Construction Permit Amnesty for Engines

On October 23, 2013, the Iowa DNR, along with the Polk County and Linn CountyAir Quality Divisions, initiated an amnesty program for engines. The intent of the amnesty was to provide Iowa businesses an opportunity to "catch up on" air quality permitting requirements they had missed, without the risk of potential enforcement actions and penalties.

The amnesty period ended on April 23, 2014. DNR is pleased to report that 110 Iowa businesses, operating 127 engines, took advantage of the amnesty and submitted the past due permit applications, registrations, or permit exemption information.

Results of DNR Air Quality Bureau's 6-month amnesty period for as-built engines (includes Linn County and Polk County):

Requirement Number of facilities Number of Engines
Obtain Construction Permit 44 53
Submit Small Engine Registration 60 64
Submit Exemption "g" Notification 6 10
Totals 110 127
