Determining How Much Secondary Containment You Need

All fuel tanks, oil drums, etc. must have secondary containment that equals a minimum of 110% of the largest tank. If your fuel tank is 1,000 gallons, you would need 1,100 gallons of secondary containment. Example: When you have two tanks side by side, one 300 gallons and the other 500 gallons, you would need 110% of the largest tank or 550 gallons. Secondary containment must consist of compatible, nonreactive materials to those being contained. Containment can consist of such things as a livestock water trough for containers of 5 to 55 gallons, a cement pad with cinder block walls sealed with two coats of latex paint, manufactured double wall tanks, poly tanks cut in half, a recessed cement floor with cement berm, etc. Outdoor containment areas must have a spring-loaded valve that is pulled open by hand and closes when released to drain accumulated rain water. Fuel tanks should be located at least 50 feet away from any other structures or environmentally sensitive areas.


1 cubic foot = 7.48 gallons

1000 gallon tank needs 1100 gallons of secondary containment

Determining cubic feet (cf) from gallons: 

1cf  cf  
7.48 gals     x 1100 gals = 0.134 cf/gal x 1100 gals = 147 cf of secondary containment are needed (minimum)
Possible containment areas include:   7 ft wide x 14 ft long x 1.5 ft high = 147 cf of containment OR
6.5 ft wide x 12 ft long x 2 ft high = 156 cf of containment

500 gallon tank needs 550 gallons of secondary containment

Determining cubic feet (cf) from gallons:

1cf cf  
7.48 gals     x 550 gals = 0.134 cf/gal x 550 gals = 74 cf of secondary containment are needed (minimum)
Possible containment areas include:   6 ft wide x 10 ft long x 1.25 ft high = 75 cf of containment; OR
8 ft wide x 10 ft long x 1 ft high = 80 cf of containment
