In addition to the information required by § 98.3(c), each annual report must contain the information specified in paragraphs (a) and (b) of this section, as appropriate.
- (a)If a CEMS is used to measure CO2 emissions, then you must report under this subpart the relevant information required by § 98.36(e)(2)(vi) and the information listed in this paragraph(a):
- (1)Monthly clinker production from each kiln at the facility.
- (2)Annual facility cement production.
- (3)Number of kilns and number of operating kilns.
- (4)Annual arithmetic average of total CaO content of clinker at the facility, wt-fraction.
- (5)Annual arithmetic average of non-calcined CaO content of clinker at the facility, wt-fraction.
- (6)Annual arithmetic average of total MgO content of clinker at the facility, wt-fraction.
- (7)Annual arithmetic average of non-calcined MgO content of clinker at the facility, wt-fraction.
- (8)Annual facility CKD not recycled to the kiln(s), tons.
- (b)If a CEMS is not used to measure CO2 emissions, then you must report the information listed in this paragraph (b) for each kiln:
- (1)Kiln identification number.
- (2)[Reserved]
- (3)Annual cement production at the facility.
- (4)Number of kilns and number of operating kilns.
- (5)-(6) [Reserved]
- (7)Method used to determine non-calcined CaO and non-calcined MgO in clinker.
- (8)[Reserved]
- (9)Method used to determine non-calcined CaO and non-calcined MgO in CKD.
- (10)[Reserved]
- (11)Quarterly kiln-specific CKD CO2 emission factors for each kiln (metric tons CO2/metric ton CKD produced).
- (12)[Reserved]
- (13)Name of raw kiln feed or raw material.
- (14)Number of times missing data procedures were used to determine the following information:
- (i)Clinker production (number of months).
- (ii)Carbonate contents of clinker (number of months).
- (iii)Non-calcined content of clinker (number of months).
- (iv)CKD not recycled to kiln (number of quarters).
- (v)Non-calcined content of CKD (number of quarters)
- (vi)Organic carbon contents of raw materials (number of times).
- (vii)Raw material consumption (number of months).
- (15)Method used to determine the monthly clinker production from each kiln.
- (16)Annual clinker production (metric tons).
- (17)Annual average clinker CO2 emission factor for the facility, averaged across all kilns (metric tons CO2/metric ton clinker produced).
- (18)Annual average CKD CO2 emission factor for the facility, averaged across all kilns (metric tons CO2/metric ton CKD produced).
- (19)Annual arithmetic average of total CaO content of clinker at the facility, wt-fraction.
- (20)Annual arithmetic average of non-calcined CaO content of clinker at the facility, wt-fraction.
- (21)Annual arithmetic average of total MgO content of clinker at the facility, wt-fraction.
- (22)Annual arithmetic average of non-calcined MgO content of clinker at the facility, wt-fraction.
- (23)Annual arithmetic average of total CaO content of CKD not recycled to the kiln(s) at the facility, wt-fraction.
- (24)Annual arithmetic average of non-calcined CaO content of CKD not recycled to the kiln(s) at the facility, wt-fraction.
- (25)Annual arithmetic average of total MgO content of CKD not recycled to the kiln(s) at the facility, wt-fraction.
- (26)Annual arithmetic average of non-calcined MgO content of CKD not recycled to the kiln(s) at the facility, wt-fraction.
- (27)Annual facility CKD not recycled to the kiln(s), tons.
- (28)The amount of raw kiln feed consumed annually at the facility, tons (dry basis).
