-~ These estimated peak particle velocities aze well below even the most conservative vibration criteria for <br />damage defined by either the Office of Surface Muvng (OSM) or the United States Bureau of Mmes <br />(USBM). The four structures in the table were chosen due to their proximity to the proposed quarry <br />and the fact that all other structures aze at greater distances. <br /> <br />The next table is inserted to examine the calculated particle velocities and •subsequent pounds of <br />explosives per delay that aze theoretically possble utilising a scaled distance of 65, which is the <br />allowable scaled distance set forth by the OSM for structures between 300 - 5,000 feet from a quarry. <br />LOCATION DISTANCE FRM <br />BLAST EXPLOSIVES PER <br />DELAY BS PREDICTED PPV <br />P.S. <br />STATE PARK 2,750 1,790 0.20 <br />WOOTEN RES. 3,100 2,275 0.20 <br />CLARK RES. 4,350 4,479 0.20 <br />CLEM RES. 5,350 6,775 0.20 <br />The pounds of allowable explosives per delay utilising a scaled distance of 65 is extremely high.
