Plumbing Code Variance Request- New Lexington High School- 251 Waltham St
Mark Barrett, Facilities Project Manager, presented the new Lexington High School project, which is
asking the Board to support a variance to the Massachusetts Plumbing Code 248 CMR 10.13
regarding the treatment of special waste in science laboratories. Also participating in the discussion
were Reggie Hobbs, Science Department Head, Brian Wan, Plumbing Engineer with SMMA, Mike
Cronin, Director of Public Facilities, and James Kennedy, Lexington Plumbing Inspector.
Mr. Barrett explained that the project team is seeking approval to reduce the number of acid-
neutralization systems (chip tanks) installed in the new proposed high school building. Under a
traditional interpretation of the plumbing code, chip tanks could be required at all science laboratory
sinks. In the proposed design, chip tanks would only be at sinks within science prep rooms and
certain specialty spaces, such as the photography lab.
Mr. Hobbs described the science department’s chemical management and disposal practices. He
explained that laboratory activities are conducted using micro-scale quantities of chemicals,
significantly reducing the volume of hazardous waste generated. Chemical waste is collected by
teachers, neutralized when appropriate, and either disposed of safely or stored for removal by the
district’s hazardous waste contractor, Clean Harbors. He noted that chemical disposal is managed by
staff rather than students and that the department maintains established procedures for handling
laboratory waste.
Mr. Wan stated that the project team believes the proposed approach satisfies the intent of the
plumbing code because special waste would not be discharged directly into classroom sinks. He
explained that current educational practices and departmental policies make the installation of chip
tanks at every sink unnecessary and potentially redundant. He further noted that chip tanks require
ongoing maintenance and are often not used for their intended purpose.
Dr. Heiger-Bernays asked what the rationale is for the variance, future flexibility of the science
program, maintenance considerations, and the possibility of accidents or changes in curriculum over
time. Ms. Wolf-Fordham asked whether similar approaches had been used in other schools and
whether the reduced number of chip tanks could create future operational challenges.
Mr. Cronin acknowledged that the proposal would result in construction cost savings but emphasized
that the primary justification was educational practice and system effectiveness. He explained that
Lexington’s science program uses substantially smaller quantities of chemicals than traditional
laboratory models and that maintaining numerous chip tanks would create unnecessary maintenance
burdens. He noted that food, beverages, and other materials frequently disposed of in sinks can
damage chip tank systems and reduce their effectiveness. Mr. Cronin also stated that additional chip
tanks could be installed in the future if educational needs changed.
Ms. Escott asked whether limiting chip tanks to prep rooms reflected a shift toward teacher
demonstrations rather than student experimentation. Mr. Hobbs clarified that students continue to
conduct experiments, but many activities are now performed on a micro-scale using very small
quantities of chemicals. He emphasized that the prep room model provides flexibility while
supporting current safety and waste-management practices.
At the Board’s request, Mr. Barrett displayed floor plans showing the arrangement of science
classrooms and prep rooms. The plans demonstrated that each pair of science classrooms shares a
prep room equipped with a sink connected to a chip tank. Classroom sinks would remain available for
handwashing and general use but would not be connected to acid-neutralization systems. The project
team indicated that the proposal would reduce the number of chip tanks from approximately 175 to
approximately 12 throughout the building.
Mr. Kennedy stated that chip tanks are highly maintenance-intensive and noted that most high school
laboratory systems are designed with either chip tanks or centralized neutralization systems. He
explained that the proposed approach appears reasonable given the school’s waste-management
procedures and the availability of neutralization capability within the prep rooms. Mr. Kennedy
advised that the State Plumbing Board would ultimately determine whether the variance should be
granted and cautioned the applicants against relying primarily on cost savings as justification during
the variance process. He indicated that he was satisfied with the proposal as presented.
Board members also discussed training procedures. Mr. Hobbs clarified that science teachers receive
hazardous materials and safety training twice annually and that students receive laboratory safety
instruction before participating in experiments. He added that student laboratory assistants also
receive specialized training. In response to questions regarding accidental disposal of chemicals, he
reported that such incidents are rare and that existing procedures involve dilution and neutralization
when necessary.
Dr. Heiger-Bernays made a motion that the Board support the variance request to 248 CMR 10.13,
Piping and Treatment of Special Wastes, allowing acid-neutralization systems to be located in science
prep rooms rather than in the adjacent classrooms. The motion was seconded by Dr. Tung. The Board
of Health voted in favor of the motion 4-0-1 (Roll Call: Heiger-Bernays- yes; Dr. Tung-yes; Ms.
Escott-yes; Ms. Wolf-Fordham-abstain; Dr. Geller-yes). Motion Passed.
Minutes Approval:
The Board of Health reviewed the minutes of the April 20th, 2026, meeting.
Ms. Escott made a motion to accept the minutes as written.
Dr. Tung seconded the motion.
The motion was approved unanimously.
Health Staff Reports:
Ms. McCartin provided an update to the Public Health Nurse’s report. There was a positive case of Alpha-
gal syndrome through the Massachusetts disease surveillance system (MAVEN). Effective April 1, Alpha-
gal syndrome became a reportable condition in MAVEN. Follow-up revealed that the individual had been
diagnosed years earlier while residing in another state and is currently undergoing ongoing medical
monitoring and treatment. The recent positive test result was part of routine follow-up care and does not
represent a new case. The case appeared in MAVEN because of the new reporting requirement.
Dr. Heiger-Bernays asked about camp preparation and if camps are getting their applications and
documents submitted to the Health Department. Ms. McCartin stated that yes, they are, and there are the
same number of camps as last year. Dr. Heiger-Bernays emphasized the Board’s support in grant-funded
vaccination programs and appreciated Ms. Coleman’s efforts and the Health Department staff for applying
for and being awarded grants to support the vaccination program.
Mr. Sandeen noted that Lexington's COVID-19 infection rate is about one-third that of surrounding
communities and expressed appreciation for the Health Department's efforts in vaccinations and related
programs.
Ms. Yachachin updated the Board on the inspections, trainings, and meetings she has attended and has been
corresponding with camps to schedule meetings.
Director’s Report
Ms. McCartin provided a detailed update on planning efforts for several upcoming community events.
Preparations are ongoing for the annual BBQ Festival scheduled for the end of May, and coordinated with
event organizers and participating vendors. Health Department staff are also working with organizers of
the Farmers’ Market in advance of its seasonal opening. The Farmers’ Market will return on the Tuesday
following Memorial Day and will be returning to Fletcher Park.
Ms. McCartin stated that the Health Department has been preparing for a proposed FIFA World Cup
watch party, which is anticipated to take place in June. Planning for the event is currently in the
preliminary stages, as final approval from FIFA has not yet been received, and the necessary event
licenses have not yet been issued. Organizers are exploring having food trucks attend the events and have
submitted an application for an alcohol license as part of the event planning process. Ms. McCartin noted
that further planning and coordination will continue pending receipt of the required approvals and permits.
Board of Health Member- Committee Liaison Reports
