Adelphia Gateway LLC v. Pennsylvania Environmental Hearing Board, No. 21-3356 (3d Cir. 2023)
Annotate this Case
The Federal Energy Regulatory Commission conditionally approved Adelphia’s application under 15 U.S.C. 717f(c), the Natural Gas Act, to acquire, construct, and operate an interstate natural gas pipeline system. As part of that project, Adelphia sought to construct a compressor station in West Rockhill Township and applied to the Pennsylvania Department of Environmental Protection (DEP) to demonstrate compliance with the Federal Clean Air Act and Pennsylvania’s Air Pollution Control Act. The DEP granted Plan Approval.
Adelphia successfully moved to dismiss appeals to the Pennsylvania Environmental Hearing Board, arguing that federal courts of appeals have original and exclusive jurisdiction over challenges to environmental permits issued by the DEP. The Commonwealth Court of Pennsylvania reversed, reasoning that administrative proceedings are not “civil actions” and that the Natural Gas Act did not preempt the Board from exercising its jurisdiction. Adelphia then filed suit in the Middle District of Pennsylvania requesting that it enjoin the Board from acting. Adelphia also appealed to the Supreme Court of Pennsylvania.
The district court dismissed Adelphia’s suit, holding that the issue preclusion doctrine bars Adelphia from bringing a federal action premised on arguments the Commonwealth Court rejected. The Third Circuit affirmed. Adelphia’s challenge impermissibly seeks to relitigate an issue decided by the Commonwealth Court.
