The tank footprint is equal to ∏D2/4, where D is the tank diameter. 1. Calculate total dike capacity: Total capacity of the concrete dike = length x width x height = 60 ft x 36 ft x 1.5 ft = 3,240 ft3 = 24,235 gallons 2. dikes or catchment basins) must hold 100% of the capacity of the largest contain- er and additional volume for precipitation (40 CFr 112.8(c)(11)). to comply with this requirement, the facility might need to designate an area of the installation •synthetic membrane under the tank •double-walled tank (shop fabricated) •double bottom tank (field erected) Temporary tanks . Temporary tanks are ASTs located at a facility for more than 30 days, but less than one year.

These worksheets address four specific scenarios and may not be valid for every facility.

dike with a 110% capacity of the tank may be acceptable depending on, the shell size of the tank, local precipitation patterns and frequency of containment inspections. In a different geographic area, a dike or berm designed to hold

STANDARD FEATURES. Unique shell design eliminates as many weld seams as possible for max leak protection *Two Tank Containment Design* Tanks shall be arranged in a maximum of two rows. Tanks having 47,700 cu.m capacity and above shall be laid in a single row.

dike with a 110% capacity of the tank may be acceptable depending on, the shell size of the tank, local precipitation patterns and frequency of containment inspections. In a different geographic area, a dike or berm designed to hold Step 1: Multiply the size of your largest tank (in gallons) by the number indicated to obtain the minimum amount that your dike is required to hold in gallons: (Please note that if you have 2 or more tanks siphoned together, you must use the total gallons of all tanks siphoned together.) ___ _____ __ x … g.

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.

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.
