Underground Injection Control (UIC) Rulemaking

Summary:

ADEQ is required under ARS §§ 49-203(5) and 49-257.01(A) to adopt a permit program for underground injection control (UIC), as administered under the Safe Drinking Water Act (SDWA; 42 USC § 300h et seq.). Any UIC rules promulgated by the State of Arizona shall not have the force and effect of law until the US Environmental Protection Agency (EPA) approves the transfer of primary enforcement authority (“Primacy”) through EPA’s publication of a final rule granting ADEQ Primacy in the Federal Register (see 40 CFR § 145.31). ADEQ proposes a new regulatory framework to articulate compliance expectations, mandate regulatory duties, and identify certain rights of those regulated through the state UIC program. The Governor’s office approved an exemption from Executive Order 2018-02 on May 7, 2018.
