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) you where you need to enter information:

• #Subpart Subpart K Summary Information for this Facility#Subpart

Subpart K Summary Information for this Facility

Subpart K Furnace Informationanchor

The required electric arc furnace (EAF) information and the forms associated with required EAF information is 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 Anchor

The required emissions information, and the manner by which required emissions information it is entered into e-GGRT, is different for 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 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.

For each CEMS Monitoring LocationWhere 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.
