Project Description

El Paso Natural Gas Company, L.L.C. (EPNG), is proposing to construct, operate, maintain, and decommission a new lateral natural gas pipeline and delivery meter station in Mohave County, Arizona. The project would be approximately 3 miles east of Arizona State Route 95, near Mohave Valley, Arizona, within Sections 19 and 20, Township 18 North, Range 21 West, Gila and Salt River Baseline and Meridian.  The proposed 10-inch high-pressure natural gas lateral pipeline and associated facilities would deliver up to 41.72 million cubic feet per day of natural gas from two existing EPNG pipelines (EPNG Line No. 2121 [L2121] and No. L2153 [L2153]) to a meter station near a natural gas-fired power plant planned by Arizona Electric Power Cooperative (AEPCo) on private land near Mohave Valley, Arizona. The AEPCo power plant will be constructed on private lands west of the project area. AEPCo has requested to buy natural gas from EPNG. EPNG will deliver natural gas to the AEPCo plant either via a lateral pipeline crossing Bureau of Land Management (BLM)–managed land (the Proposed Action Alternative) or via a lateral pipeline crossing Arizona State Land Department (ASLD) and private lands (the No Action Alternative). EPNG has applied to amend their existing BLM right-of-way (ROW) authorization AZAZ106148534 (legacy serial number AZA19297, original ROW issued November 30, 1984, and renewed for a 30-year term on December 10, 2014) to include the additional ROW needed for the new lateral pipeline. The applicant requested the application to be processed using the Alternative Arrangements for Compliance with the National Environmental Policy Act amid the National Energy Emergency.
