FERC to write enviro review of Columbia Gas upgrades in West Virginia and Virginia

The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) on the Line WB2VA Integrity Project, which involves abandonment, construction, and operation of facilities by Columbia Gas Transmission LLC in Hardy County, West Virginia, and Shenandoah, Page, Rockingham, and Greene counties, Virginia.

The commission will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity. a may 14 FERC notice notice opened the scoping process, which closes June 15, where the commission will gather input from the public and interested agencies on what should be in the EA.

Columbia proposes replacement and modification of existing equipment at numerous sites along the Line WB2VA pipeline, and at the Lost River and Bickers Compressor Stations in Hardy County, West Virginia, and Shenandoah, Page, Rockingham, and Greene counties, Virginia. The project would include the installation of pig launchers, receivers, mainline valves and other appurtenant facilities.

Also, Columbia would replace the two 20-inch-diameter pipelines beneath the South Fork of the Shenandoah River with a new 24-inch-diameter pipeline. To maintain service during the proposed pipeline replacement activities, Columbia would install temporary fittings and temporary bypass piping. Once the installation of the new segment of pipeline is complete and tied-in to the existing WB2VA pipeline, the temporary bypass piping would be removed.

This project is part of Columbia’s multi-year modernization program developed to address its aging infrastructure. The existing mainline valves do not permit the use of smart pigs as an inspection tool, and the two existing 20-inch-diameter pipelines crossing the South Fork of Shenandoah River create a similar barrier. The project modifications would create a continuous, 24-inch-diameter pipeline between Columbia’s existing Lost River and Bickers Compressor Stations that would allow for smart pig inspections.
