Calculating GHG emissions.

§ 98.393 Calculating GHG emissions.

(a) Calculation for individual products produced, imported, or exported. (1) Except as provided in paragraphs (h) and (i) of this section, any refiner, importer, or exporter shall calculate CO2 emissions from each individual petroleum product and natural gas liquid using Equation MM–1 of this section.

Where:

CO2i = Annual CO2 emissions that would result from the complete combustion or oxidation of each petroleum product or natural gas liquid “i” (metric tons). Producti = Annual volume of product “i” produced, imported, or exported by the reporting party (barrels). For refiners, this volume only includes products ex refinery gate, and excludes products that entered the refinery but are not reported under § 98.396(a)(2). For natural gas liquids, volumes shall reflect the individual components of the product as listed in Table MM–1 to subpart MM. EFi = Product-specific CO2 emission factor (metric tons CO2 per barrel).

(2) In the event that an individual petroleum product is produced as a solid rather than liquid any refiner, importer, or exporter shall calculate CO2 emissions using Equation MM–1 of this section.

Where:

CO2i = Annual CO2 emissions that would result from the complete combustion or oxidation of each petroleum product “i” (metric tons). Producti = Annual mass of product “i” produced, imported, or exported by the reporting party (metric tons). For refiners, this mass only includes products ex refinery gate, and excludes products that entered the refinery but are not reported under § 98.396(a)(2). EFi = Product-specific CO2 emission factor (metric tons CO2 per metric ton of product).

(b) Calculation for individual products that enter a refinery as a non-crude feedstock. (1) Except as provided in paragraphs (h) and (i) of this section, any refiner shall calculate CO2 emissions from each non-crude feedstock using Equation MM–2 of this section.

Where:

CO2j = Annual CO2 emissions that would result from the complete combustion or oxidation of each non-crude feedstock “j” (metric tons). Feedstockj = Annual volume of a petroleum product or natural gas liquid “j” that enters the refinery to be further refined or otherwise used on site (barrels). For natural gas liquids, volumes shall reflect the individual components of the product as listed in table MM–1 of this subpart. EFj = Feedstock-specific CO2 emission factor (metric tons CO2 per barrel).

(2) In the event that a non-crude feedstock enters a refinery as a solid rather than liquid, the refiner shall calculate CO2 emissions using Equation MM–2 of this section.

Where:

CO2j = Annual CO2 emissions that would result from the complete combustion or oxidation of each non-crude feedstock “j” (metric tons). Feedstockj = Annual mass of a petroleum product “j” that enters the refinery to be further refined or otherwise used on site (metric tons). EFj = Feedstock-specific CO2 emission factor (metric tons CO2 per metric ton of feedstock).

(c) Calculation for biomass co-processed with petroleum feedstocks. (1) Refiners shall calculate CO2 emissions from each type of biomass that enters a refinery and is co-processed with petroleum feedstocks using Equation MM–3 of this section.

Where:

CO2m = Annual CO2 emissions that would result from the complete combustion or oxidation of each type of biomass “m” (metric tons). Biomassm = Annual volume of a specific type of biomass that enters the refinery and is co-processed with petroleum feedstocks to produce a petroleum product reported under paragraph (a) of this section (barrels). EFm = Biomass-specific CO2 emission factor (metric tons CO2 per barrel).
