Peterborough Oil Co., LLC v. Dep’t of Envtl. Prot.

By
Department of Environmental Protection (DEP) regulations require that those deemed to be liable after a spill of hazardous materials within a specified radius of a public water supply undertake cleanup and monitoring to ensure the spill does not pose a danger to that water supply, 310 Code Mass. Regs. 40.0801, 40.0810, 40.0993(3)(a), 40.1030(2)(e). A 2007 modification exempts "oil" from some requirements when specific conditions are met, 310 Code Mass. Regs. 40.0924(2)(b)(3)(a). Peterborough owns a now-vacant Athol property, within a protection area, where it operated a gasoline station for more than 10 years. In 1994, a release of leaded gasoline from a subterranean gasoline storage tank was detected in soil on the site. DEP required Peterborough to undertake supervised cleanup and monitoring activities. In 2008, after the oil exemption was established, Peterborough submitted a revised plan, stating that further remediation was not required because the entirety of the spill fell within the exemption's definition of "oil." DEP responded that the meaning of "oil" in the exemption does not include gasoline additives such as lead, but refers only to petroleum hydrocarbons naturally occurring in oils, so that a spill of leaded gasoline could not be completely excluded from further remediation. The trial court, on summary judgment, and the Massachusetts Supreme Judicial Court, upheld the DEP interpretation of the regulation as reasonable. View "Peterborough Oil Co., LLC v. Dep't of Envtl.
