PROTECTION OF TANKS IN FLOOD AREAS
§ 14a.211. Scope.
The provisions of § § 14a.211—14a.217 (relating to protection of tanks in flood areas) apply for the protection of tanks containing flammable or combustible liquids that may become buoyant due to a rise in the level of the water table or due to their location in an area that may be subjected to flooding.

§ 14a.212. Aboveground tanks.
(a) Each vertical tank shall be located so that its top extends above the maximum flood stage by at least 30% of its allowable storage capacity.
(b) Horizontal tanks located so that more than 70% of the tank’s storage capacity will be submerged at the established flood stage shall be anchored; attached to a foundation of concrete or of steel and concrete of sufficient weight to provide adequate load for the tank when filled with flammable or combustible liquid and submerged by flood water to the established flood stage; or adequately secured from floating by other means. Tank vents or other openings which are not liquidtight shall be extended above maximum flood stage water level.
(c) A dependable water supply shall be available for filling an empty or partially filled tank, except that where filling the tank with water is impractical or hazardous because of the tank’s contents, tanks shall be protected by other means against movement or collapse.
(d) Spherical or spheroid tanks shall be protected by applicable methods as specified for either vertical or horizontal tanks.

§ 14a.213. Underground tanks.
(a) At locations where there is an ample and dependable water supply available, underground tanks containing flammable or combustible liquids, so placed that more than 70% of their storage capacity will be submerged at the maximum flood stage, shall be so anchored, weighted or secured as to prevent movement when filled or loaded with water and submerged by flood water to the established flood stage. Tank vents or other openings which are not liquid tight shall be extended above maximum flood stage water level.
(b) At locations where there is no ample and dependable water supply or where filling of underground tanks with water is impractical because of the contents, each tank shall be safeguarded against movement when empty, and submerged by high ground water or flood water by anchoring or by securing by other means. Each such tank shall be so constructed and installed that it will safely resist external pressures if submerged.

§ 14a.214. Water loading.
The filling of a tank to be protected by water loading shall be started as soon as flood waters are predicted to reach a dangerous flood stage. Where independently fueled water pumps are relied upon, sufficient fuel shall be available at all times to permit continuing operations until all tanks are filled. Tank valves shall be closed and locked in closed position when water loading has been completed.

(b) If an underground tank is taken out of service for a period exceeding 3 months, the fire marshal shall be notified and the following procedures apply:
(1) Comply with the requirements of subsection (a), except that all flammable or combustible liquids shall be removed and the tank completely filled with water. Note that the owner is responsible for ensuring that the tank remains completely filled with water until such time as it is returned to service, removed or abandoned in place.
(2) Comply with § 14a.27 (relating to leaking underground tanks) in cases of tanks that are leaking or incapable of maintaining full capacity of water.
