CERCLA Liability For Mining and Milling Operations

The Act also provides a method of funding response actions and imposes ultimate liability on persons responsible for creating the problems caused by the disposal and release of hazardous substances.

At the time of the enactment of CERCLA, the mining and milling industry believed it was temporarily exempted from the statute in the same fashion it had been temporarily exempted from subtitle C of the Solid Waste Disposal Act, as amended by the Resource Conservation and Recovery Act (RCRA).2 When, however, the United States Environmental Protection Agency (EPA) published the first proposed National Priorities List, identifying sites for response actions under CERCLA, several mining and milling sites were included.3 In addition, EPA has sought to enforce the provisions of CERCLA
