Title V Facilities' Emissions Reports due March 31, 2017

Facilities subject to Title V of the federal Clean Air Act must submit their emissions inventories for 2016 to the Iowa Department of Natural Resources (DNR) Air Quality Bureau by March 31, 2017.

Title V emission inventory forms can be downloaded from DNR web site at Two copies of Forms 1.0, 4.0, 5.0 Part 3, and supporting calculations are required for Title V Emissions Inventory reports. If your facility is located in Linn County or Polk County, one additional copy must be sent to the corresponding county directly. To simplify the emissions reporting requirement, the DNR recommends using the State & Local Emissions Inventory System (SLEIS). If you use SLEIS to submit your inventory electronically, you do not need to mail hard copies to DNR, Linn County or Polk County. For assistance regarding Emissions Inventory or Fee Payment (due July 1, 2017), please contact Weston Li at (515) 725-9580 or

The Annual Compliance Certification and the Semi-Annual Monitoring Report are due March 31, 2017 if your initial Title V permit was issued prior to January 1, 2017. Contact Dennis Thielen at (515) 725-9545 or if you have questions about these reports.
