1 To calculate distance d to a public area from NEW:

NEW ≤0.5 lbs: d = 236

0.5 lbs <NEW <100 lbs: d = 291.3 + [79.2 *ln(NEW)]

100 lbs ≤NEW ≤450 lbs: d = −1133.9 + [389 *ln(NEW)]

NEW is in lbs; d is in ft; ln is natural logarithm.

To calculate maximum NEW given distance d (noting that d can never be less than 236 ft):

0 ≤d <236 ft: Not allowed (d cannot be less than 236 ft)

236 ft ≤d <658 ft: NEW = exp [(d/79.2)-3.678]

658 ft ≤d <1250 ft: NEW = exp [(d/389) + 2.914]

NEW is in lbs; d is in ft; exp[x] is e x.

2 The public traffic route distance is 60 percent of the distance to a public area.

d = 18*NEW 1/3

NEW is in pounds; d is in feet

2 To calculate maximum NEW from given intraline distance d:

NEW = d 3/5,832

1 A launch site operator must use the percentage factors of table E-5 to determine TNT equivalencies of incompatible energetic liquids that are within an intraline distance of each other.

2 A launch site operator may substitute the following energetic liquids to determine TNT equivalency under this table as follows:

Alcohols or other hydrocarbon for RP-1

H2O2 for LO2 (only when H2O2 is in combination with RP-1 or equivalent hydrocarbon fuel)

MMH for N2H4, UDMH, or combinations of the two.

3 TNT equivalency for LO2/LH2 is the larger of:

(a) TNT equivalency of 8*W 2/3, where W is the weight of LO2/LH2 in lbs; or

(b) 14 percent of the LO2/LH2 weight.

1 Multiple tanks containing hydrogen peroxide in concentrations of greater than 91 percent may be located at distances less than those required by table E-7; however, if the tanks are not separated from each other by 10 percent of the distance specified for the largest tank, then the launch site operator must use the total contents of all tanks to calculate each intraline distance and the distance to each public area and each public traffic route.

2 A launch site operator may use the equations below to determine permissible distance or quantity between the entries of table E-7:

W >10,000 lbs Distance = 24 * W1/3

Where Distance is in ft and W is in lbs.

To calculate weight of hydrogen peroxide from a distance d:

d >75 ft

W = exp[−134.286 + 71.998*(ln(d)) −12.363*(ln(d)) 2 + 0.7229*(ln(d)) 3]
