11 Binks Solar Project Narrative Sunlight Partners respectfully submits the following as supporting documentation for the affirmation that the Binks Solar meets the requirements for approval of a Special Use within the Rural Buffer zoning district and that the project complies with the following standards (1) The use will maintain or promote the public health, safety and general welfare, if located where proposed and developed and operated according to the plan as submitted, The Binks Solar Project will maintain the public health, safety and general welfare if located where proposed and developed and operated according to the plan submitted The following addresses how the project will not adversely affect health, safety, and general welfare Public Safety- The Binks Solar facility will not adversely affect public safety The solar facility is an unmanned, infrequently visited project site. As such, the project will not increase the existing demand on public safety agencies (police and fire departments) The project site will be enclosed with a fence, preventing access to the general public. Attachment is a ground mounted solar question and answer guide developed jointly by the Massachusetts Department of Energy Resources, Massachusetts Department of Environmental Protection and the Massachusetts Clean Energy Center The attached guide addresses public safety concerns such as Hazardous Materials, Electric and Magnetic Fields (EMF), and Noise Noise- According to the Orange County noise ordinance "A Resolution and Ordinance to Provide for the Control of Noise in Orange County" amended February f, 1988, Sound Levels dB(a) by Receiving Land generally cannot exceed 60 dB(a) during the daytime and 50 dB(a) during the nighttime The Binks Solar Project proposes to use Advanced Energy Soloron 500 inverters. An acoustic analysis was performed on the inverter model (Attachment B) According to the study the inverter will produce 68 dB(o) of sound measured at three (3) meters from the inverter In an open area, sound levels decrease in accordance with the Inverse square law Generally, sound decreases 6 d8 for every doubling in distance from the sound source The sound generated by the Binks Solar project will be less than 38 dB(a) at any point along the property boundary (Far below the noise ordinance threshold) The following table summarizes the sound level generated by the project- Distance (Feet) Distance (Meters) Sound level (a- weighted) 3.28 1 68 dB(a) 6.56 2 62 dB(a) 1312 4 56 dB(a) 2625 8 50 dB(a) 5249 16 44 dB(a) 10499 32 38 dB(a) 209.97 64 32 dB(a) 41995 128 26 dB(a) 83990 256 20 dB(a)
