TITLE 49—TRANSPORTATION
§ 32905
49:32904(b)(1)(A) made by section 371(b)(1) of the North
American Free Trade Implementation Act (Public Law
103–182, 107 Stat. 2128). The words ‘‘(except as provided
in paragraph (3))’’ are substituted for ‘‘Except as pro-
vided in subparagraph (G)’’ because of the restatement
of 15:2003(b)(2)(G) as 49:32904(b)(3).
In subsection (b)(3)(A), the words ‘‘is imported . . .
more than 30 days after’’ are substituted for ‘‘is not im-
ported . . . prior to the expiration of 30 days following’’
for clarity and consistency with title 49, United States
Code.
In subsection (b)(3)(C), the words ‘‘and the EPA Ad-
ministrator may prescribe rules for purposes of car-
rying out this subparagraph’’ are omitted as surplus be-
cause of the authority of the Administrator to pre-
scribe regulations under 49:32910(d). The amendment
made by section 371(b)(2) of the North American Free
Trade Implementation Act (Public Law 103–182, 107
Stat. 2128) is not given effect because the last sentence
of section 503(b)(2)(E) of the Motor Vehicle and Cost
Savings Act (Public Law 92–513, 86 Stat. 947) was omit-
ted in the restatement of title 49 because of the author-
ity of the Administrator to prescribe regulations under
49:32910(d).

EFFECT OF REPEAL ON EXISTING EXEMPTIONS
Pub. L. 110–140, title I, § 113(b), (c), Dec. 19, 2007, 121
Stat. 1508, provided that:
‘‘(b) EFFECT OF REPEAL ON EXISTING EXEMPTIONS.—
Any exemption granted under section 32904(b)(6) of title
49, United States Code, prior to the date of the enact-
ment of this Act [Dec. 19, 2007] shall remain in effect
subject to its terms through model year 2013.
‘‘(c) ACCRUAL
AND USE
OF CREDITS.—Any manufac-
turer holding an exemption under section 32904(b)(6) of
title 49, United States Code, prior to the date of the en-
actment of this Act may accrue and use credits under
sections 32903 and 32905 of such title beginning with
model year 2011.’’
§ 32905. Manufacturing incentives for alternative
fuel automobiles
(a) DEDICATED AUTOMOBILES.—Except as pro-
vided in subsection (c) of this section or section
32904(a)(2) of this title, for any model of dedi-
cated automobile manufactured by a manufac-
turer after model year 1992, the fuel economy
measured for that model shall be based on the
fuel content of the alternative fuel used to oper-
ate the automobile. A gallon of a liquid alter-
native fuel used to operate a dedicated auto-
mobile is deemed to contain .15 gallon of fuel.
(b) DUAL
FUELED
AUTOMOBILES.—Except as
provided in subsection (d) of this section or sec-
tion 32904(a)(2) of this title, for any model of
dual fueled automobile manufactured by a man-
ufacturer in model years 1993 through 2019, the
Administrator of the Environmental Protection
Agency shall measure the fuel economy for that
model by dividing 1.0 by the sum of—
(1) .5 divided by the fuel economy measured
under section 32904(c) of this title when oper-
ating the model on gasoline or diesel fuel; and
(2) .5 divided by the fuel economy—
(A) measured under subsection (a) when
operating the model on alternative fuel; or
(B) measured based on the fuel content of
B20 when operating the model on B20, which
is deemed to contain 0.15 gallon of fuel.
(c) GASEOUS FUEL DEDICATED AUTOMOBILES.—
For any model of gaseous fuel dedicated auto-
mobile manufactured by a manufacturer after
model year 1992, the Administrator shall meas-
ure the fuel economy for that model based on
Page 970
TITLE 49—TRANSPORTATION
§ 32905
the fuel content of the gaseous fuel used to oper-
ate the automobile. One hundred cubic feet of
natural gas is deemed to contain .823 gallon
equivalent of natural gas. The Secretary of
Transportation shall determine the appropriate
gallon equivalent of other gaseous fuels. A gal-
lon equivalent of gaseous fuel is deemed to have
a fuel content of .15 gallon of fuel.
(d)
GASEOUS
FUEL
DUAL
FUELED
AUTO-
MOBILES.—For any model of gaseous fuel dual
fueled automobile manufactured by a manufac-
turer in model years 1993 through 2019, the Ad-
ministrator shall measure the fuel economy for
that model by dividing 1.0 by the sum of—
(1) .5 divided by the fuel economy measured
under section 32904(c) of this title when oper-
ating the model on gasoline or diesel fuel; and
(2) .5 divided by the fuel economy measured
under subsection (c) of this section when oper-
ating the model on gaseous fuel.
(e) ELECTRIC DUAL FUELED AUTOMOBILES.—
(1) IN GENERAL.—At the request of the manu-
facturer, the Administrator may measure the
fuel economy for any model of dual fueled
automobile manufactured after model year
2015 that is capable of operating on electricity
in addition to gasoline or diesel fuel, obtains
its electricity from a source external to the
vehicle, and meets the minimum driving range
requirements established by the Secretary for
dual fueled electric automobiles, by dividing
1.0 by the sum of—
(A) the percentage utilization of the model
on gasoline or diesel fuel, as determined by
a formula based on the model’s alternative
fuel range, divided by the fuel economy
measured under section 32904(c); and
(B) the percentage utilization of the model
on electricity, as determined by a formula
based on the model’s alternative fuel range,
divided by the fuel economy measured under
section 32904(a)(2).
(2) ALTERNATIVE CALCULATION.—If the manu-
facturer does not request that the Adminis-
trator calculate the manufacturing incentive
for its electric dual fueled automobiles in ac-
cordance with paragraph (1), the Adminis-
trator shall calculate such incentive for such
automobiles manufactured by such manufac-
turer after model year 2015 in accordance with
subsection (b).
(f) FUEL ECONOMY CALCULATIONS.—The Admin-
istrator shall calculate the manufacturer’s aver-
age fuel economy under section 32904(a)(1) of
this title for each model described under sub-
sections (a)–(d) of this section by using as the
denominator the fuel economy measured for
each model under subsections (a)–(d).
(g) FUEL ECONOMY INCENTIVE REQUIREMENTS.—
In order for any model of dual fueled automobile
to be eligible to receive the fuel economy incen-
tives included in section 32906(a) and (b), a label
shall be attached to the fuel compartment of
each dual fueled automobile of that model, noti-
fying that the vehicle can be operated on an al-
ternative fuel and on gasoline or diesel, with the
form of alternative fuel stated on the notice.
This requirement applies to dual fueled auto-
mobiles manufactured on or after September 1,
2006.

§ 32906. Maximum fuel economy increase for al-
ternative fuel automobiles
(a) IN GENERAL.—For each of model years 1993
through 2019 for each category of automobile
(except an electric automobile or, beginning
with model year 2016, an alternative fueled auto-
mobile that uses a fuel described in subpara-
graph (E) of section 32901(a)(1)), the maximum
increase in average fuel economy for a manufac-
turer attributable to dual fueled automobiles
is—
(1) 1.2 miles a gallon for each of model years
1993 through 2014;
(2) 1.0 miles per gallon for model year 2015;
(3) 0.8 miles per gallon for model year 2016;
(4) 0.6 miles per gallon for model year 2017;
(5) 0.4 miles per gallon for model year 2018;
(6) 0.2 miles per gallon for model year 2019;
and
(7) 0 miles per gallon for model years after
2019.
(b) CALCULATION.—In applying subsection (a),
the Administrator of the Environmental Protec-
tion Agency shall determine the increase in a
manufacturer’s average fuel economy attrib-
utable to dual fueled automobiles by subtracting
from the manufacturer’s average fuel economy
calculated under section 32905(f) the number
equal to what the manufacturer’s average fuel
economy would be if it were calculated by the
formula under section 32904(a)(1) by including as
the denominator for each model of dual fueled
automobiles the fuel economy when the auto-
mobiles are operated on gasoline or diesel fuel.

tation on—
(A) whether the manufacturer will comply
with an applicable average fuel economy
standard under section 32902 of this title for

paragraph (1) of this subsection during the 30
days—
(A) before the beginning of each model year;
and
(B) beginning on the 180th day of the model
year.
