Cindy, John,
In some states, (Like NJ) some of these applications fall under the jurisdiction of the state. The state approves the plans and the local AHJ has to inspect the site. In the 2002 NEC sec. 514 there is some new wording about LP dispensing area's. It use to be called "Gas station" dispensing areas, now it is for all fuels. (LP,Natural Gas, etc.) There is also lots of info in the NFPA about LP gas areas. I don't have the NFPA book in front of me, it is in the office. It is funny, but I had to inspect a 1000 gal, LP dispenser just this week. It is on a farm so that they can fill up propane bottles for gas grills.
