    • (f) in the case of a Class 8 sleeper cab, if the tractor is equipped with idle reduction technology that conforms to section 660 of Title 40, chapter I, subchapter U, part 1037, subpart G, of the CFR, and that automatically shuts off the main engine after 300 seconds or less, the corresponding value is 5 grams of CO2 per tonne-mile or if applicable, is calculated in accordance with section 660(c) of Title 40, chapter I, subchapter U, part 1037, subpart G, of the CFR.

  • Marginal note:Weight reduction technologies

    (3) For greater certainty, CO2 emission credits for weight reduction technologies that are not referred to in paragraph (2)(e) may be obtained under section 41.

  • Marginal note:Calculation of coefficient of aerodynamic drag

    (4) Subject to subsections (5) and (6), the coefficient of aerodynamic drag (CD) is determined by

    • (a) measuring the drag area (CDA) in accordance with the coastdown testing referred to in subpart F of Title 40, chapter I, subchapter U, part 1037, of the CFR, rounded to two decimal places and taking into account the following criteria:

      • (i) high-roof tractors must be tested with the standard trailer referred to in section 501(g) of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR, and low-roof and mid-roof tractors must be tested without a trailer, unless they are tested with a trailer to evaluate innovative technologies, and

      • (ii) the tractors and standard trailers referred to in section 501(g) of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR must be equipped with tires that are mounted on steel rims in accordance with section 521(b)(2) of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR; and

    • (b) determining, in accordance with section 520(b) of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR, the tractor’s coefficient of aerodynamic drag (CD) and bin level that correspond to the tractor’s drag area (CDA) calculated in paragraph (a).

  • Marginal note:Alternative bin level

    (5) For low-roof and mid-roof tractors, the bin level may be determined using the bin level of an equivalent high-roof tractor as follows:

    • (a) if the equivalent high-roof tractor is in Bin I or Bin II, the low-roof and mid-roof tractors must be in Bin I; or

    • (b) if the equivalent high-roof tractor is in Bin III, Bin IV or Bin V, the low-roof and mid-roof tractors must be in Bin II.

  • Marginal note:Alternative method for measuring drag area

    (6) Instead of the method referred to in paragraph (4)(a), a company may elect to measure the tractor’s drag area (CDA) in accordance with any other method described in subpart F of Title 40, chapter I, subchapter U, part 1037, of the CFR, if,

    • (a) in the case of a tractor that is covered by an EPA certificate, the election has been approved by the EPA for that tractor, under section 521(c) of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR, and the company provides the Minister with evidence of the EPA approval; and

    • (b) in the case of a tractor that is not covered by an EPA certificate, the company provides the Minister with evidence demonstrating that the alternative method for measuring the tractor’s drag area referred to in this subsection is more representative of that tractor’s drag area.

  • Marginal note:Option to conform to higher vehicle service class

    (7) For any given vehicle referred to in subsection (1), a company may elect to conform to the emission standards and useful life applicable to a higher vehicle service class in which case the company must not obtain credits for those vehicles when participating in the CO2 emission credit system set out in sections 34 to 47.

  • Marginal note:Calculation using fleets and subfleets

    (8) A company may elect to comply with subsection (1) by grouping all its tractors and incomplete tractors of a given model year into fleets or subfleets, as the case may be, in accordance with section 18 and participating in the CO2 emission credit system set out in sections 34 to 47.

  • Marginal note:Family emission limit

    (9) For the purposes of subsection (8), every tractor and incomplete tractor within a fleet or subfleet, as the case may be, must conform to the CO2 family emission limit determined by the company for the fleet or subfleet of the vehicle, as the case may be, and corresponding to the value determined for B in the formula set out in paragraph 35(1)(c).

  • Marginal note:Engines meeting requirements

    (10) Every tractor and incomplete tractor of the 2014 and subsequent model years must be equipped with a heavy-duty engine that meets the requirements of these Regulations.
