Windham adjusts nighttime Lmax in draft performance standards to end at 7 AM

Commission members reviewed Sec. 209 on performance standards, which anchors local authority to Section 4414(5) of the Act for noise measured at property lines. The draft includes a continuous weighted average ceiling of 70 dBA and a one-hour maximum of 120 dBA; the draft also contained a line referencing a nighttime Lmax of 39 dBA from 9:00 PM to 6:00 AM. The board decided to change the Lmax end time from 6:00 AM to 7:00 AM and opted not to add a daytime noise ordinance at this time.
