State of California AlIR RESOURCES BOARD EXECUTIVE ORDER D—702U Relating to Exemptions under Sections 38390 and 38391 of the Vehicle Code ESW Technologies | ThermaCat Diesel Particulate Filter Pursua'nt to the authority vested in the Air Resources Board by Part 5, Division 26 of the Health and Safety Code and Sections 38390, 38391, and 38395 of the Vehicle Code; and . Pursuant to the authority vésted in 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 ThermaCat diesel particulate filter, manufactured by ESW Technologies of 200 Progress Drive, ~ Montgomeryville, Pennsylvania 18936, has been found not to reduce the effectiveness of the applicable engine pollution control system, and therefore, the ThermaCat diesel particulate filter is exempt from the prohibitions in Sections 38390 and 38391 of the Vehicle Code for installation on 1996 through 2010 model—year Tier 1 and Tier 2 off—road compression—ignition engines with displacements from 3 to 17 liters. The exemption covers engines used in mobile applications. It does not cover engines used in stationary applications such as pumps, compressors, or generators. This Executive Order excludesall engines originally equipped with an aftertreatment . emission control system such as a catalytic converter or a diesel particulate filter. The ThermaCat diesel particulate filter consists of a diesel oxidation catalyst, diesel particulate filter, fuel injection system, pressure sensor, temperature sensors, and an electronic control unit. Major components of the ThermaCat diesel particulate filter are identified in Attachment A. _ This Executive Order is based on emission testihg and engineelring evaluation of the | impact the ThermaCat diesel particulate filter may have on engine emissions. This Executive Order is valid provided that installation instructions for the ThermaCét diesel particulate filter do not recommend tuning the engines to specifications dn‘ferent from those of the engine manufacturer. Changes made to the design or operating conditions of the ThermaCat diesel 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 theThermaCat diesel particulate filter using identification other than that shown inthis Executive Order or for an application other than that listed in this

7. Executive Order shall be prohibited unless prior approval is obtained from the Air Resources Board. | This Executive Order shall not apply to any ThermaCat diesel particulate filter advertised, offered for sale, sold with, or installed on an engine, vehicle, or equipment 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 ThermaCat diesel particulate filter may have on any warranty either expressed or implied by the engine manufacturer. ' No claim of any kind, such as "Approved by the Air Resources Board," may be made with respect to the action taken hereinin any advertising or other oral or written communication. ‘ ‘ > 4& 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 2474, 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 ESW TECHNOLOGIES‘ THERMACAT DIESEL 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 determipation is made after a hearing that grounds for revocation exist.

EVALUATION SUMMARY Manufacturer Name: ESW Technologies Name of Device: ThermaCat diesel particulate filter Background: ESW Technologies (ESW) of 200 Progress Drive, Montgomerywlle Pennsylvama 18936 has requested exemption of its ThermaCat diesel particulate filter from the prohibitions in Section 38391 of the California Vehicle Code. The ThermaCat diesel particulate filter is designed for use on 1996 through 2010 model—year Tier 1 and Tier 2 off—road compression— ignition engines with displacements from 3 to 17 liters. Recommendation: Grant exemption to ESW as requested and issue Executive Order D—702U. The exemption covers ThermaCat diesel particulate filter installed on 1996 through 2010 model—year Tier 1 and Tier 2 off—road compression—ignition engines with displacements from 3 to 17 liters. . The exemption covers engines used in mobile applications. It does not cover engines used in stationary applications such as pumps, compressors, or generators. This exemption is not valid for any engines originally equipped with an aftertreatment emission control system such as a catalytlc converter or a diesel particulate filter. Major components of the ThermaCat diesel partlculate filter are identified in Attachment A. — Device Description: ' The ThermaCat diesel particulate filter is an actively regenerated filtration system _ designed to reduce hydrocarbons, carbon monoxide, and particulate matter emissions from diesel engines. It consists of a diesel oxidation catalyst (DOC), diesel particulate filter (DPF), fuel injfection system, backpressure sensor, temperature sensors, and an electronic control unit (ECU). Particulate matter in the engine exhaust is captured on the ceramic wall—flow filter. The filter is catalyzed to maximize passive regeneration. DOC, installed upstream of the DPF, also promotes regeneration by increasing the exhaust temperature. When a pre— determined condition is met (backpressure and exhaust temperature), fuel is injected in the exhaust pipe between the exhaust manifold and the DOC. Fuel injection further increases exhaust temperatures by promoting oxidation of hydrocarbons and raising the exhaust temperature to the level required to support regeneration. The amount of injected fuel is controlled by the ECU. The DOC—DPF module is installed with exhaust pressure and temperature sensors. The system requires annual maintenance which includes cleanmg of the injector nozzle, _DPF ash removal, and overall system check. Discussion/Basis for the Recommendation: | In support of its exemption request, ESW provided the following emission data: C1 8—Mode Test Results* * (g/ohp—hr) THC CO NOx PM Baseline tests 0.155 1.104 5.256 0.1086 Thermacat without w* fuel injection Degreened tests 0.007 0.057 4.842 0.0059 Thermacat with fuel injection Degreened testsw 0.007 0.057 4.843 0.006§ Tier 1 emission standards 1.0 8.5 6.9 0.4 Caterpillar certification levels 0.1 0.2 5.5 0.2

(Page 2 of 2) Notes: * Reported data are averages of three hot start tests. ** The device was degreened for 25 hours. Test engine: 1996 Caterpillar 14.6 liter 3406 289 hp engme engine family TCP14. RZDBRJ Test system: DOC ESW & DPF ESW Test: 180 8178 C1 8—mode steady—state engine dynamometer test Emission tests were conducted at ESW America, Inc. (ESWA; also known as Air Testing Services (ATS)) in Montgomeryville, Pennsylvania. Data on the off—road engine showed no adverse emission impact from using the Thermacat diesel particulate filter. To further support its exemption request, ESW provided field use information. The Thermacat diesel particulate filter was installed on a Caterpillar dozer (engine family 1CPXL10.5MRG; Tier 1) and operated for 1,020 hours. No problems or issues were encountered during its operation.. Similar results are expected when the system is used on any of engines include in this application.
