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 or 2.5 g/bhp-hr. This exemption excludes all engines equipped with an exhaust gas recirculation system and/or an aftertreatment emission control system such as a catalytic converter or a diesel particulate filter.This exemption is only valid provided the engines meet the following operating conditions: (1) the engine exhaust temperature is greater than or equal to 260 degrees Celsius for 40-50 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—13

                                 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 (ARB) by Section 27156 of the
Vehicle Code; and

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

IT IS ORDERED AND RESOLVED: That installation of the Continuously Regenerating
Technology (CRT) Particulate Filter, manufactured by Johnson Matthey of 380 Lapp Road,
Maivern, 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) or lower.

This Executive Order includes engines originally certified to meet a non—methane
hydrocarbons plus oxides of nitrogen emission standard of 2.4 or 2.5 g/bhp—hr.

This Executive Order excludes all engines equipped with an exhaust gas recirculation
system and/or an aftertreatment emission control system such as a catalytic converter or a
diesel particulate filter.

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

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 260 degrees
Celsiug for 40 to 50 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 parts per
million by weight.

This Executive Order is based on emission 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 emissions impact is expected
when the CRT Particulate Filter is installed on heavy—duty vehicles equipped with any of the
engines listed above.

This Executive Orderis valid provided that installation instructions for the CRT Particulate
Filter do not recommend tuning the vehicle to specifications different from those of the         :
vehicle manufacturer.                                                                            |


                                              «2.

Changes made to the design or operating conditions of the CRT Particulate Filtér\, as
exempt by the ARB, which adversely affect the performance of the vehicle‘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 ARB.

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 ARB 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.

exhaust inlet/outlet 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.
