Linn Iowa EASY Air

Linn Iowa EASY Air is an online permit application portal where facilities located in Linn County, Iowa can submit applications for Authorization to Install permits, Permits to Operate, and select General Permits and Registrations. Businesses operating in Linn County can apply for their local permits in the Linn Iowa EASY Air system, or continue to submit paper applications using the forms located on the Business & Industry Permitting page.  Facilities subject to Title V and/or Prevention of Significant Deterioration (PSD) permitting requirements are required to use the Department of Natural Resources (DNR)-managed Iowa EASY Air system, but may also be required to apply for local construction permits.  

Linn Iowa EASY Air not only stores application data (allowing permit modifications to be made with minimum input from facility users), but also utilizes the Iowa EASY Air system as a baseline.  This shared infrastructure allows data to be shared between the Linn & DNR systems.  Facilities subject to permitting requirements covered by both systems can benefit from this data sharing:  application data in one system will be propagated to the other system within 24 hours of the submittal.

NOTE:  Prevention of Significant Deterioration (PSD) permit applications are submitted through the DNR's Iowa EASY Air system; however, PSD sources in Linn County are also subject to local permitting requirements. Typically, the Air Quality Branch issues Authorization to Install (ATI) permits alongside the PSD permits and do not require an additional permit application package to process. Permits to Operate (PTOs) are required in Linn County following the successful construction and startup of any permitted source, and PSD sources are no exception. Facilities should apply for PTOs for their PSD sources within the Linn Iowa EASY Air system and select "new" or "modified" as the purpose of the application, whichever is more appropriate (not "PSD").
