Updating Air Quality Control Commission Procedural Rules

Español

Update: During its December 2024 meeting, the Air Quality Control Commission updated its procedural rules. The revised procedural rules will impact rulemaking hearings requested after Aug. 1, 2025.

Overview

The Air Quality Control Commission’s procedural rules guide how the commission must run meetings and rulemaking hearings. In its December 2024 meeting, the commission updated its procedural rules to improve the rulemaking process. These updates aim to modernize the process and better meet community needs.

The revised procedural rules aim to achieve several goals, including:

  • Better readability and consistency with current practices.
  • Creating a more robust pre-petition process that encourages more public participation and complies with the Colorado Environmental Justice Act.
  • Allowing more opportunities throughout the rulemaking process for increased communication for better understanding of the rule and to foster transparency.
  • Providing preliminary rule language earlier in the process to the public for comment and feedback.

Through these new changes, the commission aims to enhance diverse community and stakeholder engagement in rulemakings, reduce barriers to participation in rulemakings, and simplify the commission's rulemaking process.

The revised procedural rules will impact rulemaking hearings that are requested after Aug. 1, 2025.

Next steps: Updating the procedural rules guidebook

In 2025, the Air Quality Control Commission plans to update the procedural rules guidebook. The guidebook describes best practices and expectations for how and when outreach should happen. More information about guidebook updates and opportunities for public input will be published on this web page.

Anyone who intends to propose a rule for the commission’s consideration must follow the Colorado Environmental Justice Act for outreach to communities and stakeholders.

Public meetings

The CDPHE Air Pollution Control Division hosted online public meetings in 2024. All Coloradoans were welcome to join, learn more about the procedural rules, and share their ideas and feedback.
