2. (1) Despite section 10 of the Regulations, a company may, in respect of its passenger automobiles and light trucks of a given model year that are emergency vehicles, elect to be exempted from the requirement of conforming to the exhaust emission standards for nitrous oxide (N2O) and methane (CH4) set out in section 1818(f)(1) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR, if it reports that election in its end of model year report.

where
A is the total number of passenger automobiles or light trucks of the test group;
B is the exhaust emission standard for methane (CH4) set out in section 1818(f)(1) of Title 40, chapter I, subchapter C, part 86, subpart S, of the CFR, for the model year in question, expressed in grams per mile;
C is the alternative exhaust emission standard for methane (CH4) to which the company has elected to certify the test group, expressed in grams per mile; and
D is the assumed total mileage of the vehicles in question, namely,
(a) 195,264 miles for a fleet of passenger automobiles, or
