309 CMR, § 4.01
In order to safeguard the public health, safety, welfare and the environment and to establish and maintain a standard of professional integrity, the Board has established 309 CMR 4.00 (Rules of Professional Conduct). 309 CMR 4.00 shall be binding on every person licensed by the Board to render waste site cleanup activity opinions within the meaning of M.G.L. c. 21A, § 19.
Any person who may become aware of the failure of a licensed site professional to comply with an obligation or prohibition imposed by 309 CMR 4.00 may file a complaint with the Board pursuant to 309 CMR 7.00. However, the availability of this right is not intended to subject an LSP to any liability in addition to any actions that may be taken by the Board, nor is it intended that a violation of 309 CMR 4.00 shall by itself give rise to a private cause of action or create any presumption that a legal duty to a party other than the Board or the Department has been breached.
All LSPs are charged with having knowledge of 309 CMR 4.00 and shall be deemed to be familiar with the provisions and to understand them.
