In Daikin Applied Americas, Inc. v. EPA, the D.C. Circuit Court of Appeals sided with the U.S. Environmental Protection Agency (“EPA”) by holding that a groundwater plume can be listed as a Superfund Site on the National Priorities List (“NPL”) pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”), 42 U.S.C. § 9601 et seq., even if the sources of contamination are not clearly identified. No. 20-1479, 2022 WL 2565083 (D.C. Cir. July 8, 2022). The Court also held that substantial evidence exists to support aquifer interconnectivity so long as observed releases occur at each aquifer. Thus, EPA’s decision to list a “groundwater plume with no identified source” that spanned multiple aquifers in an area southwest of Minneapolis, Minnesota on the NPL survived both arbitrary and capricious and substantial evidence challenges.

The First Circuit recently affirmed the District of Rhode Island’s approval of a superfund consent decree entered into between the United States Environmental Protection Agency (“EPA”), the State of Rhode Island and several Potentially Responsible Parties despite opposition by third party PRPs that the settlement was arbitrary and capricious and contrary to the Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA”). Emhart Indus., Inc. v. CNA Holdings LLC, No. 19-1563, slip op. (1st Cir. 2021 Feb. 17, 2021). What makes this case unique, and bolstered the arguments of the objectors, is that the settlement incorporated work pursuant to a ROD that the District Court had already determined has not been selected in accordance with law. Nevertheless, both the District Court and the First Circuit held that the finding did not preclude the settlement, leaving the objectors exposed to contribution claims for a remedy potentially inconsistent with the National Contingency Plan (“NCP”). In affirming the lower court, the First Circuit highlighted the “integral part” that early settlement plays in CERCLA’s statutory scheme, thus giving deference to the settling parties. Read More »
The D.C. Circuit recently held that EPA was not required to consider mitigation measures taken at a site when determining whether to add the site to the National Priorities List (“NPL”) under CERCLA. Meritor, Inc. v. EPA, No. 18-1325, 2020 WL 4299124 (D.C. Cir. July 28, 2020).
In 2016, the U.S. Environmental Protection Agency (“EPA”) conducted a study of indoor air quality at the Rockwell International Wheel & Trim facility (the “Site”), located in Mississippi, and discovered elevated concentrations of toluene, trichloroethylene (“TCE”), and cis-1,2-dichloroethene (“DCE”) in the main building at the Site. In 2017, Meritor, Inc. (“Meritor”), which inherited liability for contamination at the Site, conducted a subsurface investigation beneath the main building and uncovered elevated levels of toluene and TCE. In that same year, Meritor installed a sub-slab depressurization system designed to mitigate the impacts of vapor intrusion in the main building. In 2018, notwithstanding Meritor’s mitigation efforts, EPA added the Site to the NPL based on vapor intrusion impacts. Read More »
