The Air Quality Division (AQD) Monitoring Section has the responsibility to protect, conserve, and enhance the quality of Wyoming’s air resource.  The Monitoring Section helps ensure the ambient air quality in the State of Wyoming is maintained in accordance with the National Ambient Air Quality Standards (NAAQS).  To carry out this goal, AQD operates and maintains a network of ambient air quality monitors and requires industrial pollution sources to conduct source specific ambient air monitoring.

Ambient Air Monitoring Quarterly Report Submittals

The Air Quality Division has created a website, Air Quality File Upload Utility, to help upload all of the Industrial Ambient Air Monitoring Reports submitted quarterly and annually.  This website is the exclusive portal for industry to submit electronic data to the Monitoring Program.  Please remember Quarterly Reports are due to AQD sixty days after the end of each quarter.  If there are any questions or problems while using this system, please contact Carrie Chitty at carrie.chitty@wyo.gov.
