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.

State of California AIR RESOURCES BOARD 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.
