§98.211 Reporting threshold.
§98.212 GHGs to report.
§98.213 Calculating GHG emissions.
§98.214 Monitoring and QA/QC requirements.
§98.216 Data reporting requirements.
§98.217 Records that must be retained.
§98.218 Definitions.
You must report GHG emissions from miscellaneous uses of carbonate if your facility uses carbonates as defined in §98.210 of this subpart and the facility meets the requirements of either §98.2(a)(1) or (a)(2).
You must report CO2 process emissions from all miscellaneous carbonate use at your facility as specified in this subpart.
(a) Calculate the process emissions of CO2 using calcination fractions with Equation U-1 of this section.
(a) The annual mass of carbonate consumed (for Equation U-1 of this subpart) or carbonate inputs (for Equation U-2 of this subpart) must be determined annually from monthly measurements using the same plant instruments used for accounting purposes including purchase records or direct measurement, such as weigh hoppers or weigh belt feeders.
(b) The annual mass of carbonate outputs (for Equation U-2 of this subpart) must be determined annually from monthly measurements using the same plant instruments used for accounting purposes including purchase records or direct measurement, such as weigh hoppers or belt weigh feeders.
(c) If you follow the procedures of §98.213(a), as an alternative to assuming a calcination fraction of 1.0, you can determine on an annual basis the calcination fraction for each carbonate consumed based on sampling and chemical analysis using a suitable method such as using an x-ray fluorescence standard method or other enhanced industry consensus standard method published by an industry consensus standard organization (e.g., ASTM, ASME, etc.).
In addition to the information required by §98.3(c), each annual report must contain the information specified in paragraphs (a) through (g) of this section at the facility level, as applicable.
(a) Annual CO2 emissions from miscellaneous carbonate use (metric tons).
(c) Measurement method used to determine the mass of carbonate.
(d) Method used to calculate emissions.
(e) If you followed the calculation method of §98.213(a), you must report the information in paragraphs (e)(1) through (3) of this section.
(3) If you determined the calcination fraction, indicate which standard method was used.
(g) Number of times in the reporting year that missing data procedures were followed to measure carbonate consumption, carbonate input or carbonate output (months).

In addition to the records required by §98.3(g), you must retain the records specified in paragraphs (a) through (e) of this section:
(a) Monthly carbonate consumption (by carbonate type in tons).
(b) You must document the procedures used to ensure the accuracy of the monthly measurements of carbonate consumption, carbonate input or carbonate output including, but not limited to, calibration of weighing equipment and other measurement devices.
(c) Records of all analyses conducted to meet the requirements of this rule.
(d) Records of all calculations conducted.
(e) Verification software records. You must keep a record of the file generated by the verification software specified in §98.5(b) for the applicable data specified in paragraphs (e)(1) through (4) of this section. Retention of this file satisfies the recordkeeping requirement for the data in paragraphs (e)(1) through (4) of this section.
(1) Fraction calcination achieved for each particular carbonate type. As an alternative to measuring the calcination fraction, a value of 1.0 can be used (decimal fraction) (Equation U-1 of §98.213).
(2) Annual mass of each carbonate type consumed (tons) (Equation U-1).
(3) Annual mass of each input carbonate type (tons) (Equation U-2 of §98.213).
(4) Annual mass of each output carbonate type (tons) (Equation U-2).
