A.
The Zoning Board of Appeals, in accordance with its normal procedures, may grant variances for small WECS, but in no event shall the Zoning Board of Appeals grant a variance allowing a larger WECS than permitted by this chapter, or a WECS primarily designed to generate electricity for off-site use, or any large-scale multiple-tower wind facilities.
B.
If a court of competent jurisdiction orders the Zoning Board of Appeals to consider a use variance for any wind energy facility other than a small WECS or if the prohibition on any wind energy facility other than a small WECS is invalidated, no wind energy facility shall be allowed except upon issuance of a special use permit issued by the Town Board after a public hearing, which permit shall require a decommissioning plan and removal bond, site plan approval by the Planning Board pursuant to Article X of chapter 103, Zoning and a public improvement bond to protect public roads, and shall comply with the following minimum setbacks (the Zoning Board, upon a request for a use variance, may consider these standards in establishing conditions, but nothing in this section shall be read as deviating from the standards for granting use variances under state law nor limiting the Zoning Board's powers under SEQRA):
(1)
The statistical sound-pressure level generated by a WECS shall not exceed L10 - 45 dBA, measured at the nearest off-site dwelling existing at the time of approval (including structures under construction at said time), nor more than 6 dBA greater than either the nighttime or daytime preapplication background ambient noise level measured in leaf-off conditions for a period of no less than 24 hours. If the ambient sound-pressure level exceeds 45 dBA, the standard shall be ambient dBA plus 5 dBA. Independent certification shall be provided before and after construction demonstrating compliance with this requirement.
(2)
One thousand five hundred feet from the nearest site boundary property line.
(3)
One thousand five hundred feet from the nearest public road.
(4)
Two thousand five hundred feet from the nearest off-site residence existing at the time of approval, measured from the exterior of such residence.
(5)
One and one-half times the total height of the WECS from any non-WECS structure or any aboveground utilities.
(6)
Two hundred fifty feet from federal or state-identified wetlands, to protect bird and bat populations. This distance may be adjusted to be greater or lesser at the discretion of the reviewing body, based on topography, land cover, land uses and other factors that influence the flight patterns of resident birds.
