Western Iowa Minor Source Emmission Inventory Reports Due May 15
Posted: 01/26/2012
Minor source facilities located in the western third of Iowa (counties listed below) must submit their Minor Source Emission Inventory (MSEI) for calendar year 2011 emissions to the Iowa Department of Natural Resources (IDNR) Air Quality Bureau by May 15, 2012.

Letters have been sent to facilities required to complete this year’s report. A complete air pollutant inventory is required by Iowa Administrative Code (567) sub rule IAC 21.1(3). The data collected is used to track Iowa's progress towards meeting national air quality standards, perform regional and local air pollution dispersion modeling, develop control and maintenance strategies required by the Clean Air Act, and identify emission levels and trends throughout the state.

The Iowa DNR will offer Minor Source Emission Inventory SPARS training webinars beginning next month. Facilities intending to submit their MSEI report electronically are strongly encouraged to attend a SPARS training webinar. SPARS training webinars will be held February 29, March 1, March 7, and March 8. Additional information regarding the webinars is available at http://www.iowadnr.gov/InsideDNR/RegulatoryAir/EmissionsInventory/EmissionsInvTraining.aspx.
 
Facilities with less than 100 employees may also contact the Iowa Air Emissions Assistance Program (IAEAP) at the University of Northern Iowa for free training in order to complete their Minor Source Emissions Inventory.
