TVA, a federally owned power provider, undertook a project to replace aging coal-fired units at its Kingston plant in Tennessee with a new gas-fired facility, aiming to retire all coal units by 2027 and add 1,500 megawatts of reliable power. TVA considered alternatives, including continuing with updated coal units and constructing solar facilities, but ultimately chose the gas plant, entering a preliminary agreement for gas supply before completing its final environmental review. Construction began in April 2024, and six months later, three conservation groups challenged TVA’s actions, alleging violations of the National Environmental Policy Act (NEPA), particularly regarding the range of alternatives considered and alleged precommitment to the gas plant.The United States District Court for the Eastern District of Tennessee reviewed the case and granted summary judgment in part for both sides. The court found TVA met NEPA’s requirements for environmental analysis and cost evaluation but held TVA violated NEPA by considering only one feasible alternative and by precommitting to the gas plant via its supply agreement. The court vacated TVA’s Environmental Impact Statement (EIS) and Record of Decision, effectively requiring TVA to halt construction. TVA sought a stay of the vacatur order, first with the district court and then with the Sixth Circuit Court of Appeals.The United States Court of Appeals for the Sixth Circuit granted TVA’s emergency motion for a stay pending appeal. The court held TVA likely to succeed on the merits, finding the district court misinterpreted NEPA’s “range of alternatives” requirement and erred in its reading of the precommitment issue. The court also concluded that the district court likely chose the wrong remedy by vacating the EIS and Record of Decision, given the procedural nature of NEPA and the lack of viable alternatives. The stay will allow TVA to continue construction while the appeal is resolved. View "Appalachian Voices v. TVA" on Justia Law

Oklahoma was authorized by Congress in 2005 to extend its administration of federal environmental programs into Indian country, upon approval by the Environmental Protection Agency (EPA). For many years, Oklahoma did not invoke this provision. However, after the Supreme Court's decision in McGirt v. Oklahoma expanded the definition of Indian country in the state, Oklahoma requested EPA approval to apply its environmental programs to these areas. The EPA initially granted the request in 2020, then withdrew it to allow for further tribal consultation. After extensive engagement with tribal nations, the EPA issued a new approval in January 2025 with added conditions requiring tribal engagement, but subsequently rescinded those conditions in May 2025 and reissued its approval without them.The Pawnee Nation of Oklahoma challenged the EPA’s May 2025 decision in the United States Court of Appeals for the Tenth Circuit. Pawnee Nation argued that the EPA's action was unlawful because the congressional provision authorizing Oklahoma's request, § 10211(a) of the Safe, Accountable, Flexible, Efficient Transportation Equity Act (SAFETEA), had expired in 2009, that the EPA erred by refusing to impose conditions on Oklahoma’s approval, and that the EPA failed to make contemporaneous determinations of Oklahoma’s programs’ compliance with federal law.The United States Court of Appeals for the Tenth Circuit exercised exclusive jurisdiction and denied Pawnee Nation’s petition for review. The court held that § 10211(a) was unambiguous and remains active, not expired. It determined that EPA’s statutory obligation to approve Oklahoma’s request did not permit the agency to impose additional conditions, and found that EPA acted within the provision’s requirements by relying on its previous determinations that Oklahoma’s programs complied with federal law. The court affirmed EPA’s interpretation and approval. View "Pawnee Nation of Oklahoma v. Zeldin" on Justia Law

A private corporation operating oil and water injection wells in the Fruitvale Oil Field sought permission from the California Department of Conservation, Geologic Energy Management Division (CalGEM) to drill and use up to twelve new water injection wells. These wells would dispose of “produced water,” a byproduct of oil production, by pumping it into a deep aquifer. CalGEM concluded that the proposed project was not exempt from review under the California Environmental Quality Act (CEQA) and denied the required Project Approval Letter (PAL). The operator argued that the project qualified for various CEQA exemptions, including a statutory exemption for ongoing pre-CEQA private projects, as well as categorical exemptions for existing facilities and minor alterations to land.The Superior Court of Kern County granted the operator’s petition for a writ of mandate, concluding that the ongoing project exemption applied and ordering CalGEM to find the project exempt from CEQA and issue the PAL. The court also found that class 1 and class 4 categorical exemptions did not apply. The operator’s request for attorneys’ fees was struck down, as the court found it was not eligible under the relevant statute.The California Court of Appeal, Fifth Appellate District, reviewed the case. It held that substantial evidence supported CalGEM’s determination that none of the claimed exemptions applied. The court found the regulatory provision relied on for the ongoing project exemption to be invalid and, even if valid, held that CalGEM’s current approval process involved a greater degree of responsibility and control than existed before 1973, so the exemption could not apply. It further concluded that the categorical exemptions for existing facilities and minor alterations to land were inapplicable because the project involved drilling new wells to significant depths. The appellate court reversed the judgment granting the writ and dismissed the cross-appeal as moot. View "San Joaquin Facilities Management, Inc. v. Dept. of Conservation" on Justia Law

A pipeline company sought approval to construct two new segments of natural gas pipeline in Pennsylvania, requiring several environmental permits from the Pennsylvania Department of Environmental Protection (PADEP), including water quality and erosion control permits. After PADEP conditionally certified the project and subsequently issued the necessary permits following public hearings, a coalition of environmental groups (“Riverkeepers”) challenged the permit issuance, arguing that PADEP failed to ensure compliance with Pennsylvania’s water quality standards and constitutional environmental protections.The Pennsylvania Environmental Hearing Board held a five-day hearing, reviewed extensive testimony and evidence, and ultimately dismissed the Riverkeepers’ appeal. The Board found no evidence of actual environmental harm or degradation resulting from the pipeline project, rejected the claim that PADEP was required to demand specific water quality data, and credited expert testimony supporting PADEP’s permit decisions. The Board also determined that the regulatory and constitutional standards were met, and that the Riverkeepers had not demonstrated that PADEP’s actions were unreasonable or contrary to law.The United States Court of Appeals for the Third Circuit reviewed the Board’s determination under the “arbitrary and capricious” standard pursuant to the Administrative Procedure Act. The Court clarified that this was the proper standard for reviewing state agency actions taken under federal law, such as the Clean Water Act. Applying this standard, the Third Circuit found that PADEP acted reasonably in issuing the permits, adequately considered water quality and environmental data, and fulfilled its regulatory and constitutional duties. The Court rejected the Riverkeepers’ arguments regarding both regulatory and Environmental Rights Amendment violations, and denied the petition for review. View "Delaware Riverkeeper Network v. Pennsylvania Environmental Hearing Board" on Justia Law

Gateway Conservation Alliance challenged the Montana Department of Environmental Quality’s (DEQ) issuance of an opencut mining permit to TMC, Inc. for a site in Gallatin County. After DEQ approved the permit, Gateway filed an administrative appeal with the Board of Environmental Review, alleging violations of environmental statutes related specifically to the permit and site. While that administrative appeal was pending, Gateway also filed a complaint in the Gallatin County District Court, arguing that recent legislative amendments (HB 599) to the governing mining statute violated Montana’s constitutional right to a clean and healthful environment. Gateway sought a declaration of unconstitutionality, an injunction against enforcement, and vacatur of the permit.The District Court for the Eighteenth Judicial District dismissed Gateway’s complaint, holding that Gateway had failed to exhaust its administrative remedies before seeking judicial review, as required under the Montana Administrative Procedure Act (MAPA). The District Court reasoned that Gateway’s constitutional challenge was not a pure facial attack on the administrative scheme itself, but was instead tied to the specific permit at issue, and thus did not fall within any exception to the exhaustion requirement.On appeal, the Supreme Court of the State of Montana affirmed the District Court’s dismissal. The Supreme Court held that a party challenging an agency decision governed by MAPA must first complete the administrative process and obtain a final agency decision before seeking judicial review, even if the challenge includes constitutional claims. The only exception recognized is for pure facial constitutional challenges to the administrative process itself, which was not present here. The Court concluded that Gateway’s claims could be raised on judicial review after exhausting administrative remedies, but not before. The order of dismissal was affirmed.

Yellowstone County, which operates a regulated small municipal separate storm sewer system (MS4) outside the City of Billings, was required under Montana administrative rules and the federal Clean Water Act to obtain a permit and implement certain storm water control measures. After initially questioning its authority to fully implement these requirements and raising concerns about the absence of a funding source, the County declined to seek coverage under the 2022 general permit. However, after being ordered by the EPA to either cease discharges or apply for permit coverage, the County filed a declaratory judgment action seeking a categorical ruling that it lacked the legal authority to comply with the regulatory requirements and that those requirements constituted an unfunded mandate.The Thirteenth Judicial District Court, Yellowstone County, granted summary judgment to the Montana Department of Environmental Quality (DEQ), holding that the County had sufficient authority to implement the required storm water controls and that the permit requirements did not constitute an unfunded mandate. The court found that exceptions to the unfunded mandate statute applied, including constitutional, federal statute, and operational-necessity exceptions. The County appealed the decision, maintaining that it could not lawfully implement certain third-party regulatory mechanisms required by the rules.The Supreme Court of the State of Montana affirmed the District Court’s grant of summary judgment to DEQ, though on narrower grounds. The Supreme Court held that Yellowstone County is legally obligated to obtain permit coverage for its MS4 discharges and to implement required storm water controls using whatever powers Montana law expressly provides or necessarily implies. The Court clarified that DEQ cannot compel the County to exercise authority it does not possess, but the County's lack of comprehensive third-party regulatory power does not excuse it from the obligation to comply through lawful means. The Court also held that the requirements did not amount to an unfunded mandate because they originate from federal statutory obligations, which are excepted from Montana’s unfunded mandate statute.

The case concerns a challenge by an environmental organization to a U.S. Forest Service project in the Idaho Panhandle National Forest known as the Hanna Flats Good Neighbor Authority Project. The Project was intended to manage vegetation and reduce wildfire risk, and involved the use and closure of several miles of road within an area known as the Priest Bears Outside Recovery Zone (BORZ), which is important grizzly bear habitat. After the Project was approved, it was discovered that the total miles of road in the Priest BORZ exceeded the baseline established in 2011 by the Access Amendments to the Forest Plan, which limited road construction to protect bear habitat. This overage was due to roads that existed before 2011 but were not included in the original baseline survey.The United States District Court for the District of Idaho granted summary judgment in favor of the environmental group, finding that the Project violated the Access Amendments and, therefore, the National Forest Management Act (NFMA) because total road mileage after the Project would exceed the 2011 baseline. The district court did not analyze whether the Project itself caused or contributed to the noncompliance with the baseline.The United States Court of Appeals for the Ninth Circuit reviewed the case. It held that, under NFMA and circuit precedent, a site-specific project is consistent with a forest plan so long as the project does not itself cause or worsen noncompliance with the plan’s requirements. The court found that the excess road mileage was entirely attributable to preexisting roads not caused by the Project, and that the Project would actually reduce total road mileage. The court also rejected arguments that the Project violated temporary road requirements. Thus, the Ninth Circuit reversed the district court’s judgment and remanded for further proceedings.

Three adjacent residential parcels in Los Gatos were subject to a lot line adjustment application in 2023, submitted by the owners’ architect. One parcel had an existing house, while two were unimproved and nonconforming with zoning requirements. The adjustment sought to resolve nonconformities, including minimum lot size and street frontage. As a condition, the Town required an offer of dedication for a cul-de-sac easement to provide new access and satisfy frontage requirements. The Town accepted this dedication, resulting in a mapped cul-de-sac extension.The Town’s development review commission approved the adjustment, and subsequent appeals by an adjacent homeowner, Alison Steer, were denied by the planning commission and Town Council. Steer argued the approval was discretionary, not ministerial, due to the Town’s acceptance of the dedication, which she claimed triggered the need for environmental review under the California Environmental Quality Act (CEQA). The Town filed a notice of exemption, stating the approval was ministerial and thus exempt from CEQA. Steer then filed a petition for writ of mandate in the Santa Clara County Superior Court, alleging CEQA violations. The trial court denied the petition, reasoning that the dedication was for zoning compliance and the Town lacked discretion to refuse it, making the approval ministerial.The Court of Appeal of the State of California, Sixth Appellate District, reviewed the case. It held that while lot line adjustments are typically ministerial, this approval included a discretionary element—the Town’s acceptance of the property dedication for the cul-de-sac. The court found that the Town had discretion to accept, modify, or reject the dedication, which made the project discretionary for CEQA purposes. Accordingly, the court reversed the trial court’s judgment and remanded with instructions to grant the petition for writ of mandate, concluding the Town violated CEQA by relying on the ministerial exemption.

The case concerns several quarry operations in Chester, Vermont. Chandler Quarry, operated on an eight-and-a-half-acre parcel, had been exempt from Vermont’s Act 250 land use permitting requirements since its operations predated the Act’s passage in 1970. In 2018, a landowner acquired Chandler Quarry, as well as North and South Quarries located nearby. The landowner then began coordinating operations across all three quarries, including processing stone from North and South at Chandler Quarry and constructing a new building to house processing equipment. This expanded activity increased quarrying, noise, and traffic, resulting in complaints from neighboring landowners.Following these complaints, the District 2 Environmental Commission issued a jurisdictional opinion in 2023, determining that Chandler Quarry’s integration into the larger quarry operation constituted a substantial change, subjecting it to Act 250 permitting requirements. The landowner appealed to the Vermont Superior Court, Environmental Division, which, in March 2024, affirmed that Chandler Quarry’s coordinated operation with the other quarries triggered Act 250 jurisdiction. Afterward, the Land Use Review Board (LURB) issued an administrative order in June 2025, imposing a civil penalty and a stop-work order, requiring cessation of Chandler Quarry operations until appropriate permits were obtained. The landowner requested a merits hearing, during which it was shown that Chandler Quarry operations had been reduced to pre-2018 levels and decoupled from North and South Quarries.The Vermont Supreme Court reviewed the appeal. It held that Chandler Quarry remains subject to Act 250 jurisdiction, despite the reduction of operations, because the expanded, unpermitted commercial activity persisted for years and caused lasting environmental impacts. The Court distinguished this case from In re Audet, finding that the landowner’s sustained jurisdiction-triggering activities could not be undone simply by reverting to previous operational levels. The Court also held that the Environmental Division’s affirmation of the stop-work order was not an abuse of discretion, as the Division reasonably considered statutory factors, including economic effects on employees. The Supreme Court affirmed the Environmental Division’s decision. View "Land Use Review Board v. 3643 VT Route 103, N, LLC" on Justia Law

Several plaintiffs, who own downstream water rights on the Baker-Lehman Creeks in Nevada, alleged that activities by Great Basin National Park—including water diversion and vegetation planting—reduced water flow and threatened their ability to use water as determined by a 1934 Nevada state court decree. This decree (the Baker-Lehman Decree) set out the rights of all claimants to water from these creeks, which now originate and flow through federally managed land. The plaintiffs sought to enjoin the United States from activities that interfered with their water rights.The case began in Nevada state court, where plaintiffs filed to enforce their rights under the 1934 decree. The United States removed the case to the United States District Court for the District of Nevada and asserted sovereign immunity from suit. The district court found that sovereign immunity was not waived, reasoning that the McCarran Amendment did not apply because the United States did not participate in the original adjudication and thus the decree was not “comprehensive.” It dismissed the case for lack of subject matter jurisdiction.On appeal, the United States Court of Appeals for the Ninth Circuit reviewed the district court’s dismissal de novo. The appellate court held that the McCarran Amendment retroactively waives the United States’ sovereign immunity for suits seeking administration of water rights determined in a comprehensive state adjudication. The court found that the Baker-Lehman Adjudication was comprehensive under Nevada’s statutory system, regardless of the United States’ prior participation. The plaintiffs’ suit to enforce their adjudicated water rights constitutes administration under the McCarran Amendment. Accordingly, the Ninth Circuit reversed the district court’s dismissal and remanded the case, holding that the United States’ sovereign immunity was waived for this suit. View "BAKER RANCHES, INC. V.
