Fleet average cold temperature NMHC exhaust emissions (grams/mile) = [SIGMA](N * FEL) ÷ Total number of vehicles sold of the applicable weight category (i.e., either LDV + LLDTs, or HLDT + MDPVs)
Where:
N = The number of LDVs and LLDTs, or HLDTs and MDPVs, sold within the applicable FEL, based on vehicles counted to the point of first sale.
FEL = Family Emission Limit (grams/mile).
NMHC Credits or Debits = (Cold Temperature NMHC Standard-Manufacturer's Sales-Weighted Fleet Average Cold Temperature NMHC Emissions) * (Total Number of Vehicles Sold)
Where:
Cold Temperature NMHC Standard = 0.3 grams/mile for LDV/LLDTs or 0.5 grams/mile for HLDT/MDPV, per § 86.1811-10(g)(2) .
Manufacturer's Sales-Weighted Fleet Average Cold Temperature NMHC Emissions = average calculated according to paragraph (m) of this section.
Total Number of Vehicles Sold = Total 50-State sales based on the point of first sale.
