The first paragraph of Section 5.3.2.2, second sentence reads, “The impacts associated withseismic and volcanic hazards during range construction are considered less than significantbecause existing warning systems are generally expected to provide sufficient warning of anearthquake or eruption such that personnel and equipment would likely have time to evacuate.”While it is true that some, though by no means all, volcanic eruptions may be anticipated,it is not yet possible to warn of an impending earthquake. It is suggested that the sentenceabove be modified to reflect only the possibility of advance warning of a volcanic eruption.Response: The text in Chapter 5 has been modified to reflect that advanced warning isnot a certainty, but rather a possibility.
