       TITLE I—AIR POLLUTION PREVENTION AND
                          CONTROL i

                     FINDINGS AND PURPOSES

  "SEC. 101. (a) 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 juris-
    dictions 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 develop-
    ment, and the increasing use of motor vehicles, has resulted
    in mounting dangers to the  public health and welfare, includ-
    ing injury to agricultural crops and livestock,  damage to and
    the deterioration of  property and  hazards to air and ground
    transportation;
       "(3) that the prevention and control of air  pollution at its
    source is the primary responsibility of States and local gov-
    ernments; 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) The purposes of  this title 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 de-
    velopment 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 opera-
    tion of regional  air pollution control programs.

           COOPERATIVE ACTIVITIES AND UNIFORM LAWS

  "SEC. 102. (a) The Administrator shall encourage cooperative
activities  by the States and local governments for  the prevention
  1 Clean Air Act (42 U-.S.C. 1857 et, seg.) includes the Clean Air Act of 1963 (P.L. 88-206),
and amendments  made by the  Motor Vehicle Air Pollution Control Act —P.L.  89-272
(October 20, 1965), the. Clean Air Act Amendments of 1966—P.L. 89-675 (October 15, 1966),
the  Air Quality Act of''-.l9ffJ-.jf-P.Li. 90-148 (November 21, 1967), and the  Clean Air Amend-
ments of 1970'—P.L. 91-604— (December 31, 1970).

and control of air pollution; encourage the enactment of improved
and, so far as practicable in the light of varying conditions and
needs, uniform State and local laws relating to the prevention and
control of air pollution; and encourage the making of agreements
and compacts between States for the prevention and control of air
pollution.
" (b) The Administrator shall cooperate with and encourage
cooperative activities by all Federal departments and agencies
having functions relating to the prevention and control of air
pollution, so as to assure the utilization in the Federal air pollu-
tion control program of all appropriate and available facilities
and resources within the Federal Government.
"(c) The consent of the Congress is hereby given to two or
more States to negotiate and enter into agreements or compacts,
not in conflict with any law or treaty of the United States, for (1)
'cooperative effort and mutual assistance for the prevention and
control of air pollution and the enforcement of their respective
laws relating thereto, and (2) the establishment of such agencies,
joint or otherwise, as they may deem desirable for making effec-
tive such agreements or compacts. No such agreement or compact
shall be binding or obligatory upon any State a party thereto
unless and until it has been approved by Congress. It is the intent
of Congress that no agreement or compact entered into between
States after the date of enactment of the Air Quality Act of 1967,
which relates to the control and abatement of air pollution in an
air quality control region, shall provide for participation by a
State which is not included (in whole or in part) in such air
quality control region.

" (b) For purposes of developing and carrying out implementa-
tion plans under section 110-
"(1) an air quality control region designated under this
section before the date of enactment of the Clean Air Amend-
ments of 1970, or a region designated after such date under
subsection (c), shall be an air quality control region; and.
"(2) the portion of such State which is not part of any such
designated region shall be an air quality control region, but

-------
9
such portion may be subdivided by the State into two Or more
air quality control regions with the approval of the Adminis-
trator. ..
"(c) The Administrator shall, within 90 days after the date
of enactment of the Clean Air Amendments of 1970, after con-
sultation with appropriate State and local authorities, designate
as an air quality control region any interstate area or major intra-

ment and maintenance of ambient air quality standards. The Ad".
ministrator shall immediately notify the Governors of the affected
States of any designation made under this subsectioh.
AIR QUALITY CRITERIA AND CONTROL TECHNIQUES
"SEC. 108. (a) (1) For the purpose of establishing national
primary and secondary ambient air quality. standards, the Ad-
ministrator shall within 30 days after the date of enactment of
the Clean Air Amendments of 1970 publish, and shall from time
to time thereafter revise, a list which includes each air pollutant-
"(A) which in his judgment has an adverse effect on pub-
lic health and welfare;
" (B) the presence of which in the ambient air results from
numerous or diverse mobile or stationary sources; and
" (C) for which air quality criteria had not been issued
before the date of enactment of the Clean Air Amendments of
1970, but for which he plans to issue air quality criteria
under this section. . .
"(2) The Administrator shall issue air quality criteria for an
air pollutant within 12 months after he has included such pol-
lutant in a list under paragraph (1). Air quality criteria for an
air pollutant shall accurately reflect the latest scientific knowledge
useful in indicating the kind and extent of all identifiable effects
on public health or welfare which may be expected from the pres-
ence of such pollutant in the ambient air, in varying quantities.
The criteria for an air pollutant,. to the extent practicable, shall
include information on- .
"(A) those variable factors (inCluding atmospheric condi-
tions) which of themselves or in combination with other fac-
tors may alter the effects on public health or welfare of such
air pollutant; .
" (B) the types of air pollutants which, when present in the
atmosphere, may interact with such pollutant to produce .an
adverse effect on public health or welfare; and
" (C) any known or anticipated adverse effects on welfare.
"(b) (1) Simultaneously with the issuance of criteria under
subsection (a), the Administrator shall, after consultation with
appropriate advisory committees and Federal departments and
agencies, issue to the States and appropriate air pollution control
agencies, information on air pollution control techniques, which
information shall include data. relating to the technology and costs
of emission control. Such information shall include such data as
are' available on attainable technology and alternative methods of

-------
10
prevention and 'control of air pollution. Such information s~all
also include data on alternative fuels, processes, and operatIng
methods which will result in elimination of significant reduction
of emissions.
"(2) In order to assist in the development of information on
pollution control techniques, the Administrator may establish a
standing consulting committee for each air pollutant included in
a list published pursuant to subsection (a) (1), which shall be
comprised of technically qualified individuals representative of
State and local governments, industry, and the academic com-
munity. Each such committee shall submit as appropriate, to the
Administrator, information related to that required in para-
graph (1).
"(c) The Administrator shall from time to time review, and,
as appropriate, modify, and reissue any criteria or information on
control techniques issued pursuant to this section.
"(d) The issuance of air quality criteria and information on
air pollution control techniques shall be announced in the Federal
Register and 'copies shall be made available to the general public.

NATIONAL AMBIENT AIR QUALITY STANDARDS
"SEC. 109. (a) (1) The Administrator
"(A) within 30 days after the date of enactment of the
Clean Air Amendments of 1970, shall publish proposed regu-
lations prescribing a national primary ambient air quality
standard and a national secondary ambient air quality stand-
ard for each air pollutant for which air quality criteria have
been issued prior to such date of enactment; and
"(B) after a reasonable time for interested persons to
submit written comments thereon (but no later than 90 days
after the initial publication of such proposed standards) shall
by regulation promulgate such proposed national primary
and secondary ambient air quality standards with such modi-
fications as he deems appropriate.
"(2) With respect to any air pollutant for which air quality
criteria are issued after the date of enactment of the Clean Air
Amendments of 1970, the Administrator shall publish, simultane-
ously with the issuance of such criteria and information, proposed
national primary and secondary ambient air quality standards
for any such pollutant. The procedure provided for in paragraph
(1) (B) of this subsection shall apply to the promulgation of such
standards.
"(b) (1) National primary ambient air quality standards, pre-
scribed under subsection (a) shall be ambient air quality stand-
ards the attainment and maintenance of which in the judgment
of the Administrator, based on such criteria and allowing an ade-
quate margin of safety, are requisite to protect the public health.
Such primary standards may be revised in the same manner as
promulgated.
"(2) Any national secondary ambient air quality standard pre-
scribedJl under subsection (a) shall specify a level of air quality
the attainment and maintenance of which in the judgment of the

-------
11
Administrator, based on such criteria, is requisite to protect the
public welfare from any known or anticipated adverse effects
associated with the presence of such air pollutant in the ambient
air. Such secondary standards may be revised in the same man-
ner as promulgated.
IMPLEMENTATION PLANS
"SEC. 110. (a) (1) Each State shall, after reasonable notice and
public hearings, adopt and submit to the Administrator, within
nine months after the promulgation of a national primary ambient

"(2) The Administrator shall, within four months after the
date required for submission of a plan under paragraph (1), ap-
prove or disapprove such plan for each portion thereof. The Ad-
ministrator shall approve such plan, or any portion thereof, if he
determines that it was adopted after reasonable notice and hear-
ing and that-
"(A) (i) in the case of a plan implementing a national
primary ambient air quality standard, it provides for the at-
tainment of such primary standard as expeditiously as prac-
ticable but (subject to subsection (e» in no case later than
three years from the date of approval of such plan (or any
revision thereof to take account of a revised primary stand-
ard) ; and, (ii) in the case of a plan implementing a national
secondary ambient air quality standard, it specifies a reason-
able time at which such secondary standard will be attained;
" (B) it includes emission limitations, schedules, and tim'e-

tablished pursuant to this Act, which reports shall be avail-
able at reasonable times for public inspection; and (v) for
authority comparable to that in section 303, and adequate
contingency plans to implement such authority;
" (G) it provides, to the extent necessary and practicable,
for periodic inspection and testing of motor vehicles to en-
force compliance with applicable emission standards; and
"(H) it provides for revision, after public hearings, of
such plan (i) from time to time as may be necessary to take
account of revisions of such national primary or secondary
ambient air quality standard or the availability of improved
or. more expeditious methods of achieving such primary or
secondary- standard; or (ii) whenever the Administrator
finds on the basis of information available to him that the
plan is substantially inadequate to achieve the national am-
bient air quality primary or secondary standard which it
implements.
"(3) The Administrator shall approve any revision of an im-
plementation plan applicable to an air quality control region if
he determines that it meets the requirements. of paragraph (2)
and has been adopted by the State after reasonable notice and
public hearings. .
"(4) The procedure referred to in paragraph (2) (D) for re-
view, prior to construction or modification, of the location of
new sources shall (A) provide for adequate authority to prevent
the construction or modification of any new source to which a
standard of performance under Section 111 will apply at any
location which the State determines will prevent the attainment
or maintenance within any air quality control region (or portion
thereof) within such State of a national ambient air quality pri-
mary or secondary standard, and (B) require that prior to
commencing construction or modification of any such source, the
owner or operator thereof shall submit to such State such infor-
mation as may be necessary to permit the State to make a deter-
mination under clause (A).

-------
13
" (b) The Administrator may, wherever he determines neces-
sary, extend the period. for submission of any plan or portion
thereof which implements a national secondary ambient air qual-
ity standarq for a period not to exceed eighteen months from the
date otherwise required for submission of such plan.
"(c) The Administrator shall, after consideration of any State
hearing record, promptly prepare and publish proposed regula-
tions setting forth an implementation plan, or portion thereof,
for a State if-
"(1) The State fails to submit an implementation plan for
any national ambient air quality primary or secondary stand-
ard within the time prescribed,
"(2) the plan, or any portion thereof, submitted for such
State is determined by the Administrator not to be in ac-
cordance with the requirements of this section, or
"(3) the State fails, within 60 days after notification by
the Administrator or such longer period as he may prescribe,
tQ revise an implementation plan as required pursuant to a
provision of its plan referred to in subsection (a) (2) (H) .
If such State held no public hearing associated with respect to
such plan (or revision thereof), the Administrator shall provide
opportunity for such hearing within such State on any proposed
regulation. The Administrator shall, within six months after the
date required for submission of such plan (or revision thereof),
promulgate any such regulations unless, prior to such promulga-
tion, such State has adopted and submitted a plan (or revision)
which the Administrator determines to be in accordance with the
requirements of this section.
"(d) For purposes of this Act, an applicable implementation
plan is the implementation plan, or most recent revision thereof,
which. has been approved under subsection (a) or promulgated
under subsection (c) and which implements a national primary
or secondary ambient air quality standard in a State.
"(e) (1) Upon application of a Governor of a State at the time
of submission of any plan implementing a national ambient air
quality primary standard, the Administrator may (subject to
paragraph (2» extend the three-year period referred to in sub-
section (a) (2) (A) (i) for not more than two years for an air
quality control region if after review of such plan the Adminis-
trator determines that-
"(A) one or more emission sources (or classes of moving
sources) are unable to comply with the requirements of such
plan which implement such primary standard because the
necessary technology or other alternatives are not available
or will not be available soon enough to permit compliance
within such three-year period, and
" (B) the State has considered and applied as a part of its
plan reasonably available alternative means of attaining such
primary standard and has justifiably concluded that attain-
ment of such primary standard within the three years cannot
be achieved.
"(2) The Administrator may grant an extension under para-

-------
14
graph (1) only if he determines that the State plan provides for-
"(A) application of the requirements of the plan which
implement such primary standard to all emission sources in
such region other than the sources (or classes) described in
paragraph (1) (A) within the three-year period, and
"(B) such interim measures of control of the sources (or
classes) described in paragraph (1) (A) as the Adminis-
trator determines to be reasonable under the circumstances.
"(f) (1) Prior to the date on which any stationary source or
class of moving sources is required to comply with any require-
ment of an applicable implementation plan the Governor of the
State to which such plan applies may apply to the Adminis-
trator to postpone the applicability of such requirement to such
source (or class) for not more than one year. If the Administrator
determines that-
"(A) good faith efforts have been made to .comply with
such requirement before such date,
"(B) such source (or class) is unable to comply with such
requirement because the necessary technology or other alter-
native methods of control are not available or have not been
available for a sufficient period of time,
"(C) any available alternative operating procedures and
interim control measures have reduced or will reduce the
impact of such source on public health, and
"(D) the continued operation of such source is essential
to national security or to the public health or welfare,
then the Administrator shall grant a postponement of such
requirement.
"(2) (A) Any determination under paragraph (1) shall (i) be
made on the record after notice to interested persons and oppor-
tunity for hearing, (ii) be based upon a fair evaluation of the
entire record at such hearing, and (iii) include a statement set-
ting forth in detail the findings and conclusions upon which the
determination is based.
"(B) Any determination made pursuant to this paragraph shall
be subject to judicial review by the United States Court of Appeals
for the circuit which includes such State upon the filing in such
court within 30 days from the date of such decision of a petition
by any interested person praying that the decision be modified or
set aside in whole or in part. A copy of the petition shall forthwith
be sent by registered or certified mail to the Administrator and
thereupon the Administrator shall certify and file in such court
the record upon which the final decision complained of was issued,
as provided in section 2112 of title 28, United States Code. Upon
the filing of such petition the court shall have jurisdiction to affirm
or set aside the determination complained of in whole or in part.
The findings of the Administrator with respect to questions of fact
(including each determination made under subparagraphs (A),
(B), (C), and (D) of paragraph (1» shall be sustained if based
upon a fair evaluation of the entire record at such hearing.
"(C) Proceedings before the court under this paragraph shall
take precedence over all the other causes of action on the docket

-------
15
and shall be assigned for hearing and decision at the earliest prac-
ticable date and expedited in every way.
"(D) Section 307 (a) (relating to subpenas) shall be applicable
to any proceeding under this subsection.
STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES
"SEC. 111. (a) For purposes of this section:
" (1) The term 'standard of performance' means a standard
for emissions of air pollutants which reflects the degree of
emission limitation achievable through the application of the
best system of emission reduction which (taking into account
the cost of achieving such reduction) the Administrator de-
termines has been adequately demonstrated.
"(2) The term 'new source' means any stationary source,
the construction or modification of which is commenced after
the publication of regulations (or, if earlier, proposed regu-
lations) prescribing a standard of performance under this
section which will be applicable to such source.
"(3) The term 'stationary source' means any building,
structure, facility, or installation which emits or may emit
any air pollutant.
" ( 4) The term 'modification' means any physical change in,
or change in the method of operation of, a stationary source
which increases the amount of any air pollutant emitted by
such source or which results in the emission of any air pollu-
tant not previously emitted.
"(5) The term 'owner or operator' means any person who
owns, leases, operates, controls, or supervises a stationary
source.
"(6) The term 'existing source' means any stationary
source other than a new source.
"(b) (1) (A) The Administrator shall, within 90 days after the
date of enactment of the Clean Air Amendments of 1970, publish
(and from time to time thereafter shall revise) a list of categories
of stationary sources. He shall include a category of sources in
such list if he determines it may contribute significantly to air
pollution which causes or contributes to the endangerment of
public health or welfare.
"(B) Within 120 days after the inclusion of a category of station-
ary sources in a list under subparagraph (A), the Administrator
shall publish proposed regulations, establishing Federal standards
of performance for new sources within such category. The Admin-
istrator shall afford interested persons an opportunity for written
comment on such proposed regulations. After considering such
comments, he shall promulgate, within 90 days after such publica-
tion, such standards with such modifications as he deems appro-
priate. The Administrator may, from time to time, revise such
standards following the procedure required by this subsection for
promulgation of such standards. Standards of performance or
revisions thereof shall become effective upon promulgation.

-------
16
"(2) The Administrator may distinguish among classes, types,
and sizes within categories of new sources for the purpose of es-
tablishing such standards.
"(3) The Administrator shall, from time to time, issue infor-
mation on pollution control techniques for categories of new
sources and air pollutants subject to the provisions of this section.
" ( 4) The provisions of this section shall apply to any new
source owned or operated by the United States.
" (c) (1) Each State may develop and submit to the Adminis-
trator a procedure for implementing and enforcing standards of
performance for new sources located in such State. If the Admin-
istrator finds the State procedure is adequate, he shall delegate to
such State any authority he has under this Act to implement and
enforce such standards (except with respect to new sources owned
or operated by the United States).
"(2) Nothing in this subsection shall prohibit the Adminis-
trator from enforcing any applicable standard of performance
under this section.
"(d) (1) The Administrator shall prescribe regulations which
shall establish a procedure similar to that provided by section 110
under which each State shall submit to the Administrator a plan
which (A) establishes emission standards for any existing source
for any air pollutant (i) for whicn air quality 'criteria have not
been issued or which is not included on a list published under ssc-
tion 108 (a) or 112 (b) (1) (A) but (ii) to which a standard of per-
formance under subsection (b) would apply if such existing source
were a new source, and (B) provides for the implementation and
enforcement of such emission standards.
"(2) The Administrator shall have the same authority-
"(A) to prescribe a plan for a State in cases where the
State fails to submit a satisfactory plan as he would have
under section 110 (c) in the case of failure to submit an im-
plementation plan, and
" (B) to enforce the provisions of such plan in cases where
the State fails to enforce them as he would have under sec-
tions 113 and 114 with respect to an implementation plan.
"(e) After the effective date of standards of performance pro-
mulgated under this section, it shall be unlawful for any owner
or operator of any new source to operate such source in violation
of any standard of performance applicable to such source.

NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS
"SEC. 112. (a) For purposes of this section-
"(1) The term 'hazardous air pollutant' means an air pollu-
tant to which no ambient air quality standard is applicable
and which in the judgment of the Administrator may cause,
or contribute to, an increase in mortality or an increase in
serious irreversible, or incapacitating reversible, illness.
"(2) The term 'new source' means a stationary source the
construction or modification of which is commenced after the
Administrator proposes regulations under this section estab-

-------
17
lishing an emission standard which will be applicable to such
source.
"(3) The terms 'stationary source,' 'modification,' 'owner
or operator' and 'existing source' shall have the same mean-
ing as such terms have under section 111 (a).
"(b) (1) (A) The Administrator shall, within 90 days after the
date of enactment of the Clean Air Amendments of 1970, publish
(and shall from time to time thereafter revise) a list which in-
cludes each hazardous air pollutant for which he intends to estab-
lish an emission standard under this section.
"(B) Within 180 days after the inclusion of any air pollutant
in such list, the Administrator shall publish proposed regulations
establishing emission standards for such pollutant together with
a notice of a public hearing within thirty days. Not later than 180
days after such publication, the Administrator shall prescribe an
emission standard for such pollutant, unless he finds, on the basis
of information presented at such hearings, that such pollutant
clearly is not a hazardous air pollutant. The Administrator shall
establish any such standard at the level which in his judgment
provides an ample margin of safety to protect the public health
from such hazardous air pollutants.
" (C) Any emission standard established pursuant to this sec-
tioi~ shall become effective upon promulgation.
"(2) The Administrator shall, from time to time, issue informa-
tion on pollution control techniques for air pollutants subject to
the provisions of this section.
"(c) (1) After the effective date of any emission standard under
this section-
"(A) no person may construct any new source or modify
any existing source which, in the Administrator's judgment,
will emit an air pollutant to which such standard applies un-
less the Administrator finds that such source if properly
operated will not 'cause emissions in violation of such stand-
ard, and
"(B) no air pollutant to which such standard applies may
be emitted from any stationary source in violation of such
standard, except that in the case of an existing source-
"(i) such standard shall not apply until 90 days after its
effective date, and
"(ii) the Administrator may grant a waiver permitting
such source a period of up to two years after the effective
date of a standard to 'Comply with the standard, if he finds
that such period is necessary for the installation of contRols
and that steps will be taken during the period of the waiver
to assure that the health of persons will be protected from
imminent endangerment.
"(2) The President may exempt any stationary source from
compliance with paragraph (1) for a period of not more than two
years if he finds that the technology to implement such standards
is not available and the operation of such source is required for
reasons of national security. An exemption under this paragraph
may be extended for one or more additional periods, each period

-------
18
not to exceed two years. The Preside!lt shall make. a report to
Congress with respect to each exemptIon (or extensIOn thereof)
made under this paragraph.
"(d) (1) Each State may develop and submit to the Adminis-
trator a procedure for implementing and enforcing em.ission
standards for hazardous air pollutants for stationary sources lo-
cated in such State. If the Administrator finds the State procedure
is adequate, he shall delegate to such State any authority he has
under this Act to implement and enforce such standards (except
with respect to stationary sources owned or operated by the
United States).
"(2) Nothing in this subsection shall prohibit the Adminis-
trator from enforcing any applicable emission standard under
this section.
FEDERAL ENFORCEMENT
"SEC. 113. (a) (1) Whenever, on the basis of any information
available to him, the Administrator finds that any person is in
violation of any requirement of an applicable implementation
plan, the Administrator shall notify the person in violation of the
plan and the State in which the plan applies of such finding. If
such violation extends beyond the 30th day after the date of the
Administrator's notification, the Administrator may issue an
order requiring such person to comply with the requirements of
such plan or he may bring a civil action in accordance with
subsection (b).
"(2) Whenever, on the basis of information available to him,
the Administrator finds that violations of an applicable imple-
mentation plan are so widespread that such violations appear to
result from a failure of the State in which the plan applies to
enforce the plan effectively, he shall so notify the State. If the
Administrator finds such failure extends beyond the thirtieth day
after such notice, he shall give public notice of such finding, (A)dur-
ing the period beginning with such public notice and ending when
such State satisfies the Administrator that it will enforce such
plan (hereafter referred to in this section as 'period of Federally
assumed enforcement') (B) the Administrator may enforce any
requirement of such plan with respect to any person-
"(A) by issuing an order to comply with such requirement,
or
" (B) by bringing a civil action under subsection (b).
"(3) Whenever, on the basis of any information available to
him, the Administrator finds that any person is in violation of
section 111 (e) (relating to new source performance standards) or
112 (c) (relating to standards for hazardous emissions), or is in
violation of any requirement of section 114 (relating to inspec-
tions, etc.), he may issue an order requiring such person to comply
with such section or requirement, or he may bring a civil action.
in accordance with subsection (b).
" ( 4) An order issued under this subsection (other than an
order relating to a violation of section 112) shall not take effect

"SEC. 114. (a) For the purpose (i) of developing or assisting in
the development of any implementation plan under section 110 or
111 (d) any, standard of performance under section 111, or any
emissio~ standard under section 112;(ii) of determining whether
any person is in violation of any such standard or any requirement
of such a plan, or (iii) carrying out section 303-
"(1) the Administrator may require the owner or operator
of any emission source to (A) establish and maintain such
records, (B) make such reports, (C) install, use, and main-
tain such monitoring equipment or methods, (D) sample such
emissions (in accordance with such methods, at such loca-
tions, at such intervals, and in such manner as the Ad-
ministrator shall prescribe), and (E) provide such other
information, as he may reasonably require; and
"(2) the Administrator or his authorized representative,

ABATEMENT BY MEANS OF CONFERENCE PROCEDURE
IN CERTAIN CASES
"SEC. 115. (a) The pollution of the air in any State or States
which endangers the health or welfare of any persons and which
is covered by subsection (b) or (c) shall be subject to abatement
as provided in this section.
"(b) (1) Whenever requested by the Governor of any State, a
State air pollution control agency, or (with the concurrence of the
Governor and the State air pollution control agency for the State
in which the municipality is situated) the governing body of any
municipality, the Administrator shall, if such request refers to
air pollution which is alleged to endanger the health Of welfare of
persons in a State other than that in which the discharge or dis-
charges (causing or contributing to such pollution) originate,
give formal notification thereof to the air pollution control agency
of the municipality where such discharge or discharges originate,
to the air pollution control agency of the State in which such
municipality is located, and to the interstate air pollution control
agency, if any, in whose jurisdictional area such municipality is
located, and shall call promptly a conference of such agency or
agencies and of the air pollution control agencies of the munici-
palities which may be adversely affected by such pollution, and
the air pollution control agency, if any, of each State, or for each
area, in which any such municipality is located.
" (2) Whenever requested by the Governor of any State, a State
air pollution control agency, or (with the concurrence of the Gov-
ernor and the State air pollution control agency for the State in
which the municipality is situated) the governing body of any
municipality, the Administrator shaH, if such request refers to
alleged air pollution which is endangering the health or welfare
of persons only in the State in which the discharge. or discharges
(causing or contributing to such pollution) originate and if a
municipality affected by such air pollution, or the municipality in
which such pollution originates, has either made or concurred in
such request, give formal notification thereof to the State air pol-
lution control agency, to the air pollution control agencies of the
municipality where such discharge or discharges originate, and of
the municipality or municipalities alleged to be adversely affected
thereby, and to any interstate air pollution control agency, whose
jurisdictional area includes any such municipality and shan
promptly can a conference of such agency or agencies, unless in
the judgment of the Administrator, the effect of such pollution is
not of such significance as to warrant exercise of Federal jurisdic-
tion under this section.
"(3) The Administrator may, after consultation with State
officials of an affected States, also can such a conference whenever,

-------
22
on the basis of reports, surveys, or studies, he has reason to be-
lieve that any pollution referred to in subsection (a) is .occurring
and is endangering the health and welfare of persons In a State
other than that in which the discharge or discharges originate.
The Administrator shall invite the cooperation of any municipal,
State or interstate air pollution control agencies having jurisdic-
tion in the affected area on any surveys or studies forming the
basis of conference action.
"(4) A conference may not be called under this subsection with
respect to an air pollutant for which (at the time the conference
is called) a national primary or secondary ambient air quality
standard is in effect under section 109.
"(c) Whenever the Administrator, upon receipt of reports, sur-
veys, or studies from any duly constituted international agency,
has reason to believe that any pollution referred to in subsection
(a) which endangers the health or welfare of persons in a foreign
country is occurring, or whenever the S"ecretary of State requests
him to do so with respect to such pollution which the Secretary of
State alleges is of such a nature, the Administrator shall give
formal notification thereof to the air pollution control agency of
the municipality where such discharge or discharges originate, to
the air pollution control agency of the State in which such munici-
pality is located, and to the interstate air pollution control agency,
if any, in the jurisdictional area of which such municipality is
located, and shall call promptly a conference of such agency or
agencies. The Administrator shall invite the foreign country
which may be adversely affected by the pollution to attend and
participate in the conference, and the representative of such coun-
try shall, for the purpose of the conference and any further pro-
ceeding resulting from such conference, have all the rights of a
State air pollution control agency. This subsection shall apply only
to a foreign country which the Administrator determines has
given the United States essentially the same rights with respect
to the prevention or control of air pollution occurring in that
country as is given that country by this subsection.
"(d) (1) The agencies called to attend any conference under this
section may bring such" persons as they desire to the conference.
The Administrator shall deliver to such agencies and make avail-
able to other interested parties, at least thirty days prior to any
such conference, a Federal report with respect to the matters be-
fore the conference, including data and conclusions or findings
(if any) ; and shall give at least thirty days' prior notice of the
conference date to any such agency, and to the public by publica-
tion on at least three different days in a newspaper or newspapers
of general -circulation in the area. The chairman of the conference
shall give interested parties an opportunity to present their views
to the conference with respect to such Federal report, conclusions
or findings (if any), and other pertinent information. The Ad-
ministrator shall provide that a transcript be maintained of the
proceedings of the conference and that a copy of such transcript
be made available on request of any participant in the conference
at the expense of such participant.

-------
23
"(2) Following this conference, the Administrator shall prepare
and forward to all air pollution 'control agencies attending the
conference a summary of conference discussions including (A)
occurrence of air pollution subject to abatement under this Act;
(B) adequacy of measures taken toward abatement of the pollu-
tion; and (C) nature of delays, if any, being encountered in abat-
ing the pollution.
"(e) If the Administrator believes, upon the conclusion of the
conference or thereafter, that 'effective progress toward abatement
of such pollution is not being made and that the health or welfare
of any persons is being endangered, he shall recomm'end to the ap-
propriate State, interstate, or municipal air pollution control
agency (or to all such agencies) that the necessary remedial ac-
tion be taken. The Administrator shall allow at least six months
from the date he makes such recommendations for the taking of
such recommended action.
"(f) (1) If, at the conclusion of the period 80 allowed, such re-
medial action or other action which in the judgment of the Ad-
ministrator is reasonably calculated to secure abatement of such
pollution has not been taken, the Administrator shall call a public
hearing, to be held in or near one or more of the places where the
discharge or discharges causing or contributing to such pollution
originated, before a hearing board of five or more persons ap-
pointed by the Administrator. Each State in which any discharge
causing or contributing to such pollution originates and each State
claiming to be adversely affected by such pollution shall be given
an opportunity to select one member of such hearing board and
each Federal department, agency, or instrumentality having a
substantial interest in the subj ect matter as determined by the
Administrator shall be given an opportunity to select one member
of such hearing board, and one member shall be a representative
of the appropriate interstate air pollution agency if one exists,
and not less than a majority of such hearing board shall be per-
sons other than officers or employees of the Environmental Pro-
tection Agency. At least three weeks' prior notice of such hearing
shall be given to the State, interstate, and municipal air pollution
control agencies called to attend such hearing and to the alleged
polluter or polluters. All interested parties shall be given a reason-
able opportunity to present evidence to such hearing board.
"(2) On the basis of evidence presented at such hearing, the
hearing board shall make findings as to whether pollution referred
to in subsection (a) is occurring and whether effective progress
toward abatement thereof is being made. If the hearing board
finds such pollution is occurring and effective progress toward
abatement thereof is not being made it shall make recommenda-
tions to the Administrator concerning the measures, if any, which
it finds to be'reasonable and suitable to secure abatement of such
pollution.
"(3) The Administrator shall send such findings and recom-
mendations to the person or persons discharging any matter caus-
ing or contributing to such pollution; to air pollution control
agencies of the State or States and of the municipality or munici-

-------
24
palities where such discharge or discharges ori~in~te.; ~nd to any
interstate air pollution control agency whose JurIsdIctIonal area
includes any such municipality, together with a notice specifying
a reasonable time (not less than six months) to secure abatement
of such pollution.
"(g) If action reasonably calculated to secure abatement of the
pollution within the time specified in the notice following the
public hearing is not taken the Administrator-
"(1) in the case of pollution of air which is endangering the
health or welfare of persons (A) in a State other than that
in which the discharge or discharges (causing or contributing
to such pollution) originate, or (B) in a foreign country
which has participated in a 'conference called under subsec-
tion (c) of this section and in all proceedings under this
section resulting from such conference, may request the At-
torney General to bring a suit on behalf of the United States
in the appropriate United States district court to secure
abatement of the pollution;
"(2) in the case of pollution of air which is endangering
the health or welfare of persons only in the State in which
the discharge or discharges (causing or contributing to such
pollution) originate, at the request of the Governor of such
State, shall provide such technical and other assistance as in
his judgment is necessary to assist the State in judicial pro-
ceedings to secure abatement of the pollution under State or
local law or, at the request of the Governor of such State,
shall request the Attorney General to bring suit on behalf of
the United States in the appropriate United States district
court to secure abatement of the pollution.
"(h) The court shall receive in evidence in any suit brought in
a United States court under subsection (g) of this section a tran-
script of the proceedings before the board and a copy of the
board's recommendations and shall receive such further evidence
as the court in its discretion deems proper. The court, giving due
consideration to the practicability of complying with such stand-
ards as may be applicable and to the physical and economic feasi-
bility of securing abatement of any pollution proved, shall have
jurisdiction to enter such judgment, and orders enforcing such
judg;nent, as the public interest and the equities of the case may
requIre.
"(i) Members of any hearing board appointed pursuant to sub-
section (f) who are not regular full-time officers or employees of
the United States shall, while participating in the hearing con-
ducted by such board or otherwise engaged on the work of such
board, he entitled to receive compensation at a rate fixed by the
Administration, but not exceeding $100 per diem, including trav-
eltime, and while away from their homes or regular places of
business they may be allowed travel expenses, including per diem
in lieu of subsistence, as authorized by law (5 D.S.C. 73b-2) for
persons in the Government service employed intermittently.
" (j) (1) In connection with any conference called under this
section, the Administrator is authorized to require any person

-------
25
whose activities result in the emission of air pollutants causing or
contributing to air pollution to file with him, in such form as he
may prescribe, a report, based on existing data, furnishing to the
Administrator such information as may reasonably be required
as to th~ character, kind, and quantity of pollutants discharged
and the use of devices or other means to prevent or reduce the
emission of pollutants by the person filing such a report. After a
conference has been held with respect to any such pollution the
Administrator shall require such reports from the person whose
activities result in such pollution only to the extent recommended
by such conference. Such report shall be made under oath or
otherwise, as the Administrator may prescribe, and shall be filed
with the Administrator within such reasonable period as the Ad-
ministrator may prescribe, unless additional time be granted by
the Administrator. No person shall be required in such report to
divulge trade secrets or secret processes and all information re-
ported shall be considered confidential for the purposes of section
19;05 of title 18 of the United States Code.
"(2) If any person required to file any report under this sub-
section shall fail to do so within the time fixed by the Adminis-
trator for filing the same, and such failure shall continue for
thirty days after notice of such default, such person shall forfeit
to the United States the sum of $100 for each and every day of
the continuance of such failure, which forfeiture shall be payable
into the Treasury of the United States, and shall be recoverable
in a civil suit in the name of the United States brought in the dis-
trict where such person has his principal office or in any district
in which he does business: Provided, that the Administrator may
upon application therefore remit or mitigate any forfeiture pro-
vided for under this subsection and he shall have authority to
determine the facts upon all such applications.
"(3) It shall be the duty of the various United States attorneys,
under the direction of the Attorney General of the United States,
to prosecute for the recovery of such forfeitures.
"(k) No order or judgm'ent under this section, or settlement,
compromise, or agreement respecting any action under this sec-
tion (whether or not entered or made before the date of 'enactment
of the Clean Air Amendments of 1970) shall relieve any person of
any obligation to comply with any requirement of an applicable
implementation plan, or with any standard prescribed under sec-
tion 111 or 112.
RETENTION OF STATE AUTHORITY
"SEC. 116. Except as otherwise provided in sections 209,
211 (c) (4), and 233 (preempting certain State regulation of mov-,
ing sources) nothing in this Act shall preclude or deny the right
of any State or political subdivision thereof to adopt or enforce
(1) any standard or limitation respecting emissions of air pollu-
tants or (2) any requirement respecting control or abatement of
air pollution; except that if an 'emission standard or limitation is
in effect under an applicable implementation plan or under section

-------
26
111 or 112 such State or political subdivision may not adopt or

executive, legislative, and judicial branches of the Federal Gov-
ernment (1) having jurisdiction over any property or facility, or
(2) engaged in any activity resulting, or which may result, in the
discharge of air pollutants, shall comply with Federal, State, in-
terstate, and local requirements respecting control and abatement
of air pollution to the same extent that any person is subject t,o
such requirements. The President may exempt any emission
source of any department, agency, or instrumentality in the execu-
tive branch from compliance with such a requirement if he deter-
mines it to be in the paramount interest of the United States to do
so, except that no exemption may be granted from section 111,
and an exemption from section 112 may be granted only in accord-
ance with section 112 (c). No such exemption shall be granted due
to lack of appropriation unless the President shall have specifically
requested such appropriation as a part of the budgetary process
and the Congress shall have failed to make available such re-
quested appropriation. Any exemption shall be for a period not in
excess of one year, but additional exemptions may be granted for
periods Inot to exceed one .year upon the President's making a
new determination. The President shall report each January to
the Congress all exemptions from the requirements of this section

TITLE II-EMISSION STANDARDS
FOR MOVING SOURCES
SHORT TITLE
"SEC. 201. This title may be cited as the 'National Emission
Standards Act.'
P ART A-MOTOR VEHICLE EMISSION
AND FUEL STANDARDS
ESTABLISHMENT OF STANDARDS
"SEC. 202. (a) Except as otherwise provided in subsection (b)-
"(1) The Administrator shall by regulation pres'cribe (and
from time to time revise) in accordance with the provisions
of this section, standards applicable to the emission of any air
pollutant from any class or classes of new motor vehicles or
new motor vehicle engines, which in his judgment causes or
contributes to, or is likely to cause or to contribute to, air
pollution which endangers the public health or welfare. Such
standards shall be applicable to such vehicles and engines for
their useful life (as determined under subsection' (d»,
whether such vehicles and engines are designed as complete
systems or incorporate devices to prevent or control such
pollution.
"(2) Any regulation prescribed under this subsection (and
any revision thereof) shall take effect after such period as
the Administrator finds necessary to permit the development
and application of the requisite technology, giving appropri-
ate consideration to the cost of compliance within such period.
"(b) (1) (A) The regulations under subsection (a) applicable
to emissions of carbon monoxide and hydrocarbons from light
duty vehicles and engines n1anufactured during or after model
year 1975 shall contain standards which require a reduction of at
least 90 per centum from emissions of carbon monoxide and hy-
drocarbons allowable under the standards under this section ap-
plicable to light duty vehicles and engines manufactured in model
year 1970.
"(B) The regulations under subsection (a) applicable to emis-
sions of oxides of nitrogen from light duty vehicles and engines
manufactured during or after model year 1976 shall contain
standards which require a reduction of at least 90 per centum
from the average of emissions of oxides of nitrogen actually
measured from light duty vehicles manufactured during model
year 1971 which are not subject to any Federal or State emission
standard for oxides of nitrogen. Such average of emissions shall
be determined by the Administrator on the basis of measurements
made by him.
"(2) Emission standards under paragraph (1), and measure-
ment techniques on which such standards are based (if not pro-

-------
29
mulgated prior to the date of enactment of the Clean Air Act
Amendments of 1970), shall be prescribed by regulation within
180 days after such date.
" (3) For purposes of this part-
"(A) (i) The term 'model year' with reference to any spe-
cific calendar year means the manufacturer's annual produc-
tion period (as determined by the Administrator) which
includes January 1 of such 'Calendar year. If the manufacturer
has no annual production period, the term 'model year' shall
mean the calendar year.
"(ii) For the purpose of assuring that vehicles and engines
manufactured before the beginning of a model year were not
manufactured for purposes of circumventing the effective
date of a standard required to be prescribed by subsection
(b), the Administrator may pres'Cribe regulations defining
'model year' otherwise than as provided'in clause (i).
"(B) The term 'light duty vehicles and engines' means new
light duty motor vehicles and new light duty motor vehicle
engines, as determined under regulations of the
Administrator.
"( 4) On July 1 of 1971, and of each year thereafter, the Admin-
istrator shall report to the Congress with respect to the develop-
ment of systems necessary to implement the emission standards
established pursuant to this section. Such reports shall include in-
formation regarding the continuing effects of such air pollutants
subj ect to standards under this section on the public health and
welfare, the extent and progress of efforts being made to develop
the necessary systems, the costs associated with development and
application of such systems, and following such hearings. as he
may deem advisable, any recommendations for additionalcongres-
sional action necessary to achieve the purposes of this Act. In
gathering information for the purposes of this paragraph and in
connection with any hearing, the provisions of section 307 (a)
(relating to subpenas) shall apply.
"(5) (A) At any time after January 1, 1972, any manufacturer
may file with the Administrator an application requesting the sus-
pension for one year only; of the effective date of any emission
standard required by paragraph (1) (A) with respect to such
manufacturer. The Administrator shall make his determination
with respect to any such application within 60 days. If he deter-
mines, in accordance with the provisions of this subsection, that
such suspension should be granted, he shall simultaneously with
such determination, prescribe by regulation, interim emission
standards which shall apply (in lieu of the standards required to
be prescribed, by paragraph (1) (A» to emissions of carbon
monoxide or hydrocarbons (or both) from such vehicles and en-
gines manufactured during model year 1975.
"(B) At any time after January 1, 1973, any manufacturer may
file with the Administrator an application requesting the suspen'-
sion, for one year only, of the effective date of any emission stand-
ard required by paragraph (1) (B) . with. respect to such
manufacturer. The Administrator shall make his determination

-------
30
with respect to any such application within 60 days. If he deter-
mines, in accordance with the provisions of this subsection, that
such suspension should be granted, he shall simultaneously, with
such determination, prescribe by regulation~ interim emission
standards which shall apply (in lieu of the standards required to
be prescribed by paragraph (1) (B» to emissions of oxides of
nitrogen from such vehicles and engines manufactured during
model year 1976.
"(C) Any interim standards prescribed under this paragraph
shall reflect the greatest degree of emission control which is
achievable by application of technology which the Administrator
determines is available, giving appropriate 'consideration to the
cost of applying such technology within the period of time avail-
able to manufacturers.
"(D) Within 60 days after receipt of the application for any
such suspension, and after public hearing, the Administrator shall
issue a decision granting or refusing such suspension. The Admin-
istrator shall grant such suspension only if he determines that (i)
such suspension is essential to the public interest or the public
health and welfare of the United States; (ii) all good faith efforts
have been made to meet the standards established by this subsec-
tion; (iii) the applicant has established that effective control tech-
nology, processes, operating methods, or other alternatives are not
available or have not been available for a sufficient period of time
to achieve compliance prior to the effective date of such standards,
and (iv) the study and investigation of the National Academy of
Sciences conducted pursuant to subsection (c) and other informa-
tion available to him has not indicated that technology, processes,
or other alternatives are available to meet such standards.
"(E) Nothing in this paragraph shall extend the effective date
of any emission standard required to be prescribed under this sub-
section for more than one year.
"(c) (1) The Administrator shall undertake to enter into ap-
propriate arrangements with the National Academy of Sciences
to conduct a comprehensive study and investigation of the tech-
nological feasibility of meeting the emissions standards required
to be prescribed by the Administrator by subsection (b) of this
section.
"(2) Of the funds authorized to be appropriated to the Admin-
istrator by this Act, such amounts as are required shall be avail-
able to carry out the study and investigation authorized by
paragraph (1) of this subsection.
"(3) In entering into any arrangement with the National
Academy of Sciences for conducting the study and investigation
authorized by paragraph (1) of this subsection, the Administrator
shall request the National Academy of Sciences to submit semi-
annual reports on the progress. of its study and investigation to
the Administrator and the Congress, beginning not later than
July 1, 1971, and continuing until such study and investigation is
completed.
" ( 4) The Administrator shall furnish to such Academy at its
request any information which the Academy deems necessary for

-------
31
the purpose of conducting the investigation and study authorized
by paragraph (1) of this subsection. For the purpose of furnish-
ing such information, the Administrator may use any authority
he has under this Act (A) to obtain information from any person,
and (B) to require such person- to conduct such tests, keep such
records, and make such reports respecting research or other ac-
tivities conducted by such person as may be reasonably necessary
to carry out this subsection:
" (d) The Administrator shall prescribe regulations under
which the useful life of vehicles and engines shall be determined
for purposes of subsection (a) (1) of this section and section 207.
Such regulations shall provide that useful life shall-
"(1) in the case of light duty vehicles and light duty
vehicle engines, be a period of use of five years or of fifty
thousand miles (or the equivalent), whichever first occurs;
and
"(2) in the case of any other motor vehicle or motor vehicle
engine, be a period of use set forth in paragraph (1) unless
the Administrator determines that a period of use of greater
duration or mileage is appropriate.
" (e) In the event a new power source or propulsion system for
new motor vehicles or new motor vehicle engines is submitted for
'certification pursuant to section 206 (a), the Administrator may
postpone certification until he has prescribed standards for any
air pollutants emitted by such vehicle or engine which cause or
contribute to, or are likely to cause or contribute to, air pollution
which endangers the public health or welfare but for which stand-
ards have not been prescribed under subsection (a).
PROHIBITED ACTS

MOTOR VEHICLE AND MOTOR VEHICLE ENGINE COMPLIANCE
TESTING AND CERTIFICATION
"SEC. 206. (a) (1) The Administrator shall test, or require to
be tested in such manner as he deems appropriate, any new motor
vehicle or new motor vehicle engine submitted by a manufacturer
to determine whether such vehicle or engine conforms with the
regulations prescribed under section 202 of this Act.. If such ve-
hicle or engine conforms to such regulations, the Administrator
shall issue a certificate of conformity upon such terms, and for
such period (not in excess of one year), as he may prescribe.
" (2) The Administrator shall test any emission control system
incorporated in a motor vehicle or motor vehicle engine submitted
to him by any person, in order to determine whether such system
enables such vehicle or engine to conform to the standards re-
quired to be prescribed under section 202 (b) of this Act. If the
Administrator finds on the basis of such tests that such vehicle or
engine conforms to such standards, the Administrator shall issue
a verification of compliance with emission standards for such
system when incorporated in vehicles of a class of which the
tested vehicle is representative. He shall inform manufacturers
and the National Academy of Sciences, and make available to the
public, the results of such tests. Tests under this paragraph shall

-------
34
be conducted under such terms and conditions (including require-
ments for preliminary testing by qualified independent labora-
tories) as the Administrator may prescribe by regulations.
"(b) (1) In order to determine whether new motor vehicles or
new motor vehicle engines being manufactured by a manufacturer
do in fact conform with the regulations with respect to which the
certificate of conformity was issued, the Administrator is author-
ized to test such vehicles or engines. Such tests may be conducted
by the Administrator directly or, in accordance with conditions
specified by the Administrator, by the manufacturer.
"(2) (A) (i) If, based on tests conducted under paragraph (1)
on a sample of new vehicles or engines covered by a 'certificate of
conformity, the Administrator determines that all or part of the
vehicles or engines so covered do not conform with the regulations
with respect to which the certificate of conformity was issued, he
may suspend or revoke such certificate in whole or in part, and
shall so notify the manufacturer. Such suspension or revocation
shall apply in the case of any new motor' vehicles or new motor
vehicle engines manufactured after the date of such notification
(or manufactured before such date if still in the hands of the
manufacturer), and shall apply until such time as the Adminis-
trator finds that vehicles and engines manufactured by the manu-
facturer do conform to such regulations. If, during any period of
suspension or revocation, the Administrator finds that a vehicle
or engine actually conforms to such regulations, he shall issue a
certificate of 'conformity applicable to such vehicle or engine.
"(ii) If, based on tests conducted under paragraph (1) on any
new vehicle or engine, the Administrator determines that such
vehicle or engine does not conform with such regulations, he may
suspend or revoke such certificate insofar as it applies to such
vehicle or engine until such time as he finds such vehicle or engine
actually so conforms with such regulations, and he shall so notify
the manufacturer.
"(B) (i) At the request of any manufacturer the Administrator
shall grant such manufacturer a hearing as to whether the tests
have been properly conducted or any sampling methods have been
p(foperly applied, and make a determination on the record with
respect to any suspension or revocation under subparagraph (A) ;
but suspension or revocation under subparagraph (A) shall not
be stayed by reason of such hearing.
"(ii) In any case of actual controversy as to the validity of any
determination under clause (i), the manufacturer may at any
time prior to the 60th day after such determination is made, file a
petition with the United States court of appeals for the circuit
wherein such manufacturer resides or has his principal place of
business for a judicial review of such determination. A copy of
the petition shall be forthwith transmitted by the clerk of the
court to the Administrator or other officer designated by him for
that purpose. The Administrator thereupon shall file in the court,
the record of the proceedings on which the Administrator based
his determination, as provided in section 2112 of title 28 of the
United States Code.

"(iii) If the petitioner applies to the court for leave to adduce
additional evidence, and shows to the satisfaction of the court that
such additional evidence is material and that there were reason-
able grounds for the failure to adduce such evidence in the pro-
ceeding before the Administrator, the court may order such
additional evidence (and evidence in rebuttal thereof) to be taken
before the Administrator, in such manner and upon such terms
and conditions as the 'Court may deem proper. The Administrator
may modify his findings as to the facts, or make new findings, by
reason of the additional evidence so taken and he shall file such
modified or new findings, and his recommendation, if any, for the
modification or setting aside of his original determination, with
the return of suCh additional evidence.
"(iv) Upon the filing of the petition referred to in clause (ii),
the court shall have jurisdiction to review the order in accordance
with chapter 7 of title 5, United States Code, and to grant appro-
priate relief as provided in such chapter.
"(c) For purpos'es of enforcement of this section, officers or
employees duly designated by the Administrator, upon presenting
appropriate credentials to the manufacturer or person in charge,
are authorized (1) to enter, at reasonable times, any plant or
other establishment of such manufacturers, for the purpose of
conducting tests of vehicles or engines in the hands of the manu-
facturer, or (2) to inspect at reasonable times, records, files,
papers, processes, controls, and facilities used by such manufac-
turer in conducting tests under regulations of the Administrator.
Each such inspection shall be commenced and completed with
reasonable promptness.
" (d) The Administrator shall by regulation establish methods
and procedures for making tests under this section.
" (e) The Administrator shall announce in the Federal Register
and make available to the public the results of his tests of any
motor vehicle or motor vehicle engine submitted by a manufac-
turer under subsection (a) as promptly as possible after the
enactment of the Clean Air Amendments of 1970 and at the be-
ginning of each model year which begins thereafter. Such results
shall be described in such nontechnical manner as will reasonably
disclose to prospective ultimate purchasers of new motor vehicles
and new motor vehicle engines the comparative performance of
the vehicles and engines tested in meeting the standards pre-
scribed under section 202 of this Act.
COMPLIANCE BY VEHICLES AND ENGINES IN ACTUAL USE

"SEC. 207. (a) Effective with respect to vehicles and engines
manufactured in model years beginning more than 60 days after
the date of the enactment of the Clean Air Act Amendments of
1970, the manufacturer of each new motor vehicle and new motor
vehicle engine shall warrant to the ultimate purchaser and each
subsequent purchaser that such vehicle or engine is (1) designed,
built, and equipped so as to conform at the time of sale with
applicable regulations under section 202, and (2) free from de-

-------
36
fects in materials and workmanship which cause such vehicle or
engine to fail to conform with applicable regulations for its useful
life (as determined under sec. 202 (d» .
"(b) If the Administrator determines that (i) there are avail-
able testing methods and procedures to ascertain whether, when
in actual use throughout its useful life (as determined under
section 202 (d) ), each vehicle and engine to which regulations
under section 202 apply complies with the emission standards of
such regulations, (ii) such methods and procedures are in accord-
ance with good engineering practices, and (iii) such methods and
procedures are reasonably capable of being correlated with tests
conducted under section 206 (a) (1), then-
"(1) he shall establish such methods and procedures by
regulation, and
"(2) at such time as he determines that inspection facilities
or equipment are available for purposes of carrying out test-
ing methods and procedures established under paragraph
(1), he shall prescribe regulations which shall require manu-
facturers to warrant the emission control device or system of
each new motor vehicle or new motor vehicle engine to which
a regulation under section 202 applies and which is manufac-
tured in a model year beginning after the Administrator first
prescribes warranty regulations under this paragraph (2).
The warranty under such regulations shall run to the ulti-
mate purchaser and each subsequent purchaser and shall pro-
vide that if-
"(A) the vehicle or engine is maintained and operated
in accordance with instructions under subsection (c) (3),
"(B) it fails to conform at any time during its useful
life (as determined under section 202 (d» to the regu-
lations prescribed under section 202, and
" (C) such nonconformity results in the ultimate pur-
chaser (or any subsequent purchaser) of such vehicle or
engine having to, bear any penalty or other sanction (in-
cluding the denial of the right to use such vehicle or
engine) under State or Federal law,
then such manufacturer shall remedy such nonconformity
under such warranty with the cost thereof to be borne by the
manufacturer.
" (c) Effective with respect to vehicles and engines manufac-
tured during model years beginning more tha,n 60 days after the
date of enactment of the Clean Air Amendments of 1970-
"(1) If the Administrator determines that a substantial
number of any class or category of vehicles or engines,
although properly maintained and used, do not conform to
the regulations prescribed under section 202, when in actual
use throughout their useful life (as determined under section
202 (d) ), he shall immediately notify the manufacturer
thereof of such nonconformity, and he shall require the manu-
facturer to submit a plan for remedying the nonconformity of
the vehicles or engines with respect to which such notification
is given. The plan shan provide that the nonconformity of any

-------
37
such vehicles or engines which are properly used and main-
tained will be remedied at the expense of the manufacturer.
If the manufacturer disagrees with such determination of
nonconformity and so advises the Administrator, the Admin-
istrator shall afford the manufacturer and other interested
persons an opportunity to pres'ent their views and evidence
in support thereof at a public hearing. Unless, as a result of
such hearing the Administrator withdraws such determina-
tion of nonconformity, he shall ,within 60 days after the com-
pletion of such hearing, order the manufacturer to provide
prompt notification of such nonconformity in accordance with
paragraph (2). .
"(2) Any notification required by paragraph (1) with re-
spect to any class or category of vehicles or engines shall be
given to dealers, ultimate purchasers, and subsequent pur-
chasers (if known) in such manner and containing such in-
formation as the Administrator may by regulations require.
"(3) The manufacturer shall furnish with each new motor
vehicle or motor vehicle engine such written instructions for
the maintenance and use of the vehicle or engine by the
ultimate purchaser as may be reasonable and necessary to
assure the proper functioning of emission control devices and
systems. In addition, the manufacturer shall indicate by
means of a label or tag permanently affixed to such vehicle or
engine that such vehicle or engine is covered by a certificate
of conformity issued for the purpose of assuring achievement
of emissions standards prescribed under section 202. Such
label or tag shall contain such other information relating to
control of motor vehicle emissions as the Administrator shall
prescribe by regulation.
" (d) Any cost obligation of any dealer incurred as a result of
any requirement imposed by subsection (a), (b), or (c) shall be
borne by the manufacturer. The transfer of any such cost obliga-
tion from a manufacturer to any dealer through franchise or other
agreement is prohibited.
" (e) If a manufacturer includes in any advertisement a state-
ment respecting the cost or value of emission control devices or
systems, such manufacturer shall set forth in such statement the
cost or value attributed to such devices or systems by the Secre-
tary of Labor (through the Bureau of Labor Statistics). The
Secretary of Labor, and his representatives, shall have the same
access for this purpose to the books, documents, papers, and rec-
ords of a manufacturer as the Comptroller General has to those of
a recipient of assistance for purposes of section 311.
"(f) Any inspection of a motor vehicle or a motor vehicle en-
gine for purposes of subsection (c) (1), after its sale to the ulti-
mate purchaser, shall be made only if the owner of such vehicle or
engine voluntarily permits such inspection to be made, except as
may be provided by any State or local inspection program.
(b) The amendments made by this section shall not apply to
vehicles or engines imported into the United States before the
sixtieth day after the date of enactment of this Act.

the Administrator may reasonably require to enable him to deter-
mine whether such manufacturer has acted or is acting in compli-
ance with this part and regulations thereunder and shall, upon
request of an officer or employee duly designated by the f\dmin-
istrator, permit such officer or employee at reasonable tImes to
have access to and copy such records.
" (b) Any records, reports or information obtained under sub-
section (a) shall be available to the public,except that upon a
showing satisfactory to the Administrator by any person that
records, reports, or information, or particular part thereof (other
than emission data), to which the Administrator has access under
this section if made public, would divulge methods or processes
entitled to protection as trade secrets of such person, the Admin-
istrator shall consider such record, report, or information or
particular portion thereof confidential in accordance with the
purposes of section 1905 of title 18 of the United States Code,
except that such record, report, or information may be disclosed
to other officers, 'employees, or authorized representatives of the
United States concerned with carrying out this Act or when rele-
vant in any proceeding under this Aet. Nothing in this section
shall authorize the withholding of information by the Administra-
tor or any officer or employee under his control, from the duly
authorized committees of the Congress.
STATE STANDARDS
"SEC. 209. (a) No State or any political subdivision thereof
shall adopt or attempt to enforce any standard relating to the
control of emissions from new motor vehicles or new motor vehicle
engines subject to this part. No State shall require certification,
inspection, or any other approval relating to the control of emis-
sions from any new motor vehicle or new motor vehicle engine as
condition precedent to the initial retail sale, titling (if any), or
registration of such motor vehicle, motor vehicle engine, or
equipment.
" (b) The Administrator shall, after notice and opportunity for
public hearing, waive application of this section to any State
which has adopted standards (other than crankcase emission
standards) for the control of emissions from new motor vehicles
or new motor vehicle engines prior to March 30, 1966, unless he
finds that such State does not require standards more stringent
than applicable Federal standards to meet compelling and extraor-
dinary conditions or that such State standards and accompanying
enforcement procedures are not consistent with section 202 (a) of
this part.
"(c) Nothing in this part shall preclude or deny to any State or
political subdivision thereof the right otherwise to control, regu-
late, or restrict the use, operation, or movement of registered or
licensed motor vehicles.

"SEC. 210. The Administrator is authorized to make grants to
appropriate State agencies in an amount up to two-thirds of the
cost of developing and maintaining effective vehicle emission de-
vices and systems inspection and emission testing and control
programs, except that-
"(1) no such grant shall be made for any part of any State
vehicle inspection program which does not directly relate to
the cost of the air pollution control aspects of such a program;
"(2) no such grant shall be made unless the Secretary of
Transportation has certified to the Administrator that such
program is consistent with any highway safety progran1 de-
veloped pursuant to section 402 of title 23 of the United
States Code; and
"(3) no such grant shall be made unless the program in-
cludes provisions designed to insure that emission control
devices and systems on vehicles in actual use have not been
discontinued or rendered inoperative.
REGULATION OF FUELS
"SEC. 211. (a) The Administrator may by regulation designate
any fuel or fuel additive and, after such date or gates as may be
prescribed by him, no manufacturer or processor of any such fuel
or additive may sell, offer for sale, or introduce into commerce
such fuel or additive unless the Administrator has registered such
fuel or additive in accordance with subsection (b) of this section.
- "(b) (1) For the purpose of registration of fuels and fuel addi-
tives, the Administrator shall require-
"(A) the manufacturer of any fuel to notify him as to the
commercial identifying name and manufacturer of any addi-
tive contained in such fuel; the range of concentration of any
additive in the fuel; and the purpose-in-use of any such addi-
tive;and
"(B) the manufacturer of any additive to notify him as to
the chemical composition of such additive.
"(2) For the purpose of registration of fuels and fuel additives,
the Administrator may also require the manufacturer of any fuel
or fuel additive-
"(A) to conduct tests to determine potential public health
effects of such fuel or additive (including, but not limited to,
carcinogenic, teratogenic, or mutagenic eff'ects), and
" (B) to furnish the description of any analytical technique
that can be used to detect and measure any additive in such
fuel, the recommended range of concentration of such addi-
tive, and the recommended purpose-in-use of such additive,
and such other information as is reasonable and necessary to
determine the emissions resulting from the use of the fuel or
additive contained in such fuel, the effect of such fuel or
additive on the emission control performance of any vehicle

-------
40
or vehicle engine, or the extent to which such emissions affect
the public health or welfare.
Tests under subparagraph (A) shall be conducted in conformity
with test procedures and protocols established by the Administra-
tor. The result of such tests shall not be considered confidential.
"(3) Upon compliance with the provision of this subsection,
including assurances that the Administrator will receive changes
in the information required, the Administrator shall register such
fuel or fuel additive.
" (c) (1) The Administrator may, from time to time on the basis
of information obtained under subsection (b) of this section or
other information available to him, by regulation, control or pro-
hibit the manufacture, introduction into commerce, offering for
sale, or sale of any fuel or fuel additive for use in a motor vehicle
or motor vehicle engine (A) if any emission products of such fuel
or fuel additive will endanger the public health or welfare, or (B)
if emission products of such fuel or fuel additive will impair to a
significant degree the performance of any emission control device
or system which is in general use, or which the Administrator
finds has been developed to a point where in a reasonable time it
would be in general use were such regulation to be promulgated.
"(2) (A) No fuel, class of fuels, or fuel additive may be con-
trolled or prohibited by the Administrator pursuant to clause (A)
of paragraph (1) except after consideration of all relevant medi-
cal and scientific evidence available to him, including consideration
of other technologically or economically feasible means of achiev-
ing emission standards under section 202.
" (B) No fuel or fuel additive may be controlled or prohibited by
the Administrator pursuant to clause (B) of paragraph (1)
except after consideration of available scientific and economic
data, including a cost benefit analysis comparing emission control
devices or systems which are or will be in general use and require
the proposed control or prohibition with emission control devices
or systems which are or will be in general use and do not require
the proposed control or prohibition. On request of a manufacturer
of motor vehicles, motor vehicle engines, fuels, or fuel additives
submitted within 10 days of notice of proposed rulemaking, the
Administrator shall hold a public hearing and publish findings
with respect to any matter he is required to consider under this
subparagraph. Such findings shall be published at the time of
promulgation of final regulations.
"(C) No fuel or fuel additive may be prohibited by the Admin-
istrator under paragraph (1) unless he finds, and publishes such
finding, that in his judgment such prohibition will not cause the
use of any other fuel or fuel additive which will produce emissions
which will endanger the public health or welfare to the same or
greater degree than the use of the fuel or fuel additive proposed
to be prohibited.
"(3) (A) For the purpose of obtaining evidence and data to carry
out paragraph (2), the Administrator may require the manufacturer
of any motor vehicle or motor vehicle engine to furnish any infor-
mation which has been developed concerning the emissions from

or attempt to enforce, for purposes of motor vehicle emission con-
trol, any control or prohibition respecting use of a fuel or fuel
additive in a motor vehicle or motor vehicle engine-
"(i) if the Administrator has found that no control or
prohibition under paragraph (1) is necessary and has pub-
lished his finding in the Federal Register, or
"(ii) if the Administrator has prescribed under paragraph
(1) a control or prohibition applicable to such fuel or fuel
additive, unless State prohibition or control is identical to
the prohibition or control prescribed by the Administrator.
"(B) Any State for which application of section 209 (a) has at
any time been waived under section 209 (b) may at any time
prescribe and enforce, for the purpose of motor vehicle 'emission
control, a control or prohibition respecting any fuel or fuel
additive.
"( C) A State may prescribe and enforce, for purposes of motor
vehicle emission 'Control, a control or prohibition respecting the
use of a fuel or fuel additive in a motor vehicle or motor vehicle
engine if an applicable implementation plan for such State under
section 110 so provides. The Administrator may approve such pro-
vision in an implementation plan, or promulgate an implementa-
tion plan containing such a provision, only if he finds that the
State control or prohibition is necessary to achieve the national
primary or secondary ambient air quality standard which the plan
implements.
"(d) Any person who violates subsection (a) or the regulations
prescribed under subsection (c) or who fails to furnish any in.;
formation required by the Administrator under subsection (b)
shall forfeit and pay to the United States a civil penalty of $10,000
for each and every day of the continuance of such violation, which
shall accrue to the United States and be recovered in a civil suit
in the name of the United States, brought in the district where
such person has his principal office or in any district in which he

substitute for any class or classes of vehicles presently being pur-
chased by the Federal Government for use by its agencies.
" (G) Immediately upon making any determination or decision
under subparagra.ph (F), the Administrator and the Board shall
each publish in the Federal Register notice of such determination

-------
44
or decision, including reasons therefor and in the case of the
Board, -any dissenting views. .
" (e) (1) Certified low-emission vehicles shall be acquIred by
purchase or lease by the Federal Gov.ernm.ent for use. br the Fed-
eral Government in lieu of other vehIcles If the AdmInIstrator of
General Services determines that such certified vehicles have pro-
curement costs which are no more than 150 per centum of the
retail price of the least expensive 'class or model of motor vehicle
for which they are certified substitutes.
"(2) In order to encourage development of inherently low-
polluting propulsion technology, the Board may, at its discretion,
raise the premium set forth in paragraph (1) of this subsection
to 200 per centum of the retail price of any class or model of
motor vehicle for which a 'certified low-emission vehicle is a certi-
fied substitute, if the Board determines that the certified low-
emission vehicle is powered by an inherently low-polluting propul-
sion system.
"(3) Data relied upon by the Board and the Administrator in
determining that a vehicle is a certified low-emission vehicle shall
be incorporated in any contract for the procurement of such
vehicle.
"(f) The procuring agency shall be required to purchase avail-
able certified low-emission vehicles which are eligible for purchase
to the extent they are available before purchasing any other
vehicles for which any low-emission vehicle is a certified substi-
tute. In making purchasing selections between competing eligible,
certified low-emission vehicles, the procuring agency shall give
priority to (1) any class or model which does not require exten-
sive periodic maintenance to retain its low-polluting qualities or
which does not require the use of fuels which are more expensive
than those of the classes or models of vehicles for which it is a
certified substitute; and (2) passenger vehicles other than buses.
"(g) For the purpose of procuring certified low-emission vehi-
cles any statutory price limitations shall be waived.
"(h) The Administrator shall, from time to time as the Board
deems appropriate, test the emissions from certified low-emission
vehicles purchased by the Federal Government. If at any time he
finds that the emission rates exceed the rates on which certifica-
tion under this section was based, the Administrator shall notify
the Board. Thereupon the Board shall give the supplier of such
vehicles written notice of this finding, issue public notice of it, and
give the supplier an opportunity to make necessary repairs, ad-
justments, or replacements. If no such repairs, adjustments, or
replacements are made within a period to be set by the Board,
the Board may order the supplier to show cause why the vehicle
involved should be eligible for recertification.
"(i) There are authorized to be appropriated for paying addi-
tional amounts for motor vehicles pursuant to, and for carrying
out the provisions of, this section, $5,000,000 for the fiscal year
ending June 30, 1971, and $25,000,000 for each of the two suc-
ceeding fiscal years.

mence a study and investigation of emissions of air pollutants
from aircraft in order to determine-

-------
46
"(A) the extent to which such emissions affect. air quality
in air quality control regions throughout the UnIted States,
and .
"(B) the technological feasibility of controlling such emIS-
sions.
"(2) Within 180 days after commencing such study and investi-
gation, the Administrator shall publish a r~po!t of such study an~
investigation and shall issue proposed emISSIOn standards applI-
cable to emissions of any air pollutant from any class or classes of
