Steps for Obtaining an Air Permit

All sources of air emissions in Colorado are required to obtain a construction permit unless they are specifically exempted by the provisions of Regulation No. 3. The Construction Permit Unit, located within the Stationary Sources Program of the Colorado Department of Public Health and Environment, issues construction permits to commercial and industrial air pollution sources in Colorado in order to ensure compliance with air quality regulations. The permitting process and requirements involve a two-phased approach. The first phase requires the source to report air emissions through the submission of an Air Pollutant Emission Notice (APEN). For sources with air emissions exceeding permitting thresholds, the second phase involves the issuing of an air permit.

 

The steps involved in submitting an Air Pollutant Emission Notice (APEN) and obtaining an air permit are described below. The Division realizes that some of these requirements may be difficult to understand, and the Small Business Assistance Program has been established to help small businesses comply with these requirements. If you are a small business, please call (303) 692-3175 for information on completing the application and supplemental forms.
