The state of Wisconsin is revising its approved Public Water System Supervision Program. Wisconsin has revised its Public Notification (PN) Rule, its Lead and Copper Rule Minor Revisions (LCRMR) Rule and Radionuclides Rule.
EPA has determined that these revisions are no less stringent than the corresponding federal regulations. Therefore, EPA intends to approve these revisions to the State of Wisconsin's Public Water System Supervision Program. This approval action does not extend to public water systems in Indian Country, as that term is defined in 18 U.S.C. 1151. By approving these rules, EPA does not intend to affect the rights of federally recognized Indian tribes in Wisconsin, nor does it intend to limit existing rights of the state of Wisconsin.
