Facility Level Information

For each process unit at your facility, report the following required information:

• Annual zinc production capacity
• Number of Waelz kilns used for zinc production
• Number of electrothermic furnaces used for zinc production
• For each zinc product produced (make sure the box is checked next to each Zinc Product).
  
  • Zinc Product Name
  • Annual Production of the Product

Kiln and Furnace Information For Units Not Monitored by CEMS

For each process unit NOT monitored by a CEMS, report the following required information:

• A unique name or identifier for the kiln or furnace, plus optional description for this unit (see also About Unique Unit Names)
• Type of Kiln or Furnace (selecting from the pick list)
• For each Carbon-containing Input Material:
  • Input Material Name
  • Number of months missing data procedures were followed to determine the monthly mass of the material (selecting from the pick list)
  • Number of months missing data procedures were followed to repeat the test to determine the carbon content (selecting from the pick list)
  • Procedure used to develop substitute data for the monthly mass of the carbon-containing input material
  • Test method used for the carbon content analysis (selecting from the pick list)

Kiln and Furnace Information for Units Monitored by CEMS

• A unique name or identifier for the kiln or furnace, plus optional description for this unit (see also About Unique Unit Names)
• Type of Kiln or Furnace (selecting from the pick list)
• Optional comment clarifying the operating characteristics or limitations of the CEMs data

Emissions Information for Units Not Monitored by CEMS

For each kiln or furnace not monitored by CEMS, report the following required information calculated by the IVT module:

• Annual CO₂ process emissions from Waelz Kiln or Electrothermic furnace (metric tons) 

Emissions Information for Units Monitored by CEMS

For each CEMS Monitoring Location, provide the following information:

• 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 types of fuel combusted in the unit(s) monitored by the CEMS
• The Tier 4/CEMS methodology start and end dates
• The total 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)(This is the sum of the four quarterly totals)
• An indication 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
• The total annual CO2 emissions from the CEMS Monitoring Location (CML) Summary attributable to combustion (metric tons)

Do not leave any of these fields blank. If, for example, your facility has no biogenic CO₂ emissions, enter '0'.

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.
