r~ <br />MINING PLAN <br />Nining of each phase, I thru VI, will begin with the <br />stripping of approximately 1' of top soil and vege- <br />tation. This material will be stockpiled primarily <br />around the perimeter of the pits for later use. No <br />soil stockpiles will be placed in the Boulder Creek <br />floodway. <br />These stockpiles, which will be approximately 10' high, <br />will act as a sound barrier between the mining operation <br />and the residents. As these piles are soil and vege- <br />tation, it is anticipated that they will quickly be <br />covered with new growth, thereby acting as alust <br />preventative. <br />The area to be mined will be trenched by dragline and <br />dewitered. The water will be discharged to Boulder <br />Creek or its irrigation ditches, under the authority of <br />an :N.P.D.k;.S. permit. The discharged water will be <br />monitored daily and regulated to prevent flooding of <br />downstream lands. <br />A portable crusher spread will be located near the area <br />to oe worked to crush, size and stockpile the gravel. <br />Thereby reducing travel distance of the loaders. <br />The gravel stockpiles and plant will not be positioned <br />in the floodway. These stockpiles will be positioned <br />bet~deen the mining operation and the residents as an <br />add~:d measure of sound protection, and the haul roads <br />will be wetted for dust suppression. <br />The gravel mined is in a damp state, however, the <br />pro~~essinq equipment is fitted with spray bars and <br />these are kept is use during operations. The water <br />for dust suppression will be imported until a local <br />source, properly decreed, is obtained. <br />Five to sixteen feet of((Aluvium will be remove3from each <br />pha:;e, beginning with Phase I and proceeding thru Phase <br />VI. This operation is expected to last lU years, however, <br />market conditions dictate the amount of material to be <br />removed from this site. <br />Gravel trucks will enter <br />loc~stions from the count <br />approval from the county <br />• :destern Paving maintains <br />~ trur_kinq operations. <br />and exit the mine at multiple <br />y road system - see letters of <br />and state road departments. <br />very strict control over its <br />
