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 CEMS.

Step 1: Add a unit

To add a unit that is monitored by a CEMS, find the HYDROGEN PRODUCTION UNITS (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 PRODUCTION 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
