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 »
