Calculation of CO2 Emissions. The operator shall calculate emissions of CO2 as specified below.
The operator of a crude oil or natural gas production facility identified with the NAICS code 211111 shall report CO2 emissions from stationary combustion according to the methods specified in sections 95125(c),(d), and(f).
For natural gas and associated gas, the operator shall use the method specified in section 95125(c) or 95125(d).
For low Btu gases, the operator shall report emissions resulting from the combustion and/or destruction of low Btu gases as specified in section 95113(d)(3) or section 95125(f), as applicable.
For fuel mixtures, the operator shall apply the method specified in section 95125(f).
For all other facilities, the operator shall measure and report CO2 emissions from stationary combustion using one of the following methods:
Use of a continuous emissions monitoring systems (CEMS) as specified in section 95125(g);
Use of default emission factors and high heat values as specified in section 95125(a).
Where a default high heat value is not supplied for a specific fuel type in Appendix A, the operator shall use the method provided in section 95125(c), (d), or (h) to calculate CO2 emissions.
Operators not using CEMS who co-fire two or more types of fuels shall select methods specified in sections 95115(b)(1)-(2) that enable the operator to separately report CO2 emissions for each fuel type. Operators who co-fire with waste-derived fuels that are partly but not pure biomass may elect to determine the biomass portion of total CO2 emissions resulting from the combustion of the co-fired fuels using the method specified in section 95125(h)(2).
Calculation of N2O and CH4 Emissions. The operator shall calculate emissions of N2O and CH4 emissions from stationary combustion using the methodologies provided in section 95125(b).
Electricity Generating Units. Operators of general stationary combustion facilities with electricity generating units subject to the requirements of this article shall meet the requirements of section 95111.
Cogeneration. Operators of general stationary combustion facilities with cogeneration systems subject to the requirements of this article shall meet the requirements of section 95112.
