 A—55 INJECTOR UPGRADE AND TIMING MODIFICATION                                      (Page 2 of 2)




 This Executive Order is granted based on comparison of emissions in the
 modified configurations with the applicable emissions standards.  The engine
 tested was a 1985 federally certified Detroit Diesel GV92TA.  The emissions
 results are shown below (in grams per brake—horsepower—hour):

                                     HC        co                NOx               PM
     A—55        (weighted)   _     0.79      0 .49           7 .64            0 .087
     Federal Standards              1.3      15.5        10 .7                 O .6

 The emissions in the modified configuration were within the applicable
 standardas. The emissions testing was conducted on a federally certified
 engine, but A—55 submitted development data which predicts the behavior of the
 applicable California engines.  Development data indicate that emission test
 results in a federally certified engine are representative of California—
 certified engines.  Therefore, based on the test results, the A—55 Injector
 Upgrade and Timing Modification meets the criteria for exemption of general
 criteria parts.

 No claim of any kind, such as "Approved by the Air Resources Boafd", may be
 made with respect to the action taken herein in any advertising or other oral
 or written communication.

 violation of any of the above conditions shall be grounds for revocation of
 this order.  The order may be revoked only after a ten—day written notice of
 intention to revoke the order, in which period the holder of the order may
 request in writing a hearing to contest the proposed revocation.  If a hearing
 is requested,     it shall be held within ten days of receipt of the request and
 the order may not be revoked until a determination after hearing that grounds
 for revocation exist.
