(1)
Notwithstanding any other provision of this chapter, a vehicle manufacturer may
certify 1983 and later model vehicles to optional NOx standards except for
vehicles certifying to TLEV, LEV, or ULEV standards as follows:
(A) Passenger cars--0.7 g/mi-1983 through
1988 model years.
LDT, MDV 0-3999 pounds EIW--1.0 g/mi--1983 through 1987
model years.
LDT, MDV 0-3750 lbs. LVW--1.0 g/mi--1988 model
year.
(B) For the 1989 model
year, each manufacturer may certify no more than 50 percent of its projected
California model-year sales of passenger cars, light-duty trucks (0-3750 lbs.
LVW), and medium-duty vehicles (0-3750 lbs. LVW) to the optional NOx standard
as follows:
Passenger cars--0.7 g/mi
LDT, MDV 0-3750 lbs. LVW--1.0 g/mi
(C) 1989 through 1993 model-year passenger
cars weighing more than 5250 lbs. LVW may be certified to the 0.7 g/mi NOx
standard.
(D) For the 1990 through
1993 model years, a vehicle manufacturer may certify passenger cars, light-duty
trucks (0-3750 lbs. LVW), and medium-duty vehicles (0-3750 lbs. LVW) to the
optional 0.7 g/mi NOx standard subject to the following limitations:
For each model year, the total number of passenger cars
(0-5250 lbs. LVW) each manufacturer may certify at 0.7 g/mi NOx shall be
limited to a maximum of 10 percent of the total previous California model-year
sales of these vehicles.
For each model year, the total number of light-duty trucks
(0-3750 lbs. LVW) and medium-duty vehicles (0-3750 lbs. LVW) each manufacturer
may certify at 0.7 g/mi NOx shall be limited to a maximum of 15 percent of the
combined total previous California model-year sales of these vehicles.
For manufacturers certifying for the first time in
California, "previous California model-year sales" shall mean projected
California model-year sales.
(2) Notwithstanding any other provisions of
this chapter, a small volume manufacturer may certify 1989 and later model
vehicles to optional NOx standards except for vehicles certifying to TLEV, LEV,
or ULEV standards as follows:
(A) Passenger
cars--0.7 g/mi--1989 and 1990 model years.
LDT, MDV 0-3750 lbs. LVW--1.0 g/mi--1989 and 1990 model
years.
(B) For the 1991
model year, each small volume manufacturer may certify no more than 50 percent
of its projected California model-year sales of passenger cars, light-duty
trucks (0-3750 lbs. LVW), and medium-duty vehicles (0-3750 lbs. LVW) to the
optional NOx standards as follows:
Passenger cars--0.7 g/mi
LDT, MDV 0-3750 lbs. LVW--1.0 g/mi
(C) For the 1992 through 1995 model years,
each small volume manufacturer may certify passenger cars, light-duty trucks
(0-3750 lbs. LVW), and medium-duty vehicles (0-3750 lbs. LVW) to the optional
0.7 g/mi NOx standard subject to the following limitations:
For each model year, the total number of passenger cars
(0-5250 lbs. LVW) each manufacturer may certify at 0.7 g/mi NOx shall be
limited to a maximum of 10 percent of the total previous California model-year
sales of these vehicles.
For each model year, the total number of light-duty trucks
(0-3750 lbs. LVW) and medium-duty vehicles (0-3750 lbs. LVW) each manufacturer
may certify at 0.7 g/mi NOx shall be limited to a maximum of 15 percent of the
combined total previous California model-year sales of these vehicles.
For manufacturers certifying for the first time in
California, "previous California model-year sales" shall mean projected
California model-year sales.
(b) Testing of vehicles certified under this
section shall be conducted in accordance with the California Exhaust Emission
Test Procedures applicable to either 1981 through 1987 or 1988 and subsequent
model passenger cars, light-duty trucks, and medium-duty vehicles certified to
the primary California standards for 50,000 miles.
(c)
(1) If,
based on a review of information derived from a statistically valid and
representative sample of vehicles, the Executive Officer determines that a
substantial percentage of any class or category of vehicles certified under
this section exhibits, prior to 75,000 miles or 7 years, whichever occurs
first, an identifiable, systematic defect in a component listed in subsection
(2) which causes a significant increase in emissions above those exhibited by
vehicles free of such defects and of the same class or category and having the
same period of use and mileage, then the Executive Officer may invoke the
enforcement authority under Section
2109 to require remedial action by
the vehicle manufacturer. Such remedial action shall be limited to owner
notification and repair or replacement of the defective component. As used in
this section, the term "defect" shall not include failures which are the result
of abuse, neglect, or improper maintenance.
(2) Subsection (c)(1) shall apply to the
following components unless subject to allowable scheduled maintenance prior to
75,000 miles or 7 years, whichever occurs first:
I. Air and Fuel Metering System
A. Cold start enrichment
B. Heat riser valve and assembly
C. Controlled hot air
intake
II. Exhaust Gas
Recirculation (EGR) System
A. EGR valve and
control components, and carburetor spacer if applicable
III. Air Injection System
A. Air pump
B. Valves affecting distribution of
flow
C. Distribution manifold
including connection to exhaust manifold
IV. Catalyst or Thermal Reactor System
A. Catalytic converter and associated
mounting hardware and constricted fuel filler neck
B. Thermal reactor and lined or coated
exhaust manifolds
C. Exhaust
portliner and/or double walled exhaust pipe
V. Evaporative Emission Control System
A. Vapor storage canister
B. Vapor-liquid separator
VI. Miscellaneous Items Used in Above Systems
A. Vacuum, temperature, and time sensitive
valves and switches
B. Electronic
controls including computer or microprocessor and all input sensors except for
the exhaust gas oxygen sensor
(d) Nothing in this section shall be
construed as affecting in any way the manufacturer's 5 year/50,000 mile
emission control systems defect warranty obligations existing under present
statutes and regulations.
