Section 43646 Of Article 1. Device Certification From California Health And Safety Code >> Division 26. >> Part 5. >> Chapter 3. >> Article 1.
43646
. (a) The bureau, in consultation with the state board, may
develop, not later than 180 days from the operative date of this
section, a list of engine maintenance practices that are designed to
improve a motor vehicle's engine operating efficiency. The bureau
shall conduct any evaluations that it determines to be necessary to
identify the extent to which various maintenance practices could
reduce vehicle emissions, and the minimum periodic application of
each maintenance practice that is required to achieve the desired
improvement in engine operating efficiency. The bureau may contract
with private automotive testing services to carry out the
evaluations.
(b) The bureau shall make the list available to the public, and
shall specify therein the extent to which each maintenance practice
can be expected to reduce vehicle emissions, and how the application
of each practice could result in a reduction of the vehicle's smog
index.
(c) A motor vehicle owner who subjects his or her vehicle to
enhanced maintenance practices, as established by the bureau, may
submit the vehicle to an in-use emissions evaluation at a smog check
station to determine if excessive in-use emissions have been reduced.
If the vehicle is certified as having reduced its emissions relative
to its last in-use emissions evaluation, the Department of Motor
Vehicles shall adjust the smog index for the vehicle. Vehicles
receiving adjustments pursuant to this subdivision shall submit to
annual in-use emissions evaluations to maintain their adjusted smog
index. A failure to submit an annual in-use emissions evaluation to
the Department of Motor Vehicles shall result in the vehicle's smog
index being adjusted to its original level.
(d) This section shall become inoperative pursuant to Section 33
of the act adding this section or, in any case, five years from the
date determined pursuant to Section 32 of the act adding this
section, and on the January 1 following the date upon which this
section becomes inoperative, is repealed.
