Listed below are several example calculations for Group 2 Grain Elevators that can be used as reference when completing the Minor Source Emission Inventory. All calculations are provided as PDF files, so you will need to have Adobe Acrobat Reader in order to view them.

Potential emissions from all processes at Group 2 Grain Elevators should be calculated using the Grain PTE Tool calculations attached in the Iowa DNR Air Quality Construction Permit for Group 2 Grain Elevators.

Actual emissions from all processes at Group 2 Grain Elevators should be calculated using actual throughput data from the applicable emission year.
