You must calculate and report the annual process CO2 emissions from each kiln using the procedure in paragraphs (a) and (b) of this section.
(a)
For each cement kiln 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).
(b)
For each kiln that is not subject to the requirements in paragraph (a) of this section, calculate and report the process and combustion CO2 emissions from the kiln by using the procedure in either paragraph (c) or (d) of this section.
(c)
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).
(d)
Calculate and report process and combustion CO2 emissions separately using the procedures specified in paragraphs (d)(1) through (d)(4) of this section.

emissions from clinker production. Calculate CO2 emissions from each kiln using Equations H-2 through H-5 of this section.
(i) Kiln-Specific Clinker Emission Factor.
(A)
Calculate the kiln-specific clinker emission factor using Equation H-3 of this section.
(B)
Non-calcined CaO is CaO that remains in the clinker in the form of CaCO3 and CaO in the clinker that entered the kiln as a non-carbonate species. Non-calcined MgO is MgO that remains in the clinker in the form of MgCO3 and MgO in the clinker that entered the kiln as a non-carbonate species.
(ii) Kiln-Specific CKD Emission Factor.
(A)
Calculate the kiln-specific CKD emission factor for CKD not recycled to the kiln using Equation H-4 of this section.
(B)
Non-calcined CaO is CaO that remains in the CKD in the form of CaCO3 and CaO in the CKD that entered the kiln as a non-carbonate species. Non-calcined MgO is MgO that remains in the CKD in the form of MgCO3 and MgO in the CKD that entered the kiln as a non-carbonate species.

emissions from raw materials. Calculate CO2 emissions from raw materials using Equation H-5 of this section:
(4)
Calculate and report under subpart C of this part (General Stationary Fuel Combustion Sources) the combustion CO2 emissions from the kiln according to the applicable requirements in subpart C.
