ACTION:

Notice.

SUMMARY:

The EPA has reviewed Montana's regulations and determined they are no less stringent than the federal regulations. The EPA is proposing to approve Montana's primacy revision for the RTCR.

This approval action does not extend to public water systems in Indian country. Please see Supplementary Information, Item B.

If a public hearing is requested and granted, then this determination shall not become applicable until such time following the hearing as the RA issues an order affirming or rescinding this action.

SUPPLEMENTARY INFORMATION:

In accordance with the provisions of section 1413 of the Safe Drinking Water Act (SDWA), 42 U.S.C. 300g-2, and 40 CFR 142.13, public notice is hereby given that the state of Montana has revised its PWSS program by adopting federal regulations for the RTCR that correspond to the NPDWR in 40 CFR parts 141 and 142. The EPA has reviewed Montana's regulations and determined they are no less stringent than the federal regulations. The EPA is proposing to approve Montana's primacy revision for the RTCR.

This approval action does not extend to public water systems in Indian country as defined in 18 U.S.C. 1151. Please see SUPPLEMENTARY INFORMATION, Item B.

A. Why are revisions to State programs necessary?

States with primary PWSS enforcement authority must comply with the requirements of 40 CFR part 142 to maintain primacy. They must adopt regulations that are at least as stringent as the NPDWRs at 40 CFR parts 141 and 142, as well as adopt all new and revised NPDWRs in order to retain primacy (40 CFR 142.12(a)).

B. How does this action affect Indian country (18 U.S.C. 1151) in Montana?

EPA's approval of the drinking water standards Montana submitted extends to public water systems in Montana with the exception of those public water systems that are within Indian country, as defined in 18 U.S.C. 1151. Indian country lands within the exterior boundaries of the following Indian reservations located within Montana: The Blackfeet, Crow, Flathead, Fort Belknap, Fort Peck, Northern Cheyenne and Rocky Boys Indian Reservations; any land held in trust by the United States for an Indian tribe; and any other areas which are “Indian country” within the meaning of 18 U.S.C. 1151. EPA or eligible Indian tribes, as appropriate, will retain PWSS program responsibilities over public water systems in Indian country.

C. Requesting a Hearing

Any member of the public may request a hearing on this determination within thirty (30) days of this notice. All requests shall include the following information: Name, address, and telephone number of the individual, organization, or other entity requesting a hearing; a brief statement of interest and information to be submitted at the hearing; and a signature of the interested individual or responsible official, if made on behalf of an organization or other entity. Frivolous or insubstantial requests for a hearing may be denied by the RA.

Notice of any hearing shall be given not less than fifteen (15) days prior to the time scheduled for the hearing and will be made by the RA in the Federal Register and in a newspaper of general circulation in the state. A notice will also be sent to both the person(s) requesting the hearing and the state. The hearing notice will include a statement of purpose of the hearing, information regarding time and location for the hearing, and the address and telephone number where interested persons may obtain further information. The RA will issue an order affirming or rescinding the determination upon review of the hearing record.

Please bring this notice to the attention of any persons known by you to have an interest in this determination.
