Code of Federal Regulations Title 40. Protection of Environment § 40.98.143 Calculating GHG emissions

(i) For each carbonate-based raw material charged to the furnace, obtain from the supplier of the raw material the carbonate-based mineral mass fraction.

(ii) Determine the quantity of each carbonate-based raw material charged to the furnace.

(iii) Apply the appropriate emission factor for each carbonate-based raw material charged to the furnace, as shown in Table N–1 to this subpart.

(iv) Use Equation N–1 of this section to calculate process mass emissions of CO₂ for each furnace:

Where:

E_CO2 = Process emissions of CO₂ from the furnace (metric tons).

n = Number of carbonate-based raw materials charged to furnace.

MF_i = Annual average decimal mass fraction of carbonate-based mineral i in carbonate-based raw material i.

M_i = Annual amount of carbonate-based raw material i charged to furnace (tons).

2000/2205 = Conversion factor to convert tons to metric tons.

EF_i = Emission factor for carbonate-based raw material i (metric ton CO₂ per metric ton carbonate-based raw material as shown in Table N–1 to this subpart).

F_i = Decimal fraction of calcination achieved for carbonate-based raw material i, assumed to be equal to 1.0.

(v) You must calculate the total process CO₂ emissions from continuous glass melting furnaces at the facility using Equation N–2 of this section:

Where:

CO₂ = Annual process CO₂ emissions from glass manufacturing facility (metric tons).

E_CO2i = Annual CO₂ emissions from glass melting furnace i (metric tons).

k = Number of continuous glass melting furnaces.

(vi) Calculate and report under subpart C of this part (General Stationary Fuel Combustion Sources) the combustion CO₂ emissions in the glass furnace according to the applicable requirements in subpart C.
