The United States District Court for the Western District of Louisiana, Lake Charles Division, on August 22, 2024 issued an injunction barring the United States Environmental Protection Agency (EPA) and the United States Department of Justice (DOJ) from enforcing regulations based on Title VI of the Civil Rights Act, 42 U.S.C. 200d, et seq., in the State of Louisiana (the “State”). The ruling in State of Louisiana v. US Environmental Protection Agency, et al., No. 2:23-CV-00692, 2024 WL 3904868, at *1 (W.D. La. Aug. 22, 2024), effectively prohibits these federal agencies from implementing regulations that implicate Title VI’s disparate impact prohibition.   Read More »

In the wake of the Supreme Court’s decision in Loper Bright Enters. v. Raimondo, 244 S.Ct. 2244 (2024), the general breadth and scope of agency decision-making has been called into question. In its recent decision, Huntsman Petrochemical LLC v. EPA, No. 23-1045, 2024 WL 3763355 (D.C. Cir. Aug. 13, 2024), the D.C. Circuit has made it clear that where statutory interpretation is not implicated, the Court will continue to afford EPA’s conclusions involving technical expertise a significant degree of deference. While neither the parties nor the Court attempted to address or reference Loper Bright, the Court articulated a clear standard applicable to agency actions involving statistical and modeling analyses: the Court will examine each step of an agency’s analysis to satisfy themselves that the agency has not “departed from a rational course.” Only where a statistical model “bears no rational relationship to the characteristics of data to which it was applied” will agency action be deemed arbitrary and capricious. Accordingly, regulated entities should be aware that the concept of deference lives on when challenging agency decision-making, even in the wake of the fall of Chevron Deference. Read More »

On July 18, 2024, in Shirley v. Pennsylvania Legislative Reference Bureau, No. 85 MAP 2022, 2024 WL 3450536 (Pa. July 18, 2024), the Pennsylvania Supreme Court reversed the denial of three nonprofit organizations’ application to intervene in the litigation challenging the Pennsylvania Department of Environmental Protection (PADEP) regulation implementing Pennsylvania’s participation in the Regional Greenhouse Gas Initiative (the RGGI Regulation).  After rejecting several arguments regarding the appealability of the order denying intervention, the Court found that the nonprofits’ interest in defending the RGGI Regulation under the Pennsylvania Constitution’s Environmental Rights Amendment (ERA) was not adequately represented by the PADEP and therefore the lower court erred in denying intervention.  Because of this ruling, the three nonprofit organizations (Citizens for Pennsylvania’s Future, Clean Air Council, and the Sierra Club) (Nonprofits) are now able to pursue an appeal of the Commonwealth Court’s final order permanently enjoining the RGGI Regulation from going into effect.  Read More »

In a 5-4 decision, a divided Supreme Court stayed the enforcement of the Environmental Protection Agency’s (“EPA”) Federal Implementation Plan (“FIP”) holding that the emission control measures set to be used in upwind states to improve ozone levels in downwind states was arbitrary and capricious. Ohio et al. v. Env’t Prot. Agency, No. 23A349, No. 23A350, No. 23A351, No. 23A384, 2024 WL 3187768 at *11 (S. Ct. June 27, 2024). The Court reasoned that EPA’s FIP rested on the assumption that all upwind states would adopt emission-reduction measures to ensure effective downwind air quality improvements. EPA, however, failed to reasonably explain if the FIP would be operable if some upwind states fell out of the plan. In the short term, the stay provides temporary relief to industry groups and states that challenged various aspects of the FIP in the D.C. Circuit; in the long term, the Court’s ruling spells trouble for the FIP’s efficacy if and when federal courts rule on the merits of the rule’s legality.      Read More »

On September 14, 2023, in Conservation Law Foundation v. Academy Bus, a Massachusetts District Court held that the members of the Conservation Law Foundation (the “Foundation”) lacked standing to challenge the idling of buses under the Clean Air Act (“CAA”).  Conservation Law Found. v. Acad. Express, LLC., No. 20-10032-WGY, 2023 WL 5984517, at *1 (D. Mass. Sept. 14, 2023). Specifically, the court held that simply breathing in polluted air, without any concrete injury that is fairly traceable to the defendant, is not sufficient to prove an actual injury under the CAA.

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 »

In Sinclair Wyoming Refining Company, LLC v. United States Environmental Protection Agency, No. 22-9530 (10th Cir. July 5, 2023),  the Honorable Scott M. Matheson, Jr. of the United States Court of Appeals for the Tenth Circuit dismissed a petition for review filed by Sinclair Wyoming Refining Company, LLC (“Sinclair”) of an email from the United States Environmental Protection Agency (“EPA”) for lack of jurisdiction because it was not a final agency action.  Sinclair applied for a hardship exemption from EPA’s Renewable Fuel Standards for compliance year 2018 and, when EPA did not immediately respond, submitted Renewable Identification Numbers (“RINs”) in compliance with the regulations.  Sinclair’s application was initially denied by EPA and later reconsidered and approved.  Sinclair asked EPA in two separate emails to return the RINs that it had submitted for calendar year 2018.  In April 2022, the Director of EPA’s Fuel Compliance Center responded to Sinclair’s email, stating, in relevant part, that “the 2018 RINs [would] not be returned… .”  Sinclair filed the petition for review of EPA’s April 2022 email.

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.

EPA’s Clean Air Act (“CAA”) rulemakings directed at power plants are often the target of regulatory challenges in federal court.  EPA’s latest rulemaking regulating Hazardous Air Pollutant (“HAP”) emissions from coal- and oil-fired electric utility steam generating units (“EGUs”) is unlikely to be an exception. 88 Fed. Reg. 13956 (Mar. 6, 2023).  In the now final rule, EPA has revoked an earlier action taken in 2020, in which the agency declined to regulate HAP emissions from EGUs after comparing the costs of compliance relative to the benefits of regulation, relying at the time on the Supreme Court’s decision in Michigan v. EPA, 576 U.S. 743 (2015).  Id. at 13957; see also 85 Fed. Reg. 31286. Now, just three years later under a new administration, the agency has backtracked, finding that it is appropriate and necessary to regulate HAP emissions from EGUs based on new data regarding the costs and benefits of regulating HAP emissions.  EPA claims that its latest decision is actually more in line with the statutory factors identified in Michigan for determining whether it is “appropriate and necessary” to regulate HAP emissions from EGUs under the CAA.

That federal agencies enjoy numerous advantages in defending against legal challenges to their administrative decision-making is a fact of administrative law.  But these advantages extend beyond the favorable standards of review that typically apply to their decisions.  An agency can, for example, sometimes short circuit what might be a meritorious appeal by seeking a “voluntary remand” from the Court, thereby potentially affording itself more control over any reconsideration while avoiding creating unfavorable precedent.  As a reminder of this, the Sixth Circuit recently held that EPA was entitled to reconsider one of its Clean Air Act (CAA) rulemakings, namely its decision to remove the air nuisance rule (ANR), a broad standard that generally prohibited nuisance emissions that endangered the “health, safety, or welfare of the public,” from Ohio’s State Implementation Plan (SIP), without the Court vacating EPA’s underlying decision.  Sierra Club et al. v. EPA, No. 21-3057, 2023 WL 1873168, at * 1 (6th Cir. Feb. 10, 2023).    Read More »
