as a reclamation procedure than to backfilling to attain approxi- <br />mate original contour. <br />3. Water diversion and impoundments. <br />One short diversion ditch from one small intermittent <br />stream bed to another will be constructed to divert runnoff from <br />the stockpile areas. See Exhibit C-2 for specific location. A <br />culvert will be placed under the haul road where it crosses the <br />other intermittent stream bed in the permit area. No sediment <br />ponds are believed necessary because runnoff from the disturbed <br />areas will be minimal and there will be no contaminating (toxic) <br />materials utilized or stored in those areas. <br />All natural or diverted water courses will be riprapped <br />and all pad or working areas will be graveled. The quarry itself. <br />is obviously solid rock. All water courses that are diverted <br />will be returned to AOC or designed (rock, meandering; etc.) so <br />as to not change the hydrologic balance of the area. <br />We believe there will be less sediment produced from <br />this area than from premining conditions. <br />4. The size of areas to be worked at any one time. <br />Only one quarry bench will be worked at a time. Bench <br />widths will not exceed 60 feet and the length of the portion <br />being quarried will be approximately 300 feet.' See Exhibit C-5 <br />for planned bench locations for each ten year period for the 90 <br />year life of the mine. All disturbances associated with the <br />actual quarrying of the limestone must be classified as major <br />disturbance. <br />5. Mining operation timetable. <br />The first phase will be site preparation and openinq of <br />the first five year quarry site. This will be accomplished <br />
