On June 6, 2025, the D.C. Circuit ruled in Appalachian Voices et al. v. FERC that the Federal Energy Regulatory Commission’s (FERC) approval of an extension of the construction deadline for Mountain Valley Pipeline, LLC’s (MVP) MVP Southgate Project (the “Southgate Project”) was permissible, denying environmental groups’ petitions for review. This case potentially forecasts future judicial treatment of agency action in the aftermath of the Loper Bright v. Raimondo decision, and signals how courts may treat future challenges aimed at delaying development in light of recent curtailment of the National Environmental Policy Act (NEPA). Read More »

On June 18, 2025, the Supreme Court decided EPA v Calumet Shreveport Refining, LLC et al., and its companion case Oklahoma et al. v. EPA, clarifying the tripartite framework for determining venue in Clean Air Act (“CAA” or “Act”) litigation.  Looking at the CAA's venue provision (42 U.S.C. 7607(b)(1)), the Court explained that if a challenge is to an “nationally applicable” EPA action the challenge should be directed to the U.S. Circuit Court of Appeals for the D.C. Circuit and the matter ends there.  But, if the challenge is to a “locally or regionally applicable” EPA action, then typically those challenges belong in the relevant regional Circuit Court.  However, when a “locally or regionally applicable” action falls within the “nationwide scope or effect” exception, which requires the action be (1) “based on a determination of nationwide scope or effect” and (2) accompanied by an EPA finding to the same effect, the Court instructed that the matter should be routed back to the D.C. Circuit.  Applying this understanding of CAA's venue provision, the Court reached different conclusions in Calumet and Oklahoma, finding respectively that the “nationwide scope or effect” exception applied in one instance and not in the other.

On June 20, 2025, the Supreme Court issued it opinion in Diamond Alternative Energy v. EPA, holding fuel producers had standing—and had specifically demonstrated redressability—to challenge California-specific regulations EPA approved under the Clean Air Act.  The Court’s opinion  reversing and remanding to the D.C. Circuit left the merits of the case for another day, but acknowledged that the regulations at issue may be rescinded shortly, mooting most, if not all, of the parties’ controversy. Read More »

On May 29, 2025, the Supreme Court decided Seven County Infrastructure Coalition v. Eagle County, reversing the D.C. Circuit’s determination that the Environmental Impact Statement (“EIS”) issued by the U.S. Surface Transportation Board (the “Board”) in connection with an approximately 88-mile railroad line in northeastern Utah violated the National Environmental Policy Act (“NEPA”).  Justice Kavanaugh, writing for the Court, concluded the NEPA question presented “is not close” and the Board was “absolutely correct” in declining to evaluate “environmental effects from separate projects upstream or downstream from the project at issue” in the EIS.    Read More »

In March 2024, the County of Bucks filed a controversial suit under state law against a number of large oil companies alleging the County was injured because of the companies’ deceptive conduct with respect to their impact on climate change. The Defendants filed various preliminary objections including lack of subject-matter jurisdiction, arguing that despite the County’s effort to focus the complaint on fraudulent practices, the case at bottom alleged harm from severe weather allegedly due to air emissions, which are governed exclusively by federal law. On May 16, 2025, the Bucks County Court of Common Pleas issued an opinion agreeing with the Defendants and dismissing the case entirely.  See Bucks County v. BP P.L.C., et al., No. 2024-01836 (Bucks Cty. Com. Pl. May 16, 2025). Read More »

On May 1, 2025, the United Stated District Court for the Northern District of California evaluated a settlement agreement between a long-time generator of hazardous substances, an innocent plaintiff, and the Department of Toxic Substances Control (“DTSC”), and found that it met the requirements as a good faith agreement under both the California Code of Civil Procedure and the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”).  See Maxim L Properties v. Moyer Products, Ind., 2025 WL 1261419.  The court ruled that a settlement agreement that, among other things, accounts for the “rough approximation” of liability is generally satisfactory in both California and under CERCLA.

On April 3^rd, the U.S. District Court of Colorado vacated the U.S. Army Corps of Engineers’ (“USACE”) Record of Decision, Final Environmental Impact Statement, and approval of a dredge-and-fill permit for Denver Water’s expansion project of the Gross Dam and Reservoir in Colorado and remanded the matter back to the agency.  The Court temporarily enjoined Denver Water from continuing construction on the dam pending a hearing on what is “reasonable and necessary” to ensure that the dam will be structurally safe and issued a permanent injunction prohibiting the enlargement of the Gross Reservoir.

In a decision on February 5, 2025, the Superior Court of New Jersey dismissed the Attorney General of New Jersey’s state tort claims against various energy companies seeking redress for the effects of climate change in Platkin v. Exxon Mobil Corp (N.J. Super. No. MER-L-001797-22).  Because the dispute concerned interstate and global air emissions, which implicate uniquely federal interests, the court concluded that the federal Constitutional structure requires that federal common law preempts these climate-change related tort claims.   Read More »
