The Massachusetts Department of Environmental Protection (MassDEP) implements the state’s waste site cleanup program (the 21E program) through a set of regulations known as the Massachusetts Contingency Plan (MCP). The MCP details the framework under which contaminated sites are cleaned up and requires the use of state Licensed Site Professionals known as LSPs. LSPs are hired by people responsible for the cleanup to manage and oversee the assessment and remediation of the site.
LSPs are licensed by the Board of Registration of Hazardous Waste Site Cleanup Professionals. The board reviews LSP applicants based on strict education and work history requirements. Upon approval, LSPs must pass an examination that tests their technical and regulatory knowledge.
