  IT IS ORDERED AND RESOLVED: That installation of the AZ Purifier and AZ Purimuffler
 devices, manufactured by Engine Control Systems of 165 Pony Drive, Newmarket, Ontario,
  Canada L3Y 7V1, has been found not to reduce the effectiveness of the applicable engine
  emission control system, and therefore, the AZ Purifier and AZ Purimuffler devices are
  exempt from the prohibitions in Sections 38390 and 38391 of the Vehicle Code for
  installation on the off—road compression—ignition engines listed below. This exemption is
. limited to engines subject to California‘s Tier—1 exhaust emission standards
  (i.e. 0.54 g/kW—hr PM and 9.2 g/kW—hr NOx). This exemption is also limited to engines used
 in equipment used at the ports, railway yards, and intermodal operation such as y
                                                                                 a ard

 The AZ Purifier and AZ Purimuffler exempted under this Executive Order can be installed
 on engines operated using standard California diesel with a maximum sulfur content of 500
 parts per million by weight (ppmw), ultra low sulfur diesel (ULSD) with a maximum sulfur
 content of 15 ppmw, or PuriNOx water emulsion fuel based on either standard California
 diesel or ULSD. The AZ Purifier and AZ Purimuffier dev1ces exempted under this Executlve
 Order are identified in Attachment A.

 This exemption is based on emission tests conducted by Engine Control Systems with the
 AZ Purimufflier. Test data showed that the AZ Purimuffler has no adverse impact on engine
 emigsions. The same emissions impact is expected when the AZ Purifier and AZ
 Purimuffler are installed on any of the engines listed above.

exempted bythe ARB, which adversely affect the performance of the engine‘s pollution
control system, shall invalidate this Executive Order.
