The following table contains electronic copies of air-related permit applications the department has received and currently is reviewing. The list includes applications for construction permits, also called new source review permits, operating permits and permit-by-rule permits. An application is considered pending from the date it is received until it is closed. An application is closed when the permit is issued, the application is denied or the application is withdrawn by the applicant.

Applications Under Review

This table can be sorted by field (except city, county) by clicking on the column heading. You can also enter criteria in the search boxes* to search for a specific air permit application.

*This is an "and" type search. All search criteria you enter must be met for the permit application to appear in the results. If the permit application you are searching for is not listed in the results, try again using less criteria.
