During the next five-year permit term Trapper will not conduct blasting operations within 1,000 feet of any <br />building used as a dwelling, public building, school, church or community or institutional building outside <br />the permit area or within 500 feet of an active or abandoned underground mine. As such, the anticipated <br />blast design required by 4.08.1(4) will not be submitted for the next five-year term. <br />Flyrock, including blasted material traveling along the ground, will not be cast from blast sites more than <br />half the distance to the nearest dwelling or other occupied structure and in no case beyond lines of <br />property owned or leased by Trapper, or beyond the area of access regulated by Rule 4.08.4(5). <br />Within the Trapper permit area, blasting will never occur simultaneously at two or more pits. <br />All blasting will be conducted to prevent personal injury and damage to property. Blasting will be <br />conducted in such a manner as to ensure compliance with the ground vibration limits set forth in Rule <br />4.08.4(10). Blasting will be conducted in accordance with the following equation: <br />W = (D/DS)2, where <br />W = the maximum weight of explosives, in pounds, that can be detonated in any 8 - <br />millisecond period during a blast; <br />D = the distance, in feet, from the closest blast hole to the nearest dwelling, public <br />building, school, church, or community or institutional building; <br />Ds = the scaled -distance factor, using the following values as described in Rule <br />4.08.4(10): <br />50 = when the distance from the closest blast hole to the nearest dwelling, <br />public building, school, church, or community or institutional building is 0 to 300 <br />feet; <br />55 = when the distance from the closest blast hole to the nearest dwelling, <br />public building, school, church, or community or institutional building is 301 to <br />5,000 feet; <br />65 = when the distance from the closest blast hole to the nearest dwelling, <br />public building, school, church, or community or institutional building is 5001 feet <br />or greater. <br />3-31 a <br />Ca <br />
