# §98.86. Data reporting requirements.


In addition to the information required by [§ 98.3(c)](/cfr/40/98.3.md?p=c), each annual report must contain the information specified in paragraphs [(a)](#a) and [(b)](#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)](/cfr/40/98.36.md?p=e-2-vi) and the information listed in this [paragraph(a)](#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)](#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).**
