The injection system includes a combined dosing pump and electronic control unit, valve manifold, urea/air atomizer, and a urea storage tank. The sensors include a NOx sensor, mass air flow sensor, and two temperature sensors. The system components exempted under this Executive Order are identified in Attachment A. This exemption is based on emission tests conducted by Haldor Topsa@e A/S with the Urea SCR System. Test data showed that the Urea SCR System has no adverse impact on engine emissions. This Executive Order is valid provided that installation instructions for the Urea SCR System do not recommend tuning the engines to specifications different from those of the engine manufacturer. Changes made to the design or operating conditions of the Urea SCR System, as exempted bythe ARB, which adversely affect the performance of the engine‘s pollution control system, shall invalidate this Executive Order. Marketing of the Urea SCR System 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 Urea SCR System advertised, offered for sale, sold with, or installed on an off—road engine 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 Urea SCR System 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 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 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 HALDOR TOPSOE AS® UREA SELECTIVE CATALYTIC REDUCTION SYSTEM. Viotation of any of the above conditions shall be grounds for revocation of this Executive Ordér. 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.
