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.
