On July 25, 2023, a Third Circuit panel rejected an environmental group’s challenge of federally approved changes to Pennsylvania’s State Implementation Plan (“SIP”),  holding that the Environmental Protection Agency (“EPA”) emissions-based analysis did not violate the Clean Air Act (“CAA”). Ctr. for Biological Diversity v. U.S. Env’t Prot. Agency, 2023 WL 471884, at *6 (3d Cir. 2023). The panel’s reasoning focused on a close statutory reading of §7410 of the CAA, which prevents EPA from approving any SIP revision that would “interfere with any applicable requirement for attainment and reasonable further progress” in reaching the National Ambient Air Quality Standards (“NAAQS”). Id. at *4. NAAQS are air quality benchmarks that each state must work toward by reducing their air pollution levels. Id. at *1. Ultimately, the Third Circuit held that Pennsylvania’s revisions did not interfere with NAAQS attainment because Pennsylvania reasonably concluded that emissions would likely decrease under the source specific requirements imposed by the revised plan. Id. at *4. Read More »

Over the last week, pre-enforcement challenges to two separate federal government actions have been dismissed for lack of standing.  In Commonwealth of Kentucky et al. v. EPA, et al., No 3:23-cv-00007-GFVT, 2023 WL 2733383 (E.D. Ky. March 31, 2023), the Honorable Gregory F. Van Tatenhove of the United States District Court for the Eastern District of Kentucky dismissed without prejudice claims brought by the Commonwealth of Kentucky (the “Commonwealth”) and private-sector plaintiffs challenging the United States Environmental Protection Agency’s (“EPA”) and Army Corps of Engineers’ rule redefining “waters of the United States” under the Clean Water Act.  Five days later, in The State of Louisiana, et al. v. Joseph R. Biden, Jr., et al., No. 22-30087, 2023 WL 2780821 (5th Cir. April 5, 2023), the Honorable Jacques L. Wiener, Jr. of the United States Court of Appeals for the Fifth Circuit dismissed states’ challenges to President Biden’s social cost of greenhouse gases established pursuant to Executive Order No. 13990 (the “Executive Order”).  Both cases demonstrate the importance of alleging sufficient harm to confer federal court jurisdiction.

In West Virginia v. EPA, the Supreme Court limited the authority of the United States Environmental Protection Agency (EPA) to reduce greenhouse gases by setting emission guidelines for existing power plants, characterizing the energy generation shifting strategy proposed in the Clean Power Plan (CPP) as an overreach of the agency’s power. In a 6-3 decision, with the three liberal justices dissenting, the Court held that the authority to adopt a regulatory program that would significantly alter how the nation’s energy is generated fell under an “extraordinary case” of the major questions doctrine. West Virginia v. EPA 597 U. S. ____ (2022). The major questions doctrine requires that a federal agency have “clear congressional authorization” when acting on issues of great “economic and political significance.” Id. (citing Utility Air Regulatory Group v. EPA, 573 U. S. 302, 324). Read More »

On May 17, 2021, the Supreme Court vacated an appellate court decision which had remanded to state court an action seeking to hold petroleum companies liable for the effects of climate change, finding that the appellate court impermissibly restricted the scope of its review of a district court’s order. Although, as noted by the Supreme Court, “[t]he only question before us is one of civil procedure,” the case of BP P.L.C. v. Mayor and City Council of Baltimore, Docket No. 19-1189 (May 17, 2021) may have a profound practical impact on ongoing environmental litigation. Read More »

On February 22, 2021, the D.C. Circuit granted the Environmental Protection Agency’s (“EPA”) motion to stay the vacatur of the Trump administration’s Clean Power Plan Repeal Rule until EPA conducts further rulemaking on the issue in the case of American Lung Association v. EPA, No. 19-1140 (D.C. Cir., Feb. 22, 2021). This decision marks the latest action in the ongoing efforts by EPA and states to regulate greenhouse gas emissions; particularly in terms of carbon emissions from currently existing power plants. For additional background, please see previous MGKF blog on this topic here.  Read More »

On January 19, 2021, the U.S. Court of Appeals for the D.C. Circuit vacated and remanded the Trump administration’s Affordable Clean Energy Rule (“ACE Rule”), which itself was a rollback of the Obama administration’s Clean Power Plan (“CPP”); once again reshaping the heart of American climate policy. American Lung Association v. EPA, No. 19-1140 (D.C. Cir., Jan. 19, 2021). The CPP and ACE Rule both sought to regulate greenhouse gas (“GHG”) emissions from existing stationary sources but used highly divergent interpretations of the Clean Air Act (“CAA”) to do so. In making its ruling, the Court called the Trump Environmental Protection Agency’s interpretation of the CAA a “fundamental misconstruction” of the statute and provided a lengthy analysis of its findings. Id. at 16. The Court ultimately held that because the Environmental Protection Agency (“EPA”) based the ACE Rule “on an erroneous view of the law” (as opposed to having based the ACE Rule on a valid exercise of agency discretion), the court had no choice but to vacate the rule and remand it to the EPA for additional interpretation. Id. at 46. Because President Biden has described climate change as the “existential threat of our time,” the Biden EPA will likely use this opportunity to draft new rulemaking regarding the regulation of GHG emissions.
