This set of regulations proposed today is known as the Stage 2 Disinfectants and Disinfection Byproducts Rule (Stage 2 DBPR). EPA's objective for the Stage 2 DBPR is to reduce the potential risks of reproductive and developmental health effects and cancer associated with disinfection byproducts (DBPs) by reducing peak and average levels of DBPs in drinking water supplies. The Stage 2 DBPR applies to public water systems (PWS) that are community water systems (CWSs) or nontransient noncommunity water systems (NTNCWs) that add a primary or residual disinfectant other than ultraviolet light or deliver water that has been treated with a primary or residual disinfectant other than ultraviolet light. 68 FR 49548 https://www.govinfo.gov/app/details/FR-2003-08-18/03-18149 03-18149 fr18au03-44 RIN 2040-AD38 6560-50-P FRL-7530-3 https://www.govinfo.gov/app/details/FR-2003-08-18/03-18149 https://www.govinfo.gov/content/pkg/FR-2003-08-18/html/03-18149.htm https://www.govinfo.gov/content/pkg/FR-2003-08-18/pdf/03-18149.pdf Chemicals Indians-Lands Intergovernmental Relations Radiation Protection Reporting and Recordkeeping Requirements Water Supply Administrative Practice and Procedure 134 p. 49548 49681 68 FR 49548 Title 40 Part 141 40 CFR Part 141 Title 40 Part 142 40 CFR Part 142 Title 40 Part 143 40 CFR Part 143 RIN 2040-AD38 National Primary Drinking Water Regulations: Stage 2 Disinfectants and Disinfection Byproducts Rule; National Primary and Secondary Drinking Water Regulations: Approval of Analytical Methods for Chemical Contaminants; Federal Register Vol. 68, Issue PRORULE 03-18149 II ENVIRONMENTAL PROTECTION AGENCY 2003-11-17 FRL-7530-3 6560-50-P 03-18149 Proposed rule.
