[p. 6734, Table IV.B-2a: Final Tier 2 Light-Duty Full Useful Life Exhaust Emission Standards (Grams per Mile)]
Bin     NOx     NMOG     CO     HCHO     PM
5       0.07    0.090    4.2    0.018    0.01

[p. 6734, preamble]
The program we are finalizing today will ultimately require each manufacturer’s average full life NOX emissions over all of its Tier 2 vehicles to meet a NOX standard of 0.07 g/mi each model year. Manufacturers will have the flexibility to certify Tier 2 vehicles to different sets of exhaust standards that we refer to as ‘‘bins,’’ but will have to choose the bins so that their corporate sales weighted average full life NOX level for their Tier 2 vehicles is no more than the 0.07 g/mi.

[Editorial unit reminder, not a quote: 1 mile = 1.609344 kilometers. The study prints 0.043 g/km as its rounded benchmark. Compare PEMS route g/km against its g/km benchmark; do not call an on-road PEMS result a certification-cycle compliance verdict.]
