Notwithstanding any other general or special law to the contrary Section 7 of Chapter 21A of the General Laws, as appearing in the 2020 Official Edition, is hereby amended by inserting at the end there of the following: -

Section 7: (a) For purposes of this section following actions shall be taken by the Department of Environmental Protection:

The Department of Environmental Protection  shall review the Guidelines on chemicals found in drinking water tested in the Commonwealth for the purposes of classifying Massachusetts maximum containment levels for certain harmful compounds. The Department of Environmental protection shall, with respect to n-Nitrosodimethylamine, promulgate Massachusetts maximum containment levels, that shall be considered the maximum safe amount of n-Nitrosodimethylamine present in drinking water so that it does not negatively affect human health.

The Department of Environmental Protection shall, upon receiving reports of levels of n-Nitrosodimethylamine outside the Massachusetts maximum containment levels, provide a copy of those reports to the Clerks of the House and the Senate. The Department of Environmental Protection shall then treat any such level found above the Massachusetts maximum containment level as if it were a violation of the Department of Environmental Protection Drinking Water regulation 310 CMR 22.00.  Pursuant to 310 CMR 22.01(2) the Department of Environmental Protection shall exercise its authority as it sees fit to enforce the standard of the Massachusetts maximum containment levels promulgated in this section with respect to n-Nitrosodimethylamine.

The Department of Environmental Protection shall provide a report annually to the clerks of the House and the Senate that details the total number of examinations done of drinking water in the Commonwealth, as well as how many of those were found to contain n-Nitrosodimethylamine levels above the Massachusetts maximum containment level.
