- WIND ENERGY STRUCTURES AND FACILITIES
The purpose of this article is to establish guidelines for siting wind energy turbines (WETs). The goals are as follows:
1.
To promote the safe, effective and efficient use of a WET in order to reduce the consumption of fossil fuels in producing electricity.
2.
Preserve and protect public health, safety, welfare, and quality of life by minimizing the potential adverse impacts of a WET.
3.
To establish standards and procedures by which the siting, design, engineering, installation, operation, and maintenance of a WET shall be governed.
(Ord. No. 156-16, § I, 10-20-14)
Ambient sound level is the amount of background noise at a given location prior to the installation of a WET(s) which may include, but not be limited to, traffic, machinery, lawnmowers, human activity, and the interaction of the 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 is a temporary wind speed indicator for the purposed 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, and wind flow characteristics over a period of time for instantaneous wind information or to characterize the wind resource at a given location.
Decibel is defined as 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 is the process of terminating operation and completely removing a WET(s) and all related building, structures, foundations, access roads, and equipment.
Large wind energy turbine (L-WET) is 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 L-WET has a nameplate above 250 kilowatts and the main purpose of the L-WET is to supply electricity to off-site customers. The total height exceeds 150 feet.
Medium wind energy turbine (M-WET) is 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 M-WET has a nameplate capacity that does not exceed 250 kilowatts. The total height does not exceed 150 feet.
Nacelle refers to the encasement which houses all of the generating components, gear box, drive tram, and other equipment.
Net-metering is 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.
Occupied building is a residence, school, hospital, church, public library, business, or any other building used for public gatherings.
Operator is the entity responsible for the day-to-day operation and maintenance of a wind energy turbine (WET).
Owner is the individual or entity including their respective successors and assigns that have an equity interest or own the wind energy turbine (WET) in accordance with this article.
Rotor diameter is the cross-sectional dimension of the circle swept by the rotating blades of a WET.
Shadow flicker is 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 tower-mounted wind energy turbine (STM-WET) is 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 STM-WET has a nameplate capacity that does not exceed 30 kilowatts. The total height does not exceed 120 feet.
Structure is any building or other structure, such as a municipal water tower that is a minimum of 12 feet in height at its highest point of roof and is secured to frost-footings or a concrete slab.
Small structure mounted wind energy turbine (SSM-WET) 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 SSM-WET is attached to a structures roof, walls, or other elevated surface. The SSM-WET has a nameplate capacity the does not exceed ten kilowatts. The total height does not exceed 15 feet as measured from the highest point of the roof, excluding chimneys, antennae, and other similar protuberances.
Total height is the vertical distance measured from the ground level at the base of a tower to the uppermost vertical extension of any blade, or the maximum height reached by any part of the wind energy turbine (WET).
Tower is a freestanding monopole that supports a wind energy turbine (WET).
Upwind turbine is a wind energy turbine (WET) positioned in a manner so that 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.
Wind energy turbine (WET) is any structure-mounted, small, medium, or large 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.

All access roads to the M-WET or L-WET shall be removed, cleared, and graded by the M-WET or L-WET Owner(s), unless the property owner(s) requests, in writing, a desire to maintain the access road. The City of Richmond will not be assumed to take ownership of any access road unless through official action of the Richmond City Council.
d.
The site and any disturbed earth shall be stabilized, graded, and cleared of any debris by the owner(s) of the M-WET or L-WET or its assigns. If the site is not to be used for agricultural practices following removal, the site shall be seeded to prevent soil erosion, unless the property owner(s) request in writing that the land surface areas not be restored.
e.
In addition to the decommissioning requirements listed previously, the M-WET shall also be subject to the following:
i.
If the M-WET owner(s) or operator(s) fails to complete decommissioning within the period prescribed above, the city 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 premises. If the M-WET is not owned by the property owner(s), a bond must be provided to the City for the cost of decommissioning each M-WET.
f.
In addition to the decommissioning requirements previously listed, the L-WET shall also be subject to the following:
i.
An independent and certified professional engineer shall be retained to estimate the total cost of decommissioning ("Decommissioning Costs") with no regard to salvage value of the equipment, and the cost of decommissioning net salvage value of the equipment ("Net Decommissioning Costs"). When determining the amount, the city 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 city planner after first year of operation and every fifth year thereafter.
ii.
The L-WET 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 city.
iii.
Decommissioning funds shall be in the form of a performance bond made out to the city.
iv.
A condition of the bond shall be notification by the bond company to the city planner when the bond is about to expire or be terminated.
v.
Failure to keep the bond in effect while a L-WET is in place will be a violation of the special land use permit. If a lapse in the bond occurs the city may take action up to and including requiring ceasing operation of the WET until the bond is reposted.
vi.
The escrow agent shall release the decommissioning funds when the owner(s) has demonstrated and the city concurs the decommissioning has been satisfactorily completed, or upon written approval of the city 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 A and B), then the city may take such measures as necessary to complete decommissioning. The entry into and submission of evidence of a participating landowner agreement to the city shall constitute agreement and consent of the parties to the agreement, their respective heirs, successors and assigns that the city may take such action as necessary to implement the decommissioning plan.
13.
Public inquiries and complaints:
a.
Should an aggrieved property owner allege that the SSM-WET or STM-WET is not in compliance with the noise requirements of this article, the procedure shall be as follows:
i.
Notify the City of Richmond in writing regarding concerns about noise level.
ii.
If the complaint is deemed sufficient by the city to warrant an investigation, the city 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 article.
iii.
If the test indicates that the noise level is within ordinance noise requirements, the city will use the deposit to pay for the test.
iv.
If the SSM-WET or STM-WET owner(s) is in violation of the ordinance noise requirements, the owner(s) shall reimburse the city for the noise level test and take immediate action to bring the SSM-WET or STM-WET into compliance which may include ceasing operation of the WET until ordinance violations are corrected. The city will refund the deposit to the aggrieved property owner.
