(a) The total mass of each fluorinated GHG imported and exported inside equipment or foams must be estimated using Equation QQ-1 of this section:[GRAPHIC] [TIFF OMITTED] TR01DE10.054 where: I = Total mass of the fluorinated GHG imported or exported annually
(metric tons).t = Equipment/foam type containing the fluorinated GHG.St = Mass of fluorinated GHG per unit of equipment type t or
foam type t (charge per piece of equipment, kg) or density of
fluorinated GHG in foam (charge per cubic foot of foam, kg per
cubic foot).Nt = Number of units of equipment type t or foam type t
imported or exported annually (pieces of equipment or cubic
feet of foam).0.001 = Factor converting kg to metric tons.
(b) When the identity and mass of fluorinated GHGs in a closed-cell foam is unknown to the importer or exporter, the total mass in CO2e for the fluorinated GHGs imported and exported inside closed-cell foams must be estimated using Equation QQ-2 of this section:[GRAPHIC] [TIFF OMITTED] TR01DE10.055 where: I = Total mass in CO2e of the fluorinated GHGs imported or
exported in close-cell foams annually (metric tons).t = Equipment/foam type containing the fluorinated GHG.St = Mass in CO2e of the fluorinated GHGs per unit
of equipment type t or foam type t (charge per piece of
equipment, kg) or density of fluorinated GHG in foam
(CO2e per cubic foot of foam, kg CO2e
per cubic foot).Nt = Number of units of equipment type t or foam type t
imported or exported annually (pieces of equipment or cubic
feet of foam).0.001 = Factor converting kg to metric tons. [74 FR 56374, Oct. 30, 2009, as amended at 78 FR 71978, Nov. 29, 2013]
