vehicles
(a) Study and analysis
(1) The Administrator shall conduct a study
concerning the effects on health and welfare of
particulate emissions from motor vehicles or
motor vehicle engines to which section 7521 of
this title applies. Such study shall characterize
and quantify such emissions and analyze the re-
lationship of such emissions to various fuels and

ture and degree of endangerment to public health or

matter.
§ 7549. High altitude performance adjustments
(a) Instruction of the manufacturer
(1) Any action taken with respect to any ele-
ment of design installed on or in a motor vehicle
or motor vehicle engine in compliance with reg-
ulations under this subchapter (including any
alteration or adjustment of such element), shall
be treated as not in violation of section 7522(a)
of this title if such action is performed in ac-
cordance with high altitude adjustment instruc-
tions provided by the manufacturer under sub-
section (b) and approved by the Administrator.
(2) If the Administrator finds that adjustments
or modifications made pursuant to instructions
of the manufacturer under paragraph (1) will not
insure emission control performance with re-
spect to each standard under section 7521 of this
title at least equivalent to that which would re-
sult if no such adjustments or modifications
were made, he shall disapprove such instruc-
tions. Such finding shall be based upon min-
imum engineering evaluations consistent with
good engineering practice.
(b) Regulations
(1) Instructions respecting each class or cat-
egory of vehicles or engines to which this sub-
chapter applies providing for such vehicle and
engine adjustments and modifications as may be
necessary to insure emission control perform-
ance at different altitudes shall be submitted by
the manufacturer to the Administrator pursuant
to regulations promulgated by the Adminis-
trator.
(2) Any knowing violation by a manufacturer
of requirements of the Administrator under
paragraph (1) shall be treated as a violation by
such manufacturer of section 7522(a)(3) of this
title for purposes of the penalties contained in
section 7524 of this title.
(3) Such instructions shall provide, in addition
to other adjustments, for adjustments for vehi-

cles moving from high altitude areas to low alti-
tude areas after the initial registration of such
vehicles.
(c) Manufacturer parts
No instructions under this section respecting
adjustments or modifications may require the
use of any manufacturer parts (as defined in sec-
tion 7522(a) of this title) unless the manufac-
turer demonstrates to the satisfaction of the
Administrator that the use of such manufac-
turer parts is necessary to insure emission con-
trol performance.
(d) State inspection and maintenance programs
Before January 1, 1981 the authority provided
by this section shall be available in any high al-
titude State (as determined under regulations of
the Administrator under regulations promul-
gated before August 7, 1977) but after December
31, 1980, such authority shall be available only in
any such State in which an inspection and main-
tenance program for the testing of motor vehi-
cle emissions has been instituted for the por-
tions of the State where any national ambient
air quality standard for auto-related pollutants
has not been attained.
(e) High altitude testing
(1) The Administrator shall promptly establish
at least one testing center (in addition to the
testing centers existing on November 15, 1990)
located at a site that represents high altitude
conditions, to ascertain in a reasonable manner
whether, when in actual use throughout their
useful life (as determined under section 7521(d)
of this title), each class or category of vehicle
and engines to which regulations under section
7521 of this title apply conforms to the emissions
standards established by such regulations. For
purposes of this subsection, the term ‘‘high alti-
tude conditions’’ refers to high altitude as de-
fined in regulations of the Administrator in ef-
fect as of November 15, 1990.
(2) The Administrator, in cooperation with the
Secretary of Energy and the Administrator of
the Federal Transit Administration, and such
other agencies as the Administrator deems ap-
propriate, shall establish a research and tech-
nology assessment center to provide for the de-
velopment
and
evaluation
of
less-polluting
heavy-duty engines and fuels for use in buses,
heavy-duty trucks, and non-road engines and ve-
hicles, which shall be located at a high-altitude
site that represents high-altitude conditions. In
establishing and funding such a center, the Ad-
ministrator shall give preference to proposals
which provide for local cost-sharing of facilities
and recovery of costs of operation through utili-
zation of such facility for the purposes of this
section.
(3) The Administrator shall designate at least
one center at high-altitude conditions to provide
research on after-market emission components,
dual-fueled vehicles and conversion kits, the ef-
fects of tampering on emissions equipment, test-
ing of alternate fuels and conversion kits, and
the development of curricula, training courses,
and materials to maximize the effectiveness of
inspection and maintenance programs as they
relate to promoting effective control of vehicle
emissions at high-altitude elevations. Pref-
erence shall be given to existing vehicle emis-
sions testing and research centers that have es-
tablished reputations for vehicle emissions re-
search and development and training, and that
possess in-house Federal Test Procedure capac-
ity.

**(a) Findings** The Congress finds—
(1) that the predominant part of the Nation’s population is located in its rapidly expanding metropolitan and other urban areas, which generally cross the boundary lines of local jurisdictions and often extend into two or more States;
(2) that the growth in the amount and complexity of air pollution brought about by urbanization, industrial development, and the increasing use of motor vehicles, has resulted in mounting dangers to the public health and welfare, including injury to agricultural crops and livestock, damage to and the deterioration of property, and hazards to air and ground transportation;
(3) that air pollution prevention (that is, the reduction or elimination, through any measures, of the amount of pollutants produced or created at the source) and air pollution control at its source is the primary responsibility of States and local governments; and
(4) that Federal financial assistance and leadership is essential for the development of cooperative Federal, State, regional, and local programs to prevent and control air pollution.
**(b) Declaration** The purposes of this subchapter are—
(1) to protect and enhance the quality of the Nation’s air resources so as to promote the public health and welfare and the productive capacity of its population;
(2) to initiate and accelerate a national research and development program to achieve the prevention and control of air pollution;
(3) to provide technical and financial assistance to State and local governments in connection with the development and execution of their air pollution prevention and control programs; and
(4) to encourage and assist the development and operation of regional air pollution prevention and control programs.
