26a Standards for Residential Structures

Flotation Devices and Material

  1. Flotation for all docks, boat mooring buoys, and other water-use structures and facilities must be of materials commercially manufactured for marine use. Flotation materials must not become waterlogged, crack, peel, fragment, or be subject to loss of beads. They must be resistant to puncture, penetration, damage by animals, and fire. Any flotation within 40 feet of a line carrying fuel shall be 100% impervious to water and fuel. Styrofoam flotation must be encased. The reuse of plastic, metal, or other previously used drums or containers for encasement or flotation purposes is prohibited.

    Existing flotation that is in compliance with previous rules is authorized until in TVA’s judgment the flotation is no longer serviceable, at which time it must be replaced with approved flotation upon notification from TVA.
  2. Because of the possible release of toxic or polluting substances and the hazard to navigation from metal drums, their use in any form is prohibited.
  3. Every flotation device employed in the Tennessee River system must be firmly and securely affixed to the structure it supports with materials capable of withstanding prolonged exposure to wave, wash, and weather conditions.
