<br />• Phase 4 Area B3 will be quarried for limestone. Due to the dip of <br />the limestone bed and the steep grade of the terrain it will <br />be necessary to have a 20 to 25 foot bench in the quarry at <br />this point. Overburden from Area B4 will be stripped and <br />backfilled into Area B2 and used to construct the necessary <br />roads to transverse the quarry bench and also to eliminate <br />the resulting high wall between Area B2 and B3. The over- <br />burden will be backfilled in Area B2 along the high wall <br />and contoured to a slope of 2 to 1 or less. <br />The high calcium limestone will be removed from Area B4 <br />using conventional open pit drilling and blasting methods. <br />The limestone will he loaded into trucks and hauled to the <br />stockpile area for sizing and stockpiling. <br />This phase will require approximately 36 months and the dis- <br />turbance will be approximately: <br />Major - 3.25 acres <br />Moderate - 1.25 acres <br />Minor - 0 <br />• <br /> <br />
