(3) The cost of any part, device, or component of any
light-duty vehicle that is designed for emission control and
which in the instructions issued pursuant to subsection (c)(3) of
this section is scheduled for replacement during the useful life
of the vehicle in order to maintain compliance with regulations
under section 202 of this Act, the failure of which shall not
interfere with the normal performance of the vehicle, and the
expected retail price of which, including installation costs, is
greater than 2 percent of the suggested retail price of such
vehicle, shall be borne or reimbursed at the time of replacement
by the vehicle manufacturer and such replacement shall be
provided without cost to the ultimate purchaser, subsequent
purchaser, or dealer. The term "designed for emission control" as
used in the preceding sentence means a catalytic converter,
thermal reactor, or other component
installed on or in a vehicle for the sole or primary purpose of
reducing vehicle emissions (not including those vehicle
components which were in general use prior to model year 1968 and
the primary function of which is not related to emission
control).
(b) If the Administrator determines that (i) there are
available testing methods and procedures to ascertain whether,
when in actual use throughout its the warranty period (as
determined under subsection (i)), 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 accordance 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 testing
methods and procedures established under paragraph (1), he
shall prescribe regulations which shall require manufacturers
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 manufactured in a model
year beginning after the Administrator first prescribes
warranty regulations under this paragraph. The warranty under
such regulations shall run to the ultimate purchaser and each
subsequent purchaser and shall provide 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 its1 the
warranty period (as determined under subsection (i)) to the
regulations prescribed under section 202, and
(C) such nonconformity results in the ultimate purchaser
(or any subsequent purchaser) of such vehicle or engine
having to bear any penalty or other sanction (including 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 manufac-
turer. No such warranty shall be invalid on the basis of any
part used in the maintenance or repair of a vehicle or engine
if such part was certified as provided under subsection (a)(2).
[For purposes of the warranty under this subsection, for the
period after twenty-four months or twenty-four thousand miles
(whichever first occurs) the term "emission control device or
system" means a catalytic converter, thermal reactor, or other
component installed on or in a vehicle for the sole or primary
purpose of reducing vehicle emissions. Such terms shall not
include those vehicle components which were in general use
prior to model year 1968.]
(c) Effective with respect to vehicles and engines manufactured
during model years beginning more than 60 days after the date of
enactment of the Clean Air Amendments of 1970
(d) Retrofit Requirements.- Not later than 12 months after the
enactment of the Clean Air Act Amendments of 1990, the
Administrator shall promulgate regulations under section 202(a)
requiring that urban buses which-
(1) are operating in areas referred to in subparagraph (A)
of subsection (c)(2) (or subparagraph (C) of subsection
(c)(2) if the Administrator has taken action under that
subparagraph);
(2) were not subject to standards in effect under the
regulations under subsection (a); and
(3) have their engines replaced or rebuilt after January
1, 1995,
shall comply with an emissions standard or emissions control
technology requirement established by the Administrator in such
regulations. Such emissions standard or emissions control
technology requirement shall reflect the best retrofit technology
and maintenance practices reasonably achievable.
