Laws and Rules
ADEQ conducts rulemaking activities only after approval by the Governor’s Office, in compliance with Governor Doug Ducey’s Executive Order 2017-02 and the Secretary of State’s regulations on rulemaking. A Notice of Docket Opening (NDO) published in the Arizona Administrative Register (A.A.R.) is the first step in rulemaking and may precede one or more informal stakeholder meetings.
A Notice of Proposed Rulemaking (NPRM) is published in the A.A.R. to open the formal public comment period and announce any related public hearing. The NPRM shows language to be deleted in overstrike and language to be added in underline. After the comment period closes, ADEQ prepares a Responsiveness Summary and may make changes to the proposed rule. ADEQ delivers a Notice of Final Rulemaking (NFRM) to the Governor’s Regulatory Review Council (GRRC) for consideration at its Study Session and Meeting. If GRRC approves the NFRM, ADEQ delivers it to the Secretary of State’s (SOS) Office for publication in the A.A.R.
Each rule capsule will be removed 30 days after publication of the Notice of Final Rulemaking in the Arizona Administrative Register. Periodically the SOS updates the Arizona Administrative Code, showing the final text of the rule. The rule capsules summarize activities by Division on each rule in process.
