developed during our site visit was correlated with the figure provided in the Lyman and Henn <br />work. <br />The results are summarized in Table I. Particle velocities and particle accelerations <br />ranged from 0.088 inches per second (0.014-0.144 G's) at the NPW storage taril: to 0.606 <br />inches per second (0.99-0.986 G's) at the solids and control buildings for the quarry (Q) blasts. <br />Particle velocities and particle accelerations ranged from 0.227 inches per second (0.037-0.370 <br />G's) at the NPW storage tank to 3.628 inches per second (0.59-5.9 G's) at the solids building <br />for the production (P) blasts. Particle velocities and particle accelerations ranged from 0.198 <br />inches per second (0.032-0.322 G's) to 1.490 inches per second (0.242-2.42 G's) at the control <br />building for the access road (A) blasts. <br />The particle velocities and particle accelerations were estimated for the lighting <br />facilities and aze summarized in Table II. Particle velocities and particle accelerations of 4.00 <br />inches per second (1.304-9.771 G's) for the (Q) blasts and 47.649 inches per second (15.5- <br />116.2 G's) for the (P) and (A) blasts were estimated. <br />CONCLUSIONS/RECOMMENDATIONS <br />Our analyses indicated similar results to the analyses performed by Lyman and Henn. <br />The major difference being that we had access to the wastewater treatment facility and were <br />able to determine the distances to the various structures. Lyman and Henn and the State of <br />Colorado both used a particle velocity of 0.75 inches per second as the limiting velocity. As can <br />be seen both by our analyses and Lyman and Henn's analyses that the threshold velocity is <br />exceeded in the blasting for the production (P) and the access road (A) for the wastewater <br />treatment facility and the threshold velocity is exceeded for the lighting facilities for the quarry <br />5 <br />
