1 <br />' 8.3 Drilling Procedures <br />.A Westerr. Fuels' geologist :vil] be assigned to the drilling unit and will be on <br />' site during all field opersticns. <br />' The drill hole locations will be prepared by removing vegetation and topsoil from <br />the drilling site. Vegetation and topsoil will be segregated so that during site <br />' reclamation, topsoil can be placed back on the location and the vegetation spread <br />back over the topsoil, see Section 11(f). Mud pits to contain drilling Pluids <br />will be constructed adjacent to the drill pad as stipulated in Section 11(i). <br />Holes will be drilled with 5-1/4 or 5-5/8 inch diameter bits using air with mist <br />injection and/or water and drilling mud as dictated by hole conditions. Cuttings <br />' samples will be obtained and described. Drilling depths will range from 980 feet <br />to about 1895 feet. Total depth of each hole will be st least 20 meters below the <br />deepest mineable ccsl. Coring is not anticipated at this time; however, detailed <br />down hole geophysical logs will be obtained at each hole. The estimated depths <br />' for each hole sre shown in Table 8-1. <br />' 9.0 RECLA:t4.4TION PROCEDURES <br />9.1 Drill Hole Plugging <br />1 <br />All drill holes will be grout-cemented through coal-bearing strata, with cement <br />' extending 50 feet above and below the mineable coal bed. The remainder of the <br />hole will be backfilled with cuttings and mud to ten (10) Peet below the surface. <br />' The hole will than be grout-cemented to the original ground surface. A 2 to 3 Pt. <br />length of casing will be cemented into the top one foot of each hole and will <br />' serve ss the hole monument. Aluminum caps marked with the hole identification <br />number will be cemented into the top of the hole monument, see Section I1(m). <br />' 9.2 Surface Reclamstior. <br />' Reclamation of disturbed areas will be initiated following site abandonment in <br />late summer or fall. Drill hole sites will be recontoured, disked and seeded as <br />' stipulated, see Section 11(k). <br />9 <br />
