Start Preamble March 2, 2007.

The staff of the Federal Energy Regulatory Commission (FERC or Commission) has prepared an environmental assessment (EA) on the natural gas pipeline facilities proposed by Questar Pipeline Company (Questar) in the above-referenced docket. This EA has been prepared in cooperation with the U.S. Department of Interior's, Bureau of Land Management, U.S. Geological Survey, and U.S. Fish and Wildlife Service (collectively, “cooperating agencies”).

The EA was prepared to satisfy the requirements of the National Environmental Policy Act. The staff and cooperating agencies conclude that approval of the proposed project, with Start Printed Page 10511appropriate mitigating measures, would not constitute a major federal action significantly affecting the quality of the human environment.

The EA assesses the potential environmental effects of the construction and operation of the proposed Southern System Expansion Project II including:

Main Line 104 Extension Pipeline—Consisting of about 53.9 miles of new 24-inch-diameter pipeline loop and ancillary facilities in Uintah, Duchesne and Carbon Counties, Utah. The new pipeline would loop Questar's existing Main Line 40 northeast of Price, Utah and include a pig launcher, four new mainline block valves, a 200-barrel slug catcher, cathodic protection systems, and associated crossover piping, taps, and valves.

Main Line 104 Loop Pipeline—Consisting of about 4.7 miles of new 24-inch-diameter pipeline loop and ancillary facilities. The ML 104 Loop pipeline would parallel Questar's existing ML 104 between its existing Fausett Junction and Oak Spring Compressor Station facilities.

Blind Canyon Compressor Station Upgrades—Consisting of upgrades to one of two existing compressor units. Additional proposed facility upgrades would include the installation of about 1,200 feet of new station suction and discharge piping, one pig launcher, one pig receiver, one block valve, one spillover valve, one ultrasonic gas meter, and one filter separator.

Oak Spring Compressor Station Upgrades—Consisting of restaging two of the three existing compressor units. Additional proposed facility upgrades would include installation of one pig receiver, one block valve, and one valve associated with the pig receiver.

Price Yard Facilities—Consisting of approximately 200 feet of inlet and outlet piping, a 200-barrel slug catcher, a filter separator, and associated valves that would be installed within the boundary of the existing facility site.

The purpose of the Southern System Expansion Project II is to deliver up to approximately 175,000 dekatherms per day of natural gas on a firm basis from various receipt points on Questar's southern transmission system to a delivery point at an existing interconnect facility with the Kern River Gas Transmission Company pipeline near Goshen, Utah.

The EA has been placed in the public files of the FERC. A limited number of copies of the EA are available for distribution and public inspection at: Federal Energy Regulatory Commission, Public Reference and Files Maintenance Branch, 888 First Street, NE., Room 2A, Washington, DC 20426, (202) 502-8371.
