Subpart Q Emissions Information for Units NOT Monitored by CEMS
Note: The Cal e-GGRT help system includes general instruction on using the California GHG reporting tool. However, the help system may not explain differences between California and U.S. EPA reporting requirements. Please refer to the ARB reporting website for California-specific reporting requirements and additional help.

To enter emissions data for a process unit NOT monitored by CEMS for which to enter emissions data, find the unit in the UNITS table and click on the blue OPEN button in the second to last column. You will then be on the "GHG Info" “GHG Info” form for each process type.

Note

If the CO2 process emissions from the selected unit will be estimated using the carbon mass balance method, proceed to Section A - Carbon Mass Balance Method and execute steps A1-A4 for each type of process unit.

If the CO2 process emissions from the selected unit will be estimated using the site-specific emission factor method, proceed to Section B - Site-specific Emission Factor Method and execute steps B1-B2 for each process unit.

Step A2: Input and output substitute data

...

  • Annual mass or volume is based on one or more substitute monthly data values. If this is not selected or is not applicable, you must enter zero, "0" “0” in the box for the number of months with missing data. If you do not remember, you will receive a UNIT level validation message indicating that you have not completed entering data on this form in the validation report.
  • Number of months that missing data procedures were followed, if applicable
  • Method used to develop the substitute data value(s), if applicable. Enter information only if you applied missing data procedures, otherwise leave blank.
  • Carbon content determination method, selected from the following, be sure the method selected is appropriate to the material being tested:
    • Supplier
    • ASTM C25-06
    • ASTM D5373-08
    • ASTM E1915-07a
    • ASTM E1019-08
    • ASM CS-104 UNS No. G10460
    • ISO/TR 15349-3:1998
    • Other (specify)

...

When you have finished entering annual emissions, inputs and outputs and identifying whether substitute data were used to determine mass or volume of input/outputs, click SAVE. You will then return to the Subpart Overview page and you should see the status of data entry for the unit change to "Complete" “Complete” in the Status column in the UNITS table.

...

Repeat Steps B1 until data has been entered for all process units for which emissions were estimated using the site-specific emission factor method.
