BLM Completes Study on Proposed Electrical Transmission Line in Northern Maricopa County

PHOENIX – The Bureau of Land Management (BLM) today released its Final Environmental Impact Statement (EIS) for a 38-mile-long overhead electrical transmission line proposed to be built by the Arizona Public Service Company (APS).

The 500/230-kilovolt line would connect two APS substations in northern Maricopa County:  Sun Valley Substation, which is northwest of the White Tank Mountain Regional Park; and the Morgan Substation, which is south of Lake Pleasant Regional Park.

The proposed route includes about 7 miles of BLM-managed lands along State Route 74 and about 2 miles of BLM-managed lands near the Sun Valley Substation.  Private and Arizona State Trust lands make up the remainder of the proposed route.

The BLM is required by the National Environmental Policy Act of 1969, as amended, to assess the impacts when its lands would be affected.

The EIS evaluated APS’s proposed action, three additional alternatives, a sub-alternative proposed by the Arizona State Land Department, and a no action alternative.  The BLM’s Preferred Alternative, as identified in the EIS, is APS’s proposal.

The proposed transmission line project also would require an amendment to the BLM’s Bradshaw-Harquahala Resource Management Plan (RMP), which governs the area’s land use.  An amendment to the Bradshaw-Harquahala RMP, adopted in 2010, was considered in conjunction with the preparation of the EIS.

The proposed amendment would establish a multiple-use utility corridor along State Route 74. The affected area is designated in the plan now as a transportation corridor, but not as a utility corridor.  The amended plan would also change the area’s Visual Resource Management classification from Class III to Class IV.  Class IV is less restrictive and would allow changes to the landscape associated with the construction of transmission lines.

The BLM’s Preferred Alternative for the route coincides with an Arizona Corporation Commission approved route.

The BLM manages more than 245 million acres of public land, the most of any Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska. The BLM also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM's mission is to manage and conserve the public lands for the use and enjoyment of present and future generations under our mandate of multiple-use and sustained yield. In Fiscal Year 2014, the BLM generated $5.2 billion in receipts from public lands.
