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 devices exempted under this Executuve
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
emissions. The same emissions impact is expected when the AZ Purifier and AZ
Purimuffier are installed on any of the engines listed above.

'Thl.S Executive Order is valid provided that installation instructions for the AZ Purifier and AZ
 Purimuffler do not recommend tuning the engines to specifications dlfferent from those of
 the engine manufacturer.
