POWER COUNTY ORDINANCE
AN ORDINANCE THAT SPLITS PRIOR POWER COUNTY ORDINANCE 10-19 INTO TWO SECTIONS. PREVIOUSLY, GAS AND POWER LINES WERE HANDLED IN THE SAME SECTION. THIS ORDINANCE AMENDS 10-19 TO ONLY COVER ELECTRIC TRANSMISSION LINES.
BE IT ORDAINED BY THE BOARD OF COMMISSIONERS OF POWER COUNTY IDAHO:
The purpose of this chapter is to provide a set of standards for the development and installation of electric transmission structures and related facilities. The regulations contained herein are designed to protect and promote public health, safety and the community welfare of Power County, and to encourage the managed development of electric transmission structures, while not unduly restricting the development of needed electric transmission structures and related facilities.
The county shall apply these regulations to accomplish the following:
A. Minimize adverse visual effects as well as potential hazardous effects of electric transmission structures and related facilities through design and siting standards.
B. Provide a process for obtaining necessary permits for electric transmission structures and related facilities while at the same time protecting the health, safety and welfare of the citizens of Power County.
C. Protect environmentally sensitive areas of Power County by regulating the location, design and operation of electric transmission structures and related facilities.
D. Protect the economic base of Power County by eliminating or minimizing the adverse impact upon agriculture and residences by regulating the location, site and operation of utility transmission systems.
Furthermore, this chapter is not intended to regulate residential power lines.
For the purpose of this chapter, the following terms and phrases shall have the meanings ascribed to them in this section:
BUILDING: Any structure having a roof supported by columns or walls and intended for the shelter, housing, or enclosure of any individual, animal, process, equipment, goods, or materials of any kind.
CAMOUFLAGED TOWER: Any electric transmission tower that due to design or appearance entirely hides, obscures, or conceals the presence of the tower and antennas.
FACILITIES: The components or structures built for the utility transmission system, which would include the electrical transmission towers and wires, the construction to substations, and any other components of the utility transmission system which would be erected, constructed or placed within Power County.
GUYED TOWER: An electric transmission tower that is supported in whole or in part by guywires and ground anchors or other means of support besides the superstruct ure of the tower itself.
HEIGHT, UTILITY TRANSMISSION TOWER: The distance measured from the original grade at the base of the tower to the highest point of the tower. This measurement excludes any attached antennas, protection devices (e.g., lightning rods) and lighting.
LATTICE TOWER: An electric transmission tower that consists of vertical and horizontal supports and crossed metal braces.
MONOPOLE: An electric transmission tower of a single pole design.
NAVIGABLE STREAM OR LAKE: As designated on the United States geological survey (USGS) map and/or the Power County zoning maps.
NONCONFORMING: Any preexisting utility transmission facility that was in existence prior to the adoption hereof and that has not been issued to a special use permit or was issued a special use permit prior to the adoption date hereof.
OPERATION: Other than nominal use; when a facility is used regularly as an integral part of an active system of natural gas and electric transmission structure.
RESIDENCE: A building occupied or used for living quarters by persons at least four (4) months out of the year.
SUBSTATION: An electrical substation as a subsidiary station of an electricity transmission system, containing transformers, switches, control equipment, circuit breakers and other elements, including line termination structures. Substations are to be fenced enclosures or buildings.
UTILITY TRANSMISSION SYSTEM: The electrical transmission towers and wires and/or the natural gas or other gas pipelines used for the transmission of electrical power of two hundred thirty thousand (230,000) volts or more, and associated substations and switchyards, or gas through corridors across the county to connect with systems in other counties, not for origination, destination or termination within Power County.
10-19-4: EXEMPT FROM COUNTY REVIEW:
The following shall be permitted without county approvals:
A. Electrical transmission lines used solely for residences, or business purposes, with capacities of four hundred sixty (460) volts or less.
10-19-5: AREAS LIMITING ELECTRIC TRANSMISSION STRUCTURES LOCATION:
A. Electric transmission structures may be permitted in the following areas, subject to special use permits and approval by the Power County planning and zoning commission but are subject to review and approval of the federal aviation administration (FAA) and other appropriate agencies, if applicable:
1. One-half (1/2) mile radius from heliports.
2 One-half (1/2) mile radius from private airport runway(s).
10-19-6: ZONES LIMITING UTILITY TRANSMISSION SYSTEMS:
A. As much as is reasonably possible, no utility transmission systems should be allowed in land zoned rural residential, commercial, light industrial, or agricultural. Utility transmission systems should be located in land zoned heavy industrial wherever possible.
B. Unless unreasonable, or absolutely necessary, no systems may be located on irrigated farmland. The planning and zoning commission should carefully consider alternatives to locating utility transmission structures on any type of working agricultural land, including CRP land, due to the potential adverse impact. Alternatives on public land or land not actively managed or used for agriculture should be preferred. The location of the utility transmission systems must be in compliance with the Power County comprehensive plan.
C. To the extent that any utility transmission lines go into substations as control points for any utility transmission system, the site, location or expansion of any substation within Power County must take into consideration the impact that expansion or construction, including bringing new transmission system lines into the substation will have on the related industries and resources of Power County. Whenever possible, expansion or construction of substations should not be allowed where they will have an adverse impact upon currently existing or future heavy industrial uses within Power County.
D. Any utility transmission systems sought to be located on working agricultural land including CRP land farm land or ranch land must be placed underground unless that would be impossible. An exception to this requirement must have the approval of the landowner adjacent land owners, landowners within 1,500 feet of the transmission system and the Power County Planning and Zoning Commission and the Board of County Commissioners.
10-19-7: AREAS PROHIBITING ELECTRIC TRANSMISSION STRUCTURES FACILITY LOCATION:
A. No electric facilities will be allowed within one thousand five hundred feet (1,500’) of the following areas:
1. Historic sites, as defined by state and/or federal regulation, unless otherwise controlled by federal or state law or regulation.
