Upon written request from an individual licensed by the board as a hazardous waste site cleanup professional, the board may render an advisory opinion interpreting one or more regulations promulgated by the board establishing standards for professional conduct. An opinion rendered by the board, until and unless amended or revoked, shall be a defense in a criminal action brought under sections nineteen through nineteen J, inclusive, and shall be binding on the board in any subsequent proceedings concerning the individual who requested the opinion and acted in good faith in reliance thereon, unless material facts were omitted or misstated by the individual in the request for an opinion. Such requests shall be confidential; provided, however, that the board may publish such opinions, but the name of the requesting individual and other identifying information shall not be included in such publication unless the requesting individual consents to such inclusion.
Notwithstanding any other general or special law to the contrary, no licensed hazardous waste site cleanup professional shall be liable to any other person for making any disclosure in good faith if such disclosure is required pursuant to any law or to any regulation or order of the board or of the department or of any agency of the United States, or of the commonwealth, or of any city or town or other body politic, or pursuant to any court order or judicial process.
