Strategic Insights -

The Federal Energy Regulatory Commission (FERC) has issued a notice of application for the Longwall Mining Panel M1 Project, a proposed natural gas pipeline facility in Greene County, Pennsylvania. The project aims to excavate, elevate, replace, and reroute segments of existing pipelines to ensure safe and efficient operation during sub-surface longwall mining activities. FERC staff will prepare an environmental assessment (EA) for the project, which will be issued for a 30-day comment period.

Key Takeaways:

  • The Longwall Mining Panel M1 Project involves excavating, elevating, replacing, and rerouting segments of existing pipelines in Greene County, Pennsylvania, to enable safe and efficient operation during sub-surface longwall mining activities.
  • The project proposes to abandon two segments of non-operational pipeline and return four pipelines to their original locations after completion of the sub-surface mining activities.
  • The project timeline anticipates construction activities to occur between 2026 and 2028.
  • FERC staff will prepare an environmental assessment (EA) for the project, which will be issued for a 30-day comment period.
  • The EA will address the potential environmental effects of subsidence from longwall mining on nearby water resources.
  • The project requires federal authorization, and the Commission has set a 90-day deadline for other federal agencies to complete their review and decision on the project.
