[Added 12-29-2005 by L.L. No. 5-2005]
In order to ensure that the placement, construction, and modification of windmills and wind generators conforms to the Town's purpose and intent of this article, the Town Board is hereby authorized to grant wind energy conversion system (WECS) conditional use permits pursuant to this article. The Town Board hereby adopts an overall policy with respect to WECS conditional use permits for windmills and wind generators for the express purpose of achieving the following goals:
A. 
Implementing an application process for person(s) seeking a WECS conditional use permits for windmills and wind generators.
B. 
Establishing a policy for examining an application for, and issuing a WECS conditional use permit for, windmills and wind generators that is both fair and consistent.
C. 
Establishing reasonable time frames for granting or not granting WECS conditional use permits for windmills and wind generators, or recertifying or not recertifying or revoking the WECS conditional use permit granted under this article.
D. 
Promoting and encouraging, wherever possible, the placement of WECS in such a manner as to cause minimal disruption to aesthetic considerations of the land, lot, property, buildings, and other facilities adjacent to, surrounding, and in generally the same area as the requested location of such WECS.
E. 
Minimize adverse visual effects from WECS facilities by requiring careful siting, visual impact assessment and appropriate screening.

Upon removal of said facilities, the land shall be restored to its previous condition, including but not limited to the seeding of exposed soil.
(2) 
The applicant must submit an analysis by a New York State-licensed professional engineer of the cost of removal of the WECS and surrounding property restorations.
(3) 
Prior to obtaining a building permit, the applicant must provide a financial security bond for the removal of the WECS, with Avon as the designated assignee, in an amount approved by the Planning Board which is equal to 110% of the estimated removal cost. The bond shall provide for an annual adjustment for the cost of inflation.
(4) 
The provisions of this section may be waived by the Planning Board for good cause shown in the case of a residential WECS.
F. 
Noise control.
(1) 
Prior to the issuance of a building permit, the WECS manufacturer shall provide sufficient data and documentation to establish that the WECS will not produce noise levels in excess of those stipulated in the following table:
Maximum Permitted
Without Windmill
(decibels)
Windmill Operating
(decibels)
45
55.4
50
56.2
55
61.0
60
61.2
65
65.4
(2) 
Decibel level readings shall be measured at the closest property line to the WECS. Ambient noise levels shall be measured prior to construction. All measurements shall be made by a licensed engineer approved by the Planning Board. The applicant shall provide and pay for the engineer.
(3) 
After the WECS has been approved and installed, sound measurement shall be performed to determine ambient and operating decibel levels. The sound level shall be measured on a sound level meter using the A-weighting network.
(4) 
Upon the complaint of an abutter, ambient and maximum permitted decibel measurements shall be performed by an agent designated by the Planning Board. The agent shall submit recorded sound measurements to the Planning Board for review and evaluation. A fee for the service shall be established by the Planning Board. The fee shall be paid for by the complainant unless maximum permitted decibel readings have been exceeded, in which case the WECS owner shall pay the fee.
(5) 
If maximum readings are exceeded, the installation shall be considered a public nuisance. The violation shall be corrected within 90 days from the date of notification, and if the noise violation cannot be remedied, the WECS shall be removed or relocated.
G. 
Electromagnetic interference.
(1) 
Prior to the issuance of a building permit, the manufacturer shall provide sufficient data and documentation to establish that the installation will not cause electromagnetic interference to any abutter.
(2) 
The WECS installation shall comply with Federal Communications Commission Regulation 47 CFR 15.
(3) 
Upon the complaint of an abutter, an investigation shall be performed by an agent of the Planning Board. The agent shall submit a report of his findings to the Planning Board for review and evaluation. A fee for the report shall be established by the Planning Board. After review and evaluation of the report, the Planning Board shall determine if the installation causes electromagnetic interference to any abutter. The fee for the report shall be paid by the complainant, unless the Planning Board determines that there is electromagnetic interference to an abutter, in which case the owner shall pay the fee.
(4) 
If electromagnetic interference is caused by the installation of a WECS, the installation shall be deemed a public nuisance subject to abatement by the Town. The violation shall be corrected within 90 days from the date of notification. If the electromagnetic interference cannot be remedied, the WECS shall be removed or relocated.
H. 
Guy wires. For all guyed towers, visible and reflective objects, such as plastic sleeves, reflectors or tape, shall be placed on the guy wire anchor points and along the outer- and innermost guy wires up to a height of eight feet above the ground. Visible guards shall be installed on or around anchor points of guy wires.
I. 
Maintenance. Every two years in the case of a commercial WECS and every five years in the case of a residential WECS the owner shall submit a structural report from a New York State-licensed engineer to the Building Inspector attesting to the structural integrity of the wind generator, tower and/or support system.
J. 
Environmental. Solid and hazardous wastes, including but not limited to crates, packaging materials, damaged or worn parts, as well as used oils and lubricants, shall be removed from the site promptly and disposed of in accordance with all applicable local, state and federal regulations.
