisons to costs
normally associated with similar projects, or other evidence. Any documentation
of costs should be limited to that required for a determination of whether the
costs are reasonable or prohibitive.
b. Existing technology, which includes best available measures (i.e., the most up-to-
date technology or the best designs, measures, or engineering practices that have been
developed and are commercially available);
c. The proposed use. This term is related to the concept of project purpose. In the
context of typical single family homes, the project purpose (construction of a single
family house) and proposed use (family home) are virtually identical. In the context
of projects where the purpose implies a business component, such as residential
subdivision, commercial, and industrial projects, the proposed use typically requires
economic viability. Practicable and substantially equivalent economic alternatives
include alternatives which are economically viable for the proposed use from the
perspective of site location, project configuration within a site, and the scope of the
project. In the context of publically financed projects, the proposed use includes
consideration of legitimate governmental purposes (e.g., protection of health and
safety, providing economic development opportunities, or similiar public purposes.);
and
d. Logistics. Logistics refers to the presence or absence of physical or legal
constraints. Physical characteristics of a site may influence its development. Legal
barriers include circumstances where a project cannot meet other applicable
requirements to obtain the necessary permits at an alternative site. An alternative site
is not practicable if special legislation or changes to municipal zoning would be
required to achieve the proposed use or project purpose. An alternative is not
practicable if the applicant is unable to obtain the consent of the owner of an
alternative site for access for the purpose of obtaining the information required by the
Notice of Intent or of allowing the issuing authority to conduct a site visit.
2. Scope of Alternatives. The scope of alternatives under consideration shall be
commensurate with the type and size of the project. The issuing authority shall presume
that alternatives beyond the scope described below are not practicable and therefore need
not be considered. The issuing authority or another party may overcome the presumption
by demonstrating the practicability of a wider range of alternatives, based on cost, and
whether the cost is reasonable or prohibitive to the owner; existing technology; proposed
use; and logistics in light of the overall project purpose.

a. The area under consideration for practicable alternatives is limited to the lot for
activities associated with the construction or expansion of a single family house on
a lot recorded on or before August 1, 1996.
b. The area under consideration for practicable alternatives is limited to the lot, the
subdivided lots and any adjacent lots formerly or presently owned by the same owner
for:
i. activities associated with the construction or expansion of a single family
house on a lot recorded after August 1, 1996;
ii. any expansion of an existing structure, including enlargement of the footprint
of any structure or the addition of associated structures for single family homes
(e.g., a garage) on lots recorded after August 1, 1996; iii. any activity other than the construction or expansion of a single family house
where the applicant owned the lot before August 7, 1996, including the creationof a real estate subdivision but excluding public projects, and the applicant willimplement the project purpose;iv. new agriculture or aquaculture projects;v. any activity by a public entity when funds for the purchase of the site for theproject purpose have been appropriated through action of the appropriate
municipal board or state agency prior to the August 7, 1996; or vi. any lot shown on a definitive subdivision plan approved under M.G.L. c. 41,
§§ 81K to 81GG, provided there is a recorded deed restriction limiting the total
alteration to 5000 square feet or 10%, whichever is greater, of the riverfront area
allocated to the lots within the entire subdivision.
c. Except as allowed under 310 CMR 10.58(4)(c)2.b., the area under consideration
for practicable alternatives extends to the original parcel and the subdivided parcels,
any adjacent parcels, and any other land which can reasonably be obtained within the
municipality for:
i. activities associated with residential subdivision or housing complexes,
institutional, industrial, or commercial projects; or
ii. activities conducted by municipal government.
For adjacent lots, reasonably be obtained means to purchase at market prices if
otherwise practicable, as documented by offers (and any responses). For other land,
reasonably be obtained means adequate in size to accommodate the project purpose
and listed for sale within appropriately zoned areas, at the time of filing a Request for
Determination or Notice of Intent, within the municipality.
d. Alternatives extend to any sites which can reasonably be obtained within the
appropriate region of the state for:
i. residential, institutional, commercial, or industrial activities required to
evaluate off-site alternatives in more than one municipality in an Environmental
Impact Report under M.G.L. c. 30, §§ 61 through 62H, or an alternatives analysis
conducted by the Corps of Engineers for a Section 404 permit under the federal
Clean Water Act, 33 U.S.C. 1251 et seq., and used for 401 Water Quality
Certification under 314 CMR 9.00; or
ii. activities conducted by district, county, state or federal government entities.
The area to be considered is the service area within the governmental unit
boundary or jurisdictional authority, or the municipality if there is no defined
service area, consistent with the project purpose.
3. Evaluation of Alternatives. The applicant shall demonstrate that there are no
practicable and substantially equivalent economic alternatives as defined in 310 CMR
10.58(4)(c)1., within the scope of alternatives as set forth in 310 CMR 10.58(4)(c)2.,
with less adverse effects on the interests identified in M.G.L. c. 131 § 40. The applicant
shall submit information to describe sites and the work both for the proposed location
and alternative site locations and configurations sufficient for a determination by the
issuing authority under 310 CMR 10.58(4)(d). The level of detail of information shall
be commensurate with the scope of the project and the practicability of alternatives.
Where an applicant identifies an alternative which can be summarily demonstrated to be
not practicable, an evaluation is not required.
Wetland Regulations – May 2008 Page 100
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.58: continued
The purpose of evaluating project alternatives is to locate activities so that impacts
to the riverfront area are avoided to the extent practicable. Projects within the scope of
alternatives must be evaluated to determine whether any are practicable. As much of a
project as feasible shall be sited outside the riverfront area. If siting of a project entirely
outside the riverfront area is not practicable, the alternatives shall be evaluated to locate
the project as far as possible from the river.
The issuing authority shall not require alternatives which result in greater or
substantially equivalent adverse impacts. If an alternative would result in no identifiable
difference in impact, the issuing authority shall eliminate the alternative. If there would
be no less adverse effects on the interests identified in M.G.L. c. 131, § 40, the proposed
project rather than a practicable alternative shall be allowed, but the criteria in 310 CMR10.58(4)(d) for determining no significant adverse impact must still be met. If there is
a practicable and substantially equivalent economic alternative with less adverse effects,the proposed work shall be denied and the applicant may either withdraw the Notice ofIntent or receive an Order of Conditions for the alternative, provided the applicantsubmitted sufficient information on the alternative in the Notice of Intent.(d) No Significant Adverse Impact. The work, including proposed mitigation measures,must have no significant adverse impact on the riverfront area to protect the interests
identified in M.G.L. c. 131, § 40.
1. Within 200 foot riverfront areas, the issuing authority may allow the alteration of up
to 5000 square feet or 10% of the riverfront area within the lot, whichever is greater, on
a lot recorded on or before October 6, 1997 or lots recorded after October 6, 1997 subject
to the restrictions of 310 CMR 10.58(4)(c)2.b.vi., or up to 10% of the riverfront area
within a lot recorded after October 6, 1997, provided that:
a. At a minimum, a 100 foot wide area of undisturbed vegetation is provided. This
area shall extend from mean annual high-water along the river unless another location
would better protect the interests identified in M.G.L. c. 131 § 40. If there is not a
100 foot wide area of undisturbed vegetation within the riverfront area, existing
vegetative cover shall be preserved or extended to the maximum extent feasible to
approximate a 100 foot wide corridor of natural vegetation. Replication and
compensatory storage required to meet other resource area performance standards are
allowed within this area; structural stormwater management measures may be
allowed only when there is no practicable alternative. Temporary impacts where
necessary for installation of linear site-related utilities are allowed, provided the area
is restored to its natural conditions. Proposed work which does not meet the
requirement of 310 CMR 10.58(4)(d)1.a. may be allowed only if an applicant
demonstrates by a preponderance of evidence from a competent source that an area
of undisturbed vegetation with an overall average width of 100 feet will provide
equivalent protection of the riverfront area, or that a partial rebuttal of the
presumptions of significance is sufficient to justify a lesser area of undisturbed
vegetation;
b. Stormwater is managed according to standards established by the Department in
its Stormwater Policy.
c. Proposed work does not impair the capacity of the riverfront area to provide
important wildlife habitat functions. Work shall not result in an impairment of the
capacity to provide vernal pool habitat identified by evidence from a competent
source, but not yet certified. For work within an undeveloped riverfront area which
exceeds 5,000 square feet, the issuing authority may require a wildlife habitat
evaluation study under 310 CMR 10.60.
d. Proposed work shall not impair groundwater or surface water quality by
incorporating erosion and sedimentation controls and other measures to attenuate
nonpoint source pollution.
The calculation of square footage of alteration shall exclude areas of replication or
compensatory flood storage required to meet performance standards for other resource
areas, or any area of restoration within the riverfront area. The calculation also shall
exclude areas used for structural stormwater management measures, provided there is no
practicable alternative to siting these structures within the riverfront area and provided
a wildlife corridor is maintained (e.g. detention basins shall not be fenced).
2. Within 25 foot riverfront areas, any proposed work shall cause no significant adverse
impact by:
Wetland Regulations – May 2008 Page 101
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.58: continued
a. Limiting alteration to the maximum extent feasible, and at a minimum, preserving
or establishing a corridor of undisturbed vegetation of a maximum feasible width.Replication and compensatory storage required to meet other resource area
performance standards are allowed within this area; structural stormwater
management measures shall be allowed only when there is no practicable alternative;b. Providing stormwater management according to standards established by the
Department;
c. Preserving the capacity of the riverfront area to provide important wildlife habitatfunctions. Work shall not result in an impairment of the capacity to provide vernal
pool habitat when identified by evidence from a competent source but not yet
certified; andd. Proposed work shall not impair groundwater or surface water quality byincorporating erosion and sedimentation controls and other measures to attenuate
nonpoint source pollution.3. Notwithstanding the provisions of 310 CMR10.58(4)(d)1. or 2., the issuing authorityshall allow the construction of a single family house, a septic system if no sewer is
available, and a driveway, on a lot recorded before August 7, 1996 where the size orshape of the lot within the riverfront area prevents the construction from meeting therequirements of 310 CMR 10.58(4)(d)1. or 2., provided that:
a. The lot can be developed for such purposes under the applicable provisions of
other municipal and state law; andb. The performance standards of 310 CMR 10.58(4)(d) are met to the maximum
extent feasible. In difficult siting situations, the maximum extent of yards around
houses should be limited to the area necessary for construction. Except where the lotcontains vernal pool habitat or specified habitat sites of rare species, a wildlife habitat
evaluation study shall not be required.
4. Notwithstanding the provisions of 310 CMR 10.58(4)(d)1. or 2., the issuing authoritymay allow the construction of a commercial structure of minimum feasible dimension,
on a lot recorded before August 7, 1996 where the size or shape of the lot within the
riverfront area prevents the construction from meeting the requirements of 310 CMR10.58(4)(d)1. or 2., only if:
a. The lot can be developed for such purposes and cannot be developed for any other
purposes under the applicable provisions of other municipal and state law; b. The work is not eligible for 310 CMR 10.58(5); and
c. The performance standards of 310 CMR 10.58(4)(d)1. or 2. are met to the
maximum extent feasible.
(5) Redevelopment Within Previously Developed Riverfront Areas; Restoration and Mitigation.
Notwithstanding the provisions of 310 CMR 10.58(4)(c) and (d), the issuing authority may allowwork to redevelop a previously developed riverfront area, provided the proposed work improvesexisting conditions. Redevelopment means replacement, rehabilitation or expansion of existing
structures, improvement of existing roads, or reuse of degraded or previously developed areas.A previously developed riverfront area contains areas degraded prior to August 7, 1996 byimpervious surfaces from existing structures or pavement, absence of topsoil, junkyards, or
abandoned dumping grounds. Work to redevelop previously developed riverfront areas shall
conform to the following criteria:(a) At a minimum, proposed work shall result in an improvement over existing conditions
of the capacity of the riverfront area to protect the interests identified in M.G.L. c. 131 § 40.
When a lot is previously developed but no portion of the riverfront area is degraded, therequirements of 310 CMR 10.58(4) shall be met.
(b) Stormwater management is provided according to standards established by the
Department.(c) Within 200 foot riverfront areas, proposed work shall not be located closer to the river
than existing conditions or 100 feet, whichever is less, or not closer than existing conditions
within 25 foot riverfront areas, except in accordance with 310 CMR 10.58(5)(f) or (g). (d) Proposed work, including expansion of existing structures, shall be located outside the
riverfront area or toward the riverfront area boundary and away from the river, except in
accordance with 310 CMR 10.58(5)(f) or (g).(e) The area of proposed work shall not exceed the amount of degraded area, provided that
the proposed work may alter up to 10% if the degraded area is less than 10% of the riverfront
area, except in accordance with 310 CMR 10.58(5)(f) or (g).

(f) When an applicant proposes restoration on-site of degraded riverfront area, alteration
may be allowed notwithstanding the criteria of 310 CMR 10.58(5)(c), (d), and (e) at a ratio
in square feet of at least 1:1 of restored area to area of alteration not conforming to the
criteria. Areas immediately along the river shall be selected for restoration. Alteration not
conforming to the criteria shall begin at the riverfront area boundary. Restoration shall
include:
1. removal of all debris, but retaining any trees or other mature vegetation;
2. grading to a topography which reduces runoff and increases infiltration;
3. coverage by topsoil at a depth consistent with natural conditions at the site; and
4. seeding and planting with an erosion control seed mixture, followed by plantings of
herbaceous and woody species appropriate to the site;
(g) When an applicant proposes mitigation either on-site or in the riverfront area within the
same general area of the river basin, alteration may be allowed notwithstanding the criteria
of 310 CMR 10.58(5)(c), (d), or (e) at a ratio in square feet of at least 2:1 of mitigation area
to area of alteration not conforming to the criteria or an equivalent level of environmental
protection where square footage is not a relevant measure. Alteration not conforming to the
criteria shall begin at the riverfront area boundary. Mitigation may include off-site
restoration of riverfront areas, conservation restrictions under M.G.L. c. 184, §§ 31 to 33 to
preserve undisturbed riverfront areas that could be otherwise altered under 310 CMR 10.00,
the purchase of development rights within the riverfront area, the restoration of bordering
vegetated wetland, projects to remedy an existing adverse impact on the interests identified
in M.G.L. c. 131, § 40 for which the applicant is not legally responsible, or similar activities
undertaken voluntarily by the applicant which will support a determination by the issuing
authority of no significant adverse impact. Preference shall be given to potential mitigation
projects, if any, identified in a River Basin Plan approved by the Secretary of the Executive
Office of Environmental Affairs.
(h) The issuing authority shall include a continuing condition in the Certificate of
Compliance for projects under 310 CMR 10.58(5)(f) or (g) prohibiting further alteration
within the restoration or mitigation area, except as may be required to maintain the area in
its restored or mitigated condition. Prior to requesting the issuance of the Certificate of
Compliance, the applicant shall demonstrate the restoration or mitigation has been
successfully completed for at least two growing seasons.
(6) Notwithstanding the Provisions of 310 CMR 10.58(1) through (5), Certain Activities or
Areas are Grandfathered or Exempted from Requirements for the Riverfront Area:
(a) Any excavation, structure, road, clearing, driveway, landscaping, utility line, rail line,
airport owned by a political subdivision, marine cargo terminal owned by a political
subdivision, bridge over two miles long, septic system, or parking lot within the riverfront
area in existence on August 7, 1996. Maintenance of such structures or areas is allowed
(including any activity which maintains a structure, roads (limited to repairs, resurfacing,
repaving, but not enlargement), clearing, landscaping, etc. in its existing condition) without
the filing of a Notice of Intent for work within the riverfront area, but not when such work
is within other resource areas or their buffer zones except as provided in 310 CMR
10.58(6)(b). Changes in existing conditions which will remove, fill, dredge or alter the
riverfront area are subject to 310 CMR 10.58, except that the replacement within the same
footprint of structures destroyed by fire or other casualty is not subject to 310 CMR 10.58.
(b) Certain minor activities as identified in 310 CMR 10.02(2)(b)1.
(c) On-site sewage disposal systems in existence on August 7, 1996 and the repair or
upgrade of existing systems in compliance with 310 CMR 15.000. New construction of a
system under 310 CMR 15.000 must comply with 310 CMR 10.58, subject to the
presumption for the siting of systems in 310 CMR 10.03.
(d) The expansion of structures, airports, and marine cargo terminals, provided they are
owned by a political subdivision and the expansion activity was physically begun on or
before November 1, 1996.
(e) Projects for which a draft environmental impact report was prepared and submitted
pursuant to M.G.L. c. 30, § 62B, on or before November 1, 1996, or as extended by the
Department for just cause but no later than December 31, 1996.

10.58: continued
(f) Projects for which a building permit conforming to local requirements was filed on or
before October 1, 1996 and granted on or before April 1, 1997, or as extended by the
conservation commission for just cause by no more than 60 days.
(g) The road and infrastructure shown on a definitive subdivision plan approved or endorsed
under M.G.L. c. 41, § 81U, on or before August 1, 1996. Activities on the subdivided lots
are subject to 310 CMR 10.58 unless they received a building permit under 310 CMR
10.58(6)(f).
(h) Construction, expansion, repair, restoration, alteration, replacement, operation and
maintenance of public or private local or regional wastewater treatment plants and their
related structures, conveyance systems, and facilities, including utility lines.
(i) Structures and activities subject to a M.G.L. c. 91 waterways license or permit, or
authorized prior to 1973 by a special act, are exempt, provided the structure or activity is
subject to jurisdiction and obtains a license, permit, or authorization under 310 CMR 9.00.
(j) Activities within riverfront areas subject to a protective order under M.G.L. c. 21, § 17B,
the Scenic Rivers Act.
(k) Activities on land occupied by historic mill complexes.
10.59: Estimated Habitats of Rare Wildlife (for inland wetlands)
If a project is within estimated habitat which is indicated on the most recent Estimated
Habitat Map of State-Listed Rare Wetlands Wildlife (if any) published by the Natural Heritage
and Endangered Species Program (hereinafter referred to as the Program), a fully completed copy
of the Notice of Intent (including all plans, reports, and other materials required under 310 CMR
10.05(4)(a) & (b)) for such project shall be sent to the Program via the U.S. Postal Service by
express or priority mail (or otherwise sent in a manner that guarantees delivery within two days).
Such copy shall be sent no later than the date of the filing of the Notice of Intent with the issuing
authority. Proof of timely mailing or other delivery to the Program of the copy of such Notice
of Intent shall be included in the Notice of Intent which is submitted to the issuing authority and
sent to the Department's regional office.
Estimated Habitat Maps shall be based on the estimated geographical extent of the habitats
of all state-listed vertebrate and invertebrate animal species for which a reported occurrence
within the last 25 years has been accepted by the Program and incorporated into its official data
base.
Wetland Regulations – May 2008 Page 104
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.59: continued
Within 30 days of the filing of such a Notice of Intent with the issuing authority the Program
shall determine whether any state-listed species identified on the aforementioned map are likelyto continue to be located on or near the site of the original occurrence and, if so, whether the area
to be altered by the proposed project is in fact part of such species' habitat. Such determination
shall be presumed by the issuing authority to be correct. Any proposed project which would altera resource area that is not located on the most recent Estimated Habitat Map (if any) provided
to the conservation commission, shall be presumed not to be within a rare species' habitat. Both
of these presumptions are rebuttable and may be overcome upon a clear showing to the contrary.If the issuing authority fails to receive a response from the Program within 30 days of the filing
of such a Notice of Intent, a copy of which was received by the Program in a timely manner, it
shall issue its Order of Conditions based on available information; however, the fact that aproposed project would alter a resource area that is located on an Estimated Habitat Map shallnot be considered sufficient evidence in itself that such project is in fact within the habitat of a
rare species.If the Program determines that a resource area which would be altered by a proposed projectis in fact within the habitat of a state-listed species, it shall provide in writing to the applicant and
to the Conservation Commission and the Department, the identification of the species whosehabitat would be altered by the proposed project, and all other relevant information which theProgram has regarding the species' location and habitat requirements, insofar as such information
may assist the applicant and the issuing authority to determine whether the project is or can be
designed so as to meet the performance standard set in 310 CMR 10.59.Notwithstanding 310 CMR 10.53 through 10.58 and 310 CMR 10.60, if a proposed project
is found by the issuing authority to alter a resource area which is part of the habitat of a
state-listed species, such project shall not be permitted to have any short or long term adverseeffects on the habitat of the local population of that species. A determination of whether or not
a proposed project will have such an adverse effect shall be made by the issuing authority.
However, a written opinion of the Program on whether or not a proposed project will have suchan adverse effect shall be presumed by the issuing authority to be correct. This presumption is
rebuttable and may be overcome upon a clear showing to the contrary.
The conservation commission shall not issue an Order of Conditions under 310 CMR10.05(6) regarding any such project for at least 30 days after the filing of the Notice of Intent
unless the Program before such time period has elapsed has either determined that the resource
area(s) which would be altered by the project is not in fact within the habitat of a state-listedspecies or, if it has determined that such resource area(s) is in fact within rare species habitat,
rendered a written opinion as to whether the project will have an adverse effect on that habitat.
Notwithstanding any other provision of 310 CMR 10.58, should an Environmental ImpactReport be required for a proposed project under the M.G.L. c. 30, §§ 6 through 62H, asdetermined by 301 CMR 11.00 the performance standard established under 310 CMR 10.58 shall
only apply to proposed projects which would alter the habitat of a rare species for which anoccurrence has been entered into the official data base of the Massachusetts Natural Heritage andEndangered Species Program prior to the time that the Secretary of the Executive Office of
Environmental Affairs has determined, in accordance with the provisions of 301 CMR 11.09(4),that a final Environmental Impact Report for that project adequately and properly complies withthe M.G.L. c. 30, §§ 6 through 62H (unless, subsequent to that determination, the Secretary
requires supplemental information concerning state-listed species, in accordance with the
provisions of 301 CMR 11.17).
10.60: Wildlife Habitat Evaluations
(1) Measuring Adverse Effects on Wildlife Habitat
(a) To the extent that a proposed project on inland Banks, Land Under Water, Riverfront
Area, or Land Subject to Flooding will alter vernal pool habitat or will alter other wildlifehabitat beyond the thresholds permitted under 310 CMR 10.54(4)(a)5., 10.56(4)(a)4.,
10.57(4)(a)3. and 10.58(4)(d)1., such alterations may be permitted only if they will have no
adverse effects on wildlife habitat. Adverse effects on wildlife habitat mean the alterationof any habitat characteristic listed in 310 CMR 10.60(2), insofar as such alteration will,
following two growing seasons of project completion and thereafter (or, if a project would
eliminate trees, upon the maturity of replanted saplings) substantially reduce its capacity toprovide the important wildlife habitat functions listed in 310 CMR 10.60(2). Such
performance standard, however, shall not apply to the habitat of rare species, which are
covered by the performance standards established under 310 CMR 10.59.
Wetland Regulations – May 2008 Page 105
310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.60: continued
(b) An evaluation by the applicant of whether a proposed project will have an adverse effect
on wildlife habitat beyond permissable thesholds shall be performed by an individual with
at least a masters degree in wildlife biology or ecological science from an accredited college
or university, or other competent professional with at least two years experience in wildlife
habitat evaluation.
(c) Any wildlife habitat management practices conducted by the Division of Fisheries and
Wildlife, and any wildlife management practices of any individual or organization if
reviewed and approved in writing by said Division, shall be presumed to have no adverse
effect on wildlife habitat. Such presumption is rebuttable, and may be overcome by a clear
showing to the contrary.
(2) Wildlife Habitat Characteristics of Inland Resource Areas:
(a) Banks. The topography, soil structure, and plant community composition and structure
of banks can provide the following important wildlife habitat functions:
1. Food, shelter and migratory and breeding areas for wildlife
2. Overwintering areas for mammals and reptiles.
(b) Land Under Water Bodies or Waterways. The plant community and soil composition
and structure, hydrologic regime, topography and water quality of land under water bodies
or waterways can provide the following important wildlife habitat functions:
1. Food, shelter and breeding areas for wildlife;
2. Overwintering areas for mammals, reptiles and amphibians.
(c) Vernal Pool Habitat. The topography, soil structure, plant community composition and
structure, and hydrologic regime of vernal pool habitat can provide the following important
wildlife habitat functions:
1. Food, shelter, migratory and breeding areas, and overwintering areas for amphibians;
2. Food for other wildlife.
(d) Lower Floodplains. The hydrologic regime, plant community and soil composition and
structure, topography, and proximity to water bodies and waterways of lower floodplains can
provide the following important wildlife habitat functions:
1. Food, shelter, migratory and overwintering areas for wildlife;
2. Breeding areas for birds, mammals and reptiles.
(e) Riverfront Area. The topography, soil structure, plant community composition and
structure, and hydrologic regime can provide the following important wildlife habitat
functions:
1. Food, shelter, overwintering and breeding areas for wildlife, including turtle nesting
areas, nesting sites for birds which typically reuse specific nesting sites, cavity trees, and
isolated depressions that function as vernal pools.
2. Migratory areas along the riparian corridor including the movement of wildlife
unimpeded by barriers within the riverfront area.
(3) Restoration and Replication of Altered Habitat. Alterations of wildlife habitat
characteristics beyond permissible thresholds may be restored onsite or replicated offsite in
accordance with the following general conditions, and any additional conditions the issuing
authority deems necessary to insure that the standard in 310 CMR 10.60(1)(a) is satisfied:
(a) the surface of the replacement area to be created ("the replacement area") shall be equal
to that of the area that will be lost ("the lost area");
(b) the elevation of groundwater relative to the surface of the replacement area shall be
approximately equal to that of the lost area;
(c) the replacement area shall be located within the same general area as the lost area. In
the case of banks and land under water, the replacement area shall be located on the same
water body or waterway if the latter has not been rechanneled or otherwise relocated. In the
case of bordering land subject to flooding, the replacement area shall be located
approximately the same distance from the water body or waterway as the lost area. In the
case of vernal pool habitat, the replacement area shall be located in close proximity to the
lost area;
(d) interspersion and diversity of vegetation, water and other wildlife habitat characteristics
of the replacement area, as well as its location relative to neighboring wildlife habitats, shall
be similar to that of the lost areas, insofar as necessary to maintain the wildlife habitat
functions of the lost area;

310 CMR: DEPARTMENT OF ENVIRONMENTAL PROTECTION
10.60: continued
(e) the project shall not alter ten or more acres of Land Subject to Flooding or Land Under
Water found to be significant to the protection of wildlife habitat, or 2,000 feet or more of
Bank found to be significant to the protection of wildlife habitat (in the case of a bank of a
stream or river, this shall be measured on each side of said stream or river).
(f) if the replacement area is located in an area subject to M.G.L. c. 131, § 40, there shall
be no adverse effect on the existing important wildlife habitat functions of said area as
measured by the standards of 310 CMR 10.60;
(g) the "thresholds" established in 310 CMR 10.54(4)(a)5., 10.56(4)(a)4., 10.57(4)(a)3. and
10.58(4)(d)1.c. (below which alterations of resource areas are not deemed to impair capacity
to provide important wildlife habitat functions) shall not apply to any replacement area; and
(h) the replacement area shall be provided in a manner which is consistent with all other
General Performance Standards for each resource area in 310 CMR 10.51 through 10.60.
