                             EXECUTIVE ORDER D—182—29

                           Relating to Exemptions under Section 27156
                                    of the Vehicle Code

                            Walker Manufactufing Company

WHEREAS, Vehicle Code Sections 27156 and 38391, and Title 13, California Code of
Regulations (hereafter "CCR") Section 2222(h), authorize the California Air Resources Board
(ARB) and its Executive Officer to exempt new aftermarket catalytic converters from the
prohibitions of Vehicle Code Section 27156.

WHEREAS, Walker Manufacturing Company (Walker), a Tenneco Automotive Division, of 2701
N. Dettman Road, Jackson, Michigan 49201, has applied to the ARB for exemption from the
prohibitions in Vehicle Code Sections 27156 and 38391 to market their series 99200 new
aftermarket three—way plus oxidation catalytic converter (TWC + OC) for the following
applications, except for vehicles equipped with an On—Board Diagnostic II (OBD—II) system (Titie
13, CCR, Section 1968.1):

Converter Type      Series Number   Converter Use    Max. Eng. Size        Max. Veh. Test Wt.

WHEREAS, pursuant to the authority vested in the Executive Officer by Health and Safety Code
Section 39515 and in the Chief, Mobile Source Operations Division by Health and Safety Code
Section 39516 and Executive Order G—02—003, the ARB finds that the above aftermarket
catalytic converter complies with the California Vehicle Code Section 27156 and Title 13,
California Code of Regulations, Section 2222(h). Emission performance of the catalytic
converter was based on durability bench aging conducted by Johnson Matthey Catalyst
Systems Division using the ARB—modified RAT—A bench—aging procedures in lieu of the 25,000—
mile AMA driving cycle (Reference Appendix IV, Title 40, part 86, Code of Federal Regulations
(June 28, 1977)).

WHEREAS, emissions tests conducted at Automotive Testing and Development Services
(ATDS) laboratory, Ontario, California, using a 1989 5.9L Dodge Ram Van, and a 1995 5.9L
Dodge Pickup 2500 showed the following conversion efficiencies which meet the minimum
requirements for new aftermarket catalytic converters:

IT IS HEREBY RESOLVED that the above catalytic converter is exempt from the prohibitions in
Vehicle Code Section 27156 for installation on the approved application vehicles subject to the
following conditions:

      1.     No changes are permitted to the catalytic converter as described in the application
             for exemption. Any changes to the catalytic converter or any of its components,
             and other factors addressed in this order must be evaluated and approved by the
             ARB prior to marketing in California.

             Marketing of the catalytic converter using identifications other than those shown in
             the exemption application, and in this Executive Order, or marketing of the
             catalytic converter for application other than the ones shown in this Executive
             Order shall be prohibited unless prior approval is obtained from the ARB.
             Exemption of this product shall not be construed as an exemption to sell, offer for
             sale, or advertise any components of the catalytic converter as individual devices.

            Any oral or written references to this Executive Order or its content by Walker
            Manufacturing Company, its principals, agents, employees, distributors, dealers,
            or other representatives must include the disclaimer that the Executive Order or
            the exemption it provides is not an endorsement or approval of any emission
            reduction claims for the catalytic converter and is only a finding that the catalytic
            converter is exempt from the prohibitions of Vehicle Code Section 27156.

            Walker Manufacturing Company‘s installation instructions for the new catalytic
            converter must conform to requirements in Paragraphs | and IX of California
            Evaluation Procedures for New Aftermarket Non—Original Equipment Catalytic
            Converters.

            Upon installation, the catalytic converter must carry a manufacturer‘s warranty for
            25,000 miles on the substrates and 50,000 miles or five years on the shell and
            end pipes.

WALKER: MANUFACTURING COMPANY — CATALYTIC CONVERTER — D—182—29


                                     EVALUATION SUMMARY

 Manufacturer Name: Walker Manufacturing Company

 Name of Device; Series 99200 Three—way plus oxidation catalytic converter (TWC + OC).

Background:
            Walker Manufacturing Company (Walker), a Tenneco Automotive Division, of 2701
N. Dettman Road, Jackson, Michigan 49201, has applied for an exemption from the prohibitions
in Section 27156 of the California Vehicle Code (VC) for its series 99200 new aftermarket TWC
+ OC. The new aftermarket catalytic converter is for installation on vehicles with up to
maximum limits of 5.9L engine size and 6,000 pounds equivalent test weight (ETW) except for
vehicles equipped with On—Board Diagnostic I! (OBD II) system.

Recommendation:
          Grant exemption to Walker as requested, and issue Executive Order
D—182—29.

Device Description:
              Walker‘s new aftermarket TWC + OC is designed to use two oval ceramic monolith
substrates. The front and rear substrates are both coated with platinum and rhodium in the
ratio of 2:1. The dimensions of the front and rear substrates are 4.15 inches for the major axis,
3.15 inches for the minor axis, and 2.0 inches in length. The combined volume of the front and
rear substrates is 51.0 cubic inches. The substrates are contained in a shell constructed from
409—draw quality stainless steel. The substrates are wrapped with an intumescent mat paper,
to prevent vibration and exhaust by—pass. The shell is sealed by seam weld, and a piece of
aluminized heat shield is spot—welided to the upper side of the catalytic converter to protect the
vehicle underbody from excessive heat. The catalytic converter may be sold as a unit with
installation instructions or may be used in customized direct fit exhaust applications. It is 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.
            Johnson Matthey Catalytic Systems Division, based in Wayne, Pennsylvania, is the
catalyst supplier for Walker‘s series 99200 TWC + OC.

Discussion/Basis for Exemption Recommendation:
             Walker submitted data on the series 99200 TWC + OC from testing conducted at
Automotive Testing and Development Services (ATDS) laboratory, Ontario, California. The
catalyst bench aging was conducted by Johnson Matthey, using the ARB—modified RAT—A
bench aging procedures. Emission tests were conducted on a 1989 Dodge Ram Van 5.9L for
the TWC + OC application, and on a 1995 Dodge Pickup 2500 5.9L for the TWC application.
             The evaluation of the new aftermarket catalytic converter is solely based on the
bench aging conducted by Johnson Matthey and the emission tests conducted at the ATDS.
The limits of application for Walker‘s series 99200 TWC + OC will be 5.9L/6,000 lbs., with the
corresponding maximum gross vehicle weight rating (GVWR) of 7,500 Ibs. Testing consisted of
two cold—start CVS—75 tests with a simulator ("dummy" catalyst), followed by two cold—start CVS—
75 tests for each of the test catalysts. The average of the two test results for each test catalyst
was used to calculate the conversion efficiency. The test catalysts were labeled 1A and 2A.
The overall conversion efficiency for the catalyst model is the average conversion efficiency of
the two test catalysts. The test results for the series 99200 catalyst are shown below:

The above test results meet the minimum requirements of the California regulations on new
aftermarket catalytic converters. The Air Resources Board (ARB) did not conduct confirmatory
tests on the new aftermarket catalytic converter.
