" • <br />CF&I Steel Corporation <br />Dolomite Quarry <br />Permit M-77-376 <br />Revised Mining Plan <br />January 20, 1987 <br />C; <br />All future active mining operations will be limited to the current quarry floor <br />(see attached map). No new areas will be disturbed by future mining activity. <br />A single access / haul road will be maintained to the site. Operation of the <br />quarry will be in conformance with the current plan except for the limited area <br />of operation. <br />Conventional methods of drilling and blasting will be used to mine the dolomite <br />formation only within the boundary of the proposed active operation. Crushing, <br />screening and stockpiling of the mineral will be done on the quarry floor and <br />will continue until all marketable minerals within the area are depleted. <br />Crushed and screened stone will be loaded from the stockpiles and hauled away <br />over the access/haul road. Fine materials resulting from the crushing and <br />screen operations will be used as a topsoil substitute in the reclamation of <br />the active and inactive areas of the quarry. Initially these fines will be <br />used immediately for reclaiming inactive areas. When the inactive areas are <br />reclaimed, fines will be stockpiled only on the quarry floor until required for <br />final reclamation. As any area becomes depleted of marketable stone or is no <br />longer needed for operations, it will be reclaimed. <br />
