As used in these rules, unless the context otherwise
requires:
3.1 "Alternative Fuel," as
defined under these rules, means compressed natural gas, propane, ethanol,
electricity or any other fuel, but excludes those fuels made, in part or in
whole, from petroleum products.
3.2 "Alternative Fuel Vehicles" are vehicles
propelled with a fuel derived solely from resources other than petroleum. No
part of an alternative fuel vehicle, as defined under these rules, may be
propelled by petroleum products.
3.3 "Department of Transportation" is the
Colorado Department of Transportation, its departments and divisions, and
includes the Colorado Tolling Enterprise.
3.4 "Hybrid Vehicle(s)" are light duty
vehicles and light duty trucks up to 8500 lbs. Gross Vehicle Weight Rating
("GVWR"). GVWR must be certified by the U.S. Environmental Protection Agency as
meeting the criteria of either paragraph 3.4.1 or 3.4.2 of this section:
3.4.1 It is an alternative fuel vehicle
meeting the low emission standards set forth in subsection 3.4.2.1
below;
3.4.2 It meets the following
criteria in this paragraph:
3.4.2.1 It must
be certified by the U.S. Environmental Protection Agency as low emission
vehicles meeting emission standards that are as or more stringent than the tier
2 bin 5 emission standards as defined in Table S04-1 of
40 CFR
86.1811-04; and
3.4.2.2 The unadjusted city fuel economy of
the vehicle must be at least 50 percent higher than the city fuel economy of a
comparable gasoline-fueled vehicle as determined under
40 CFR
600.207-93; or
3.4.2.3 The unadjusted combined city-highway
fuel economy of the vehicle must be at least 25 percent higher than the
unadjusted combined city-highway fuel economy of a comparable gasoline-fueled
vehicle as determined under 40 CFR 600.207-93; or
3.4.2.4 For Hybrid Vehicles with no similar
gasoline counterpart, the Department of Transportation will determine the
candidate vehicles by calculating the median unadjusted city fuel economy
values for all gasoline vehicles in the same comparable vehicle class as
defined in the U.S. Environmental Protection Agency's annual Fuel Economy
Guide, jointly published by the U.S. Environmental Protection Agency and the
U.S. Department of Energy. The Department of Transportation will compare the
unadjusted city fuel economy value of the candidate Hybrid Vehicle, as
determined under 40 CFR
600.207-93, to the median unadjusted city
fuel economy for the comparison vehicle in the same vehicle class.
