Air Quality Control Commission

Air Quality Control Commission -- Meetings Going Remote
Due to the need for additional meeting room space at the Colorado Department of Public Health and Environment (CDPHE) for its COVID-19 response activities, including the use of the Sabin-Cleere Rooms, we will no longer be able to host Air Quality Control Commission (AQCC) meetings at CDPHE. In addition, we are committed to continuing to provide an equal opportunity for people who may be at risk for developing severe illness in response to COVID-19 to participate in public processes regardless of their concerns about susceptibility or exposure to COVID-19. For these reasons and also to practice social distancing in the event it becomes necessary and to demonstrate that it can succeed, the AQCC will be conducting all commission/board meetings, prehearing conferences, and status conferences as remote meetings only. This will take effect March 18, and at this time we anticipate it will continue through at least the end of April. Opportunity will be made available for parties to rulemaking hearings and interested members of the public to participate remotely in the meeting and provide testimony and public comment and will be posted on this website.

Request for Pause on Environmental Regulatory and Policy Work
The Colorado Department of Public Health and Environment received several letters requesting that the department pause its environmental regulation and policy activities to allow facilities and operators to focus on maintaining critical operations and compliance. Due to the complications of delaying all regulatory and policy work for several months, and the importance of assuring public health and environmental protection, at this time the department intends that the majority of the scheduled regulatory and policy activities continue as planned with the exception of those identified within this document.

Annual Report to the Public
Colorado’s air quality management program relies upon several organizations within the state and the country, as well as its citizens, to achieve and maintain air quality. The commission works closely with Colorado’s Air Pollution Control Division to adopt and implement air quality management programs in the state. Also closely involved in the state’s air quality management program are the U.S. Environmental Protection Agency and federal land managers, the governor-designated air quality planning agencies, city and county health departments, the regulated community and citizens of Colorado. Colorado, like many states, has experienced numerous issues with air quality, but has been successful in providing good public health protection and improving air quality. Examples of this can be found in the Colorado Air Quality Control Commission’s Annual Report to the Public. An archive of additional reports are maintained by the Commission Office and is available upon request at

​Hearing guidance documents
The Guidebooks have been prepared to provide members of the public and other interested parties information on the hearing processes, known as “rulemaking”, "adjudication", and "informational or public". Following are our guidance documents. Templates referenced are available upon request through the commission office.

Guidebook:  Rulemaking Hearing
The office of the Air Quality Control Commission held a Public Participation Workshop on September 4, 2019 at the Broomfield Library Auditorium. The workshop provided members of the public with information on how to most effectively participate in commission rulemaking proceedings, especially those regarding oil and gas activities. This same information was also provided at a public meeting held at the Grand Junction City Hall Auditorium on September 10, 2019.
If you wish to participate in the commission’s hearing processes, you are responsible for reviewing relevant statutes and rules that apply to the hearing process to make sure you understand your rights and responsibilities.  More details about these processes may be found in the Commission’s Procedural Rules, 5 CCR 1001-1, the Air Pollution Prevention and Control Act (APPCA), C.R.S. §25-7-101, et seq., and the Colorado Administrative Procedures Act (APA), C.R.S. §24-4-103.
