The Air Quality Control Commission’s procedural rules guide how the commission must run meetings and rulemaking hearings. The commission is considering changes to its procedural rules to improve the rules and rulemaking process. These updates aim to modernize the process and better meet community needs.

• Promote diverse community and stakeholder engagement in rulemakings.
• Reduce the amount of time spent on rulemaking by community members, partners, and commissioners.
• Simplify commission and rulemaking processes.
• Make the procedural rules easier to read.

• The procedural rules apply to all commission meetings and hearings.
• The commission is considering changes to:
  • The rulemaking process.
  • General procedures that apply to all commission meetings, including public comment.
