A recent decision from the United States District Court for the Middle District of Pennsylvania offers insight into cost recovery claims under both the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) and Pennsylvania's Hazardous Sites Cleanup Act (“HSCA”).  On March 6, 2026, in Blettner Avenue, LLC v. Central Uniform Services, Inc., the Middle District denied Defendants Rental Uniform Services, Inc. (“Rental Uniform Services”) and Cintas Corporation (“Cintas”)’s motion for summary judgment as to Plaintiff Blettner Avenue, LLC (“Blettner”)’s HSCA claim, shedding light on HSCA’s time limitation provision and the scope of “response costs” under the statute.  On the other hand, the Court granted Defendants’ motion for summary judgment as to Blettner’s CERCLA claim, finding Blettner failed to comply with National Contingency Plan (“NCP”) requirements.  The decision provides useful insight for practitioners to consider regarding statute of limitation under HSCA, the scope of “response costs” under HSCA and CERCLA, and NCP compliance under CERCLA.

A federal district court in Massachusetts recently issued companion decisions addressing the “useful product defense” in the context of biosolids that contain per- and polyfluoroalkyl substances (PFAS).  In twin orders dated December 30, 2025, the court held that biosolid pellets, or “biopellets”—which are produced from treated wastewater solids and used as fertilizer—are “useful products,” providing a defense to liability under Massachusetts’s analogue to the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

In a reversal of a decision by the New Jersey District Court, the Court of Appeals for the Third Circuit in In re Congoleum Corporation held 2-1 that the bankruptcy court did not have jurisdiction to reopen an earlier proceeding to interpret findings within a confirmation order, holding interpretation of such orders constitutes a bankruptcy core proceeding.  Chief Judge Chagares also reversed the district court as to the effect of that confirmation order in CERCLA proceedings currently pending before the district court.

Sept. 3, 2025) that CERCLA permits recovery of natural resource damages with a cultural use component, effectively reversing the district court’s holding that cultural resource damages are not authorized under CERCLA.

A recent decision sheds light on the U.S. government’s cleanup obligations in land sales involving former military sites.  In Hamilton Square, LLC v. United States, No. 20-1285 (Fed. Cl. July 15, 2025), the U.S. Court of Federal Claims allowed a key environmental remediation claim to proceed while dismissing others in a suit alleging the Navy breached its obligation to remediate newly discovered petroleum and chloroform contamination at a property in Novato, California.

On July 17, 2025, the Second Circuit issued an opinion in ELG Utica Alloys, Inc. v. Niagara Mohawk Power Corp. affirming an order granting summary judgment against ELG Utica Alloys, Inc.’s (“ELG”) in its CERCLA cost recovery suit, on the grounds that the applicable six-year statute of limitations had expired.  The decision is significant because it establishes a rule in the Second Circuit that, for a multi-phase remediation involving a single source of contamination at a single “facility,” the statute of limitations begins to run at the initiation of the first phase of cleanup.

Last month in Atlantic Richfield Company v. NL Industries, the Tenth Circuit Court of Appeals held that plaintiff Atlantic Richfield’s action under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) was timely, reversing the District Court’s determination applying the statute of limitations for cost recovery actions and granting summary judgment to the defendant NL Industries entities on that basis.

In joint tortfeasor settlements in private party actions under the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”), courts can choose from two competing federal contribution protection methods: the Uniform Comparative Fault Act (“UCFA”), known as pro rata, and the Uniform Contribution Among Tortfeasors Act (“UCATA”), known as pro tanto.  Last month, in City of Las Cruces and Dona Ana County v The Lofts of Alameda, LLC, Civil Action No. 2:17-cv-00809-JCH-GBW, 2024 WL 4512434, the U.S. District Court for the District of New Mexico considered the merits of both contribution protection methods and concluded that the pro rata approach was the most equitable under the circumstances.  Read More »

In Barclay Lofts LLC v. PPG Industries, Inc., Case No. 20-CV-1694, 2024 WL 4224731 (E.D. Wis. Sept. 18, 2024), a United States District Court in Wisconsin, after deciding several threshold issues under CERCLA, allocated liability for past and future response costs to clean up a contaminated site based upon a detailed analysis of the operational and material handling practices of the potentially responsible parties.  The decision offers insights about the facts that a court may find compelling and the factors that a court may apply to reach an equitable CERCLA allocation among responsible parties.

On September 27, 2024, in Short Creek Development, LLC v. MFA Incorporated, No. 22-05021-CV-SW-WBG, 2024 WL 4326815 (W.D. Mo. Sept. 27, 2024), Magistrate Judge W. Brian Gaddy determined Plaintiffs’ claim under Section 107(a) of the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”) was barred by the applicable statute of limitations as “physical on-site construction of the remedial action” occurred more than six years prior to when Plaintiffs brought their lawsuit.  Specifically, the Magistrate Judge found that costs related to a leachate collection system constructed approximately a year before the adoption of a Record of Decision (“ROD”) amendment outlining a permanent remedy for the Orongo-Duenweg Mining Belt Superfund Site (the “Site”) was the beginning of the six-year limitations period.   In doing so, the Court rejected adoption of a “bright-line” rule that remedial actions begun before adoption of a final remedial plan do not trigger the limitations period.  Read More »
