§98.51 Reporting threshold.
§98.52 GHGs to report.
§98.53 Calculating GHG emissions.
§98.57 Records that must be retained.
§98.58 Definitions.
You must report GHG emissions under this subpart if your facility contains an adipic acid production process and the facility meets the requirements of either §98.2(a)(1) or (2).
(a) You must report N2O process emissions at the facility level.
(b) You must report under subpart C of this part (General Stationary Fuel Combustion Sources) the emissions of CO2, CH4, and N2O from each stationary combustion unit following the requirements of subpart C.
(iii) Otherwise, you must submit the request within 45 days following promulgation of this subpart or within the first 30 days of each subsequent reporting year.
(1) You must conduct the test on the vent stream from the nitric acid oxidation step of the process, referred to as the test point, according to the methods specified in §98.54(b) through (f). If multiple adipic acid production units exhaust to a common abatement technology and/or emission point, you must sample each process in the ducts before the emissions are combined, sample each process when only one process is operating, or sample the combined emissions when multiple processes are operating and base the site-specific emission factor on the combined production rate of the multiple adipic acid production units.
EFN2O,z = Average facility-specific N2O emission factor for each adipic acid production unit “z” (lb N2O/ton adipic acid produced).
CN2O = N2O concentration per test run during the performance test (ppm N2O).
(e) If the adipic acid production unit exhausts to any N2O abatement technology “N”, you must determine the annual amount of adipic acid produced while N2O abatement technology “N” is operating according to §98.54(f). Then you must calculate the abatement factor for N2O abatement technology “N” according to Equation E-2 of this section.
(f) You must determine the annual amount of adipic acid produced according to §98.54(f).
EFN2Oz = N2O emissions factor for unit “z” (lb N2O/ton adipic acid produced).
EFN2O,z = N2O emissions factor for unit “z” (lb N2O/ton adipic acid produced).
EFN2O = N2O emissions factor for unit “z” (lb N2O/ton adipic acid produced).

In addition to the information required by §98.3(g), you must retain the records specified in paragraphs (a) through (i) of this section at the facility level:
(a) Annual adipic acid production capacity (tons).
(b) Records of significant changes to process.
(c) Number of facility and unit operating hours in calendar year.
(d) Documentation of how accounting procedures were used to estimate production rate.
(e) Documentation of how process knowledge was used to estimate abatement technology destruction efficiency.
(f) Performance test reports.
(g) Measurements, records and calculations used to determine reported parameters.
(h) Documentation of the procedures used to ensure the accuracy of the measurements of all reported parameters, including but not limited to, calibration of weighing equipment, flow meters, and other measurement devices. The estimated accuracy of measurements made with these devices must also be recorded, and the technical basis for these estimates must be provided.
(i) 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 (i)(1) through (3) of this section. Retention of this file satisfies the recordkeeping requirement for the data in paragraphs (i)(1) through (3) of this section.
(1) Annual adipic acid production from each adipic acid production unit (tons) (Equations E-2, E-3a, E-3b, E-3c, and E-3d of §98.53).
(2) Production rate per test run during the performance test for each production unit test run (tons adipic acid produced/hr) (Equation E-1 of §98.53).
(3) Annual adipic acid production per N2O abatement technology during which N2O abatement technology was used (tons adipic acid produced) (Equation E-2).
