AZ HB2624

Amends Arizona's informal appeals process for environmental quality decisions by clarifying that the process applies to written interim decisions issued under title 49 and expanding the definition of "written interim decision" to include specific technical and scientific interpretation issues.

Modifies the qualified professional requirements to include individuals with a juris doctor degree in addition to science/engineering degrees, and specifies that professional registration is "highly preferred, if applicable."

Consolidates underground storage tank (UST) informal appeal provisions by redirecting UST appeals to the general section 49-116 process rather than maintaining a separate section 49-1091 appeals procedure.

Clarifies that if the director issues a written resolution of general applicability during dispute resolution, the department must issue a substantive policy statement or commence rulemaking under title 41, chapter 6.

Updates references throughout the statute to align UST appeal procedures with the consolidated informal appeals process in section 49-116, including provisions for time tolling, fee reimbursement, and the department's response requirements.
