Justia Environmental Law Opinion Summaries

The plaintiffs, projects focused on protecting water quality, brought a suit against a clay recycling facility located near Temescal Creek in California, alleging violations of stormwater-permit requirements under the Clean Water Act. The facility, operated by Corona Clay Company, discharged stormwater into Temescal Creek, a tributary of the Santa Ana River. Regulatory authorities had previously issued violation notices to Corona, but no enforcement action was taken by the state. The plaintiffs sought relief for both substantive discharge violations and procedural violations such as monitoring and reporting.The United States District Court for the Central District of California initially found in favor of Corona following a trial. The Ninth Circuit Court of Appeals reversed and remanded, citing an intervening Supreme Court decision, County of Maui v. Hawaii Wildlife Fund, which expanded the scope of the Clean Water Act to include indirect discharges that are the “functional equivalent” of direct discharges. On retrial, the plaintiffs prevailed, and Corona was assessed significant penalties. After the Supreme Court’s Sackett v. EPA decision, which narrowed the definition of “waters of the United States,” Corona moved to dismiss for lack of subject-matter jurisdiction and alternatively sought a new trial. The district court denied both motions, holding that the jurisdictional requirement was met and the issue of whether Temescal Creek qualified as a water of the United States had been conceded.The United States Court of Appeals for the Ninth Circuit affirmed the district court’s denial of Corona’s post-judgment motion to dismiss for lack of subject-matter jurisdiction, holding that whether a waterbody qualifies as a “water of the United States” is a merits question, not a jurisdictional one. However, it reversed the denial of Corona’s motion for a new trial under Federal Rule of Civil Procedure 59, concluding that the intervening Sackett decision rendered a previously foreclosed issue viable. The panel remanded for further proceedings to determine, under Sackett’s standard, whether Temescal Creek is a water of the United States. View "INLAND EMPIRE WATERKEEPER V. CORONA CLAY COMPANY" on Justia Law

A group of residents in the District of Columbia challenged amendments to the District’s Comprehensive Plan, a document that guides land use decisions. The 2021 amendments, enacted after a lengthy planning and public comment process, increased land use densities in certain neighborhoods, prompting concerns among residents about potential harms such as increased risk of displacement, infrastructure strain, and changes to neighborhood character. The residents sued, alleging that the Mayor’s Office of Planning failed to produce an adequate environmental assessment and did not give proper consideration to their Advisory Neighborhood Commissions.The Superior Court of the District of Columbia reviewed the complaint and dismissed it with prejudice, finding that none of the plaintiffs had standing. The court determined that the alleged injuries were too hypothetical and amounted to generalized grievances rather than concrete, particularized harm. Additionally, it concluded that there was no causal link between the Office of Planning’s actions and the claimed injuries, and that the injuries were not redressable because the court could not prevent implementation of the enacted Plan.On appeal, the District of Columbia Court of Appeals agreed that the appellants lacked standing, holding that none had alleged an injury-in-fact that was sufficiently concrete or imminent. The court explained that most harms were generalized or speculative and not tied to any specific development project at the time the Plan was enacted. However, the appellate court found that the Superior Court erred in dismissing the suit with prejudice; dismissals for lack of standing should be without prejudice. The Court of Appeals affirmed the dismissal for lack of standing but remanded for the trial court to revise the judgment to reflect that it is without prejudice. View "Booth v.

The plaintiff, a limited partnership, initiated an action in 2019 against the State of Connecticut and its Commissioner of Energy and Environmental Protection, alleging unreasonable delays in processing applications for reimbursement under the underground storage tank petroleum clean-up program. The plaintiff sought a writ of mandamus to compel payment for approved claims and adjudication of pending claims, as well as damages for alleged constitutional violations and unlawful taking of property.The Superior Court dismissed the action for lack of subject matter jurisdiction, citing sovereign immunity. On appeal, the Connecticut Appellate Court reversed the dismissal as to the mandamus claim and remanded for further proceedings, but affirmed dismissal of the damages claims. Following remand, the plaintiff amended its complaint to seek only a writ of mandamus for payment of approved claims. The trial court denied this request, finding the plaintiff did not show a complete and immediate right to payment. The Appellate Court affirmed, and the plaintiff was granted certification to appeal to the Supreme Court of Connecticut.After certification was granted, the legislature enacted Public Act 25-168, which cancelled all applications under the program, transferred remaining funds to the state’s general fund, and repealed the statutory scheme governing the program. The Supreme Court of Connecticut concluded that these legislative actions rendered the plaintiff’s appeal moot, as no practical relief could be granted. The court dismissed the appeal and vacated the judgments of the Appellate Court and the trial court pertaining to the writ of mandamus, but declined to vacate prior judgments in unrelated claims from earlier proceedings.

The Environmental Protection Agency (EPA) conducted a periodic review of the national ambient air quality standards (NAAQS) for nitrogen oxides, sulfur oxides, and particulate matter, as required by the Clean Air Act. After an extensive eleven-year process, EPA decided to retain the existing standards for nitrogen oxides and particulate matter, while lowering the secondary standard for sulfur oxides. EPA also issued a memorandum explaining its view that the new rule would not change air quality or emissions and thus would have no effect on endangered species or their habitats.Previously, EPA published its proposed rule in April 2024, followed by the final rule in December 2024. The agency’s no-effect determination stated that the revisions would not trigger additional emissions reductions or affect listed species. The Center for Biological Diversity (CBD) challenged EPA’s rule, arguing that the agency violated the Endangered Species Act (ESA) by failing to consult with federal wildlife agencies before issuing the rule. CBD asserted that ongoing and cumulative pollutant effects could harm species, and that EPA’s effects determination was both arbitrary and untimely.The United States Court of Appeals for the District of Columbia Circuit reviewed the case. The court found that CBD had standing to bring the challenge, but ultimately determined that EPA’s no-effect finding was reasonable and not arbitrary or capricious. The court explained that the rule would not cause any changes to air quality or emissions, and thus would not trigger consultation obligations under the ESA. The court also held that EPA’s timing of the effects determination was appropriate under regulatory requirements. The main holding is that EPA reasonably determined the rule would have no effect on protected species or critical habitat, and the petition for review was denied.

Venture Global CP2 LNG and Venture Global CP Express sought authorization from the Federal Energy Regulatory Commission (FERC) to construct and operate a liquefied natural gas (LNG) export terminal and an 85-mile pipeline in Louisiana. FERC’s review included extensive environmental analysis in compliance with the National Environmental Policy Act (NEPA), resulting in an Environmental Impact Statement (EIS) and a Supplemental EIS (SEIS). Both assessments concluded that, with recommended mitigation measures, the project’s environmental impacts, including those on air quality and the commercial fishing industry, would not be significant.Individuals and advocacy groups challenged FERC’s authorization, raising eleven alleged errors under the Natural Gas Act (NGA) and NEPA. After FERC’s initial order in 2024, the challengers sought rehearing. FERC partially granted rehearing to address concerns raised by recent D.C. Circuit decisions and directed additional environmental review, which led to the SEIS. The SEIS found no exceedances of relevant air quality standards for the terminal and compressor station. FERC reaffirmed its authorization in 2025, and subsequent rehearing requests were denied. The challengers then petitioned the United States Court of Appeals for the District of Columbia Circuit for review.The United States Court of Appeals for the District of Columbia Circuit held that FERC’s interpretation and application of the NGA was lawful and not arbitrary, emphasizing the presumption in favor of terminal authorization under Section 3, absent an affirmative showing of inconsistency with the public interest. The court found FERC’s NEPA analysis reasonable, deferring to FERC’s use of established air quality standards and its reliance on expert agency data. The court also upheld FERC’s treatment of cumulative impacts and harm to commercial fisheries as sufficiently addressed and explained. The petitions for review were denied in full.

The Export-Import Bank of the United States (Eximbank) agreed to lend up to $5 billion to support the development of a major liquefied natural gas project in Mozambique. After insurgent attacks in the project area halted operations, Eximbank approved an amendment in 2025 to allow disbursement of funds on a revised schedule. Two environmental organizations, Friends of the Earth U.S. and Justiça Ambiental, argued that Eximbank’s actions violated statutory requirements by failing to provide a notice-and-comment period or disclose certain economic and environmental analyses before approving the amendment. The organizations claimed the project’s restart would intensify local conflict, cause environmental harm, and impair their ability to serve affected communities.The United States District Court for the District of Columbia denied the plaintiffs’ motion for a preliminary injunction. The court found that the plaintiffs were unlikely to show standing for most of their claims, including lack of a notice-and-comment period and diversion of organizational resources. However, the district court concluded they had a substantial likelihood of standing on an informational injury theory relating to Eximbank’s failure to provide environmental information, but determined the plaintiffs had not shown a likelihood of success on the merits for any of their claims.The United States Court of Appeals for the District of Columbia Circuit reviewed the denial of the preliminary injunction. The court affirmed the district court’s decision. It held that the plaintiffs failed to establish organizational standing because their alleged injuries were either not particularized or too attenuated. The court concluded the plaintiffs demonstrated a substantial likelihood of informational standing for environmental information but failed to show a likelihood of success on the merits, because NEPA does not apply to projects with effects entirely outside U.S. jurisdiction and Eximbank’s disclosure obligations were not triggered. The denial of the preliminary injunction was therefore affirmed. View "Friends of the Earth v. Export-Import Bank" on Justia Law

Two synthetic chemicals, PFOA and PFOS—members of the PFAS group often called “forever chemicals”—have been widely used since the 1940s and are highly persistent in the environment and the human body. Scientific studies have linked exposure to these chemicals to serious health conditions, including cancer and developmental delays. In 2024, the Environmental Protection Agency (EPA) designated PFOA and PFOS as “hazardous substances” under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), which governs the cleanup of hazardous substances and allows for cost recovery from polluters.This designation was challenged by seven industry groups representing entities that use, transport, or discharge PFOA and PFOS. The challengers argued that EPA misinterpreted CERCLA’s standard for designating hazardous substances, failed to provide adequate notice regarding its cost-benefit analysis, and acted arbitrarily and capriciously by regulating in the face of scientific and economic uncertainties. They also argued that the designation violated the Administrative Procedure Act and constitutional doctrines.The United States Court of Appeals for the District of Columbia Circuit reviewed the case. The court found that EPA acted within its statutory authority: CERCLA allows EPA to designate substances that “may present substantial danger” upon release, and the agency’s interpretation of “may” as requiring only the possibility, rather than certainty, of substantial harm was consistent with statutory text and precedent. The court concluded that EPA provided adequate notice and opportunity for public comment regarding its cost-benefit analysis, and that the agency’s rulemaking was neither arbitrary nor capricious. The court also held that the agency’s actions did not violate constitutional doctrines. Accordingly, the court denied the petitions for review, upholding EPA’s designation of PFOA and PFOS as hazardous substances. View "Chamber of Commerce v. EPA" on Justia Law

Acadia Aqua Farms applied in 2019 for a twenty-year aquaculture lease in Eastern Bay, Maine, proposing to cultivate blue mussels using floating equipment, including a harvesting machine and a permanently moored storage raft. The company planned to operate seasonally, with routine maintenance and harvesting involving mechanized equipment. The Department of Marine Resources held a public hearing, allowing testimony from Acadia, intervenors such as Friends of Eastern Bay, and the public. Concerns were raised about noise impacts on nearby research facilities, especially the Mount Desert Island Biological Lab.After review, the Commissioner of the Maine Department of Marine Resources approved the lease in October 2024, but reduced its area from the requested 48.11 acres to 19.71 acres and imposed several conditions aimed at mitigating noise and visual impacts. Friends of Eastern Bay challenged the decision in the Superior Court (Kennebec County), which, after transfer to the Business and Consumer Docket, affirmed the Commissioner’s decision. Friends then appealed, arguing the Commissioner lacked statutory authority, that the noise and other impacts were improperly assessed, and that the lease should have been treated as a discharge application requiring additional environmental review.The Maine Supreme Judicial Court reviewed the case and affirmed the lower court’s judgment. The Court held that the Commissioner had statutory authority to grant the lease, including approval of the storage raft as part of the aquaculture operation. It concluded that the Department’s noise mitigation requirements and factual findings were supported by substantial evidence and complied with legislative and regulatory standards. The Court also found no error in the Department’s decision not to treat the application as a discharge application, given the lack of evidence that the proposed equipment would discharge pollutants. The judgment was affirmed. View "Friends of Eastern Bay v. Department of Marine Resources" on Justia Law

In September 2024, a major fire at the Bio-Lab chemical facility in Rockdale County, Georgia, caused the release of a toxic chemical plume, resulting in an evacuation order for over 17,000 nearby residents. Many local residents subsequently sought medical attention for symptoms related to exposure to hazardous substances, including hydrogen cyanide. A group of affected residents and businesses filed a putative class action in the United States District Court for the Northern District of Georgia against Bio-Lab and related entities, alleging negligence, trespass, nuisance, and strict liability. However, the plaintiffs did not claim present physical injury; instead, they asserted an increased risk of future disease and sought, among other remedies, an injunction requiring the creation of a defendant-funded medical monitoring program.The defendants moved to dismiss the request for equitable relief, arguing that Georgia law does not permit medical monitoring as a remedy absent allegations of present physical injury. The federal district court, finding Georgia law unclear on this issue, certified two questions to the Supreme Court of Georgia: whether a plaintiff exposed to toxic substances without present physical injury may obtain equitable relief in the form of medical monitoring, and if so, what standard applies.The Supreme Court of Georgia responded that, under Georgia law, the availability of equitable relief depends on whether the plaintiff has suffered a legally cognizable injury and whether that injury meets the established criteria for equitable relief, including the absence of an adequate remedy at law and the imminence of harm. The court declined to decide whether the specific facts of this case warranted such relief, leaving that determination to the district court. Additionally, the court concluded that the precise form and scope of equitable relief in a federal diversity case is likely governed by federal law, not state law. The certified questions were thus answered only in part. View "BIO-LAB, INC. v. TARTT" on Justia Law

Water districts in California that received water from the federal Central Valley Project sought to convert their water service contracts into repayment contracts under the Water Infrastructure Improvements for the Nation (WIIN) Act. This conversion allowed the districts to prepay construction costs in exchange for contracts that would last indefinitely, rather than for a set term. The Bureau of Reclamation, which manages the Central Valley Project, converted 67 contracts upon request from water districts, modifying only the payment terms and leaving other contractual rights unchanged. The Bureau did not conduct contract-specific environmental review under the National Environmental Policy Act (NEPA) or consult with wildlife agencies under the Endangered Species Act (ESA) before making these conversions.The Center for Biological Diversity and other plaintiffs challenged the Bureau’s actions in the United States District Court for the Eastern District of California. They argued that the Bureau was required to undertake NEPA review and ESA consultation before converting each contract, because the conversions would impact the environment and protected species in the Bay-Delta ecosystem. The district court compelled joinder of the affected water districts and granted summary judgment to the Bureau and the water districts. The court found that the WIIN Act imposed a mandatory duty on the Bureau to convert contracts upon request, and that the Bureau lacked discretion to alter terms for environmental protection, so NEPA and the ESA did not apply.On appeal, the United States Court of Appeals for the Ninth Circuit affirmed the district court’s judgment. The court held that section 4011(a) of the WIIN Act requires the Bureau to convert water service contracts upon request, permitting only changes related to payment structure and not to other contractual rights. Because the conversions are nondiscretionary, the Bureau is not required to conduct NEPA review or ESA consultation. The Ninth Circuit also found that this interpretation does not violate the WIIN Act’s savings clauses. View "CENTER FOR BIOLOGICAL DIVERSITY V. UNITED STATES BUREAU OF RECLAMATION" on Justia Law
