The Department is adopting the national Stage 2 Disinfectants and Disinfection Byproducts Rule (D/DBPR) with related State clarifications and additions, and the Department is updating the State’s public water system recordkeeping and Stage 1 D/DBPR requirements to incorporate changes that were made to the record maintenance and Stage 1 D/DBPR requirements in the national primary drinking water regulations and that were promulgated with the Stage 2 D/DBPR. Also, the Department is updating the State’s listing of analytical methods for primary or secondary contaminants and the State’s consumer confidence report (CCR) requirements so they are consistent with current national primary or secondary drinking water regulations.
