§ 98.293 Calculating GHG emissions.
(a) For each soda ash manufacturing line that meets the conditions specified in § 98.33(b)(4)(ii) or (b)(4)(iii), you must calculate and report under this subpart the combined process and combustion CO2 emissions by operating and maintaining a CEMS to measure CO2 emissions according to the Tier 4 Calculation Methodology specified in § 98.33(a)(4) and all associated requirements for Tier 4 in subpart C of this part (General Stationary Fuel Combustion Sources).
(1) Calculate and report under this subpart the combined process and combustion CO2 emissions by operating and maintaining a CEMS to measure CO2 emissions according to the Tier 4 Calculation Methodology specified in § 98.33(a)(4) and all associated requirements for Tier 4 in subpart C of this part (General Stationary Fuel Combustion Sources).
(3)Site-specific emission factor method. Use Equations CC-3, CC-4, and CC-5 of this section to determine annual CO2 process emissions from manufacturing lines that use the liquid alkaline feedstock process to produce soda ash. You must conduct an annual performance test and measure CO2 emissions and flow rates at all process vents from the mine water stripper/evaporator for each manufacturing line and calculate CO2 emissions as described in paragraphs (b)(3)(i) through (b)(3)(iv) of this section.
CCO2 = Hourly CO2 concentration (percent CO2) as determined by § 98.294(c).
