2.05.3(2) <br />• It may be necessary because of coal quality <br />considerations, to mine from Area 1 and Area 2 concurrently. The <br />stockpile volume for topsoil is designed to anticipate this worst <br />case 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 <br />reclaimed 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, shows <br />the progression of production, open pit mining in one year <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 one year increments. For the purposes of this schedule, <br />reclamation is defined as areas where topsoil has been placed on <br />regraded overburden. <br />The following schedule shows acreage to be disturbed <br />initially and at the end of each one year period thereafter, the <br />• reclaimed acreage and the remaining disturbed acreage at the end of <br />each year. <br />Remaining <br />Acreage Reclaimed Disturbed <br />Disturbed Acreage Acreage <br />Initial Disturbance 52 0 52 <br />Month <br />1-12 21 39 34 <br />13-23 71 64 41 <br />24-36 65 58 48 <br />37-48 39 75 12 <br />Ponds & Access Roads 0 12 0 <br />Totals 248 246 <br />• <br /> 2.05-4 May 1992 <br />
