You must calculate and report the annual process CO2 emissions from each smelting furnace using the procedure in paragraphs (a) and (b) of this section.
Where:
ECO2 = Annual process CO2 emissions from an individual smelting furnace (metric tons).
44/12 = Ratio of molecular weights, CO2 to carbon.
2000/2205 = Conversion factor to convert tons to metric tons.
Ore = Annual mass of lead ore charged to the smelting furnace (tons).
COre = Carbon content of the lead ore, from the carbon analysis results (percent by weight, expressed as a decimal fraction).
Scrap = Annual mass of lead scrap charged to the smelting furnace (tons).
CScrap = Carbon content of the lead scrap, from the carbon analysis (percent by weight, expressed as a decimal fraction).
Flux = Annual mass of flux materials (e.g., limestone, dolomite) charged to the smelting furnace (tons).
CFlux = Carbon content of the flux materials, from the carbon analysis (percent by weight, expressed as a decimal fraction).
Carbon = Annual mass of carbonaceous materials (e.g., coal, coke) charged to the smelting furnace (tons).
CCarbon = Carbon content of the carbonaceous materials, from the carbon analysis (percent by weight, expressed as a decimal fraction).
Other = Annual mass of any other material containing carbon, other than fuel, fed, charged, or otherwise introduced into the smelting furnace (tons).
COther = Carbon content of the other material from the carbon analysis results (percent by weight, expressed as a decimal fraction).
Where:
CO2 = Annual process CO2 emissions from smelting furnaces at facility used for lead production (metric tons).
ECO2k = Annual process CO2 emissions from smelting furnace k calculated using Equation R-1 of this section (metric tons/year).
k = Total number of smelting furnaces at facility used for lead production.
