2. Mining Timetable <br />The following timetable is a best estimate of the sequence of operations for the life of the mine after <br />March of 2002 and is based on mining and selling 100,000 tons of total product per year (this is less <br />than the permit rates but are expected averages): <br />Task <br /># <br />Description <br />Time Needed <br />1 <br />Finish mining east of existing Berry Pit <br />3 months <br />2 <br />Construct sediment pond in sw corner of disturbed area <br />0.25 months <br />3 <br />Strip soil and overburden from Strip 1 <br />0.25 months <br />4 <br />Mine Strip 1 <br />20 months <br />5 <br />Repeat Tasks 3 and 4 for Strips 2,3,4,5,6,7,8,9 <br />168 months <br />6 <br />Backfill overburden and soil in Strip 9 <br />0.25 months <br />7 <br />Regrade pit area and stockpile area <br />0.5 months <br />8 <br />Retopsoil processing area and stockpile area <br />0.25 months <br />9 <br />Reseed and mulch last 4 strips, processing area and stockpile area <br />0.25 months <br />Total: <br />192.5 months <br />Note: If large contracts are awarded to the site, production could increase to the permit maximum, <br />thereby curtailing the life of the pit. On the other hand, if contracts are less than anticipated, the life of <br />the pit could be extended. This table is based on a reasonable projection of average production rates. <br />3. Hydrology and Sediment Control for Mining <br />No major streams or intermittent streams intersect the disturbed area although the White River is lo- <br />cated a few thousand feet to the south of the permit area. <br />Sediment control for the permit area is provided by a berm on all downstream parts of the permit area, <br />which will have a collection ditch on the inside edge leading to the sediment pond. The berm will be a <br />minimum of 2.0 feet high with 2H:1V sidelsopes. This berm will actually be part of a larger protection <br />Berry Pit 3/02 8 <br />
