FERC Issues Notice of Application for Appalachia to Market III Project

Strategic Insights -

The Federal Energy Regulatory Commission (FERC) has issued a Notice of Application for the Appalachia to Market III Project, a natural gas pipeline project that aims to improve reliability and provide incremental transportation capacity. The project, submitted by Texas Eastern Transmission, LP, would transport approximately 32,000 dekatherms per day from the Appalachian supply basin in Southwest Pennsylvania to delivery points in Pennsylvania. FERC has identified Commission staff's intention to prepare an environmental assessment (EA) for the project, which will be issued for a 30-day comment period.

Key Takeaways:

  • The Appalachia to Market III Project would provide approximately 32,000 dekatherms per day of natural gas transportation capacity from the Appalachian supply basin to Pennsylvania.
  • The project would improve reliability on Texas Eastern's system and provide incremental transportation capacity for precedent agreements with two local gas distribution companies.
  • FERC has identified Commission staff's intention to prepare an environmental assessment (EA) for the project, which will be issued for a 30-day comment period.
  • The EA will be used to identify any potential environmental impacts of the project and determine the necessity of additional studies.
  • Texas Eastern estimates that the project would require the construction and abandonment of approximately 2 miles of pipeline, as well as the modification of the Bedford Compressor Station.
  • The project would also involve the installation of new equipment, including a new pig receiver, 36-inch-diameter valve, and 30-inch-diameter crossover.
  • FERC has established a 90-day deadline for federal authorizations and other approvals necessary for the project.
  • The Commission's deadline applies to decisions made by other federal agencies and state agencies acting under federally delegated authority.

Statistics:

  • 32,000 dekatherms per day: the proposed capacity of the Appalachia to Market III Project.
  • 90 days: the timeframe for all necessary reviews and final decision on federal authorizations, permits, and approvals.
  • 30 days: the comment period for the environmental assessment (EA) for the project.
  • 2 miles: the length of pipeline that would be constructed and abandoned as part of the project.
  • 36-inch-diameter: the proposed diameter of the new pipeline to be installed as part of the project.
  • 30-inch-diameter: the proposed diameter of the new crossover to be installed as part of the project.
