Contract Laboratory Program (CLP) (CLP)

The Environmental Protection Agency (EPA)'s Contract Laboratory Program (CLP) is a national network of EPA personnel, commercial laboratories, and support contractors whose fundamental mission is to provide data of known and documented quality. The CLP supports the EPA's Superfund effort originally under the 1980 Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and under the 1986 Superfund Amendments and Reauthorization Act (SARA).
