2 .05 . 3 ( 2) <br /> It may be necessary, because of coal quality considera- <br /> tions , to mine from Area 1 and Area 2 concurrently. The stock- <br /> pile volume for topsoil is designed to anticipate this worst case <br /> scenario . If Area 2 is mined in sequence after Area 1 , the <br /> topsoil stockpile for Area 2 will not have to be as large because <br /> some of the topsoil stripped from Area 2 will be placed on re- <br /> claimed portions of Area 1 . The volume of the temporary spoil <br /> pile for Area 2 will remain the same for either case. <br /> The initial phase of the operation is expected to take <br /> approximately one month. The Mine Plan Map, Drawing No . 115 , <br /> shows the progression of production, open pit mining in six 'month <br /> intervals. The projected schedule assumes a production rate of <br /> 350,000 tons per year and that Area 2 is mined sequentially after <br /> Area 1 . The schedule will change if production varies from that <br /> estimated. <br /> The Mine Plan Map also shows the progression of recla- <br /> mation in six month increments . For the purposes of this sched- <br /> ule , reclamation is defined as areas where topsoil has been <br /> placed on regraded overburden. <br /> The following schedule shows acreage to be disturbed <br /> initially and at the end of each six month period thereafter, the <br /> reclaimed acreage and the remaining disturbed acreage at the end <br /> of each six month period. <br /> Remaining <br /> Acreage Reclaimed Disturbed <br /> Disturbed Acreage Acreage <br /> Initial Disturbance 47 0 47 <br /> Month <br /> 1-6 16 13 50 <br /> 7-12 14 13 51 <br /> 13-18 29 27 53 <br /> 19-24 16 17 52 <br /> 25-30 27 30 49 <br /> 31-36 34 31 52 <br /> 37-42 30 29 53 <br /> 43-48 32 38 47 <br /> 49-54 15 18 44 <br /> 55-60 0 31 13 <br /> Ponds & Access Roads 0 13 0 <br /> Totals 260 260 <br /> 0 2.05-4 July 1991 <br />
