PART 75--CONTINUOUS EMISSION MONITORING--Table of Contents
 
                    Subpart B--Monitoring Provisions
 
Sec. 75.13  Specific provisions for monitoring CO2 emissions.

    (a) CO2 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 Sec. 75.10 for a CO2 continuous emission 
monitoring system and flow monitoring system for each affected unit. The 
owner or operator shall comply with the applicable provisions specified 
in Secs. 75.11(a) through (e) or Sec. 75.16, except that the phrase 
``CO2 continuous emission monitoring system'' shall apply 
rather than ``SO2 continuous emission monitoring system,'' 
the phrase ``CO2 concentration'' shall apply rather than 
``SO2 concentration,'' the term ``maximum potential 
concentration of CO2'' shall apply rather than ``maximum 
potential concentration of SO2,'' and the phrase 
``CO2 mass emissions'' shall apply rather than 
``SO2 mass emissions.''
    (b) Determination of CO2 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 CO2 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 CO2, 
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 CO2 
mass emissions (in tons) in accordance with the procedures in appendix G 
to this part.
    (c) Determination of CO2 mass emissions using an O2 
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 CO2 concentration and mass emissions with a 
flow monitoring system; a continuous O2 concentration 
monitor; fuel F and Fc factors; and, where O2 
concentration is measured on a dry basis (or where Equation F-14b in 
appendix F to this part is used to determine CO2 
concentration), either, a continuous moisture monitoring system, as 
specified in Sec. 75.11(b)(2), or a fuel-specific default moisture 
percentage (if applicable), as defined in Sec. 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 Sec. 75.16, except that the phrase 
``CO2 continuous emission monitoring system'' shall apply 
rather than ``SO2 continuous emission monitoring system,'' 
the term ``maximum potential concentration of CO2'' shall 
apply rather than ``maximum potential concentration of SO2,'' 
and the phrase ``CO2 mass emissions'' shall apply rather than 
``SO2 mass emissions.''
    (d) Determination of CO2 mass emissions from low mass 
emissions units. The owner or operator of a unit that qualifies as a low 
mass emissions unit under Sec. 75.19(a) and (b) shall comply with one of 
the following:

[[Page 220]]

    (1) Meet the general operating requirements in Sec. 75.10 for a 
CO2 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 Sec. 75.19(c) 
for estimating hourly CO2 mass emissions, if applicable under 
Sec. 75.19(a) and (b).
