Ala. Admin. Code r. 400-3-6-.07
All permanent tanks, tank outlets, treaters, or other facilities used to store salt water, must be surrounded by a dike constructed with impermeable material. The containment area surrounded by the dike shall be lined with impermeable material. The containment area shall have a capacity of at least one-and-one-half (1 1/2) times that of the tank or other vessel containing fluids and in any event the dike shall be at least two (2) feet high on the inside wall unless otherwise approved by the Supervisor. The Supervisor may require dikes around other facilities that contain salt water or other fluids. In the case of tank batteries, the dike must have the capacity to contain a volume equal to one-and-one-half (1 1/2) times that of the largest tank in the battery and in any event the dike shall be at least two (2) feet high on the inside wall unless otherwise approved by the Supervisor. The top of the dike must be at least two (2) feet higher than the bottom of the lowest tank or other vessel containing fluids. The tanks or other vessels containing fluids must be elevated to provide enough gradient to allow drainage away from the tanks toward the dike. No salt water shall be allowed to remain within containment areas. Drainage of fluids from containment areas shall be authorized by appropriate permit(s) or regulations.
