Air Permits for Colorado Business and Industry

Any business in Colorado that emits air pollution may be required to report its emissions and apply for a permit to emit. The type of permit needed is determined by the volume and type of emissions.

Obtaining an Air Permit

• Construction Permits 
  • New and existing businesses in Colorado that emit air pollutants above certain threshold levels may trigger the need for an air permit called a "Construction Permit". These are issued through the Air Pollution Construction Permit Unit.
• Construction Permits for Oil and Gas Facilities
  • The Oil and Gas industry construction permitting process has been developed specifically for that industry.
• Operating Permits
  
  • All major sources of air emissions in Colorado are required to obtain an Operating Permit. These sources emit pollutants beyond the level required for a construction permit only. New major sources must first obtain a construction permit, and must apply for an operating permit within 12 months of commencing operation. Also called the Title V Operating Permit Program.
