Missouri's emissions reporting and fee rule, 10 CSR 10-6.110, aligns with federal reporting rules. Full emissions inventory questionnaire (EIQ) reports require updated activity and emissions data for the emission year being reported, but the simplified one-page reduced EIQ report uses emissions from the most recent full EIQ to represent emissions for the year being reported.

Full EIQ reporting requirements by permit type:

  • Part 70: Full report every year.
  • Intermediate: Full report every three years on fixed cycle, for example 2014, 2017, etc. A full report is necessary for an interim year if emissions change by five tons or more since the last full report.
  • All others: After first full report, only if emissions change by five tons or more.

The report due date is April 1, with an automatic extension to May 1 if reporting online via MoEIS.

The payment due date is June 1.

The emission fee has increased to $48 per ton of emissions. The increased fee applies to emission years 2015 and beyond.

If our records indicate that you may qualify for a reduced reporting form, we will send you this one page form in the beginning of January following the emission year. If you have questions, contact the Missouri Department of Natural Resources' Air Pollution Control Program by email or call 573-751-4817.
