Columbia Gas Transmission has filed an application with the Federal Energy Regulatory Commission for a natural gas pipeline project in West Virginia and Virginia.

Parent companies Columbia Pipeline Group Inc. and Columbia Pipeline Partners LP said Friday that Columbia Gas is proposing to construct and operate two compressor stations, replace 26 miles of pipeline along existing corridors and built 2.9 miles of new pipeline in the two states.

If it receives regulatory approval, construction on the $850 million WB Xpress Project would begin in 2017 and start deliveries in the second half of 2018.

The companies also say in a news release that FERC has approved an application for the construction of five miles of new pipeline, modifications to existing compression facilities in Kanawha County and safety technology enhancements.
