LINGENFELTER EXECUTIVE ORDER D—333—12 LINGENFELTER 368 CID LT—~S5 ZR—1 EN¢INE (Page 2 of 2) LINGENFELTER 385 CID LT—5 ZR—l1 ENGINE This Executive Order is granted based on the results from previous emission tests conducted in accordance with Cold—Start CVS—75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to believe that use of the Lingenfelter 368 CID LT—5 ZR—1 Engine and the Lingenfelter 385 CID LT—5 ZR—1 Engine may adversely affect émissions of motor vehicles when operating under conditions outside the parameters of the previously prescribed test procedure. Accordingly, the ARB reserves the right to conduct additional emission tests in the future, as such tests are developed, that will more adequately measure emissions from all cycle phases. If such test results demonstrate that the Lingenfelter 368 CID LT—5 ZR—1 Engine or the Lingenfelter 385%CID LT—5 ZR—1 Engine adversely affects emissions during off—cycle conditions (defined as those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal Test Procedure), this Executive Order shall be effectively rescinded as of the date the test results are validated. Further, if such test results or other evidence provide the ARB with reasons to suspect that the Lingenfelter 368 CID LT—5 ZR—1 Engine or the Lingenfelter 385 CID LT~—5 ZR—~1 Engine will affect the durability of the emission control system, Lingenfelter shall be required to submit durability test data to show that the durability of the vehicle emission control system is not, in fact, affected and/or that the add—on or modified part demonstrates adequate durability. In addition to the foregoing, the ARB reserves the right in the future to review this Executive Order and the exemptions 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.
