Public Notice Process for New Source Review Permitting Actions

After a permit application has been reviewed and the Air Quality Administrator has reached a proposed decision to approve or disapprove the request, the Division of Air Quality, in accordance with the Wyoming Air Quality Standards and Regulations, will advertise such proposed decision in a newspaper of general circulation in the county in which the source is proposed.  This advertisement will indicate the general nature of the proposed facility, the proposed approval/disapproval of the permit, and a location in the region where the public might inspect the information submitted in support of the requested permit and the Air Quality Division’s analysis of the effect on air quality.  The public will be afforded a 30-day period in which to make comments and recommendations to the Division of Air Quality.

The Wyoming Department of Environmental Quality is now posting electronic copies of the Air Quality Division’s public notice, permit application analysis, and permit application on the Department’s web site for convenience and ease of access.  Electronic copies of the public notice, permit application analysis, and permit application will be available on this web page through the duration of the public comment period.  They will be removed after the comment period closes.
