Staff of the Federal Energy Regulatory Commission has prepared an environmental assessment (EA) for Texas Eastern Transmission LP‘s (Tetco) proposed Idle Line 1 Abandonment project [CP17-6]. FERC staff concluded that, with appropriate mitigating measures, the project would not significantly affect the quality of the human environment. Tetco is seeking authorization to abandon in place and by removal 165 miles of Line 1 pipeline that runs from Fayette County, OH, to Greene County, PA, that were placed into idle service in 1989, including three segments of 24-inch diameter pipeline, associated lateral lines 10-L and 10-M, metering and regulating facilities and other aboveground facilities. FERC will accept comments on the EA through May 22.
