         "NEW AFTERMARKET THREE—WAY PLUS OXIDATION CATALYTIC CONVERTER®

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, Maremont Exhaust Products,    Inc.    of 2400 Industrial Park,     Loudon,
Tennessee 37774, has applied to the ARB for exemption from the prohibitions
in Vehicle Code Sections 27156 and 38391 for their new aftermarket three—way
catalytic converter (TWC + OC)) for the following application:

Converter     Use        Part Number                Max.    Enq.        Max. Test
Type           '                                    Size                Weight

The catalysts can be used to replace non—~functioning original equipment
manufacturer (OBM) catalysts on vehicles that are no longer under vehicle
manufacturer‘s emission control systems warranty.

WHEREAS, pursuant to the authority vested in the Executive Officer by Health
and Safety Code Section 39515 and in the Chief, Mobile Source Division by
Health and Safety Code Section 39516 and Executive Order G—45—9,           the ARB
finds that the above aftermarket catalytic converters comply with the

converter was based on durability mileage accumulation of 25,000 miles using
the AMA durability driving schedule (Reference Appendix IV, Title 40, part
86, Code of Federal Regulations (June 28,      1977)).

IT IS HEREBY RESOLVED that the above catalytic convertér 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 converter as described in the
         application for exemption.  Any changes to the 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.

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

        include the disclaimer that the Ekecutive Order or the exemption it
        provides is not an endorsement or approval of any emissions reduction
        claims   for the catalytic converter and is only a   finding that the
        converter are exempt from the prohibitions of Vehicle Code Section
        27156.

   4.   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.

   5.   Maremont must submit production audit test data for the catalyst to

                                      SUMMARY




         Maremont Exhaust Products, Inc.      (Maremont} of 2400 Industrial Park

Boulevard,   Loudon,   Tennessee 37774,   has applied for an exemption of their

new aftermarket three—way plus oxidation catalytic converter (TWC + OC) from

the prohibitions in Vehicle Code Sections 27156 and 38391 in accordance with

California requlations on new aftermarket catalytic converters.          The

catalyst was constructed using the front substrate from Maremont‘s

California exempted TWC number 28802       (5.7L/6,000 lbs.),   and the rear

substrate from their oxidation converter (OC) number‘28706         (7.51/6, 000

lbs.).   The recanned —converter was tested using a 5.9L/5,500 lbs.       vehicle

for TWC + OC application.

         Emissions data submitted by the applicant show that the catalytic

converter meets the requirements of Vehicle Code Section 27156 and Title 13,

California Code of Regulations,     Section 2222(h)   for the stated application.

Based on the above, the staff recommends that the exemption be granted as

requested and that Executive Order D—184—9 be issued.

    I.         INTRODUCTION

              Maremont Exhaust Products, Inc.    (Maremont) of 2400 Industrial Park

    Boulevard, Loudon, Tennessee 37774, has applied for an exemption from the

    prohibitions in Vehicle Code Sections 27156 and 38391 for their new

    aftermarket three—way plus oxidation catalytic converter      (TWC + OC)     in

    accordance with California regulations on new aftermarket catalytic

    converters.    The new aftermarket TWC + OC is intended for use on light—

    duty/medium—duty vehicles as shown below:

    Maremont recanned catalysts previously exempted by the ARB in order to

    obtain a TWC + OC application for light—duty/medium—duty vehicles.           The

    substrates were obtained from the following California exempted catalysts:

    II.       CONCLUSION


              The applicant has submitted all the required information,      and based

    on the submitted exhaust emissions test data,     the staff concludes that the

    catalytic converter meets the criteria set forth in Vehicle Code Section

    27156 and Title 13, California Code of Regulations, Section 2222(h)          for the

    stated applications.


III.    RECOMMENDATION

        Staff recommends that the exemption be granted as requested and that

Executive Order No. D—184—9 be issued, permitting the advertisement,            sale,

and installation of the new aftermarket catalytic converter on applicable

vehicles.

Iv.     DEVICE DESCRIPTION

        Maremfint's new aftermarket TWC + OC contains two substrates.                The

front reducing substrate is coated with palladium and rhodium in the ratio

of 5:1, the rear oxidizing substrate is coated with palladium only.             Air

tube is incorporated in the middle of the front and rear substrates.                The

front and rear substrates each measures 5.7 inches along the major axis, 3.2

inches along the manor axis,   2.96 inches long,       and has a volume of 45.8

cubic inches.    Front and rear metal loading is in the ratio of l:1.1.              The

substrates are enclosed inva stainless steel shell.             The substrates are

wrapped with compressed intumescent mat to prevent vibration and exhaust

gases from by—passing the catalyst.       A heat shield of aluminized steel is

welded to the converter shell to protect the vehicle underbody from heat.

The catalytic converter may be sold as a unit with installation instructions

and kits as shown in Maremont‘s application catalog.             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.                      ‘

v.      DEVICE EVALflATION

        Maremont submitted data from testing conducted by Automotive Testing

Development Services, Inc., Ontario,      California.        The test vehicle has

equivalent test weight (ETW) of 5,500 lbs.          Emissions test§ were conducted

on the following vehicle:


Application     Emission Test Vehicle          Engine Size      ETW
TWC + OC        1990 Dodge D—150 Truck         5.91             5,500 lbs.

                                         —2—


     The Air Resources Board (ARB) did not conduct confirmatory tests on the new
mm




     aftermarket TWC + OC since the catalysts have been returned to their

     original configuratibn.    In lieu of confirmatory testing, the ARB is

     requiring Maremont to conduct product audit tests during the next production

     audit réporting period.    The test results and conversion efficiencies for

     the converter are shown below:



                                ATDS,   Ontario,   California

     co (g/mi)    35.155       7.435           8.905        76.7%
     NoOx(g/mi)    2,480       1.160           1.214        52.1%

     The above conversion efficiencies meet the minimum requirements of the

     California regulations on new aftermarket catalytic converters.
