Approved Parts

ModelsModification
1991-2004 model-year 4-stroke heavy-duty diesel engines originally certified to meet a particulate matter emission standard of 0.10 g/bhp-hr or lower. This exemption includes engines originally certified to meet a non-methane hydrocarbons plus oxides of nitrogen emission standard of 2.4 g/bhp-hr or higher. This exemption excludes all engines equipped with an aftertreatment emission control system such as a catalytic converter or a diesel particulate filter. This exemption also excludes engines equipped with an exhaust gas recirculation system with the following exceptions: 2003 model-year Cummins 5.9 liter ISB engines and 2003 model-year Cummins 10.8 liter ISM engines.This exemption is only valid provided the engines meet the following operating conditions: (1) the engine exhaust temperature is greater than or equal to 240 degrees Celsius for at least 40 percent of the typical duty cycle, (2) the NOx to PM ratio is at least 8, and (3) the engine is operated using diesel with a maximum sulfur content of 50 ppmw.

                                EXECUTIVE ORDER D—393—14

                                Relating to Exemptions under
                             Section 27156 of the Vehicle Code

                                      Johnson Matthey
                                     CRT Particulate Filter

Pursuant to the authority vested in the Air Resources Board by Section 27156 of the Vehicle
Code; and

Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the
Health and Safety Code and Executive Order G—02—003;

IT 1S ORDERED AND RESOLVED: That installation of the Continuously Regenerating
Technology (CRT) Particulate Filter, manufactured by Johnson Matthey of 380 Lapp Road,
Malvern, Pennsylvania 19355, has been found not to reduce the effectiveness of the
applicable vehicle pollution control system, and therefore, the CRT Particulate Filter is
exempt from the prohibitions in Section 27156 of the Vehicle Code for installation on
heavy—duty on—road vehicles equipped with 1991 through 2004 model—year 4—stroke diesel
engines originally certified to meet a particulate matter emission standard of 0.10 grams per
brake—horsepower—hour (g/bhp—hr) orlower.

This Executive Order includes engines originally certified to meet a non—methane
hydrocarbons plus oxides of nitrogen emission standard of 2.4 g/bhp—hr or higher.

This Executive Order excludes all engines equipped with an aftertreatment emission control
system such as a catalytic converter or a diesel particulate filter. This Executive Order also
excludes engines equipped with an exhaust gas recirculation system with the following
exceptions: (1) 2003 model—year Cummins 5.9 liter ISB engines and (2) 2003 model—year
Cummins 10.8 liter ISM engines.

This Executive Order is only valid provided the engines meet the following operating
conditions: (1) the engine exhaust temperature is greater than or equal to 240 degrees
Celsius for at least 40 percent of the typical duty cycle, (2) the NOx to PM ratio is at least 8,
and (3) the engine is operated using diesel fuel with a maximum sulfur content of 50 parts
per million by weight.

CRT Particulate Filters exempted under this Executive Order are identified in Afttachment A.

This Executive Order is based on emission and field tests conducted by Johnson Matthey
with the CRT Particulate Filter. Testing showed that the CRT Particulate Filter does not
adversely affect the exhaust emissions of the test engines. The same emission impact is
expected when the CRT Particulate Filter is installed on heavy—duty vehicles equipped with          =~
any of the engines listed above.

This Executive Order is valid provided that installation instructions for the CRT Particulate
Filter do not recommend tuning the engine to specifications different from those of the
original engine manufacturer.


                                                 «2.

Changes made to the design or operating conditions of the CRT Particulate Filter, as
exempt by the Air Resources Board, which adversely affect the performance of the engine‘s
pollution control system, shall invalidate this Executive Order.

Marketing of the CRT Particulate Filter using identification other than that shown in this
Executive Order or for an application other than that listed in this Executive Order shall be
prohibited unless prior approval is obtained from the Air Resources Board.

This Executive Order shall not apply to any CRT Particulate Filter advertised, offered for
sale, sold with, or installed on a motor vehicle prior to or concurrent with transfer to an
ultimate purchaser.

This Executive Order does not constitute any opinion as to the effect the use of the
CRT Particulate Filter may have on any warranty either expressed or implied by the vehicle
manufacturer.

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

in addition to the foregoing, the Air Resources Board reserves the right in the future to
review this Executive Order and the exemption provided herein to assure that the exempted
add—on or modified part continues to meet the standards and procedures of California Code
of Regulations, Title 13, Section 2222, et seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION,
ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE
AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING
ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF JOHNSON MATTHEY‘S
CRT PARTICULATE FILTER.

Violation of any of the above conditions shall be grounds for revocation of this Executive
Order. The Executive Order may be revoked only after a ten—day written notice of intention
to revoke the Executive Order, in which period the holder of the Executive 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 Executive Order may not be
revoked until a determination is made after a hearing that grounds for revocation exist.

Executed at El Monte, California, this      __/ 8 7#day of April 2005.

exhaust inletfoutlet configuration, catalyst substrate, and filter element for the engine
horsepower ranges. The catalyst and filter substrate volume/density combinations
specified above are the minimum catalyst and filter sizes Johnson Matthey will use on
a given engine. Johnson Matthey may use a larger catalyst and/or filter for a given
engine/vehicle combination.
