This page provides step-by-step instructions on how to enter and edit Subpart K Ferroalloy Production furnace information.
Step 1: Add an electric arc furnace (EAF)
To add an EAF that is monitored by a CEMS, find the ELECTRIC ARC FURNACES (Furnaces Monitored by CEMS) table on the Subpart Overview page and click the link titled "ADD a Furnace Monitored by CEMS."
To edit or update identification information for an EAF, click the edit icon or the blue hyperlinked Name/ID link located in the first column of the table.
To delete an EAF, click the delete icon or red “x” located in the last column of the table.

Step 2: Indicate CEMS utilization for a furnace
For each EAF, confirm whether or not the furnace utilizes CEMS.
Note that when adding a new EAF you are prompted to answer the CEMS question immediately (the answer to this question will default to “No” for EAF added using the “ADD a Furnace” link and will default to “Yes” for units added using the “ADD a Furnace Monitored by CEMS” link).
The CEMS response may be changed here and the EAF information will be relocated to the appropriate table on the Subpart Overview page.
When finished, click SAVE. You will then be directed to the next Add/Edit a Unit form.

Step 3: Enter required information for an EAF
For each EAF monitored by CEMS at your facility, Subpart K requires you to report a unique name or identifier, plus optional description for the EAF (see also About Unique Unit Names).
When you are finished entering the required information for an EAF, click SAVE. You will then be direct back to the Subpart Overview form. You should now see the furnace you just identified listed in the ELECTRIC ARC FURNACES (Furnaces Monitored by CEMS) table.

Step 4: Enter required annual production of Ferroalloy Products
After successfully adding an EAF monitored by CEMS, it will appear on the Subpart Overview Page. Clicking on the "OPEN " link will allow for the entry of the annual production of Ferroalloy Products. For each EAF listed below that is monitored by CEMS, enter the annual production for each Ferroalloy Product. If the specific electric arc furnace did not produce any of a given ferroalloy product, simply un-check the box, and the numeric entry box will disappear.
List of Ferroalloy Products

Step 5: Repeat Steps 1-4
Repeat Steps 1-4 until all EAFs and their annual production have been added for your facility and you see all EAFs monitored by CEMS listed in the ELECTRIC ARC FURNACES (Furnaces Monitored by CEMS) table.
