DES MOINES – The DNR Air Quality Bureau has the following draft permits up for review. The permits help protect Iowans’ health and the air where we live. DNR’s permitting staff review the applications to ensure facilities comply with state and federal air quality standards. The public has the right and is encouraged to comment on draft permits. DNR considers public comments before finalizing the permits. Submit comments in writing to the assigned permit writer before 4:30 p.m. on the last day of the public comment period. 

Title V Operating Permits
Title V Operating permits are reviewed and re-issued every five years. Facilities with a Title V permit have the potential to emit large amounts of air pollutants compared to other facilities. The five-year reviews are a federal requirement and ensure adequate monitoring is included in the permit. The DNR plans to issue Title V Operating Permits for the following facilities.  Find permit details at
