Air Quality Programs


In order to ensure that Wyoming government, business and industrial operators are in compliance with the Wyoming Air Quality Standards and Regulations (WAQSR), the Air Quality Division conducts inspections and uses regulatory inspection checklists. In order to ensure compliance, AQD issues both formal and informal enforcement actions.

Emissions Inventories

The Wyoming Department of Environmental Quality monitors and collects actual emissions data in accordance with federal regulations. After review, this data is uploaded to the appropriate database. Emissions data may be updated when new information is received. Actual point source emissions data is made available at after the emissions inventories are approved.  

Impact and Open Air

IMPACT is the Wyoming Air Quality Division’s (AQD) online Inventory, Monitoring, Permitting, And Compliance Tracking (IMPACT) data system.


We ensure the ambient air quality in Wyoming is maintained in accordance with the National Ambient Air Quality Standards. To carry out this goal, we operate and maintain a network of ambient air quality monitors and require industrial pollution sources to conduct source specific ambient air monitoring.  

New Source Review

The New Source Review program pertains to new construction projects or construction projects modifying existing facilities or sources that may cause air contaminants to be issued or increase from their current levels.


Ozone is a gas comprised of three atoms of oxygen that is found both in the Earth’s upper atmosphere and at ground level. According to the US Environmental Protection Agency, ozone can be good or bad, depending on where it is found.  

Rule Development

The Air Quality Division State Implementation Plan and Rule Development section is responsible for developing federally approvable plans and rules necessary to ensure that the State of Wyoming retains primacy in regulating sources of air pollution as required under the Clean Air Act (CAA).

Smoke Management and Open Burning

The AQD manages air emissions from all fires under two very distinct and separate programs throughout Wyoming: Smoke Management and Open Burning. 

Title V

A Title V Operating Permit consolidates all applicable air quality regulatory requirements into a single, legally-enforceable document. These permits are designed to improve compliance by clarifying what air quality regulations apply to a facility.
