          - [FRL 8718-01-R5]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of tentative approval.

# SUMMARY:

Notice is hereby given that the Environmental Protection Agency (EPA) has tentatively approved the State of Wisconsin's revisions to the State's Public Water System Supervision (PWSS) Program under the federal Safe Drinking Water Act (SDWA) for adoption of the federal Ground Water Rule, as well as revisions to the federal Surface Water Treatment Rule under the Long Term 2 Enhanced Surface Water Treatment Rule. The EPA has determined that the State's PWSS program regulations and the revisions thereto are no less stringent than the corresponding federal regulations for the Ground Water Rule and the Long Term 2 Enhanced Surface Water Treatment Rule. Therefore, the EPA intends to approve this revision to the State of Wisconsin's Public Water System Supervision Program, thereby giving the Wisconsin Department of Natural Resources primary enforcement responsibility for the Ground Water Rule and the Long Term 2 Enhanced Surface Water Treatment Rule. This approval action does not extend to public water systems in Indian Country. By approving this revision, the 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.
