Table of Contents

Did you know that on January 1, 2023, air permit applications and air emissions reporting documents are required to be submitted electronically? 

While you have had the ability to submit electronically for a while now, the Department of Natural Resources (DNR) will soon be requiring electronic submission of air permit applications through the Iowa Environmental Application System for Air (Iowa EASY Air) and emission inventories via the State and Local Emissions Inventory System (SLEIS). 

Who Has to Report Using These Systems? 

Any Iowa business that is part of the air quality regulated community and has to complete and file reports, notifications and permit applications. 

Iowa EASY Air is the electronic permit application system for construction and Title V operating permit applications. In Iowa, all new or modified equipment that emits a regulated air pollutant must have a construction permit unless otherwise exempt.

SLEIS is a web-based emissions inventory reporting system used by industry to manage facility and equipment information and to report point source emissions data to DNR.

TIP: The IWRC and DNR will contact any business that is required to report. 

Benefits to Electronic Submission

Iowa EASY Air and SLEIS are both designed to make reporting and submitting applications easy, fast and accurate. 

Other benefits include: 

  • Reporting is easier and more efficient
  • Can submit information from any location at any time
  • Increases data accuracy
  • Speeds up DNR’s ability to issue permits
  • Saves time & money for businesses & DNR

Expert Advice

DON’T WAIT UNTIL THE DEADLINE - The Emissions Inventory deadline is May 15. Plan ahead to request assistance. Allowing yourself enough time to collect the necessary data, calculate your emissions and get everything entered and submitted into SLEIS is important. 

BE PROACTIVE - If new equipment is added or modifications to existing equipment is made, make sure to think ahead and review if air quality permitting requirements are needed or existing permits need to be updated.
