The purpose of this article is to establish guidelines for siting
wind energy turbines (WETs). The goals are as follows:
A.Â
To promote the safe, effective, and efficient use of a WET in order
to reduce the consumption of fossil fuels in producing electricity.
B.Â
To preserve and protect public health, safety, welfare, and quality
of life by minimizing the potential adverse impacts of a WET.
C.Â
To establish standards and procedures by which the siting, design,
engineering, installation, operation, and maintenance of a WET shall
be governed.
The following words, terms, and phrases, when used in this article,
shall have the meanings described to them in this section, except
where the context clearly indicates a different meaning:
The amount of background noise at a given location prior
to the installation of a wind energy turbine (WET) which may include,
but not be limited to, traffic, machinery, lawn mowers, human activity,
and the interaction of wind with the landscape. The ambient sound
level is measured on the dB(A) weighted scale as defined by the American
National Standards Institute.
A temporary wind speed indicator constructed for the purpose
of analyzing the potential for utilizing a wind energy turbine (WET)
at a given site. This includes the tower, base plate, anchors, cables
and hardware, wind direction vanes, booms to hold equipment, data
logger, instrument wiring, and any telemetry devices that are used
to monitor or transmit wind speed and wind flow characteristics over
a period of time for either instantaneous wind information or to characterize
the wind resource at a given location.
A unit of measure used to express the magnitude of sound
pressure and sound intensity. Decibels shall be measured on the dB(A)
weighted scale as defined by the American National Standards Institute.
The process of terminating operation and completely removing
a wind energy turbine (WET) and all related buildings, structures,
foundations, access roads, and equipment.
The encasement which houses all of the generating components,
gear box, drive tram, and other equipment in a wind energy turbine
(WET).
A special metering and billing agreement between utility
companies and their customers, which facilitates the connection of
renewable energy generating systems to the power grid.
A residence, school, hospital, church, public library, business,
or any other building used for public gatherings.
The entity responsible for the day-to-day operation and maintenance
of a wind energy turbine (WET).
The individual or entity, including their respective successors
and assigns, with equity interest in or ownership of a wind energy
turbine (WET).
The cross-sectional dimension of the circle swept by the
rotating blades of a wind energy turbine (WET).
The moving shadow, created by the sun shining through the
rotating blades of a wind energy turbine (WET). The amount of shadow
flicker created by a WET is calculated by a computer model that takes
into consideration turbine location, elevation, tree cover, location
of all structures, wind activity, and sunlight.

the wind hits the turbine blades before it hits the tower in order
to avoid the thumping noise which can occur if the wind is disrupted
by hitting the tower before the blades.
Any structure-mounted, small wind energy conversion system
that converts wind energy into electricity through the use of a wind
generator, and includes the nacelle, rotor, tower, and pad transformer,
if any.

Any SSMWET or STMWET that is to be decommissioned shall be done
so in accordance with the following requirements:
A.Â
The WET owner(s) or WET operator(s) shall complete decommissioning
within six months after the end of the useful life. Upon request of
the WET owner(s) or WET operator(s) of the SSMWET or STMWET, and for
a good cause, the Zoning Administrator may grant a reasonable extension
of time. The SSMWET or STMWET will be presumed to be at the end of
its useful life if no electricity is generated for a continuous period
of six months; the end of its useful life may also be established
by other facts and circumstances determined by the Zoning Administrator.
All decommissioning expenses are the responsibility of the WET owner(s)
or WET operator(s).
B.Â
If the WET owner(s) or WET operator(s) fails to complete decommissioning
within the period prescribed above, the Village Council may designate
a contractor to complete decommissioning with the expense thereof
to be charged to the violator and/or to become a lien against the
property and added to the next tax statement issued for the property
upon which the SSMWET or STMWET is located. If the SSMWET or STMWET
is not owned by the lot owner(s), a bond, security deposit or bank
letter of credit must be provided to the Village for the cost of decommissioning
each SSMWET or STMWET prior to construction.
C.Â
In addition to the decommissioning requirements listed previously,
the STMWET shall also be subject to the following:
(1)Â
Decommissioning shall include the removal of each STMWET, buildings,
electrical components, and any other associated facilities. Any foundation
shall be removed to a minimum depth of 60 inches below grade, or to
the level of the bedrock if less than 60 inches below grade.
(2)Â
The site and any disturbed earth shall be stabilized, graded,
and cleared of any debris by the WET owner(s) or its assigns. The
site shall be seeded to prevent soil erosion.
(3)Â
All WET applications shall provide a decommissioning plan and
performance bonds as necessary by the Village.
(4)Â
Legal agreements may be required between the WET owner/operator
and the Village to ensure compliance with all decommissioning requirements.
Should an aggrieved property owner allege that the SSMWET or
STMWET is not in compliance with the noise or shadow flicker requirements
of this chapter, the procedure shall be as follows:
A.Â
Noise complaint.
(1)Â
Notify the Village, in writing, regarding concerns about noise
level. If the complaint is deemed sufficient by the Village to warrant
an investigation, the Village will request the aggrieved property
owner deposit funds in an amount sufficient to pay for a noise level
test conducted by a certified acoustic technician to determine compliance
with the requirements of this chapter.
(2)Â
If the test indicates that the noise level is within chapter
noise requirements, the Village will use the deposit to pay for the
test.
(3)Â
If the SSMWET or STMWET owner(s) is in violation of the noise
requirements, the owner(s) shall reimburse the Village for the noise
level test and take immediate action to bring the SSMWET or STMWET
into compliance which may include ceasing operation of the WET until
chapter violations are corrected. The Village will refund the deposit
to the aggrieved property owner.
(4)Â
If the WET owner(s) fails to correct the violation(s), the Village
Council may designate a contractor to make the corrections with the
expense thereof to be charged to the violator. If the WET owner(s)
fails to reimburse the Village for the noise level test the cost will
become a lien against the property and added to the next tax statement
issued for the property upon which the WET is located.
B.Â
Shadow flicker complaint.
(1)Â
Notify the Village, in writing, regarding concerns about the
amount of shadow flicker. If the compliant is deemed sufficient by
the Village to warrant an investigation, the Village will request
the aggrieved property owner deposit funds in an amount sufficient
to pay for a shadow flicker analysis of the turbine as constructed
to determine compliance of the requirements of this chapter.
(2)Â
If the test indicates that the flicker shadow is within chapter
noise requirements, the Village will use the deposit to pay for the
test.
(3)Â
If the SSMWET or STMWET owner(s) is in violation of the chapter
shadow flicker requirements, the owner shall take immediate action
to bring the SSMWET or STMWET into compliance which may include ceasing
operation of the WET until the chapter violations are corrected. The
Village will refund the deposit to the aggrieved property owner.
(4)Â
If the WET owner(s) fails to correct the violation(s), the Village
Council may designate a contractor to make the corrections with the
expense thereof to be charged to the violator. If the WET owner(s)
fails to reimburse the Village for the noise level test the cost will
become a lien against the property and added to the next tax statement
issued for the property upon which the WET is located.
