This page provides step-by-step instructions on how to enter and edit Subpart Q Iron and Steel Production process unit information for units that are monitored by CEMS.
Under Subpart Q, "process units" may include any of the following:
- Taconite indurating furnace
- Basic oxygen process furnace
- Non-recovery coke oven battery
- Sinter process
- Electric arc furnace (EAF)
- Decarburization vessel
- Direct reduction furnace
To add a process unit that is monitored by CEMS, find the UNIT SUMMARY (Units Monitored by CEMS) table on the Subpart Overview page and click the link titled "ADD a CEMS Unit." When you report emissions information later you will have the opportunity to indicate or identify if a CEMS Monitoring Location (CML) is monitoring multiple units that may share a common stack.
To later edit information identifying a process unit, click the edit icon or the Name/ID link located in the first column of the table.
To delete a process unit, click the delete icon or red “x” located in the last column of the table.
