Staff at the Federal Energy Regulatory Commission asked for more information before they sign off on a request to proceed with construction on an Equitrans LP natural gas pipeline expansion linked to the larger Mountain Valley pipeline.
In a Dec. 28 letter, FERC staff asked Equitrans to respond within 10 days with additional information to help staff check for compliance with environmental conditions in the commission's Oct. 13 approval order. Equitrans had filed a request Dec. 20 for a partial notice to proceed that covered most of the project.
In the October order, FERC approved the estimated $172 million Equitrans project as a piece connected to the $3.7 billion, 2-Bcf/d Mountain Valley pipeline led by EQT Midstream Partners LP. The Equitrans expansion would consist of seven miles of pipeline and a new compressor station in Pennsylvania, as well as the abandonment of an existing compressor station. Equitrans is owned by EQT Midstream.
The Mountain Valley project, a joint venture of EQT and affliates of NextEra Energy Inc., RGC Resources Inc., WGL Holdings Inc. and Consolidated Edison Inc., would bring gas about 300 miles from West Virginia to pipeline connections in Virginia for transport to markets farther downstream.
The information requested by FERC staff includes data on permanent stockpile areas near the Redhook compressor station in Greene County, Pa.; maps with the locations of all parts of the expansion project, including temporary work spaces and staging areas; survey results for drinking water sources; survey reports for water bodies and wetlands; documentation that shows the developer submitted erosion control plan to appropriate state agencies; and an analysis of horizontal directional drill noise.
