On January 3, 2024, the United States Court of Appeals for the Tenth Circuit reversed a district court decision that held that a Colorado gold mining company’s operation of four settling ponds constituted an unpermitted discharge of pollutants into navigable waters under the Clean Water Act (“CWA”).  In Stone v. High Mountain Mining Company, No. 22-1340 (10th Cir. 2024), the Tenth Circuit held that the district court did not correctly follow the Supreme Court’s decision in County of Maui v. Hawaii, 140 S. Ct. 1462 (2020) regarding the CWA’s applicability to indirect discharges to navigable waters. 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.

On June 25, 2021, the Supreme Court, reversing the Tenth Circuit, held that a small refinery that had previously received an exemption from certain requirements of the renewable fuel standard (“RFS”) program was eligible for an extension of that exemption, even if it had had a lapse in coverage in previous years. See HollyFrontier Cheyenne Refining, LLC, v. Renewable Fuels Association, et al., Slip Op. 20-472 (June 25, 2021). Petitioners, three small fuel refineries, had each applied for a hardship exemption under the RFS program, and the Environmental Protection Agency (“EPA”) had granted each request. Those exemptions were then challenged by a group of renewable fuel producers. The Tenth Circuit ultimately sided with the renewable fuel producers, holding that because each refinery had allowed its previously held exemption to lapse at times in the past, each was no longer eligible to receive an extension of the original exemption. After hearing oral argument in April 2021, the Supreme Court reversed the Tenth Circuit and held that the text of the statute does not require that the exemption be continually held in order to remain valid.

On July 19, 2017, the Tenth Circuit Court of Appeals held that the United States, as the title owner of a former mine, was a Potentially Responsible Party (PRP) under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), despite the fact that it did not have a possessory interest in the property at the time of the disposal of hazardous substances.  The opinion in Chevron Mining Inc. v. United States, No. 15-2209, 2017 U.S. App. LEXIS 12959, at *1 (10th Cir. July 19, 2017) thus appears to put to rest a defense often asserted, primarily by governmental entities, that “bare legal title” is insufficient for CERCLA liability to attach and instead that some other and additional “indicia of ownership” is required.

Last week, the United States Court of Appeals for the Tenth Circuit ruled that a PRP’s bankruptcy settlement of its CERCLA liability did not bar that PRP from later seeking contribution for a share of the settlement – despite the bankruptcy court’s determination that the settlement represented the PRP’s “fair share” of CERCLA liability.  Read More »

Last week, the 10th Circuit Court of Appeals affirmed dismissal of a Sierra Club citizen suit against a coal-fired power plant for an alleged permitting violation of the Clean Air Act, finding that the Sierra Club’s claims were time-barred.  In the case, Sierra Club v. Okla. Gas & Elec. Co., No. 14-7065 (10^th Cir. March 8, 2016), the court held that the Sierra Club’s claims for civil penalties were statutorily time-barred because they were brought more than five years after the power plant began its unpermitted modification of a boiler, an action which the Sierra Club claims violated the Prevention of Significant Deterioration (PSD) program under the Clean Air Act.  The court also affirmed dismissal of the group’s claims for injunctive and declaratory relief because those legal claims were predicated on the same facts as the time-barred civil penalties.  The court’s interpretation of the statute of limitations as applied to the PSD program is consistent with a 2011 district court decision in the 3rd Circuit, United States v. EME Homer City Generation L.P., et al., which we reported on here. Read More »

One of the very first things I was told by the senior partner when I started practicing law was that there isn’t an honest mistake that can’t be fixed, except blowing the statute of limitations. As a result, my calendar has limitations periods blocked out weeks, months and in some cases years in advance, and if there’s ever a question of when it runs, I use the earliest date. The Tenth Circuit’s decision in Impact Energy Resources, LLC v. Salazar, Nos. 11-4043 & 11-4057 (Sept. 5, 2012 10^th Cir.), is a cautionary tale to those who may not be as conservative. Read More »
