    SUPPLEMENTARY INFORMATION:

    Background. EPA approved the State's initial application for PWSS Program primary enforcement authority (“primacy”) on October 20, 1977 (42 FR 47244). Since initial approval, EPA has approved various revisions to Hawaii's PWSS Program. For the revisions covered by this action, the EPA revised the Radionuclides Rule on December 7, 2000 (66 FR 76708), which had been in effect since 1977. The revisions set new monitoring provisions for community water systems; retain the existing maximum contaminant levels (MCLs) for combined radium-226 and radium-228, gross alpha particle radioactivity, and beta particle and photon activity; and regulate uranium for the first time. EPA has determined that the Radionuclides Rule was adopted verbatim into the Hawaii Administrative Rules (HAR), Title 11, Chapter 20, in a manner that Hawaii's regulations are comparable to and no less stringent than federal requirements. EPA has also determined that the State's primacy revision application meets all of the regulatory requirements for approval, as set forth in 40 CFR 142.12, including a side-by-side comparison of the Federal requirements and the corresponding State authorities, additional materials to support special primacy requirements of 40 CFR 142.16, and a statement by the Hawaii Attorney General certifying that Hawaii's laws and regulations to carry out the program revisions were duly adopted and are enforceable. Therefore, EPA is tentatively approving the State's revisions as part of Hawaii's PWSS Program.

    Public Process. Any interested party may request a public hearing on this determination. A request for a public hearing must be received or postmarked before September 13, 2021, and addressed to the Regional Administrator at the EPA Region 9, via the following email address: R9dw-program@epa.gov. Please note, “State Primacy Rule Determination” in the subject line of the email. The Regional Administrator may deny frivolous or insubstantial requests for a hearing.
