Specific provisions for monitoring CO 2 emissions.

(a) CO 2 continuous emission monitoring system. If the owner or operator chooses to use the continuous emission monitoring method, then the owner or operator shall meet the general operating requirements in § 75.10 for a CO 2 continuous emission monitoring system and flow monitoring system for each affected unit. The owner or operator shall comply with the applicable provisions specified in §§ 75.11(a) through (e) or § 75.16, except that the phrase “CO 2 continuous emission monitoring system” shall apply rather than “SO 2 continuous emission monitoring system,” the phrase “CO 2 concentration” shall apply rather than “SO 2 concentration,” the term “maximum potential concentration of CO 2 ” shall apply rather than “maximum potential concentration of SO 2 ,” and the phrase “CO 2 mass emissions” shall apply rather than “SO 2 mass emissions.” (b) Determination of CO 2 emissions using appendix G to this part. If the owner or operator chooses to use the appendix G method, then the owner or operator shall follow the procedures in appendix G to this part for estimating daily CO 2 mass emissions based on the measured carbon content of the fuel and the amount of fuel combusted. For units with wet flue gas desulfurization systems or other add-on emissions controls generating CO 2 , the owner or operator shall use the procedures in appendix G to this part to estimate both combustion-related emissions based on the measured carbon content of the fuel and the amount of fuel combusted and sorbent-related emissions based on the amount of sorbent injected. The owner or operator shall calculate daily, quarterly, and annual CO 2 mass emissions (in tons) in accordance with the procedures in appendix G to this part. (c) Determination of CO 2 mass emissions using an O 2 monitor according to appendix F to this part. If the owner or operator chooses to use the appendix F method, then the owner or operator shall determine hourly CO 2 concentration and mass emissions with a flow monitoring system; a continuous O 2 concentration monitor; fuel F and F c factors; and, where O 2 concentration is measured on a dry basis (or where Equation F-14b in appendix F to this part is used to determine CO 2 concentration), either, a continuous moisture monitoring system, as specified in § 75.11(b)(2), or a fuel-specific default moisture percentage (if applicable), as defined in § 75.11(b)(1); and by using the methods and procedures specified in appendix F to this part. For units using a common stack, multiple stack, or bypass stack, the owner or operator may use the provisions of § 75.16, except that the phrase “CO 2 continuous emission monitoring system” shall apply rather than “SO 2 continuous emission monitoring system,” the term “maximum potential concentration of CO 2 ” shall apply rather than “maximum potential concentration of SO 2 ,” and the phrase “CO 2 mass emissions” shall apply rather than “SO 2 mass emissions.” (d) Determination of CO 2 mass emissions from low mass emissions units. The owner or operator of a unit that qualifies as a low mass emissions unit under § 75.19(a) and (b) shall comply with one of the following: (1) Meet the general operating requirements in § 75.10 for a CO 2 continuous emission monitoring system and flow monitoring system; (2) Meet the requirements specified in paragraph (b) or (c) of this section for use of the methods in appendix G or F to this part, respectively; or (3) Use the low mass emissions excepted methodology in § 75.19(c) for estimating hourly CO 2 mass emissions, if applicable under § 75.19(a) and (b). If this option is selected for CO 2 , the LME methodology must also be used for NO X and SO 2 when these parameters are required to be monitored by applicable program(s).
