    This copy of the Massachusetts Contingency Plan, 310 CMR 40, is not an "Official Version" of the regulations. In particular, it lacks page numbers and the effective dates at the bottom of each page. Other unexpected differences may also be present. This HTML version is offered as a convenience to our users and DEP believes that the body of the text is a faithful copy of the regulations. If you REALLY, ABSOLUTELY, MUST know that the version you have is correct and up-to-date, then you must purchase the document through the State Bookstore. The official versions of all state statutes and regulations are only available through the  Massachusetts State Bookstore .
