28 Sep 1994 complying with the Petroleum Bulk Storage(PBS) regulations, all tanks which have a capacity of ten thousand (10,000) gallons or more; and Secondary containment systems are engineered dikes, curbs, liners or diversi

When multiple tanks share a common bund or dyke wall, the capacity is based on the largest tank. Most common designs for large tanks is a concrete or masonry wall around the tank with a concrete floor. Hence bund wall or dyke wall calculation is very important for any plants which stores chemicals / hydrocarbons or liquids in tanks.

Using the formula above, you can easily figure out the dimensions your Collapse-A-Tainer has to be in order to have enough sump capacity. •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. Secondary containment areas for temporary tanks must meet the volume requirements described above, and be 2000-06-09 · Question: Are dikes/barricades required for a 1000 gallon, double-walled diesel storage tank?
