Regulatory Requirements •Secondary containment volume must be sufficient to hold the contents of the tank (EPA/OSHA). •Fire code constraints. •Dynamics not considered! Design Considerations. •Dike height. •Dike diameter. •Dike shape. •Complete tank rupture. •Small hole in tank wall.
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.

Two independent lines one for Sulfuric acid and one for Phosphoric acid from jetty to proposed storage tanks at wharf iii. Flexible hoses connects ship manifold and the unloading lines to the proposed acid storage facility. iv. (a) The following aboveground storage tanks (ASTs) are exempt from regulation under this subchapter: (1) a farm or residential tank with a capacity of 1,100 gallons or less used for storing motor fuel for non-commercial purposes; (2) a tank used for storing heating oil for consumptive use on the premises where stored; (3) a septic tank; Above-ground fuel tanks can also present significant loss exposures in the form of fires, explosion, pollution, and theft. If your company or business has an above-ground fuel tank or is considering installing one, here are some requirements you'll need to consider: Double walled tanks are preferable to single-wall tanks. Structural support from heavy-duty cables and steel D-rings on the primary containment tank allow the Poly Dike MPE to withstand a catastrophic tank failure without moving. The uniquely angled wall strut design prevents material loss and protects against environmental contamination by forcing flow back into the secondary containment dike system and not over the wall.

One tank in the diked area. *Note that the length, width and height of the dike must be measured on the inside, not the outside of the dike. 1). Measure the length
The Piping from or to the tank should not pass from one dyke enclosure to another. 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. I do not have a copy of NFPA-30 available to me, but if memory serves me correctly there is a requirement that if the dike exceeds 6 feet in height then a walkway from the top of the dike to the tank shell is required. In addition, I think a remote means of operating the valves is also required. This same requirement shows up in the OSHA regs also. Minimum requirements of how the urethane cement flooring system must be constructed are listed in 40 CFR 264.193(c) and include: Constructed materials that are compatible with the wastes to be placed in the tank system and must have sufficient strength and thickness to prevent failure. This paragraph establishes the requirements for drainage facilities of dikes for the area surrounding aboveground flammable liquid storage tanks.
Be sloped and curbed to collect liquid. c. Have no drains or openings in dike floor or walls.

Small aboveground storage tanks such as methanol and chemical tanks that have volumes between 1 m 3 and 5 m 3 or, when there volume is included with other volumes stored on site exceed the total volume of 5 m 3 per site must be double-walled or have secondary containment.
