PART C—CLEAN FUEL VEHICLES
§ 7581. Definitions
For purposes of this part—
(1) Terms defined in part A
The definitions applicable to part A under
section 7550 of this title shall also apply for
purposes of this part.
(2) Clean alternative fuel
The term ‘‘clean alternative fuel’’ means
any fuel (including methanol, ethanol, or
other alcohols (including any mixture thereof
containing 85 percent or more by volume of
such alcohol with gasoline or other fuels), re-
formulated gasoline, diesel, natural gas, lique-
fied petroleum gas, and hydrogen) or power
source (including electricity) used in a clean-
fuel vehicle that complies with the standards
and requirements applicable to such vehicle
under this subchapter when using such fuel or
power source. In the case of any flexible fuel
vehicle or dual fuel vehicle, the term ‘‘clean
alternative fuel’’ means only a fuel with re-
spect to which such vehicle was certified as a
clean-fuel vehicle meeting the standards appli-
cable to clean-fuel vehicles under section
7583(d)(2) of this title when operating on clean
alternative fuel (or any CARB standards which
replaces such standards pursuant to section
7583(e) of this title).
(3) NMOG
The
term
nonmethane
organic
gas
(‘‘NMOG’’) means the sum of nonoxygenated
and oxygenated hydrocarbons contained in a
gas sample, including, at a minimum, all
oxygenated organic gases containing 5 or
fewer carbon atoms (i.e., aldehydes, ketones,
alcohols, ethers, etc.), and all known alkanes,
alkenes, alkynes, and aromatics containing 12
or fewer carbon atoms. To demonstrate com-
pliance with a NMOG standard, NMOG emis-
sions shall be measured in accordance with the
‘‘California Non-Methane Organic Gas Test
Procedures’’. In the case of vehicles using
fuels other than base gasoline, the level of
NMOG emissions shall be adjusted based on
the reactivity of the emissions relative to ve-
hicles using base gasoline.
(4) Base gasoline
The term ‘‘base gasoline’’ means gasoline
which meets the following specifications:
Specifications of Base Gasoline Used as
Basis for Reactivity Readjustment:

The Administrator shall modify the defini-
tions of NMOG, base gasoline, and the methods
for making reactivity adjustments, to conform
to the definitions and method used in Cali-
fornia under the Low-Emission Vehicle and
Clean Fuel Regulations of the California Air
Resources Board, so long as the California
definitions are, in the aggregate, at least as
protective of public health and welfare as the
definitions in this section.
(5) Covered fleet
The term ‘‘covered fleet’’ means 10 or more
motor vehicles which are owned or operated
by a single person. In determining the number
of vehicles owned or operated by a single per-
son for purposes of this paragraph, all motor
vehicles owned or operated, leased or other-
wise controlled by such person, by any person
who controls such person, by any person con-

TITLE 42—THE PUBLIC HEALTH AND WELFARE
§ 7582
trolled by such person, and by any person
under common control with such person shall
be treated as owned by such person. The term
‘‘covered fleet’’ shall not include motor vehi-
cles held for lease or rental to the general pub-
lic, motor vehicles held for sale by motor vehi-
cle dealers (including demonstration vehicles),
motor vehicles used for motor vehicle manu-
facturer product evaluations or tests, law en-
forcement and other emergency vehicles, or
nonroad vehicles (including farm and con-
struction vehicles).
(6) Covered fleet vehicle
The term ‘‘covered fleet vehicle’’ means only
a motor vehicle which is—
(i) in a vehicle class for which standards
are applicable under this part; and
(ii) in a covered fleet which is centrally
fueled (or capable of being centrally fueled).
No vehicle which under normal operations is
garaged at a personal residence at night shall
be considered to be a vehicle which is capable
of being centrally fueled within the meaning
of this paragraph.
(7) Clean-fuel vehicle
The term ‘‘clean-fuel vehicle’’ means a vehi-
cle in a class or category of vehicles which has
been certified to meet for any model year the
clean-fuel vehicle standards applicable under
this part for that model year to clean-fuel ve-
hicles in that class or category.
(July 14, 1955, ch. 360, title II, § 241, as added Pub.
L. 101–549, title II, § 229(a), Nov. 15, 1990, 104 Stat.

hicles
(a) Promulgation of standards
Not later than 24 months after November 15,
1990, the Administrator shall promulgate regula-
tions under this part containing clean-fuel vehi-
cle standards for the clean-fuel vehicles speci-
fied in this part.
(b) Other requirements
Clean-fuel vehicles of up to 8,500 gvwr subject
to standards set forth in this part shall comply

chapter (such as requirements relating to on-
board diagnostics, evaporative emissions, etc.)
which are applicable to conventional gasoline-
fueled vehicles of the same category and model
year, except as provided in section 7584 of this
title with respect to administration and enforce-
ment, and except to the extent that any such re-
quirement is in conflict with the provisions of
this part. Clean-fuel vehicles of 8,500 gvwr or
