The Federal Energy Regulatory Commission on Sept. 29 issued a notice about a Sept. 15 application from Texas Eastern Transmission LP for a certificate of public convenience and necessity to construct its Marshall County Mine Panel 17W Project.
Texas Eastern said this project is designed to ensure the safe and efficient operation of Texas Eastern’s existing pipeline facilities during the longwall mining activities planned by Marshall County Coal Co. beneath Texas Eastern’s pipelines in Marshall County, West Virginia. Texas Eastern proposes to excavate, elevate, and/or replace certain sections of four different pipelines and appurtenant facilities.
Within 90 days of this notice the commission staff will either: complete its environmental assessment (EA) and place it into the commission’s public record; or issue a Notice of Schedule for Environmental Review.
The application said that Marshall County Coal has informed Texas Eastern that longwall mining activities are expected to take place between September 2017 and December 2017 in the area of Texas Eastern’s pipelines. Due to the risk to the integrity of the pipelines and the potential interruption of service that longwall mining activities could introduce, including possible buckling, Texas Eastern designed the Marshall County Mine Panel 17W Project to protect Texas Eastern’s facilities that traverse the surface of Marshall Coal’s mine. The project also is designed to ensure that certificated levels of service are maintained for the duration of the longwall mining activities.
Texas Eastern is proposing to begin the activities, including tree clearing activities, related to the elevation and replacement of its pipelines in March 2017 and anticipates completing these activities prior to the Sept. 1, 2017, anticipated start date of longwall mining activities which will then continue beneath the pipelines through the fall of 2017. Reinstallation of the pipeline sections is expected to begin in April 2018. During the reinstallation process, the applicable pipeline sections will be taken out of service, returned below-ground to their original alignments, and hydrostatically tested again before being returned to service. The project is expected to be completed and all buried pipeline sections returned to service by Sept. 1, 2018.
Marshall County Coal is a Murray Energy company, and this mine (formerly known as McElroy) is one of the Pittsburgh-seam longwall operations in northern West Virginia that Murray bought earlier this decade from CONSOL Energy.
