Subpart P Process Unit Information for Units 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.


This page provides step-by-step instructions on how to enter and edit Subpart P Hydrogen Production process unit information for units that are monitored by a Continuous Emissions Monitoring System (CEMS).

Step 1: Add a unit

To add a unit that is monitored by a CEMS, find the HYDROGEN PRODUCTIONUNITS (Units monitored by CEMS) table on the Subpart Overview page and click the link titled "ADD a Unit Monitored by CEMS"

To edit a unit, click the edit icon or the Name/ID link located in the first column of the HYDROGEN PRODUCTION UNITS (Units monitored by CEMS) table

To delete a unit, click the delete icon located in the last column of the HYDROGEN PROCESSING UNITS (Units monitored by CEMS) table

Step 2: Indicate CEMS utilization for a unit

For each process unit, confirm whether or not the process unit utilizes CEMS

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)

The CEMS response may be changed here and the unit information will be relocated to the appropriate table on the Subpart Overview page

When finished, click SAVE

  • The quantity of hydrogen produced (in metric tons) [98.166(a)(2) and 98.166(b)(3)]
  • The quantity of ammonia produced (in metric tons) [98.166(a)(3) 98.166(b)(4)]
