# ACTION:

Notice. 

# SUMMARY:

The State of South Dakota has revised its Public Water System Supervision (PWSS) primacy program by adopting regulations for the Consumer Confidence Report Rule that correspond to 40 CFR part 141, Subpart O. Having determined that these revisions meet all pertinent requirements in the Safe Drinking Water Act, 42 U.S.C. 300f et seq., and EPA's implementing regulations at 40 CFR parts 141 and 142, the EPA approves them. 

                        Today's approval action does not extend to public water systems in Indian Country as that term is defined in 18 U.S.C. 1151. Please see                         **SUPPLEMENTARY INFORMATION**                        , Item B.

# SUPPLEMENTARY INFORMATION:

Effective January 9, 1984, EPA approved South Dakota's application for assuming primary enforcement authority for the PWSS program, pursuant to section 1413 of the Safe Drinking Water Act (SDWA), 42 U.S.C. 300g-2, and 40 CFR part 142 (see 48 FR 55173.) The South Dakota Department of Environment and Natural Resources (DENR) administers South Dakota's PWSS program. 

## A. Why are Revisions to State Programs Necessary? 

States with primary PWSS enforcement authority must comply with the requirements of 40 CFR part 142 for maintaining primacy. They must adopt regulations that are at least as stringent as the National Primary Drinking Water Regulations (NPDWRs) at 40 CFR part 141. (40 CFR 142.10(a).) Changes to state programs may be necessary as federal primacy requirements change, as states must adopt all new and revised NPDWRs in order to retain primacy. (40 CFR 142.12(a).) 

## B. How Does Today's Action Affect Indian Country (18 U.S.C. 1151) in South Dakota? 

South Dakota is not authorized to carry out its Public Water System Supervision program in Indian country, as defined in 18 U.S.C. 1151. This includes, but is not limited to: Lands within the exterior boundaries of the following Indian Reservations located within the State of South Dakota:

a. Cheyenne River Indian Reservation. 

b. Crow Creek Indian Reservation. 

c. Flandreau Indian Reservation. 

d. Lower Brule Indian Reservation. 

e. Pine Ridge Indian Reservation. 

f. Rosebud Indian Reservation. 

g. Standing Rock Indian Reservation. 

h. Yankton Indian Reservation. 

                    EPA held a public hearing on December 2, 1999, in Badlands National Park, South Dakota, and accepted public comments on the question of the location and extent of Indian country within the State of South Dakota. In a forthcoming                     **Federal Register**                     notice, EPA will respond to comments and more specifically identify Indian                           ( print page 69775)                        country areas in the State of South Dakota.
