§ 64.76 TANKS.
   64.76(A)   Underground tanks. Underground tanks in Flood Hazard Areas shall be anchored to prevent flotation, collapse or lateral movement resulting from hydrodynamic and hydrostatic loads during conditions of the Design Flood, including the effects of buoyancy assuming the tank is empty.
   64.76(B)   Above-ground tanks, not elevated. Above-ground tanks that do not meet the elevation requirements of § 64.76(C) shall be permitted in Flood Hazard Areas provided the tanks are anchored or otherwise designed and constructed to prevent flotation, collapse or lateral movement resulting from hydrodynamic and hydrostatic loads during conditions of the Design Flood, including the effects of buoyancy assuming the tank is empty and the effects of flood-borne .
   64.76(C)   Above-ground tanks, elevated. Above-ground tanks in Flood Hazard Areas shall be attached to and elevated to or above the Design Flood Elevation on a supporting that is designed to prevent flotation, collapse or lateral movement during conditions of the Design Flood. Tank-supporting shall meet the foundation requirements of the applicable Flood Hazard Area.
   64.76(D)   Tank inlets and vents. Tank inlets, fill openings, outlets and vents shall be:
   64.76(D)(1)   At or above the Design Flood Elevation or fitted with covers designed to prevent the inflow of floodwater or outflow of the contents of the tanks during conditions of the Design Flood; and
   64.76(D)(2)   Anchored to prevent lateral movement resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy, during conditions of the Design Flood.
