# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of tentative approval.

# SUMMARY:

Notice is hereby given that the State of Washington has revised its approved State Public Water Supply Supervision Primacy Program. Washington has adopted a definition for public water system that is analogous to EPA's definition of public water system, and has adopted regulations analogous to EPA's Consumer Confidence Report Rule, Interim Enhanced Surface Water Treatment Rule, Stage 1 Disinfectants and Disinfection Byproducts Rule, Lead and Copper Minor Revisions Rule, Public Notification Rule, Radionuclides Rule, Arsenic Rule, Filter Backwash Rule, Long Term 1 Enhanced Surface Water Treatment Rule, Variance and Exemptions Rule, Stage 2 Disinfectants and Disinfection Byproducts Rule, Long Term 2 Enhanced Surface Water Treatment Rule, and Ground Water Rule. EPA has determined that these revisions are no less stringent than the corresponding Federal regulations. Therefore, EPA intends to approve these State program revisions. By approving these rules, EPA does not intend to affect the rights of Federally recognized Indian Tribes within “Indian country” as defined by 18 U.S.C. 1151, nor does it intend to limit existing rights of the State of Washington.
