§98.331 Reporting threshold.
§98.333 Calculating GHG emissions.
§98.336 Data reporting requirements.
§98.338 Definitions.
You must report GHG emissions under this subpart if your facility contains a zinc production process and the facility meets the requirements of either §98.2(a)(1) or (2).
You must calculate and report the annual process CO2 emissions using the procedures specified in either paragraph (a) or (b) of this section.
(a) Calculate and report under this subpart the process or combined process and combustion CO2 emissions by operating and maintaining a CEMS according to the Tier 4 Calculation Methodology in §98.33(a)(4) and all associated requirements for Tier 4 in subpart C of this part (General Stationary Fuel Combustion Sources).
(b) Calculate and report under this subpart the process CO2 emissions by following paragraphs (b)(1) and (b)(2) of this section.
(1) For each Waelz kiln or electrothermic furnace at your facility used for zinc production, you must determine the mass of carbon in each carbon-containing material, other than fuel, that is fed, charged, or otherwise introduced into each Waelz kiln and electrothermic furnace at your facility for each year and calculate annual CO2 process emissions from each affected unit at your facility using Equation GG-1 of this section. For electrothermic furnaces, carbon containing input materials include carbon eletrodes and carbonaceous reducing agents. For Waelz kilns, carbon containing input materials include carbonaceous reducing agents. If you document that a specific material contributes less than 1 percent of the total carbon into the process, you do not have to include the material in your calculation using Equation R-1 of §98.183.
ECO2k = Annual CO2 process emissions from individual Waelz kiln or electrothermic furnace “k” (metric tons).
(Zinc)k = Annual mass of zinc bearing material charged to kiln or furnace ”k” (tons).
(CZinc)k = Carbon content of the zinc bearing material, from the annual carbon analysis for kiln or furnace “k” (percent by weight, expressed as a decimal fraction).
(Flux)k = Annual mass of flux materials (e.g., limestone, dolomite) charged to kiln or furnace “k” (tons).
(CFlux)k = Carbon content of the flux materials charged to kiln or furnace “k”, from the annual carbon analysis (percent by weight, expressed as a decimal fraction).
(Electrode)k = Annual mass of carbon electrode consumed in furnace “k” (tons).
(CElectrode)k = Carbon content of the carbon electrode consumed in furnace “k”, from the annual carbon analysis (percent by weight, expressed as a decimal fraction).
(Carbon)k = Annual mass of carbonaceous materials (e.g., coal, coke) charged to the kiln or furnace “k”(tons).
(CCarbon)k Carbon content of the carbonaceous materials charged to kiln or furnace, “k”, from the annual carbon analysis (percent by weight, expressed as a decimal fraction).
(2) You must determine the CO2 emissions from all of the Waelz kilns or electrothermic furnaces at your facility using Equation GG-2 of this section.
CO2 = Annual combined CO2 emissions from all Waelz kilns or electrothermic furnaces (tons).
ECO2k = Annual CO2 emissions from each Waelz kiln or electrothermic furnace k calculated using Equation GG-1 of this section (tons).
n = Total number of Waelz kilns or electrothermic furnaces at facility used for the zinc production.
(c) If GHG emissions from a Waelz kiln or electrothermic furnace are vented through the same stack as any combustion unit or process equipment that reports CO2 emissions using a CEMS that complies with the Tier 4 Calculation Methodology in subpart C of this part (General Stationary Fuel Combustion Sources), then the calculation methodology in paragraph (b) of this section shall not be used to calculate process emissions. The owner or operator shall report under this subpart the combined stack emissions according to the Tier 4 Calculation Methodology in §98.33(a)(4) and all associated requirements for Tier 4 in subpart C of this part.
[74 FR 56374, Oct. 30, 2009, as amended at 75 FR 66470, Oct. 28, 2010]
In addition to the information required by §98.3(c), each annual report must contain the information specified in paragraphs (a) or (b) of this section, as applicable, for each Waelz kiln or electrothermic furnace.
(a) If a CEMS is used to measure CO2 emissions, then you must report under this subpart the relevant information required for the Tier 4 Calculation Methodology in §98.36 and the information listed in this paragraph (a):
(1) Annual zinc product production capacity (tons).
(2) Annual production quantity for each zinc product (tons).
(3) Annual facility production quantity for each zinc product (tons).
(4) Number of Waelz kilns at each facility used for zinc production.
(5) Number of electrothermic furnaces at each facility used for zinc production.
(1) Identification number and annual process CO2 emissions from each individual Waelz kiln or electrothermic furnace (metric tons).
(2) Annual zinc product production capacity (tons).
(3) Annual production quantity for each zinc product (tons).
(8) Whether carbon content of each carbon-containing input material charged to each kiln or furnace is based on reports from the supplier or through self measurement using applicable ASTM standard method.
(9) If carbon content of each carbon-containing input material charged to each kiln or furnace is based on self measurement, the ASTM Standard Test Method used.
(11) Whether carbon content of the carbon electrode used in each furnace is based on reports from the supplier or through self measurement using applicable ASTM standard method.
(12) If carbon content of carbon electrode used in each furnace is based on self measurement, the ASTM standard method used.
(13) If you use the missing data procedures in §98.335(b), you must report how the monthly mass of carbon-containing materials with missing data was determined and the number of months the missing data procedures were used.
