The following table contains electronic copies of air permits issued by the department since Jan. 1, 1997. The list includes construction permits, also called new source review permits, and operating permits. The list also includes permit-by-rule permits. The department will add air permits issued before Jan. 1, 1997, to the table below as time and staffing allow. A list of pending air permits and air permits issued before 1997 are available in the separate search systems listed below. If you cannot find the information you are looking for, please submit an Open Records/ Sunshine Law Request.

To sort the table below by field, click on the Facility, Site ID, Permit Type, Permit Number or Date Issued column headings in the table. You can also enter criteria in the search boxes to search for a specific air permit.

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