Section 1037.102 - Exhaust emission standards for NO[X], HC, PM, and CO(a) Engines installed in heavy-duty vehicles are subject to criteria pollutant standards for NOX, HC, PM, and CO under 40 CFR part 86 through model year 2026 and 40 CFR part 1036 for model years 2027 and later.(b) Heavy-duty vehicles with no installed propulsion engine, such as battery electric vehicles, are subject to criteria pollutant standards under this part. The emission standards that apply are the same as the standards that apply for compression-ignition engines under 40 CFR 86.007-11 or 1036.104 for a given model year. (1) You may state in the application for certification that vehicles with no installed propulsion engine comply with all the requirements of this part related to criteria emission standards instead of submitting test data. Tailpipe emissions of criteria pollutants from vehicles with no installed propulsion engine are deemed to be zero.(2) Vehicles with no installed propulsion engines may not generate NOX credits. 88 FR 4635 , Jan. 24, 2023, as amended at 89 FR 29766 , Apr. 22, 2024 88 FR 4635 , 3/27/2023; as amended at 89 FR 29766 , 6/21/2024
