To calculate the emissions:

- Fill in the spreadsheet completely using the instructions provided in the tool
- After completing the spreadsheet, copy the values calculated by the spreadsheet to the red-bordered text boxes on this page
For each fuel type combusted in each unit, subpart D requires the facility to provide the following:
The total annual CH4 combustion emissions derived from Equation C-10 expressed as CO2 equivalent (CO2e) - this reporting element is only required for fuels listed in Table C-2 [98.36(d)(1)(iii)]
The total annual N2O combustion emissions derived from Equation C-10 expressed as CO2 equivalent (CO2e) - this reporting element is only required for fuels listed in Table C-2 [98.36(d)(1)(iii)]
When finished, click SAVE.
Once you have entered the required fuel emissions information for all units at your facility, you will have finished entering the required fuel emissions information for your facility.
