The provisions of this section are intended to encourage the appropriate development of wind resources by residents of Elko County in appropriate locations within the county. It is designed to establish the public processes needed to identify preferred locations for wind turbines and other devices that convert wind energy to electricity, and create a clear regulatory path that will address specifically, wind turbine deployment.
This section pertains to residential wind turbines and towers with a maximum rated output of one hundred (100) kilowatts, commercial wind facilities, and wind monitoring or meteorological towers both commercial and noncommercial.
Although Elko County has been the site of wind machines in its past, typically those were used for water pumping for agriculture (livestock) uses. The types of machines now being contemplated and proposed differ from those historic devices in purpose, size, technology, cost and potential environmental impact. As renewable energy technology develops, particularly wind power, we see a rapidly changing field as more and more individuals give serious consideration to wind turbines as a means of supplying some or all of their electricity requirements.
It is therefore the intent of this section "Wind Machine Ordinance" to provide the county of Elko with an ordinance to understand the land use issues regarding wind power and to enable its residents to plan for the installation of modern wind electrical generating equipment. It is the express purpose of this section to provide for a permitting process to accommodate residential wind energy and commercial wind conversion facilities in appropriate locations, while minimizing any adverse visual, safety or environmental impacts of the facilities.
This section enables the review and approval of proposals for wind energy conversion facilities through the conditional use process within section
4-9-6 of this title. This section is intended to be used in conjunction with the Nevada Revised Statutes, Elko County master plans and other regulations adopted or enacted by Elko County, including, but not limited to, site plan review, and other factors.
A-WEIGHTED SOUND PRESSURE LEVEL (dBA): The sound pressure level in decibels as measured on a sound level meter using the A-weighted filter network. The A-weighted filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise.
AMBIENT NOISE: The composite of noise from all sources near and far; the normal or existing level of environmental noise at a given location.
ANEMOMETER: An instrument that measures the force and direction of the wind.
CLEAR FALL ZONE: An area surrounding the wind turbine unit into which the turbine and/or turbine components might fall due to inclement weather, poor maintenance, faulty construction methods, or any other condition causing turbine failure that shall remain unobstructed and confined within the property lines of the primary parcel where the turbine is located at, the purpose being that if the turbine should fall or otherwise become damaged, the falling structure will be confined to the primary parcel and will not fall onto dwellings, accessory buildings, and will not intrude onto a neighboring property.
COWLING: A streamlined removable metal that covers the turbines nacelle.
DISCONNECT, MANUAL: A device by which the conductors of a circuit can be disconnected from the source of supply.

L50: The noise level exceeded fifty percent (50%) of the time during a given period of time.
LeqA: The equivalent or energy averaged noise level.
Lmax: The highest root-mean-square (RMS) noise level measured over a given period of time.
METEOROLOGICAL TOWERS: Those towers which are erected primarily to measure wind speed and directions plus other data relevant to siting wind machines, and include the tower, guy cables and hardware, anemometers, wind direction vanes, booms to hold equipment, data logger, instrument wiring, and 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.

PRIMARY STRUCTURE: For each property, the structure that one or more persons occupy the majority of time on that property for either business or personal reasons. Primary structures include structures such as residences, commercial buildings, hospitals, and daycare facilities. Primary structures exclude structures such as storage sheds, pool houses, unattached garages, and barns.
PRIVATE WIND ENERGY CONVERSION MACHINE: A wind machine having a minimum rated capacity of two (2) kilowatts and a maximum rated capacity of one hundred (100) kilowatts and designed to offset energy costs of the existing principal uses on parcels of land for the purposes of these regulations.

ROTOR: That part of a wind energy system comprised of an assembly of rotating airfoils.
SHADOW FLICKER: Alternating changes in light intensity caused by the moving blade casting shadows on stationary objects, such as a residential dwelling which exceeds ten (10) hours a year.
