  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.

• (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:
