Zone 1 contour should ignore SL <=1.7 #210

Closed grgrgrknght closed 9 years ago

based on "damaging blast waves" definition of congestion in api 753. SL 1.7 gives 0.25 psi freefield.

sl 1.7 and fs 0.092 both give 0.25psi, anything lower and the threat does not contribute to the volume calc used to get zone 1 distance
