There are federal and state OSHA laws regarding using enriched air for diving (who can under what kind of supervision, etc.), and state laws are usually more restrictive. I'm not sure what the sticking point is for CA laws, but I just completed the sports chalet course for enriched air and the instructor (under contract of Sport Chalet, based in CA), must abide the CA rules, not those of AZ which are more "relaxed." My instructor used Nitrox when he dives, but can't use it with students evidently. Evidently PADI is lobbying to get the CA law changed.
