Swimming Platforms vs. Docks

[bthouse]

Our client owns a resort on a lake. They currently have a floating dock for swimming. This dock has 120v lighting as well as a 240v pump connected to the irrigation system. Why the pump is on the dock and not the shore is beyond me, but that's something we'll address later. The facilities manager says that the code states that no power above 12v can be within 250ft of a "swimming platform". He wants the lighting and the pump changed to 12v. Yeah.......a 12v irrigation pump. My question is has anyone heard of any code requirements relating to a "swimming platform"? Article 555 covers docks. Article 680 covers swimming pools, but I have not been unable to find anything in the code book or online that differentiates between a swimming platform and a floating dock. This guy is kind of a dick, so I want to be sure I'm not missing something before I question where he got his information. As a side note, this "swimming platform" in on Lake of the Ozarks which is maintained by the Army Corps of Engineers and Ameren UE. Ameren UE is who enforces electrical code requirements for docks on this lake. Ameren's dock requirements manual makes no mention for any requirements that differ from a boat dock.

Highly likely it's a valid "rule" as many States have adopted standards in regard to swimming at docks, etc.
In ''17 the NEC added 555.24 and in '19 the State of TN adopted a new law for boat docks including signage:
(3) Install permanent safety signage with print legible at eighty feet (80') of distance and placed to give adequate notice, to persons using the boat dock or marina or swimming area near the boat dock or marina, of the electric shock hazard risks of the waters around the boat dock or marina. The signage shall state: “ELECTRIC SHOCK HAZARD RISK: NO SWIMMING WITHIN 100 YARDS OF THE BOAT DOCK”.

Whether or not it a code violation, supplying 120V to a floating swimming platform sounds crazy to me. What could possibly go wrong?

Have you contacted the Ameren UE inspector, to determine what 'rules' that they enforce?

The pump maybe on the dock so it's close to the source water they use for irrigation.

Sounds like one of these things....
