Subpart K consists of facilities that use pyrometallurgical techniques to produce any of the following metals: ferrochromium, ferromanganese, ferromolybdenum, ferronickel, ferrosilicon, ferrotitanium, ferrotungsten, ferrovanadium, silicomanganese, or silicon metal.

This page provides an overview of subtopics that are central to Subpart K reporting. This information is entered from the e-GGRT Subpart K Overview web form shown below. Each topic represents a key web form(s) where you need to enter information:

• Subpart K Summary Information for this Facility
• Subpart K Furnace Information for Furnaces NOT Monitored by CEMS
• Subpart K Furnace Information for Furnaces Monitored by CEMS  
• Subpart K Emissions Information for Furnaces NOT Monitored by CEMS
• Subpart K Emissions Information for Furnaces Monitored by CEMS
• Subpart K Entering Equation Inputs Using IVT
• Subpart K Validation Report

Subpart K Summary Information for this Facility

Back to Top

Subpart K Furnace Information

The required information and forms entered into e-GGRT are different for electric arc furnaces (EAFs) that are monitored by a Continuous Emissions Monitoring System (CEMS) and for EAFs that are NOT monitored by a CEMS.

As a result, separate help content has been created in this subpart for entering EAF information for EAFs monitored by a CEMS and for EAFs NOT monitored by a CEMS.

For each EAF NOT monitored by a CEMS at your facility, Subpart K requires you to report the following information:

• A unique name or identifier, plus optional description for this EAF (see also About Unique Unit Names)
• The following data for each input and output associated with the EAF:
  • A unique name or identifier
  • The general type of input or output

For each EAF monitored by a 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).

Subpart K Emissions Information

The required emissions information, and the manner by which it is entered into e-GGRT, is different for EAFs that are monitored by a CEMS and for EAFs that are NOT monitored by a CEMS.

As a result, separate help content has been created in this subpart for entering emissions information for EAFs monitored by a CEMS and for EAFs NOT monitored by a CEMS.

For each EAF that is NOT monitored by a CEMS at your facility, Subpart K requires the following emissions information:

• The annual CO₂ process emissions (the output of Equation K-1, in metric tons)  (for RY2014 and later years enter Eq. K-1 inputs using IVT to calculate CO2 process emissions)
• For each EAF used for the production of a ferroalloy listed in Table K-1, the annual CH4 process emissions (the output of Equation K-3, in metric tons) (for RY2014 and later years enter Eq. K-3 inputs using IVT to calculate CH4 process emissions)*
• For each Input and Output assigned to an electric arc furnace, Subpart K collects the following data:
  • The method used to determine carbon content (Provided by supplier, ASTM E1941-04, ASTM D5373-08, or ASTM C25-06)
  • An indication if a missing data procedure was used or analysis was repeated to determine carbon content
  • The procedure used to develop substitute data for monthly mass, if applicable (Purchase records or Other)
  • The number of months that missing data procedures were followed to determine monthly mass

*Note, reporting of CH4 process emissions is only required for ferroalloy types listed in Table K-1. If you do not produce a ferroalloy type listed in this table, enter “0” for your emissions.

Where EAFs are monitored by a CEMS, provide the following information for each CEMS Monitoring Location (CML):

• A unique unit name or identifier for the CML (see also About Unique Unit Names)
• An optional description or label for the CML
• The configuration of processes or process units that are monitored by the CML:
  • Single process or process unit that exhausts to a dedicated stack
  • Multiple processes or process units that share a common stack
  • Process or process unit that shares a common stack with one or more stationary fuel combustion units
• The name of each fuel combusted in the unit(s) monitored by the CEMS
• The Tier 4/CEMS methodology start and end dates
• The cumulative total of hourly CO₂ mass emissions for each quarter of the reporting year (metric tons) (Do not cumulate emissions data between quarters)
• The total annual CO₂ mass emissions measured by the CEMS (metric tons)
• An indication of whether emissions reported for the CEMS include emissions calculated according to 98.33(a)(4)(viii) for a slipstream that bypassed the CEMS
• The total annual biogenic CO₂ emissions from the combustion of all biomass fuels combined (metric tons) (if not applicable, enter '0')
• The total annual non-biogenic CO₂ emissions which includes fossil fuel, sorbent, and process CO₂ emissions (metric tons)
• The total annual CH₄ and N₂O emissions associated with the combustion of all Table C-2 fuels combusted in all processes/process units monitored by the CEMS derived from application of Equation C-10 (metric tons) (if there are no combustion emissions in this CML, please enter '0')
• The total number of source operating hours in the reporting year
• The total operating hours in which a substitute data value was used in the emissions calculations for the CO₂ concentration parameter
• The total operating hours in which a substitute data value was used in the emissions calculations for the stack gas flow rate parameter
• If moisture correction is required and a continuous moisture monitor is used, the total operating hours in which a substitute data value was used in the emissions calculations for the stack gas moisture content parameter
• An indication of the process units monitored by the CML
• For each EAF listed 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.

Subpart K Validation Report

The Validation Report assists you with determining the completeness and quality of your reported data.

We strongly encourage you to use the Validation Report to check your work. The Validation Report performs two types of checks:

• Data Completeness: Data required for reporting that are missing or incomplete.
• Data Quality: Data that are outside of the expected range of values.

Certain validation checks which are considered to represent critical errors must be corrected before you can successfully generate and submit your Annual Report. These checks are signified with a stop sign . If you feel that you have triggered one of these critical “stop signs” checks in error, or if there’s a reason why your report should be submitted despite the check being triggered, please submit a request to the e-GGRT Help Desk at GHGReporting@epa.gov.

You may view the Validation Report at any time.
