# 98.242 GHGs to report.

You must report the information in paragraphs (a) through (c) of this section:

(a) CO<sub>2</sub> CH<sub>4</sub>, and N<sub>2</sub>O process emissions from each petrochemical process unit. Process emissions include CO<sub>2</sub> 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<sub>2</sub>, CH<sub>4</sub>, and N<sub>2</sub>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<sub>2</sub> 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<sub>2</sub> emissions for each petrochemical process unit.

(b) CO<sub>2</sub>, CH<sub>4</sub>, and N<sub>2</sub>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<sub>2</sub>, CH<sub>4</sub>, and N<sub>2</sub>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<sub>2</sub> captured. You must report the mass of CO<sub>2</sub> captured under, subpart PP of this part (Suppliers of Carbon Dioxide (CO<sub>2</sub>) by following the requirements of subpart PP.
