ployment of idle reduction and energy con-
servation technologies .
(ii) 
PRIORITY.—The 
Administrator
shall give priority to the deployment of idle

APPROPRIA-
TIONS.—There are authorized to be appro-
priated to the Administrator to carry out

2007, and $45,000,000 for fiscal year
2008.
(ii) COST SHARING.—Subject to clause
(iii), the Administrator shall require at
least 50 percent of the costs directly and
specifically related to any project under
this section to be provided from non-Fed-
eral sources.
(iii) NECESSARY
AND
APPROPRIATE
REDUCTIONS.—The Administrator may re-
duce the non-Federal requirement under
322
clause (ii) if the Administrator determines
that the reduction is necessary and appro-
priate to meet the objectives of this sec-
tion.
(5) IDLING LOCATION STUDY.—
(A) IN GENERAL.—Not later than 90 days
after the date of enactment of this Act, the Ad-
ministrator, in consultation with the Secretary
of Transportation, shall commence a study to
analyze all locations at which heavy-duty vehi-
cles stop for long-duration idling, including—
(i) truck stops;
(ii) rest areas;
(iii) border crossings;
(iv) ports;
(v) transfer facilities; and
(vi) private terminals.
(B) DEADLINE
FOR
COMPLETION.—Not
later than 180 days after the date of enactment
of this Act, the Administrator shall—
(i) complete the study under subpara-
graph (A); and
(ii) prepare and make publicly avail-
able 1 or more reports of the results of the
study.
323
(c) VEHICLE WEIGHT EXEMPTION.—Section 127(a)
of title 23, United States Code, is amended—
(1) by designating the first through eleventh
sentences as paragraphs (1) through (11), respec-
tively; and
(2) by adding at the end the following:
‘‘(12) HEAVY DUTY VEHICLES.—
‘‘(A) IN
GENERAL.—Subject to subpara-
graphs (B) and (C), in order to promote reduc-
tion of fuel use and emissions because of engine
idling, the maximum gross vehicle weight limit
and the axle weight limit for any heavy-duty ve-
hicle equipped with an idle reduction technology
shall be increased by a quantity necessary to
compensate for the additional weight of the idle
reduction system.
‘‘(B) MAXIMUM WEIGHT INCREASE.—The
weight increase under subparagraph (A) shall
be not greater than 400 pounds.
‘‘(C) PROOF.—On request by a regulatory
agency or law enforcement agency, the vehicle
operator shall provide proof (through dem-
onstration or certification) that—
‘‘(i) the idle reduction technology is
fully functional at all times; and
324
‘‘(ii) the 400-pound gross weight in-
crease is not used for any purpose other
than the use of idle reduction technology
described in subparagraph (A).’’.
(d) REPORT.—Not later than 60 days after the date
on which funds are initially awarded under this section,
and on an annual basis thereafter, the Administrator shall
submit to Congress a report containing—
(1) an identification of the grant recipients, a
description of the projects to be funded and the
amount of funding provided; and
(2) an identification of all other applicants that
submitted applications under the program.
SEC. 757. BIODIESEL ENGINE TESTING PROGRAM.
(a) IN GENERAL.—Not later that 180 days after the
date of enactment of this Act, the Secretary shall initiate
a partnership with diesel engine, diesel fuel injection sys-
tem, and diesel vehicle manufacturers and diesel and bio-
diesel fuel providers, to include biodiesel testing in ad-
vanced diesel engine and fuel system technology.
(b) SCOPE.—The program shall provide for testing
to determine the impact of biodiesel from different sources
on current and future emission control technologies, with
emphasis on—
325
(1) the impact of biodiesel on emissions war-
ranty, in-use liability, and antitampering provisions;
(2) the impact of long-term use of biodiesel on
engine operations;
(3) the options for optimizing these technologies
for both emissions and performance when switching
between biodiesel and diesel fuel; and
(4) the impact of using biodiesel in these fuel-
ing systems and engines when used as a blend with
2006 Environmental Protection Agency-mandated
diesel fuel containing a maximum of 15-parts-per-
million sulfur content.
(c) REPORT.—Not later than 2 years after the date
of enactment of this Act, the Secretary shall provide an
interim report to Congress on the findings of the program,
including a comprehensive analysis of impacts from bio-
diesel on engine operation for both existing and expected
future diesel technologies, and recommendations for en-
suring optimal emissions reductions and engine perform-
ance with biodiesel.
(d) AUTHORIZATION
OF APPROPRIATIONS.—There
are authorized to be appropriated $5,000,000 for each of
fiscal years 2006 through 2010 to carry out this section.
(e) DEFINITION.—For purposes of this section, the
term ‘‘biodiesel’’ means a diesel fuel substitute produced
326
from nonpetroleum renewable resources that meets the
registration requirements for fuels and fuel additives es-
tablished by the Environmental Protection Agency under
section 211 of the Clean Air Act (42 U.S.C. 7545) and
that meets the American Society for Testing and Materials
D6751–02a Standard Specification for Biodiesel Fuel
