This page provides step-by-step instructions on how to enter and edit Subpart Z Phosphoric Acid manufacturing 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 WET PROCESS PHOSPHORIC ACID LINES (Lines 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 table
To delete a unit, click the delete icon located in the last column of the 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

Step 4: Enter Phosphate Rock Origin
For type of phosphate rock used in the unit, report the following required information:
- Origin (select from the pick list)
- Annual amount of Phosphoric acid production produced
- Annual arithmetic average percent inorganic carbon OR the annual arithmetic average percent carbon dioxide (derived from monthly sampling records)
- Annual amount of rock consumed
