Arizona RV Sewer Law All Hosed Up

We pulled into a Passport America RV park in Benson, Arizona for an overnight stay. The owner pointed out that if I chose to deploy my sewer line it had to be elevated off the ground and connected with an air tight fitting leading into the sewer drain. He told me it was an Arizona law that was passed a few years ago but had not been enforced until recently. He pointed to this sign on the wall and told me that an RVer at a nearby Escapee park had received a $400.00 fine for not properly deploying his sewer hose. When overnighting it I generally don't deploy the sewer hose until I dump in the morning so it didn't effect me. Poking around on the internet I discovered it is also a law in Florida. However, I couldn't find information to collaborate whether this is an actual state law. If you know of other states where this is an actual requirement and also happen to know the legal code or statute number for this law please click on the blue "comments" link below and tell us. I'm awaiting an email reply from the Arizona Secretary of State to clarify this issue and I will post an update here when I receive an answer.
