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.

In March 2024, the County of Bucks filed a controversial suit under state law against a number of large oil companies alleging the County was injured because of the companies’ deceptive conduct with respect to their impact on climate change. The Defendants filed various preliminary objections including lack of subject-matter jurisdiction, arguing that despite the County’s effort to focus the complaint on fraudulent practices, the case at bottom alleged harm from severe weather allegedly due to air emissions, which are governed exclusively by federal law. On May 16, 2025, the Bucks County Court of Common Pleas issued an opinion agreeing with the Defendants and dismissing the case entirely.  See Bucks County v. BP P.L.C., et al., No. 2024-01836 (Bucks Cty. Com. Pl. May 16, 2025). 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 recent case from the United States District Court for the Western District of Pennsylvania, the court granted a partial motion to dismiss the plaintiff’s common law claims because they were deemed time-barred under Pennsylvania law.  Iorfido v. Domtar Paper Company, LLC et al., No. 23-156, 2024 WL 1346641 (W.D. Pa. Mar. 29, 2024).  The lawsuit stemmed from a paper mill’s ongoing emissions of lime particulate matter that allegedly harmed plaintiff’s property.  The court dismissed the common law claims as obviously barred by the two-year statute of limitations as pled in plaintiff’s complaint.

On November 1st, 2023, in a split 4-1 opinion with a dissent, the Pennsylvania Commonwealth Court held that Pennsylvania cannot participate in the Regional Greenhouse Gas Initiative (“RGGI”) because the regulations intended to implement RGGI pursuant to the Air Pollution Control Act (“APCA”) constitute an impermissible tax rather than a fee. Bowfin KeyCon Holdings, LLC vs. Pa. Dep’t of Env’t Prot. and Pa. Env’t Quality Bd., 2023 WL 7171547, at *1 (Pa. Commw. Ct. Nov. 1, 2023). The holding halts former Governor Tom Wolf’s efforts to make Pennsylvania the first major fossil-fuel producing state to implement a price on carbon emissions.     Read More »

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 a case which will have major implications throughout Pennsylvania, on January 4, 2023, the Pennsylvania Commonwealth Court ruled that the school system defendants, which are immune from taxation, were not required to pay the Borough of West Chester’s stormwater charge because “the Stormwater Charge constitutes a local tax”.  Borough of West Chester v. Pa. State System of Higher Education and West Chester University of Pa. of the State System of Higher Education, No. 260 M.D. 2018 (Pa. Cmwlth. Jan. 4, 2023).  The Court held that the stormwater charge constituted a tax and not a fee or special assessment because the charge provided benefits enjoyed by the general public, rather than individualized services provided to particular customers.  Read More »

In an opinion issued last month, the Third Circuit affirmed the dismissal of a lawsuit brought by the Adorers of the Blood of Christ, an order of Roman Catholic nuns, against the Transcontinental Gas Pipe Line Company (“Transco”) under the Religious Freedom and Restoration Act (“RFRA”).  Adorers of the Blood of Christ U.S. Province v. Transcontinental Gas Pipe Line Co LLC, 53 F.4th 56 (3d Cir. 2022).  The Adorers’ sought in their lawsuit money damages from Transco as a result of the completed construction of a pipeline across the Adorers’ property, which they argued amounted to a substantial burden on their exercise of religion under RFRA.  The Third Circuit upheld the dismissal of the suit, holding that the Adorers’ lawsuit was “inescapably intertwined” with an earlier approval issued for the pipeline by the Federal Energy Regulatory Commission (“FERC”) and therefore amounted to an impermissible collateral attack on that approval that was precluded by the Natural Gas Act.  Read More »

A successful defense of a mass environmental tort case frequently turns on class certification.  In Holly Lloyd v. Covanta Plymouth Renewable Energy, LLC, No. 20-4330, 2022 WL 407377 (E.D. Pa. Feb. 10, 2022), a federal district court denied a motion to certify a class of neighboring residents complaining about noxious odors from a municipal waste incinerator.  In so holding, the court’s decision set out key strategies and considerations for defeating class certification in future mass environmental tort cases.  Read More »
