SouthCoast Expansion
Applicant Prepared Environmental Assessment

In order to meet the growing needs of 12 natural gas customers in the southeastern market, Transco proposed to provide 204,099 Dth/day of new capacity to their existing system, including 80,000 Dth/day to Santee Coopers planned Rainey GS. The facilities would consist of 44.3 miles of 24-, 42- and 48-inch-diameter pipeline and 31,500 horsepower of compression in Alabama and Georgia. In addition, Santee Cooper would construct and operate 2.1 miles of 16-inch-diameter pipeline to its planned power GS in Anderson County, S.C. In November 2000, FERC approved the SouthCoast Expansion Project.

Everett Delta Lateral
Applicant Prepared Environmental Assessment

Northwest Pipeline Corporation (Northwest) proposed to expand gas facilities in Snohomish County, WA. to supply natural gas to a 248-megawatt combined-cycle power generating plant being constructed in Everett, W.A. The proposed Everett Delta Lateral would have a design capacity of approximately 133,000 dekatherms per day (Dth/day), of which up to 90,000 Dth/day would be delivered to fuel the power plant and 43,000 Dth/day to other local distribution systems operated by Puget Sound Energy. Northwest would install approximately nine miles of 20-inch-diameter pipeline with a tie-in to the existing mainline and loop north of the city of Lake Stevens. In addition, Northwest proposes to construct two mainline taps, a 20-inch block valve assembly, a pig launcher and receiver, a liquids separator and two delivery points at a joint meter station site at the end of the pipeline.

Grays Harbor Lateral
Applicant Prepared Environmental Assessment

Northwest intends to expand its gas facilities in Thurston and Grays Harbor Counties, WA. The proposed lateral would have a design capacity of 161,500 Dth/day, all of which would be delivered to provide electricity generation at Duke Energy Grays Harbor's (DEGH) proposed 650-rnegawatt Satsop Combustion Turbine (CT) Project. A portion of the plants output is already committed to Energy Northwest, and the balance will be delivered to the Bonneville Power Administration (BPA) grid to help satisfy current and projected power demand. The Satsop CT Project and proposed pipeline have undergone extensive regulatory review, including a 1995 Environmental Impact Statement (EIS) prepared for BPA and a Washington State Energy Facility Site Evaluation Council review, leading to site certification in 1996. The proposed facilities would consist of 49 miles of 20-inch-diameter pipeline and associated above ground facilities, including a tie-in to Northwest's existing 25-inch-diameter mainline and 30-inch-diameter loop pipelines; block valve assemblies; modifications to Northwest's existing Turnwater Compressor Station; and a new meter station at the end of the pipeline to service DEGH.
