    Public Water System Supervision Program Revisions for the Navajo
    Nation

    AGENCY: Environmental Protection Agency (EPA).

    ACTION: Notice of tentative approval.

    -----------------------------------------------------------------------

    SUMMARY: Notice is hereby given that the Navajo Nation revised its
    approved Public Water System Supervision (PWSS) Program under the
    federal Safe Drinking Water Act (SDWA) by adopting the Arsenic Rule,
    Consumer Confidence Report (CCR) Rule, Filter Backwash Recycling Rule
    (FBRR), Lead and Copper Rule--Minor Revisions (LCR-MR), and Stage 1
    Disinfectants and Disinfection Byproducts (DBP) Rule. The Environmental
    Protection Agency (EPA) has determined that these revisions by the
    Navajo Nation are no less stringent than the corresponding Federal
    regulations and otherwise meet applicable SDWA primacy requirements.
    Therefore, the EPA intends to approve these revisions to the Navajo
    Nation's PWSS Program.

    DATES: Request for a public hearing must be received on or before
    September 28, 2020.

    ADDRESSES: Information submitted by the Navajo Nation relating to this
    determination are available for inspection on http://www.navajoepa.org.

    SUPPLEMENTARY INFORMATION:
        Background. The EPA approved the Navajo Nation's original
    application for PWSS Program primary enforcement authority on October
    23, 2000 (65 FR 66541). Primacy states such as the Navajo Nation must
    adopt and submit for approval to EPA all new and revised national
    primary drinking water regulations. Since that initial approval, EPA
    has worked with the Navajo Nation to review and approve various
    revisions to Navajo's primacy program. For the revisions covered by
    this action, EPA published the latest iteration of the Arsenic Rule in
    the Federal Register on January 22, 2001 (66 FR 6976) and promulgated
    this rule at 40 CFR part 141 Subpart G; published the CCR Rule on
    August 19, 1998 (63 FR 44512) and promulgated this rule at 40 CFR part
    141 Subpart O; published the FBRR on June 8, 2001 (66 FR 31086) and
    promulgated this rule at 40 CFR part 141 Subpart P; published the LCR-
    MR to the 1991 Lead and Cooper Rule on January 12, 2000 (65 FR 1950)
    and promulgated at 40 CFR part 141 Subpart I; and published the Stage 1
    DBP Rule on December 16, 1998 (63 FR 69390) and promulgated this rule
    at 40 CFR part 141 Subpart L. The Navajo Nation has incorporated these
    federal drinking water rules by reference into its Navajo Nation
    Primary Drinking Water Regulations (NNPDWRs), and therefore they
    parallel the federal requirements. The relevant citations to the
    NNPDWRs are: Part IV for the Arsenic Rule, Part XII for the CCR Rule,
    Part VIII for the FBRR, Part VII for the LCR-MR, and Part XI for the
    Stage 1 DBP Rule. These are the primacy revisions that the EPA Region 9
    tentatively approves as part of the Navajo PWSS Program.
        Public Process. Any interested party may request a public hearing
    on this determination. A request for a public hearing must be submitted
    by September 28, 2020, to the Regional Administrator (RA) of EPA Region
    9, to the address shown above. Please note on the mailing envelope
    ``Request for

    [[Page 53366]]

    Public Hearing''. The RA may deny frivolous or insubstantial requests
    for a hearing. If a substantial request for a public hearing is made by
    September 28, 2020, EPA Region 9 will hold a public hearing. Any
    request for a public hearing shall include the following information:
    (1) The name, address, and telephone number of the individual,
    organization, or other entity requesting a hearing; (2) a brief
    statement of the requesting person's or organization's interest in the
    RA's determination and a brief statement of the information that the
    requesting person intends to submit at such hearing; and (3) the
    signature of the individual making the request, or, if the request is
    made on behalf of an organization or other entity, the signature of a
    responsible official of the organization or other entity.
        If EPA Region 9 does not receive a timely and substantive request
    for a hearing and the RA does not elect to hold a hearing on his own
    motion, the determination at issue in this notice, the EPA's approval
    shall become final and effective on September 28, 2020, and no further
    public notice will be issued. EPA Region 9 will provide public notice
    of any public hearing held pursuant to a request submitted by an
    interested person or on EPA's own motion. If a public hearing is held,
    EPA Region 9 will issue an order either affirming or rescinding the
    determination. If EPA Region 9 affirms the determination, it will
    become effective as of the date of the order.

        Authority: Section 1413 of the Safe Drinking Water Act, 42
    U.S.C. 300g-2 (1996), and 40 CFR part 142 of the National Primary
    Drinking Water Regulations.

        Dated: August 19, 2020.

    Regional Administrator, EPA Region 9.
