Chevron Mining v. United States, No. 15-2209 (10th Cir. 2017)Annotate this Case
Under the federal environmental laws, the owner of property contaminated with hazardous substances or a person who arranges for the disposal of hazardous substances may be strictly liable for subsequent clean-up costs. The United States owned national forest lands in New Mexico that were mined over several generations by Chevron Mining Inc. The question presented for the Tenth Circuit’s review was whether the United States is a “potentially responsible party” (PRP) for the environmental contamination located on that land. The Tenth Circuit concluded that under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), the United States is an “owner,” and, therefore, a PRP, because it was strictly liable for its equitable portion of the costs necessary to remediate the contamination arising from mining activity on federal land. The Court also concluded the United States cannot be held liable as an “arranger” of hazardous substance disposal because it did not own or possess the substances in question. The Court reversed the district court in part and affirmed in part, remanding for further proceedings to determine the United States’ equitable share, if any, of the clean-up costs.
