Air Quality Control Commission

Hot topics
  • Next Monthly Commission meeting is scheduled: Friday, May 10, 2019 to begin at 9:00 a.m. in the Sabin/Cleere conference room.
  • Next Executive Committee meeting is scheduled: Thursday, May 16, 2019 to begin at 8:00 a.m. in the Carson conference room.
  • Zero Emission Vehicle (ZEV):

On May 10, 2019, the Colorado Air Quality Control Commission will consider a Request for Hearing to consider adopting a Zero Emission Vehicle (ZEV) program for Colorado. The Commission will accept public comment on May 10 before deciding whether or not to schedule an August 2019 Rulemaking Hearing; therefore, comments on or prior to May 10 should focus on whether the Commission should schedule the rule for hearing (or not) rather than on whether (or not) the Commission should adopt the ZEV rule in August. 

Public comments  on May 10 will not be considered by the Commission as part of the decision in August on whether to adopt the ZEV program; if the Commission schedules a rulemaking for August, there will be a separate public comment period following the publication of notice for the rulemaking. 

The Commission strongly encourages written comments in advance of May 10. If you would like to provide oral comments, you must sign up in person by 9:30 am on May 10. Public comments are likely to be limited to 2 minutes per person (although if there are more commenters than anticipated the Commission may need to shorten the time allotment). Anyone wishing to donate their time to another person to speak on their behalf must be physically present in order to do so. Remote comments will not be an option.

  • The Colorado Low Emission Automobile Regulation (CLEAR), also know as the Low Emission Vehicle (LEV) standards, was adopted on November 16, 2018. If you are interested in reviewing the hearing documents you may find them at Regulation Number 20.

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
