The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) on the Access South, Adair Southwest and Lebanon Extension Projects proposed by Texas Eastern Transmission LP, which would provide incremental pipeline transportation service from Appalachia natural gas supply basins to markets in the Midwest and Southeast.
The commission said in an Aug. 11 notice that it will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity. It will take scoping comments on what should be covered in the EA until Sept. 10.
The planned pipeline facilities include 19.9 miles of 36-inch diameter pipeline loop in three segments, most of which would be either within or adjacent to Texas Eastern’s existing rights-of-way in Meigs, Athens, Noble, Monroe counties, Ohio. Proposed modifications to aboveground facilities would include the installation of new compression and additional modifications necessary to allow for bidirectional flow, increased horsepower requirements, and meter reversals at thirteen existing compressor stations which are expected to be located primarily within Texas Eastern’s current footprint.
At the Five Points Compressor Station in Pickaway County, Ohio, Texas Eastern would install a new 10,000 horsepower (hp) electric compressor and would abandon in-place three 2,000 hp electric compressor units. A new 16,875 hp electric compressor would be added at the Tompkinsville Compressor Station in Monroe County, Kentucky.
Planned modifications at thirteen existing compressor station sites would include piping modifications to accommodate bi-directional flow capability along Texas Eastern’s existing mainline. In addition two pig launcher/receivers would be relocated and two new pig launcher/receivers would be installed in Monroe County, Ohio.
Texas Eastern on March 13 put these three projects into the pre-application environmental review process at FERC. It is seeking environmental review for the Access South Project, Adair Southwest Project and Lebanon Extension Project. Upon completion of the pre-filing review, Texas Eastern will file an application with the commission for authorization to construct the projects.
These projects are designed to provide incremental pipeline transportation service from the Appalachia area natural gas supply basins to different markets in the Midwest and Southeast. The target in-service date for each of the projects is Nov. 1, 2017. The projects will create additional firm pipeline capacity necessary to deliver, in aggregate, 700,000 dekatherms per day (Dth/d) of natural gas on a long-term basis.
- The Access South Project would provide up to 320,000 Dth/d of capacity to transport supply from a receipt point in Uniontown, Pa., to delivery points in Texas Eastern’s Access Area Zone ELA and Market Zone M1 in Attala County, Miss. (interconnections with Gulf South Pipeline Co. LP and Southern Natural Gas Co. LLC) to serve southeast U.S. markets.
- The Adair Southwest Project would provide up to 200,000 Dth/d of capacity to transport supply from a receipt point in Uniontown West, Pa., to delivery points in Texas Eastern’s Market Zone M2 in Adair County, Ky. (interconnection with Columbia Gulf Transmission LLC) to serve lower U.S. Midwest markets.
- The Lebanon Extension Project would provide up to 180,000 Dth/d of capacity to transport supply from receipt point(s) in Pennsylvania and/or Ohio to delivery points in Market Zone M2 in or near Lebanon, Ohio.
