In keeping with the MassDEP Regulatory Reform Initiative, at 310 CMR 40.0000, the LSP Board seeks to align its goals with those of the Massachusetts Contingency Plan by administering an examination that tests the latest technological advances in the complex field of coordinating and implementing responses to hazardous waste site cleanup.  This notice is therefore provided to inform applicants that a new licensing examination is in development.  The new iteration of the exam will provide a meaningful metric allowing the Board to track data and make quantifiable comparisons.  the Board will offer the new examination in or before spring 2015.  Please contact the LSP Board at lsp.board@state.ma us for further information.

Those private parties who are financially responsible under Massachusetts law for assessing and cleaning up confirmed and suspected hazardous waste sites must retain a licensed Hazardous Waste Site Cleanup Professional (commonly called a "Licensed Site Professional" or simply an "LSP") to oversee the assessment and cleanup work. The Board of Registration of Hazardous Waste Site Cleanup Professionals is an independent, 11-member board that licenses and regulates LSPs. The Board works to maintain high standards of practice and to protect public health, welfare, and the environment by establishing qualifications for licensure, administering a licensing exam, requiring that LSPs obtain continuing education, and investigating complaints against LSPs to ensure compliance with state laws, regulations and the Board's own rules of professional conduct.
