The rule making process follows these steps to approve any new regulation:

1. APCD proposes a draft regulation that is typically released to stakeholders for informal comments.
2. A committee of the Air Pollution Control Board approves the draft, beginning the formal public review process.
3. A legal notice is published, announcing the beginning of a 30-day written formal public comment period.
4. The Board then schedules a public hearing on the proposed regulation.
5. Following the public hearing and consideration of all public comments, the Board may:
1. Adopt the proposed regulation;
2. Reject the proposed regulation;
3. Modify the proposed regulation;
4. Seek additional public comment; or
5. Take no action.
6. After adoption, APCD begins implementing the new regulation.
