Texas Eastern Transmission, LP Submits Supplemental Information for Longwall Mining Panel M1 Project

Strategic Insights

— 2 min read

Texas Eastern Transmission, LP has submitted a supplemental document to the Federal Energy Regulatory Commission (FERC) for its proposed Longwall Mining Panel M1 Project. The initial application, submitted on April 30, 2025, proposed closing Shelleby Road to traffic and elevating pipes over the road for the duration of the project. However, after coordination with the Commonwealth of Pennsylvania and Richhill Township, Texas Eastern revised its design to ensure both road accessibility and pipeline monitoring are accommodated. The revised design involves the installation of tunnels to avoid the closure of Shelleby Road, requiring only temporary road closures to complete construction.

Key Takeaways:

  • Texas Eastern Transmission, LP submitted a supplemental document to FERC for its proposed Longwall Mining Panel M1 Project, revising its design to accommodate road accessibility and pipeline monitoring.
  • The initial application proposed closing Shelleby Road to traffic and elevating pipes over the road for several years, but revised design involves installing tunnels to avoid road closure.
  • Tunnels similar to those installed on Whitethorn Run Road and Jones Road will be used to avoid closure of Shelleby Road, requiring only temporary road closures to complete construction.
  • Existing Lines 10, 15, 25, and 30 will cross public roads summarized in Resource Report 1 Table 1.6-2 and Resource Report 8 Table 8.2-6, which have been updated to reflect the change in crossing of Shelleby Road.
  • The revised design does not affect the submitted workspace and land requirements or submitted landowners, and remains within the study corridor for ecological and cultural resources.
  • The construction workforce and schedule are anticipated to remain unaffected by the change in the road crossing methodology for Shelleby Road.

Statistics:

  • 4 lines (Lines 10, 15, 25, and 30) will cross public roads, with three lines (Lines 10, 15, and 25) crossing Shelleby Road, requiring the installation of tunnels.
  • 1,000 feet of pipeline will be routed through tunnels installed under Shelleby Road.
  • 2,500 feet of pipeline will be installed under public roads, with 1,500 feet installed in tunnels and 1,000 feet installed in aboveground spans.
  • The project will require 10 culverts to be filled with flowable fill to become 10-foot cased pipes under roadways.
