GHGs to report.

You must report the information in paragraphs (a) through (c) of this section: (a) CO 2 CH 4 , and N 2 O process emissions from each petrochemical process unit. Process emissions include CO 2 generated by reaction in the process and by combustion of process off-gas in stationary combustion units and flares. (1) If you comply with § 98.243(b) or (d), report under this subpart the calculated CO 2 , CH 4 , and N 2 O emissions for each stationary combustion source and flare that burns any amount of petrochemical process off-gas. If you comply with § 98.243(b), also report under this subpart the measured CO 2 emissions from process vents routed to stacks that are not associated with stationary combustion units. (2) If you comply with § 98.243(c), report under this subpart the calculated CO 2 emissions for each petrochemical process unit. (b) CO 2 , CH 4 , and N 2 O combustion emissions from stationary combustion units. (1) If you comply with § 98.243(b) or (d), report these emissions from stationary combustion units that are associated with petrochemical process units and burn only supplemental fuel under subpart C of this part (General Stationary Fuel Combustion Sources) by following the requirements of subpart C. (2) If you comply with § 98.243(c), report CO 2 , CH 4 , and N 2 O combustion emissions under subpart C of this part (General Stationary Fuel Combustion Sources) by following the requirements of subpart C for all fuels, except emissions from burning petrochemical process off-gas in any combustion unit, including units that are not part of the petrochemical process unit, are not to be reported under subpart C of this part. Determine the applicable Tier in subpart C of this part (General Stationary Fuel Combustion Sources) based on the maximum rated heat input capacity of the stationary combustion source. (c) CO 2 captured. You must report the mass of CO 2 captured under, subpart PP of this part (Suppliers of Carbon Dioxide (CO 2 ) by following the requirements of subpart PP.
