EPA Analysis: On November 19, 2009, the Commonwealth of Kentucky submitted requests that the Region approve revisions to the Commonwealth’s Safe Drinking Water Act Public Water System Supervision Program to include the authority to implement and enforce the Consumer Confidence Report Rule and the Long
Term 1 Enhanced Surface Water Treatment Rule. On October 14, 2010, the Commonwealth of Kentucky also submitted a request that the Region approve revisions to the Commonwealth’s Safe Drinking Water Act Public Water System Supervision Program to include the authority to implement and enforce the Ground
Water rule. For the revisions to be approved, the EPA must find the State Rules, 401 KAR 8:075, Section 1(1); 401 KAR 8:150, Section 8; and 401 KAR 8:150, Section 10 to be no less stringent
than the Federal Rules codified at 40 CFR part 141, Subpart O—Consumer Confidence Reports; 40 CFR part 141, Subpart T—Enhanced Filtration and Disinfection—Systems Serving Fewer Than 10,000 People; and 40 CFR part 141, Subpart S—Ground Water Rule. The EPA reviewed the applications using the Federal statutory provisions (Section 1413 of the Safe Drinking Water Act), Federal regulations (at 40 CFR part 142), State regulations, rule crosswalks, and EPA regulatory guidance to determine whether the request for revisions is approvable. The EPA determined that the Kentucky
