Section 43630 Of Article 1. Device Certification From California Health And Safety Code >> Division 26. >> Part 5. >> Chapter 3. >> Article 1.
43630
. (a) In addition to certifying devices which meet the
standards set forth in, or established pursuant to, Sections 43602
and 43610, the state board shall adopt standards for certifying
exhaust devices which achieve a reduction of the emission of
hydrocarbons, carbon monoxide, and oxides of nitrogen from the
exhaust of a motor vehicle substantially below the standards for any
two pollutants set forth in, or established pursuant to, Section
43602 or 43610.
If, however, an exhaust device is shown to substantially reduce
the emission of any two of the three pollutants, the state board may
certify such a device, so long as the installation of such device in
a motor vehicle does not increase the emission of the other pollutant
in excess of the emission of that pollutant by the vehicle in the
absence of such a device.
(b) Devices certified pursuant to this section may be certified
without regard to the provisions of subdivision (a) of Section 43604
or subdivision (a) of Section 43612.
(c) After one or more such devices are initially certified, no
device shall be certified pursuant to this section which is
substantially less effective than any device previously certified,
unless the state board determines, pursuant to a cost-benefit
analysis, that such less effective device is also substantially less
costly and therefore merits certification. Any subsequent
certification of a more effective device shall not affect the
certification of a previously certified device.
(d) The state board may permit the installation of a device
certified pursuant to this section in lieu of any certified motor
vehicle pollution control device which is required to be installed
pursuant to any other provision of state law, if the installation of
such device on that particular classification of motor vehicles
results in no greater emissions than if the required certified device
were operative over the life of the vehicle. The applicant shall be
responsible for proving compliance with this subdivision and with
other applicable criteria. Certificates of compliance shall be
required upon the installation of a device certified pursuant to this
section and installed pursuant to this subdivision, as if it were a
device required by any other provision of state law.
