Alternative method for measuring drag area (4) Instead of the default method referred to in section 526 of Title 40, chapter I, subchapter U, part 1037, subpart F, of the CFR, a company may elect to measure a trailer’s drag area (C d A ) in accordance with any other method referred to in that section, if the test results are adjusted to correlate with the test results that would be obtained if the default method were used, as specified in that section, and if (a) in the case of a trailer that is covered by an EPA certificate, the election has been approved by the EPA for that trailer and the company provides the Minister with evidence of the EPA approval; and (b) in the case of a trailer that is not covered by an EPA certificate, the company provides the Minister with evidence demonstrating that the alternative method for measuring the trailer’s drag area referred to in this subsection is more representative of that trailer’s drag area. Calculation using fleets and subfleets (5) For the 2027 model year and subsequent model years, a company may elect to comply with subsection (1) by grouping all of its full-aero box van trailers of a given model year into fleets or subfleets, as the case may be, in accordance with section 18 and participating in the CO 2 emission credit system set out in sections 47.1 to 47.5. Family emission limit (6) For the purposes of subsection (5), every full-aero box van trailer included within a fleet or subfleet, as the case may be, that is of a type referred to in column 1 of the table to this subsection must, for the duration of its useful life, conform to a CO 2 family emission limit that does not exceed the CO 2 emission limit set out in column 2.
