                          CALIFORNIA CODE OF REGULATIONS SECTION 2222(h)


     I.         INTRODUCTION

                Walker Manufacturing Company (Walker) of 2701 N. Dettman Road, Jackson,

     Michigan 49201, has applied for an exemption from the prohibitions in Vehicle Code

     Sections 27156 for their new series 97000 aftermarket three—way plus oxidation

     catalytic converter (TWC + OC) in accordance with California reqgulations on new

     aftermarket catalytic converters.        The ceramic monolith substrates of the new catalyst

     were manufactured by AlliedSignal Environmental Catalyst       (ASEC).   <The new aftermarket

     catalyst is intended for the following vehicle application:


     Cconverter Type    Converter Use    PN/Series      Max. Eng.   Max. Veh.
                                                        Size        Test Wt.
     TWC + OC           TWC + OC          97000         5 . 9L      6,000 lbs.
     TWC + oC           TWC               97000   _      5. 9L      6,000 ibs.
     TWC + OC           0C                97000          5. 9L      6,000 lbs.


     Walker intends to ma;ket the new TWC + OC as a replacement for catalytic converters on

     applicable vehicles whose manufacturers‘ warranty has expired and the need for

     replacement of the original equipment manufacturer (OEM) catalytic converter has been
ul




     established and documented.        Excluded from the application are those vehicles equipped

     with an On—Board Diagnostic System II {OBD—II).

     II.           CONCLUSION

                   The applicant has submitted all the required information,     and based on the

     applicant‘s submitted exhaust emissions test data, the staff concludes that the new

     aftermarket catalyst meets the criteria set forth in Vehicle Code Section 27156,         and

     Title 13, California Code of Reqgulations, Section 2222(h) for the stated application.

     III.          RECOMMENDATION

                   Staff recommends that the exemption be granted as requested and that

     Executive Order No. D—182—25 be issued, permitting the advertisement, sale, and

     installation of the new aftermarket catalyst on applicable vehicles.

     IV.           DEVICE DESCRIPTION

                   Walker‘s new aftermarket TWC + OC is designed to use oval ceramic monolith

     substrates.     The front substrate is coated with rhodium,    and the rear substrate is

     coated with palladium.        Each substrate measures 4.75 inches along the major axis, 3.15

     inches along the minor axis, and 1.92 inches in length, and has a volume of 24.35


cubic inches.       The substrates are contained in outer 409 stainless steel shell with

intumescent mat,      to prevent vibration and éxhaust by—pass.                The shell is sealed by

seam weld,      and bushings are attached by arc welding.             Aluminized soft steel heat

shield is spot—welded to the upper and bottom sides of the converter to protect

vehicle underbody from excessive heat,              and prevent materials on the ground from direct

contact with the catalyst shell.             The catalyst may be sold as a unit with installation

instructions or may be used in customized direct fit exhaust application.                     It is also

sold with a warranty for 25,000 miles on the substrates, and five years or 50,000

miles on the container or shell;            and the end pipes.

v.              DEVICE EVALUATION

                Walker submitted data from testing conducted by Automotive Testing and

Development Services         (ATDS),   Ontario,    California.     Thé test catalysts were aged by

AlliedSignal Environmental Catalyst using their ARL—102                    (RAT B) bench—aging cycle for

53 hours.       The test catalysts were shipped directly to ATDS where the emissions tests

were conducted for three—way plus oxidation (TWC + OC) application using a 1989 Dodge

350 Van 5.9L.       Three—way (TWC) application tests were conducted on a 1995 Dodge Ram

2500 Truck 5.9L, and oxidation catalyst application tests were conducted on a 1979

Ford Pickup Truck 7.6L.          All tests were conducted at the equivalent test weight            (ETW)

of 6,000 lbs.       The test vehicles were ballasted in order to achieve the required ETW

of 6,000 pounds.       The test catalysts were labeled 6926 and 6927.                Testing consisted of

two cold—start CVS—75 with a simulator              ("dummy"    catalyst),    followed by two cold—start

CVS—75 for each of the test catalysts.               The test results for the catalyst are shown
