             b.  Low-emission vehicle (LEV).
             c.  Ultra-low-emission vehicle (ULEV).
             d.  Zero-emission vehicle (ZEV), or 
         230.2   A heavy-duty vehicle meeting either:
             a.  California Air Resources Board-certified low-emission 
                 standards, or
             b.  A heavy-duty vehicle powered by an engine
                 certified to one of the federal clean fuel fleet
                 emission standards for heavy-duty engines (40 CFR
                 Section 88.105-94). LEV (on California fuel),
                 ULEV, or ZEV standards (40 CFR Parts 86 and 88). 
                 The LEV standard is 3.5 g/bhp-hr NMHC+NOx for
                 certification on California diesel fuel.  The
                 ULEV standard is 2.5 g/bhp-hr NMHC+NOx, and the
                 ZEV standard is zero NMHC+NOx.  Heavy-duty
                 engines certified to the federal LEV (on
                 California fuel), ULEV, and ZEV standards are to
                 be considered as 3.5, 2.5, and zero g/bhp-hr NOx
                 engines, respectively, for the purpose of
                 calculating compliance with Rule 1003.
             c.  Reduced emission standards for NOx, or combined
                 hydrocarbons plus NOx,  may be adopted by the
                 federal Environmental Protection Agency or the
                 California Air Resources Board.  As used in this
                 Section, "reduced emission" means that the
                 numerical value of the reduced emission standard
                 is less than the numerical value of the highest
                 NOx standard otherwise applicable in the
                 Sacramento area to the engine and application
                 under consideration.

                 characteristics on its snapshot date typify that
                 fleet's characteristics during the entire reporting
                 year.

    234  SUBMITTAL DATE:  The annual deadline for submittal of a
         fleet inventory report to the Air Pollution Control
         Officer.  The submittal date shall be established by the
         Air Pollution Control Officer. 

    235  SUBMITTAL NOTICE:  A notice issued annually by the Air
         Pollution Control Officer to fleet operators specifying the
         submittal date.
