The OPSB application must report construction and operating noise at each residence by day and night, with a preconstruction background noise study.
Design goal is measured daytime background Leq plus 5 dBA at non-participating residences, proposed by Northfold as a certificate condition.
Daytime background Leq was 36 to 41 dBA and nighttime L90 was 28 to 31 dBA, measured May 16 to 23, 2023.
Predicted operating sound exceeds the design goal at two non-participating residences: R-6 by 3 dBA and R-7 by 2 dBA.
Predicted nighttime level at R-6 is 43 dBA, about 14 dBA above nighttime background, driven by battery cooling equipment.
The main power transformer may produce an audible 120 Hz tone at R-7.
Mitigation options for R-6 and R-7 are under evaluation and none had been selected when the report was issued.
