DES MOINES – The DNR Air Quality Bureau has the following draft permits up for review. The permits help protect Iowans’ health and air quality. DNR’s permitting staff review each permit application to ensure facilities comply with state and federal air quality requirements. We encourage public comments on draft permits, providing help on how to make effective comments. Submit written comments to the assigned permit writer before 4:30 p.m. on the last day of the comment period. DNR considers public comments before finalizing the permits.

Construction Permits
DNR engineers review and issue construction permits to facilities before they build new or modify existing sources of air pollution. The public may review the following air quality construction permits available online at OR through the EASY Air Public Inquiry Portal and then click the Public Notice tab.

Black Hawk County
John Deere Product Engineering Center (PEC) – 3725 Cedar Heights Drive, Cedar Falls. Project No. 20-280.

The current project is to increase the maximum rated fuel capacity descriptions in 18 Liter (L) displacement test cells to reflect the maximum fuel consumption during planned engine testing programs in various test cell permits at the facility. In addition, the use of larger 18 Liter (L) engines was removed from Emission Unit (EU) 2A02 permits, as this unit is not increasing the fuel consumption rate. Finally, EU 2A02 was removed from multiple permits and the nitrogen oxide (NOx) emissions bubble limit was lowered to remove NOx lb./hr. emissions of EU 2A02 from the bubble limit. The compliance testing requirements were maintained in the permits since the company has not completed the testing on these units to demonstrate compliance. Comments during the public comment period are limited to these proposed permit amendments. The public comment period ends Jan. 8, 2021.
