Calculation of Fleet Average NOx Values

  •  (1) Subject to section 25, for each of its fleets referred to in sections 21 to 23, a company shall calculate the average NOx value in accordance with the following formula:

    [Σ (A x B)]/C

    where

    A
    is the NOx emission standard for each full useful life emission bin,
    B
    is the number of vehicles in the fleet that conform to that NOx emission standard, and
    C
    is the total number of vehicles in the fleet.
  • (2) The average NOx value for the fleet shall be rounded to the same number of significant figures that are contained in the total number of vehicles in the fleet in the denominator in subsection (1), but to at least three decimal places.

  • (3) If a company’s fleet includes any hybrid electric vehicle that is covered by an EPA certificate, the average NOx value calculated under subsection (1) may be lowered by applying one or more hybrid electric vehicle NOx contribution factors as long as

    • (a) each factor has been approved by the EPA in accordance with the provisions of the CFR;

    • (b) each factor is applied in the same manner as it is applied by the EPA; and

    • (c) evidence of the EPA approval is provided to the Minister in the end of model year report referred to in section 32.

  • (4) Subject to subsection (5), in respect of any of its vehicles that conform to a NOX emission standard for an extended useful life of 150,000 miles, a company may, in the formula in subsection (1), replace that standard, for each of those vehicles, with that standard multiplied by 0.85, rounded to at least three decimal places.

  • (5) A company may only replace a NOx emission standard as described in subsection (4) if the vehicle complies with any standards that may be applicable at the intermediate useful life.

  • (6) In respect of the 2004 and 2005 model years, a company may multiply by 2 the number of vehicles that conform to full useful life emission bin 1, and multiply by 1.5 the number of vehicles that conform to full useful life emission bin 2, when calculating one of the following:

    • (a) the denominator in subsection (1); or

    • (b) “total number of vehicles in the fleet” in the equation for calculating credits in subsection 26(2).

  • (7) When calculating the average NOx value under subsection (1) for a fleet of the 2004 model year, a company may include all vehicles of that model year, including those whose main assembly was completed before January 1, 2004.

Fleet Average NMOG + NOX Standards — 2017 and Later Model Years

Light-duty Vehicles, Light-duty Trucks and Medium-duty Passenger Vehicles

  •  (1) Subject to subsection (2), for the 2017 to 2024 model years, the average NMOG + NOX value for each of the following fleets of a specific model year shall not exceed the applicable fleet average NMOG + NOX standard set out for the model year in question in Tables 3 and 4 of section 1811 of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR:

    • (a) a company’s fleet that is composed of all of its light-duty vehicles and light-duty trucks 1 to which the applicable NMOG + NOX standard applies for a useful life of 120,000 miles;

    • (b) a company’s fleet that is composed of all of its light-duty vehicles and light-duty trucks 1 to which the applicable NMOG + NOX standard applies for a useful life of 150,000 miles; and

    • (c) a company’s fleet that is composed of all of its light-duty trucks 2, heavy light-duty trucks and medium-duty passenger vehicles.

  • (2) For the 2017 model year, the fleet referred to in paragraph (1)(c) is composed only of all of a company’s light-duty trucks 2.

  • SOR/2015-186, s. 27.

 For the 2025 and later model years, the average NMOG + NOX value for each of the following fleets of a specific model year shall not exceed the applicable fleet average NMOG + NOX standard set out in Table 1 of section 1811 of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR:

  • (a) a company’s fleet that is composed of all of its light-duty vehicles and light-duty trucks 1 to which the applicable NMOG + NOX standard applies for a useful life of 120,000 miles;

  • (b) a company’s fleet that is composed of all of its light-duty vehicles and light-duty trucks 1 to which the applicable NMOG + NOX standard applies for a useful life of 150,000 miles; and

  • (c) a company’s fleet that is composed of all of its light-duty trucks 2, heavy light-duty trucks and medium-duty passenger vehicles.

  • SOR/2015-186, s. 27.

 For the 2018 to 2021 model years, the average NMOG + NOX value for each fleet that is composed of all of a company’s Class 2B vehicles or all of a company’s Class 3 vehicles of a specific model year shall not exceed the applicable fleet average NMOG + NOX standard set out for the model year in question in Table 4 of section 1816 of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR.

  • SOR/2015-186, s. 27.

 For the 2022 and later model years, the average NMOG + NOX value for each fleet that is composed of all of a company’s Class 2B vehicles or all of a company’s Class 3 vehicles of a specific model year shall not exceed the applicable fleet average NMOG + NOX standard set out in Table 1 of section 1816 of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR.

  • SOR/2015-186, s. 27.

Calculation of Fleet Average NMOG + NOX Values

  •  (1) Subject to section 25.1, for each of a company’s fleets referred to in sections 24.1 to 24.4, the company shall calculate the average NMOG + NOX value in accordance with the following formula:

    [Σ (A × B)]/C

    where

    A
    is the NMOG + NOX standard for each full useful life emission bin;
    B
    is the number of vehicles in the fleet that conform to the NMOG + NOX standard for the full useful life emission bin in question; and
    C
    is the total number of vehicles in the fleet.
  • (2) The average NMOG + NOX value for the fleet shall be rounded to the same number of significant figures that are contained in the total number of vehicles in the fleet in the denominator in subsection (1), but to at least three decimal places.
