Background. EPA approved the State's initial application for PWSS Program primary enforcement authority (“primacy”) on February 27, 1978 (43 FR 8030). Since initial approval, EPA has approved various revisions to Nevada's PWSS Program. For the revisions covered by this action, EPA revised the Arsenic Rule on January 22, 2001 (66 FR 6976). The revisions included a more stringent federal standard for arsenic in drinking water from 0.050 mg/L to 0.010 mg/L to better protect public health. The State submitted its final application to add the Arsenic Rule to its approved PWSS Program on December 30, 2011, followed by an application supplement on February 11, 2021. EPA has determined that the Arsenic Rule was incorporated by reference into the Nevada Administrative Code (NAC), Title 40 Chapter 445A, in a manner that Nevada's regulations are comparable to and no less stringent than the federal requirements. EPA has also determined that State's primacy revision 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 Nevada Attorney General certifying that Nevada's laws and regulations adopted by the State to carry out the program revisions were duly adopted and are enforceable. Therefore, EPA intends to approve the State's revisions as part of its PWSS Program.
