                                    ' Sound level surveys were conducted during the initial operation and testing of the GTGs. The three GTGs were operated for one hour during the initial' test period. No cemplaints related to noise or sound levels were received as a result of this testing. The maximum sound levels recorded at          i the GTGs were determined to be approximately 120 dBA. Subsequently, a fence was erected to surround the GTGs at a nominal distance of 50 feet where sound levels were determined to be approximately 85 dilA. The area inside the fence has.been posted as a mandatory hearing protection area.
