[Definitions.]
Ambient sound level means the amount of ordinary background noise at a given location other than noise created by the WET, which may include, but not limited to, traffic, machinery, 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.
Anemometer means a temporary wind speed indicator constructed for the purpose of analyzing the potential for utilizing a wind energy turbine 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.
Condominium development means a development that is created under the Condominium Act (MCL 559.101 et seq.).
Decibel means 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.
Decommissioning means the process of terminating operation and completely removing a WET(s) and all related structures, foundations, access roads, equipment and restoration of any disturbed land associated with the WET.
General common element means an area designated for use by all owners within the condominium development.
Large wind energy turbine (LWET) means a tower-mounted wind energy system that converts wind energy into electricity through the use of equipment which includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, vane, wire, inverter, batteries, or other components used in the system. The LWET has a rated capacity above 250 kilowatts, and the main purpose of the LWET is to supply electricity to off-site customers.

Rotor diameter means the cross-sectional dimension of the circle swept by the rotating blades of a wind energy turbine (WET).
Shadow flicker means 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.
Small wind energy turbine (SWET) means a tower-mounted wind energy system that converts wind energy into electricity through the use of equipment which includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, vane, wire, inverter, batteries, or other components used in the system. The SWET has a rated capacity that shall not exceed 30 kilowatts. The total height shall not exceed 120 feet.
Structure means any building or other structure, such as a municipal water tower, that is a minimum of 12 feet high at its highest point of roof and is secured to frost-footings or a concrete slab.
Structure-mounted wind energy turbine (SMWET) converts wind energy into electricity through the use of equipment which includes any base, blade, foundation, generator, nacelle, rotor, tower, transformer, vane, wire, inverter, batteries, or other components used in the system. A SMWET is attached to a structure's roof, walls, or other elevated surface.
The SMWET has a rated capacity that shall not exceed ten kilowatts. The total height shall not exceed 15 feet as measured from the point where the WET attaches to the structure to the maximum height reached by any part of the WET.
Total height means the vertical distance measured from the ground level at the base of the tower to the maximum height reached by any part of the wind energy turbine (WET).

When determining this amount, the Township may also require an annual escalator or increase based on the federal consumer price index (or equivalent or its successor). Said estimates shall be submitted to the Township Zoning Administrator after the first year of operation and every fifth year thereafter.
ii.
The LWET owner(s) or operator(s) shall post and maintain decommissioning funds in an amount equal to net decommissioning costs; provided that at no point shall decommissioning funds be less than 100 percent of decommissioning costs. The decommissioning funds shall be posted and maintained with a bonding company or federal or state-chartered lending institution chosen by the owner(s) or operator(s) and participating landowner(s) posting the financial security. The bonding company or lending institution is authorized to conduct such business and is approved by the Township.
iii.
Decommissioning funds shall be in the form of a performance bond made out to PM Township.
iv.
A condition of the bond shall be notification by the bond company to the Township Zoning Administrator when the bond is about to expire or be terminated.

vi.
The escrow agent shall release the decommissioning funds when the owner(s) has demonstrated and the Township concurs that decommissioning has been satisfactorily completed, or upon written approval of the Township in order to implement the decommissioning plan.
vii.
If neither the owner(s) or operator(s), nor the landowner(s) complete decommissioning within the periods addressed previously (decommissioning requirements in subsections (d)(1) and (2) of this section), then PM Township may take such measures as necessary to complete decommissioning. The entry into and submission of evidence of a participating landowner agreement to the Township shall constitute agreement and consent of the parties to the agreement, their respective heirs, successors and assigns that the Township may take such action as necessary to implement the decommissioning plan.
