D = 2.68 x 24.49 = 65.6

D = 66 ft

The formula for determining the height of a firewall based on the diameter is:

H=

C

+ 1

(D / 2.68)

H=

3,000

+ 1

(65.7 / 2.68)

H=

3,000

+ 1

(24.51)

H = 4.99 + 1 = 5.99

H = 6 ft

Another important factor to be considered when constructing a berm is the amount of soil required. Figure 3-2

identifies the general dimensions that must be considered when using the formula below. Figure 3-3 and

Table 3-1, identify more specific dimensions for given tank sizes. The formula for determining the amount of soil

required for a particular sized berm is:

V=AxL

A = W + B (h)

2

V=

W + B (h) L

V (cubic yards) = V
