We assist clients in recovering costs, and defending against claims seeking costs, under the Massachusetts Superfund Law, G.L. c. 21E. That statute, together with MassDEP’s regulations (called the MCP), establishes responsibility and imposes liability for releases of hazardous materials, oil and other petroleum products. We represent all types of potentially responsible parties, including owners, operators or others who generated, stored, transported, or disposed of oil or hazardous materials.
