Emissions and Fee Calculation

Permits – Most of the information needed to complete an emissions report can be found in the facility’s permit(s). The department takes the information from issued permits and preloads the information into Missouri Emissions Inventory System (MoEIS) to make completing the emissions report as easy as possible.

Stack Tests – Stack tests are a common source for emission factors. Only stack tests that have been verified by department staff should be used in the emissions reports.

AP-42/WebFire – EPA has a database of emission factors for a large number of processes. When more appropriate factors are not available, these can be used in the emissions reports. 

• Emissions Reporting: Hazardous Air Pollutants (HAP) Worksheet Troubleshooting - Outlines important items to review and update when reporting HAP emissions.
• Section 112 Hazardous Air Pollutants (HAP) List - Contains the reportable HAPs and identifies whether they should be reported as VOC, PM or HAPs. HAPs that are reported as VOC or PM still need to be itemized in the HAP worksheet and updated when completing a full report.
• Exempt Volatile Organic Compounds (VOC) List - Chemicals and compounds that do not need to be included in VOC calculations.
• Emission Inventory Questionnaire (EIQ) Forms Workbook

   - For those unable to use Missouri Emissions Inventory System (MoEIS), this contains all forms needed to complete the emissions report and completes the calculations.

• Landfill Emissions Calculation Tool (version 2)

   - Should be used to calculate landfill emissions. Use the outputs to update your throughputs, emission factors and HAP worksheets in Missouri Emissions Inventory System (MoEIS).

The emission fee is $55 per ton for the 2022 emission year. CO, PM_2.5 and NH3 are not chargeable pollutants.
