Section 43101.5 Of Article 1. General Provisions From California Health And Safety Code >> Division 26. >> Part 5. >> Chapter 2. >> Article 1.
43101.5
. The emission standards adopted by the state board pursuant
to Section 43101 for the 1983 and later model-year motor vehicles
shall be limited by the following:
(a) For all gasoline-powered passenger vehicles prior to the 1986
model year, the state board shall not adopt primary standards for the
emission of oxides of nitrogen which are more stringent than 0.7
grams per vehicle mile, unless the state board by regulation also
provides for optional standards which are not more stringent, with
respect to each constituent, than 0.39 grams per vehicle mile for
nonmethane hydrocarbon, 7.0 grams per vehicle mile for carbon
monoxide, and 0.7 grams per vehicle mile for oxides of nitrogen. For
gasoline-powered light-duty vehicles and medium-duty vehicles prior
to the 1986 model year of less than 4,000 pounds unladen weight, the
state board shall not adopt primary standards for the emission of
oxides of nitrogen which are more stringent than 1.0 gram per vehicle
mile, unless the state board by regulation also provides for
optional standards which are not more stringent, with respect to each
constituent, than 0.39 grams per vehicle mile for nonmethane
hydrocarbon, 9.0 grams per vehicle mile for carbon monoxide, and 1.0
gram per vehicle mile for oxides of nitrogen. Any option may not
impose certification, warranty, or enforcement requirements of
greater duration or stringency than those set forth in the
regulations applicable to 1983 and later model years, as adopted or
amended by the state board on May 20, 1981.
(b) If the state board intends by regulation to eliminate for 1986
and later model-year vehicles the optional standards specified in
subdivision (a), the state board shall submit to the Legislature, not
later than January 15th of the year which is at least two calendar
years prior to the year in which production would commence of
vehicles subject to the new standard, a report with an estimate of
the air quality benefits of the more stringent standard, the
technological and economic feasibility of requiring the standard, and
the potential effects on fuel economy associated with the standard.
The state board shall consult with the Environmental Protection
Agency and motor vehicle and engine manufacturers prior to submitting
the air quality and fuel economy estimates.
