                                 State of California
                             AIR RESOURCES BOARD

                            EXECU-TIVE ORDER D-584-1

                         Relating to Exemptions under Section 27156
                                 of the Vehicle Code

                                Tested Products (d.b.a. DEC)
                              "Used OEM Catalytic Converters"

WHEREAS, Vehicle Code Sections 27156 and 38391, and Section 2222(i) of California Code
of Regulations (CCR) Title 13, authorize the California Air Resources Board and its Executive
Officer to exempt used tested original equipment manufacturer (OEM) catalytic converters from
the prohibitions of Vehicle Code Section 27156.

WHEREAS, Tested Products of 14645 Keswick Street, Van Nuys, California 91405, has applied
to the Air Resources Board for exemption from the prohibitions in Vehicle Code Sections 27156
and 38391 to market its used bench screened OEM catalytic converters for installation on
vehicles similar to the ones from which they were salvaged in California. Tested Products shall
salvage OEM catalytic converters, including those monitored by the on-board diagnostic II
(OBD II) system, perform the bench screening test to determine if they meet the required
conversion efficiency, replace the end pipes, if necessary, and catalog them for sale and
installation on vehicles with the same engine family as the ones from which the catalytic
converters were recovered.

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 3951 6 and Executive Order G-02-003, Air Resources Board finds that Tested
Products laboratory screens used OEM catalytic converters using test procedures acceptable to
the Air Resources Board and, therefore, complies with California Vehicle Code Section 27156
and Section 2222(i) of Title 13, CCR.

WHEREAS, conversion efficiency correlation tests conducted at Automotive Testing and
Development Services, Inc. (ATDS), Ontario, California, using a 1999 2.2L Chevrolet S-10
certified with OBD II TWC, and a 1989 5.OL Chevrolet Camaro certified with TVVC + OC showed
that the conversion efficiencies obtained from Tested Products' bench screening were within1 5
percent of those obtained from cold-start CVS-75 FTP test as specified by Air Resources

IT IS HEREBY RESOLVED that used catalytic converters bench screened by Tested Products
are exempt from the prohibitions in Vehicle Code Section 27156 for installation on appropriate
vehicles subject to the following conditions:

I.    Used OEM catalytic converters marketed in California must attain the minimum
      conversion efficiencies shown below within the specified time after the engine exhaust is
      switched from the straight pipe to pass through the catalytic converter:


Converter Type              HC             CO              NOx            Test Duration (sec)
OC                          70             70              N/A            60
                                                                          ~   -

TWC                         70             70              60             60
TWC + OC                    70             70              50             60
                                                                          ~   -

Precatalyst (OBD II)        70             70              60 forTWC      60
Precatalyst (non-OBD 11)    40             40              N/A for OC     60

2.    This exemption does not authorize Tested Products to open used OEM catalytic
      converters, modify their internal components, or switch substrates from one shell to
      another. The exemption allows the replacement of the end pipes only, if necessary.

3.    No changes are perrr~ittedto the used OEM catalytic converters as described in the
      application for exemption. Any changes to the used OEM catalytic converters or any of
      their components, and other factors addressed in this order must be evaluated and
      approved by Air Resources Board prior to marketing in California.

4.    Marketing of the used OEM catalytic converters using identifications other than those
      shown in the exemption application, and in this Executive Order, or marketing of the
      used OEM catalytic converters for installation on vehicles other than those from which
      they were recovered shall be prohibited unless prior approval is obtained from Air
      Resources Board. Exemption of this product shall not be construed as an exemption to
      sell, offer for sale, or advertise any components of the used OEM catalytic converters as
      individual devices.

5.    Any oral or written references to this Executive Order or its content by Tested Products,
      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 used OEM catalytic
      converters and is only a finding that the used OEM catalytic converters are exempt from
      the prohibitions of Vehicle Code Section 27156.

6.    Tested Products' installation instructions for the used OEM catalytic converters must
      conform to requirements in Paragraphs I and IX of California Evaluation Procedures for
      New Aftermarket Non-Original Equipment Catalytic Converters.

7.    Tested Products must abide by the warranty of 25,000 miles for non-OBD ll catalytic
      converters and 50,000 miles for OBD II catalytic converters, which it specifies in ,the
      warranty card submitted to Air Resources Board with its application.

8.    Tested Products may not advertise or refer to the bench screened used OEM catalytic
      converters as "remanufactured" catalytic converters.


9.    Tested Products must submit to the Air Resources Board for review its quality audit data
      or quality control procedures, as well as its production quantity data for each catalytic
      converter type tested. The information should include the nurr~berof used OEM catalytic
      converters returned for warranty replacement or refund. This information must be
      submitted on a semi-annual basis no later than July 30 and January 30 for each
      production year.

10.   Tested Products will be required to adopt new bench test procedures or demonstrate the
      adequacy of the existing procedures should Air Resources Board determine that new
      bench test procedures may be more appropriate for testing used OEM catalytic
      converters based on the following: (a) If a new regulation requires a change in the test
      procedures or in required minimum conversion efficiency of any of the pollutants, (b) If
      new information shows that the current procedures have become inadequate due to new
      vehicle or test equipment technology.

Violation of any of the above conditions shall be grounds for revocation of this order. The order
may be revoked only after ten day written notice of intention to revoke it, during 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 is made, after the hearing, that grounds for revocation

Exec~~tiveOrder No. D-584 dated February 2, 2005, is hereby supersededand of no further
force and effect.

Executed at El Monte, California, this /<%ay      of August 2005.
