Adding or Updating Fuel Emissions Information for Each Unit

Starting on the Subpart D Overview page, find the configuration type for which you would like to enter emissions information in the SOURCE SUMMARY table and click OPEN.

To enter emissions data by fuel type, find the fuel type for which you would like to enter fuel emissions data in the FUEL-SPECIFIC CH4 AND N2O EMISSIONS INFORMATION table and click OPEN.

Cal e-GGRT will calculate the following required data based on provided inputs:

• The total annual CH₄ mass emissions derived from Equation C-10 in metric tons CH₄ and in metric tons CO₂e. [98.36(b)(9)(iii), 98.36(c)(2)(ix)]
• The total annual N₂O mass emissions derived from Equation C-10 in metric tons N₂O and in metric tons CO₂e. [98.36(b)(9)(iii), 98.36(c)(2)(ix)]

Use the radio buttons to elect to report emissions using the Cal e-GGRT calculated value or to enter your own value manually. If you elect to report manually calculated emissions values, use the the appropriate radio buttons and data fields. Otherwise, the radio buttons will default to using the calculated results.

When finished, click NEXT.

Use the Equation Inputs to enter required inputs:

• Cumulative annual heat input from fuel combustion
• Annual mass or volume of fuel combusted
• Emission factor (if the fuel was entered manually)

When finished, click NEXT. On the Fuel-specific Emissions screen, click FINISHED to save the data entered for this fuel.

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.
