OPS-1 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 IS ORDERED AND RESOLVED: That installation of the OPS-1, manufactured by Oil Purification Systems, Inc. of 2176 Thomaston Avenue, Waterbury, Connecticut 06704, has been found not to reduce the effectiveness of the applicable vehicle pollution control systems, and therefore, are exempt from the prohibitions in Section 27156 of the Vehicle Code for installation on 2007 model-year and older heavy-duty diesel engines with pressurized oil systems. The OPS-1 device is a two-stage oil refining system consisting of a Filtration chamber and an evaporation chamber. It is set-up as a closed-loop system with the evaporative emissions from the evaporation chamber vented back into the air intake system. This Executive Order is based on engineering evaluation which determined that the device when installed on 2007 and older heavy-duty diesel engines with pressurized oil syste'ms will not adversely affect the performance of emission control systems of affected engines. This Executive Order is valid provided that installation instructions for the OPS-1 do not recommend tuning the vehicles to specifications different from those of the vehicle manufacturer. Changes made to the design or operating conditions of the OPS-1, as exempt by the Air Resources Board, which adversely affect the performance of ,the vehicles' emission control system, shall invalidate this Executive Order. Marketing of the OPS-1 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. Exemption of the OPS-1 shall not be construed as exemption to sell, offer for sale, or advertise any component of the systems as an individual device.

This Executive Order shall not apply to any OPS-1 advertised, offered for sale, sold with, or installed on a niotor 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 OPS-I 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 OIL PURIFICATION SYSTEMS, INC.'S OPS-1. 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 the hearing that grounds for revocation exist. Executed at El Monte, California, this 26 day of June 2007. Annette Hebert, Chief Mobile Source Operations Division OIL PURIFICATION SYSTEMS, INC. - OPS-1 - D-621
