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 .

NA - Not Applicable

* - The Total Chromium standard is applicable in the absence of species-specific data for Chromium III and Chromium VI.

** - Cyanide expressed as Physiologically Available Cyanide (PAC). In the absence of measured Physiologically Available Cyanide, the standard is applicable to Total Cyanide.

+ - The Total Petroleum Hydrocarbon (TPH) standard may be used as an alternative to the appropriate combinations of the Aliphatic and Aromatic Hydrocarbon Fraction standards. The use of the general TPH standard is a valid option only for C9 and greater petroleum hydrocarbons; it is not appropriate for the characterization of risks associated with lighter (gasoline-range) hydrocarbons.

++ - The Department periodically reviews the scientific basis for these Standards and amends them, as appropriate, to incorporate new scientific information.
