HSC § 44251 Effective Sep 30, 1996Div. 26 · Part 5 · Ch. 8

Statute text

(a)The state board shall specify smog index numbers for new light-duty passenger vehicles and light-duty trucks with a gross vehicle weight up to 6,000 pounds to be sold in California. That smog index shall be based on certification data quantifying tailpipe and evaporative emissions of ozone precursor chemicals for classes of vehicles.

(b)For diesel fuel vehicles, the smog index shall be based on certification data quantifying tailpipe emissions of ozone precursor chemicals and particulate matter. Particulate emissions from diesel fuel vehicles certified to model year standards that did not include a particulate limit may be assumed to be equal to particulate emissions for model year 1985 diesel fuel vehicles.

(c)The state board shall specify the relative weight of emissions of ozone precursor chemicals and particulates in the smog index values for diesel vehicles. This weighting shall be based on the relative importance of each category of emissions to air quality problems in California.
