Subpart AA Process Unit 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.


The text below describes how to add a Unit or Furnace. The process to edit an existing Unit or Furnace is essentially similar.

Step 1: Adding, Modifying or Deleting Process Unit Information for Units NOT Monitored by CEMS at this Facility

Starting on the Subpart AA Overview page, click the link titled "ADD a Unit or Furnace".

To modify an existing unit or furnace, click on the edit icon or the Name/ID link, which is the first column in the UNIT AND FURNACE SUMMARY table.

To delete an existing unit or furnace, click on the delete icon, which is the last column in the UNIT AND FURNACE SUMMARY table.

Step 2: Indicate CEMS Utilization for a Unit

For each unit or furnace indicate that the emissions are not measured by operating and maintaining a Continuous Emissions Monitoring System (CEMS). Click either yes or No.

Note that when adding a new unit you are prompted to answer the CEMS question immediately (the answer to this question will default to “No” for units added using the “ADD a Unit” link and will default to “Yes” for units added using the “ADD a Unit Monitored by CEMS” link)

When you are finished, click NEXT.
