Diameter

FERC has approved ETC Tiger Pipeline Co.’s proposal to build a 175-mile, 42-inch diameter pipeline to provide producers with up to 2 Bcf/d of takeaway capacity from the Haynesville Shale in East Texas and Northwest Louisiana.

FERC last Monday issued a certificate for the 675-mile, 42-inch diameter Ruby Pipeline project that would move 1.5 Bcf/d of Rockies natural gas from the Opal Hub in southwest Wyoming to Malin Hub near the Oregon-California border.

Gulf South plans to begin repairs at the start of Thursday’s gas day on Index 817 (its 42-inch diameter East Texas Expansion) in DeSoto Parish, LA. In order to reduce pipeline pressures to allow the maintenance, Gulf South said it will reduce scheduled capacity to 1.165 Bcf/d in the Expansion Area 16 Receipt scheduling group, which it expects to continue through Friday.

Boardwalk Pipeline Partners LP said each of its 42-inch diameter pipeline projects — the East Texas Pipeline, Southeast Expansion and Gulf Crossing Pipeline — have received authorization from the Pipeline and Hazardous Materials Safety Administration (PHMSA) to operate at their full design capacity of 0.80 of the specified minimum yield strength (SMYS) effective immediately. Previously each of these projects had been operating at 0.72 SMYS. Recently, Boardwalk announced the sale of an additional 156 MMcf/d of capacity on the Haynesville Project under a 15-year agreement. The additional capacity was contingent upon receiving approval to operate at 0.80 SMYS. The East Texas Pipeline originates near Carthage, TX, and proceeds to Harrisville, MS. The Southeast Expansion project originates near Harrisville, MS, and extends to an interconnect with Transcontinental Gas Pipe Line Co. in Choctaw County, AL (Transco Station 85). The Gulf Crossing Pipeline originates near Sherman, TX, and proceeds to the Perryville, LA, area. Boardwalk had previously received authorization to operate the pipelines at standard operating pressures (see Daily GPI, July 29).

Williams’ Northwest Pipeline GP has received authorization from the Federal Energy Regulatory Commission (FERC) to place its 24-inch diameter Colorado Hub Connection into service, it said. The 26.4-mile pipeline and related facilities connect the Meeker/White River Hub, a regional production area hub, with the Northwest Pipeline mainline south of Rangely, CO. The project will provide approximately 360,000 Dth/d of firm service on Northwest’s mainline to delivery points as far south as Ignacio, CO. At Ignacio Northwest interconnects with El Paso Natural Gas and Transwestern Pipeline Co. The cost of the project was approximately $60 million. “Completion of the Colorado Hub makes it possible for us to connect the Piceance Basin supplies with markets in the western U.S. through Northwest’s existing mainline system,” said Phil Wright, president of Williams’ gas pipeline business. In August 2007 Northwest conducted an open season for the project and filed an application for a FERC certificate in September 2008. Williams Pipeline Partners LP owns a 35% interest in Northwest Pipeline GP.
