Start Preamble


Environmental Protection Agency (EPA).


Notice of tentative approval.


Notice is hereby given that the State of Wisconsin is revising its approved Public Water System Supervision Program. Wisconsin has adopted the Arsenic Rule for all community and nontransient, noncommunity water systems which, among other things, changes the arsenic maximum contaminant level from 0.050 mg/L to 0.010 mg/L to improve public health by reducing exposure to arsenic in drinking water.

EPA has determined that these revisions are no less stringent than the corresponding federal regulations. Therefore, EPA intends to approve these program revisions. This approval action does not extend to public water systems (PWSs) 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.

However, if a substantial request for a public hearing is made by August 20, 2007, a public hearing will be held.
