Construction noise and vibration
Pile driving is the loudest construction activity, at 85 to 95 dBA at 100 feet. The nearest non-participating
residence is 260 feet from the array fence (R-2), where pile driving would reach about 80 to 87 dBA for several
days. Blasting is not expected; pre-drilling where piles meet refusal is quieter than driving.

notice to residences within 1,000 feet a week before pile driving nearby; a complaint line; vibration monitoring
within 200 feet of any residence or well.
Recommendations
• Select and model a mitigation for the BESS yard and substation that brings R-6 and R-7 to the design goal by
day and by night before the OPSB application is filed.
• Specify a main power transformer with reduced sound power, or an enclosure, to remove the prominent tone at
R-7.
• Repeat background measurements in winter, when leaf cover and insect noise are absent, if OPSB staff ask
for seasonal data.
