for the contemplated tree plantings and fence. In that respect, the Committee asked Martha Wood to draft a letter asking Arlex for the following: 1) Information about the operations and the location of Arlex's Sudbury facility 2) A copy of the instructions for truck drivers posted on the board 3) A tentative plan showing the proposed location (delineating property lines and ownership) for the proposed trees and fence and their general description 4) Projected noise reduction estimates from the proposed planted trees and the fence After an e-mail review of Martha's draft to Arlex, the letter will be sent to Arlex by Tony Galaitsis. After a review of Arlex’s plans for tree plantings and fence by the NAC (before and during the next meeting), the NAC will prepare a letter summarizing its opinion about the mitigation plans and will submit it to the selectmen. 7. Noise Measurements The Lexington Noise By-law, Section 3.9, defines noise that violates the state regulation 310 CMR 7.10 according to Massachusetts Department of Air Quality Control Policy, DAQC 90- 001. The Committee reviewed DAQC Policy documents defining noise standards and measurements. The documents <http://www.mass.gov/dep/bwp/daqc/daqcpubs.htm#regs> and <http://www.nonoise.org/lawlib/states/mass/mass.httm#Air%20Pollution%20Control> describe the standard, and the document <http://www.mass.gov/dep/energy/noispol.htm> describes in detail how noise should be measured to determine whether it violates the policy. The Committee suggested that when complaints about repeated excessive noise incidents are lodged with the Board of Health or the Police Department, measurements be taken according to the state instructions. The LPD has a sound level meter and a staff person trained in its use. 8. Next Meeting The next meeting of NAC was tentatively scheduled for September 14 at 7:30 p.m. Jim Fearnside was asked to explore whether the Board of Health staff person could participate to record meeting minutes. These are draft minutes prepared by Julian Bussgang, edited based on comments by Tony Galaitsis and Richard Pagett.Any further suggested changes should be submitted to Tony Galaitsis. The final version of the minutes will be issued after the minutes have been officially accepted by the Committee.
