Case Brief Summary & Legal Analysis

General Brief
4 min read

tl;dr: A current landowner sued a prior owner for cleanup costs under CERCLA. The court held that the gradual, passive migration of contaminants through soil during the prior owner’s tenure did not constitute a “disposal,” thereby absolving the prior owner of liability as a potentially responsible party.

Legal Significance: This case established the Ninth Circuit’s influential interpretation of “disposal” under CERCLA, holding that the term does not include passive soil migration. This holding narrows the scope of liability for past landowners who did not actively contaminate the property.

Case Facts & Court Holding

Key Facts & Case Background

Carson Harbor Village, Ltd. (“Carson Harbor”) purchased a 70-acre mobile home park in 1983 from the Partnership Defendants, who had owned it since 1977. Prior to and during the Partnership’s ownership, Unocal Corporation operated petroleum production facilities on the site, leaving behind tar-like and slag materials. In 1993, while attempting to refinance, Carson Harbor discovered that these materials, containing lead and total petroleum hydrocarbons (TPH), had contaminated a 17-acre wetlands area on the property. Evidence suggested the contaminants were passively migrating through the soil. Acting under the oversight of the Regional Water Quality Control Board, Carson Harbor excavated the materials and contaminated soil at a cost of approximately $285,000. Carson Harbor then sued the Partnership Defendants under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to recover these costs, arguing they were liable as owners “at the time of disposal.” The Partnership Defendants contended that no “disposal” occurred during their ownership because the contamination was pre-existing and its subsequent movement was merely passive migration.

Court Holding & Legal Precedent

Issue: Does the gradual, passive migration of pre-existing hazardous substances through soil constitute a “disposal” under CERCLA § 107(a)(2), thereby making a past, non-polluting landowner a potentially responsible party?

No. The court held that the passive migration of contaminants through soil Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
