On-Road Vehicle and Engine Emission Regulations

Version of section 24 from 2014-01-01 to 2015-07-15:

  •  (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 15 years or 240,000 km (150,000 miles), a company may, in the equation 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.
