         Phase 2 Reformulated Gasoline Performance Subcommittee

                  Meeting Summary    November 15, 1994

I.   Introduction

     The performance committee discussed the following key issues
     regarding the Phase 2 Reformulated Gasoline performance and
     compatibility demonstration efforts:

       -  Results of Phase 2 Gasoline Test by Federal Express
       -  On-Road Test Protocol
       -  Bench Test Program
       -  Criteria for Identifying Potential Vehicle Problems
       -  Test Fuel Explosivity

     The minutes from the October 4, 1994 meeting were approved
     with no changes.  Copies of presentations given at the
     meeting are enclosed with this summary.

II.  Results of Phase 2 Gasoline Test by Federal Express

     The Federal Express Clean Fleet Project tested several fuels
     over a 2 year period in Southern California.  Phase 2
     Reformulated Gasoline (RFG) was tested.  There were no fuel
     related problems from Reformulated Phase 2 Gasoline (RFG).

III. On-Road Test Protocol

     Discussion was held regarding the current availability of
     vehicles for the test program.  ARB staff requested
     suggestions of alternative fleets to increase the number of
     pre-1985 vehicles and imports.  Many of the currently
     identified potential fleets have only newer domestic
     vehicles and have not committed to participating in the test
     program yet.

     ARB staff will provide a list of the currently selected
     vehicles to subcommittee members for their review.
     Additionally, staff has been attempting to collect repair
     information for the vehicle population, and staff findings
     will be reported at the next meeting.

     The vehicle evaluation survey forms have been modified to
     reflect the changes suggested by members from the previous
     meetings with some additional changes.  Visual inspections
     of vehicles will still be done on a monthly basis, but the
     driveability incidence log will only be used to report
     problems, rather than to report on a weekly basis.  The
     December Revised Test Protocol, enclosed, contains a copy of
     the latest forms.  These forms also incorporate changes
     suggested at this meeting.

     Some questions were raised as to how feasible the
     specifications for the test fuel were for the fuel blender.
     To ease the process in contracting for test fuel,
     subcommittee members agreed to allow changing the upper
     limit on the T90 specification from 300 to 310 degrees if
     310 degrees becomes necessary for practical blending.

IV.  Bench Test Program

     GM will bench test the following five fuels for various
     elastomer property changes:

          Baseline - RFA
          Phase 2 Basic/Vehicle Test Fuel
          Phase 2 Ethanol - Blended Test Fuel
          Phase 2 Low - Aromatic Test Fuel
          ASTM Fuel C - to be used for internal checking of the results

     Data from the GM bench tests are expected to be available in
     May or June 1995.  GM will compare the swell characteristics
     of the elastomers and determine whether a problem could be
     expected, but they will also provide the results to other
     automobile manufacturers for their independent analysis.

     Ford Motor Company proposed to bench test six fuels to study
     the effects of various lubricity levels.  The test will
     provide a relative ranking of the fuels for their wear
     characteristics and should address mechanical wear issues in
     fuel pumps and injectors.

V.   Test Fuel Explosivity

     Chevron is testing the flammability of low RVP fuels for
     oxygenated and non-oxygenated fuel blends.  Testing started
     in October 1994 and is expected to be complete near the end
     of April 1995.
