Code of Federal Regulations Title 40. Protection of Environment § 40.98.213 Calculating GHG emissions

(a) Calculate the process emissions of CO₂ using calcination fractions with Equation U–1 of this section.

Where:

E_CO2 = Annual CO₂ mass emissions from consumption of carbonates (metric tons).

M_i = Annual mass of carbonate type i consumed (tons).

EF_i = Emission factor for the carbonate type i, as specified in Table U–1 to this subpart, metric tons CO₂/metric ton carbonate consumed.

F_i = Fraction calcination achieved for each particular carbonate type i (decimal fraction). As an alternative to measuring the calcination fraction, a value of 1.0 can be used.

n = Number of carbonate types.

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

(b) Calculate the process emissions of CO₂ using actual mass of output carbonates with Equation U–2 of this section.

Where:

E_CO2 = Annual CO₂ mass emissions from consumption of carbonates (metric tons).

M_k = Annual mass of input carbonate type k (tons).

EF_k = Emission factor for the carbonate type k, as specified in Table U–1 of this subpart (metric tons CO₂/metric ton carbonate input).

M_j = Annual mass of output carbonate type j (tons).

EF_j = Emission factor for the output carbonate type j, as specified in Table U–1 of this subpart (metric tons CO₂ /metric ton carbonate input).

m = Number of input carbonate types.

n = Number of output carbonate types.
