On Nov. 7, 2017, the PUC announced adoption of a rule establishing sound standards for wind-generation facilities. The PUC’s rule sets standards for three categories of wind facilities:
- small (up to 50 kW)
- medium (50 to 150 kW)
- large (greater than 150 kW)
Decibel Limits by Wind Facility Size
- Small and Medium - 42-decibel limit 100 feet from nearby residences
- Large - 42 decibels during the day and 39 decibels at night
