                                    SUMMARY


      Chevron U.S.A., Inc. requested an exemption from the prohibitions of

Vehicle Code (VC) Section 27156 for modifications for a fleet of 18 vehicles
used at the Richmond, California oil refinery.

      The requested modifications involve sealing or replacing various items in

the vehicle‘s electrical system to prevent combustible vapors from entering and

being ignited.

      The staff does not foresee any adverse emissions impact due to the

proposed modifications.   The staff, therefore, recommends exemption of the
modification from the prohibitions of VC Section 27156.

Evaluation of Chevron Oil Company‘s Request for Exemption from the Prohibitions
of Yehicle Code Section 27156 for Modifying Refinery Use Vehicles


I.    INTRODUCTION
      Chevron U.S.A., Inc. has requested the Air Resources Board to exempt a

fleet of 18 vehicles used at their Richmond, California ofl refinery from

the prohibitions of VC Section 27156.   The requested modifications involve

sealing or replacing various items in the vehicle‘s electrical system to

prevent combustible vapors from entering and being ignited.    Combustible

vapors commonly exist in the environment of an oil refinery.

II.   CONCLUSION
      All machineries used in hazardous environments are required to be made
safe during their operations.   The motor vehicle is no exception.   Chevron‘s
proposed modifications are designed to prevent combustible vapors from being

igni;ed when a vehicle is being operated.
      The addition of covers, seals, protective devices, etc., does not

affect the function of the vehicle‘s electrical system.   The replacement
ignition wires and Mallory UnilTite distributor are of equivalent quality {or

better) than the OEM parts.

      The removal of the distributor‘s vacuum advance, according to ARB‘s

recent surveillance testing, will not adversely affect the vehicle‘s exhaust

emissions.   However, the retard in total timing caused by the removal of the

vacuum advance will result in higher engine exhaust temperatures, which may

affect the catalytic converter‘s useful life.


III.   RECOMMENDATION
       The staff does not foresee any adverse emissions impact due to

Chevron‘s proposed modifications.      The staff believes that, even though the
exhaust gas temperature will be higher, there will be very Tittle change in

the catalyst‘s life due to the limited usage of these vehicles in the 3.5

square mile Chevron refinery.      The staff recommends that they be granted

exemption from the prohibitions of VC 27156 for the fleet of vehicles lTisted
in Attachment II and that Executive Order D—128 be adopted.

IV.    MODIFICATIONS DESCRIPTION
       Chevron‘s proposed modifications are found in Attachment 1.     The

purpose of the modifications is to prevent combustible vapors from being
ignited by the vehicle‘s electrical system.      The modifications involve

sealing of the vents in the starter motor, generator/alternator, voltage

regulator, switches, lTights, and auxiliary electrical systems.

Additionally, the ignition system is modified by one or more of the

following:

       1)      The OEM secondary ignition wires are replaced with a high

temperature silicon rubber type.
       i1i)    The Kettering ignition points are replaced with a solid state

ignition system.

       1i1) A new distributor cap with a safety retention strap is installed.
       iv)     The vacuum advance is removed and replaced with a sealed cover on

some models with OEM Kettering ignition systems.

       v)      A flame arrestor vent is installed in the distributor‘s body.

       vi)})   Certain late model Ford vehicles with Dura—Spark ignition

distributors are replaced with Mallory Unilite Systems since the Dura—Spark

systems could not be safely modified.


                                                             Attachment I



                             Necessary Engine Modifications

The purpose of the modifications is to minimize fire loss risks associated with the use of
the engines in restricted areas.

     Starter Motor

     The starter, starter motor switch, and solenoid are inspected to ensure there are no
     openings into which vapors could leak,. In those vehicles which had openings, one or
     more of the following modifications was made:

     a.    The starter motor was fitted with a tight—fitting cover band with a gasket to
           shield commutator arcing.

     b.    The starter motor switch was fitted with a tight—fitting cover, or the switch
           cover to the solencid was sealed with epoxy.

     c.    The starter solenoid was either gasketed to the starter housing (if located on
           the starter motor) or sealed with epoxy (if located away from the starter
           motor).

     d.    The terminals were covered with protective boots or other material to avoid
           accidental shorting.

     Generator, Voltage Regulator, Switches, Lighting, and Auiiliary Systems

     The following modifications were made:

     a.    The generator system was equipped with an enclosed marine—type alternator
           and voltage regulator.

     b.    Protective boots or covers were placed on exposed electrical terminals and
           battery terminals to protect against accidental shorting.

3.   Ignition System

     The ignition systems were modified in one or more of the following ways:

     a.    If necessary, "Standard Equipment" high tension wire was replaced with high
           temperature silicon rubber ignition wire. This measure eliminates arcing to
           ground through insulation leaks on lower quality wire. Most of the late model
           vehicles came equipped with the rubber wire.

           The contact points were replaced with a solid—state ignition system.

     c.    The distributor was modified to reduce the chance of flame escaping from the
           distributor if hydrocarbon vapor is ignited inside the distributor. The following
           modifications were generally done:


     i.     A new distributor cap was installed to reduce the chance of arcing through an
            electrical leak in an old cap.

     ii.    A clamp was installed to securely hold the distributor cap in place in case of
            an ignition of vapor inside the distributor. The clamp consisted of a metal bar,
            drilled to allow the connector wells to penetrate and be clamped to the
            distributor body.

     fii.   The vacuum advance unit was removed. A metal cover was installed and
            sealed with epoxy,. The vacuum advance units in the 1980 model year vehicles
            were not removed since these vehicles have electronic ignition systems.

     iv.    A flame arrestor vent was installed in the distributor body.

The Refinery has obtained some late—model Ford vehicles for use in restricted areas of
the Refinery. However, these vehicles‘ distributors have a two—piece cap and cannot be
sealed. Therefore, the Refinery intends to replace the existing ignition systems with
Mallory Unilite systems. However, modifications fi—iv (above) will still be required.
