(a) You must report GHG emissions under this subpart if you are an electric power system as defined in § 98.308 and your facility meets the requirements of § 98.2(a)(1). To calculate total annual GHG emissions for comparison to the 25,000 metric ton CO2e per year emission threshold in table A-3 to subpart A to this part, you must calculate emissions of each fluorinated GHG that is a component of a reportable insulating gas and then sum the emissions of each fluorinated GHG resulting from the use of electrical transmission and distribution equipment for threshold applicability purposes using equation DD-1 to this section.
Where:
E = Annual emissions for threshold applicability purposes (metric tons CO2e).
NCEPS,j = the total nameplate capacity of equipment containing reportable insulating gas j (excluding hermetically sealed-pressure equipment) located within the facility plus the total nameplate capacity of equipment containing reportable insulting gas j (excluding hermetically sealed-pressure equipment) that is not located within the facility but is under common ownership or control (lbs).
GHGi,w = The weight fraction of fluorinated GHG i in reportable insulating gas j in the gas insulated equipment included in the total nameplate capacity NCEPS,j, expressed as a decimal fraction. If fluorinated GHG i is not part of a gas mixture, use a value of 1.0.
GWPi = Gas-appropriate GWP as provided in table A-1 to subpart A of this part.
EF = Emission factor for electrical transmission and distribution equipment (lbs emitted/lbs nameplate capacity). For all gases, use an emission factor or 0.1.
i = Fluorinated GHG contained in the electrical transmission and distribution equipment.
0.000453592 = Conversion factor from lbs to metric tons.
(b) A facility other than an electric power system that is subject to this part because of emissions from any other source category listed in table A-3 or A-4 to subpart A of this part is not required to report emissions under subpart DD of this part unless the total estimated emissions of fluorinated GHGs that are components of reportable insulating gases, as calculated in equation DD-2 to this section, equals or exceeds 25,000 tons CO2e.
Where:
E = Annual emissions for threshold applicability purposes (metric tons CO2e).
NCother,j = For a facility other than an electric power system, the total nameplate capacity of equipment containing reportable insulating gas j (excluding hermetically sealed-pressure equipment) located within the facility (lbs).
GHGi,w = The weight fraction of fluorinated GHG i in reportable insulating gas j in the gas insulated equipment included in the total nameplate capacity NCother,j, expressed as a decimal fraction. If fluorinated GHG i is not part of a gas mixture, use a value of 1.0.
GWPi = Gas-appropriate GWP as provided in table A-1 to subpart A of this part.
EF = Emission factor for electrical transmission and distribution equipment (lbs emitted/lbs nameplate capacity). For all gases, use an emission factor or 0.1.
i = Fluorinated GHG contained in the electrical transmission and distribution equipment.
0.000453592 = Conversion factor from lbs to metric tons.
