A single-wall, double-bottom storage tank placed entirely within a diked area, with an impermeable barrier in the floor of the containment area around the storage tank and in the dike walls, but not underneath the storage tank. Secondary containment shall be in conformance with the following: Used oil storage tanks that are manually filled

= Net dike capacity / volume of largest tank within the dike = 22,473 / 20,000 = 112% This available freeboard volume provides a freeboard height: = Available freeboard volume / dike surface area = 331 ft3 / (60 ft x 36 ft) = 0.15 ft ≈ 1.8 in Therefore, this dike provides sufficient freeboard for 1.8 inches of precipitation.

20,000 20 ft gallons Height: ? 45 ft Given the dike footprint, we want to determine the wall height necessary to provide sufficient freeboard 2020-04-28 • Tanks need to be accessible for firefighting purposes – Slope > 1% away for at least 50 ft. or to dike base – Outside base of dike must be at least 10 ft. away from property line – Dikes > 3 ft.

Dike: a wall or barrier which is Impermeable to a stored substance and which forms the perimeter of the Secondary Containment area. 2.1.12. Double-bottom Tank: a fuel storage tank that has a second bottom Tank System, the Bureau may issue a notice to the Licence Holder Tanks storing Class I, II, III stable liquids shall be separated by the distances given in Table 22.4.2.1. [Table at end of document.] Exception: Tanks used only for storing Class IIIB Liquids need not be separated by more than 3 feet provided they are not within the same diked area as or drainage path of a tank storing a Class I or II liquid. Open area between a high-type dike and the container wall where dike wall height exceeds distance between dike and container walls [See see Figure 10.7.2(c).

This stipulation need not be applied to tanks storing excluded petroleum class.

Effective Alternative to Concrete Containment Dikes · Chemical storage tanks · Hazardous material work areas · Process treatment sites · Rainwater runoff diking 15 Sep 2011 a concrete dike. The tank is 35 feet long by 10 feet in diameter. The secondary containment area provides a 5-foot buffer on all sides (i.e. dike The top view of the Minimum Containment Floor Area. (MCFA) for two vertical tanks used in Example 1.

This creates a confined space entry problem too. Piping connected to tanks should route directly to the outside of the dike enclosure as much as possible to minimize piping within the dyke enclosure. The minimum distance between the tank outer shell and the inside surface of the dyke wall shall not be less than 0.5 times the tank’s height. The dike is then coated with a protective coating to contain liquids in the event of a spill or tank rupture.
