Figure 1 provides an overview of the application of this report to existing establishments. The Poly Dike’s flexible, modular design is coupled with wall heights varying from 12 inches to 30 inches to meet capacity requirements. Note, when determining system size, the base of the Poly Dike wall varies in width from approximately 12 inches to 27 inches depending on wall height. Bunding is a legal requirement in many countries, particularly around tanks, storage vessels and other plants that contain liquids which may be dangerous or hazardous to the environment.

REGISTRATION REQUIREMENTS Required for all USTs and ASTs larger than 1,100 gallon capacity. EPA Requirements for Tank Systems The EPA specifies under 40 CFR part 264.193(b) that secondary containment systems are required to prevent any migration of wastes to soil, ground water or surface water during the use of the tank system. • Capacity * The volumetric capacity of the diked area shall not be less than the greatest amount of liquid that can be released from the largest tank within the diked area, assuming a full tank.

So, there will be only one Dike Encloser/Tank Farm. The capacity of the diked enclosure shall be calculated by deducting the volume below the height of the dike of all tanks within the enclosure. 1926.152 (i) (2) (vii) (C) (3) Walls of the diked area shall be of earth, steel, concrete or solid masonry designed to be liquidtight and to withstand a full hydrostatic head. Aboveground storage tank regulations define a bulk storage container as any container having a capacity of 55 gallons or more and can be aboveground, partially buried, bunkered, or totally buried.

Tanks arranged in groups with a total capacity not exceeding 500,000 gallons (1892 500 L) may be enclosed in a single dike wall enclosure. Each group tank dike area shall have a net capacity not less than that of the largest tank plus 10 percent of the aggregate capacity of all other tanks served by the dike enclosure. Regulatory Requirements •Secondary containment volume must be sufﬁcient to hold the contents of the tank (EPA/OSHA).

g. Be anchored unless the tank level is higher than the dike wall. 3. Dikes/containment must: a. Have capacity at least 100% of the size of the largest tank plus displacement of everything stored in dike (+ 6” extra if dike is not covered). b. Be sloped and curbed to collect liquid. c. Have no drains or openings in dike floor or walls. d.

Tanks also require liquid level gages and to alert attendant during unloading when tank reaches 90% of capacity alarm and stop product flow when the tank reaches 95% of capacity. The transport must be at least 25 feet from the tanks when unloading gasoline and 15 feet with diesel.

Therefore these tanks have to be installed at a minimum specified distance from other facilities. In order to contain spills and leakages dikes have to be built around above ground storage tanks. The free volume enclosed by the dikes should generally be 110% of the volume of the tanks.
