Northern Development LLC Wind Turbine Project

SERVICE:

Noise Study

DESCRIPTION:

Northern Development LLC is building a 900-kW PowerWind PW56 wind turbine on land in an industrial district in Ontario, NY as part of the Wayne Industrial Sustainability Park (WISP) Project. In order to obtain a permit for this turbine, Northern Development needed to demonstrate that the noise generated by the turbine would not violate the Town noise ordinance. Tech Environmental, Inc. (Tech) was hired by Northern Development to conduct a sound study.

Tech performed a study of the wind turbine sounds at the project's property lines and the nearest residential structure using the Cadna-A acoustic model. As a result of this study, Tech concluded that the wind turbine project fully complies with the Town of Ontario Noise Ordinance limit of 75 dBA on the industrial property lines. The study further concluded that the maximum sound level increase caused by the turbine at the nearest residence would very comfortably comply with the 6-dBA incremental limit recommended in the NYS DEC Noise Guideline.
