Cuttings samples will be obtained and described. Drilling depths will range from a projected 300 to 685 feet. Total depth of each hole will be below the targeted `B' seam. Detailed down hole geophysical logs will be obtained at each hole. Coring may be conducted at some of the holes. All drill holes will be grout- cemented through coal- bearing strata, with cement extending 50 feet above and below the mineable coal bed. The remainder of the hole will be backfilled with cuttings and mud to ten (10) feet or greater below the surface. The hole will then be grout - cemented to the surface. An aluminum or brass marker will be cemented into the top of each hole extending less than 8" above the reclaimed surface. These markers will have the hole identification number scribed or stamped. Reclamation of disturbed areas will be initiated and completed shortly following site abandonment. Drill sites will be recontoured and seeded. Seed rates of pounds per live seed per acre for broadcasting are shown in Section 9.2 of the Federal Coal Exploration License application. Access routes that did not previously exist will be scarified as needed and seeded. Water bars will be constructed where necessary. Cuts will be pushed back to approximate original contours and any trees removed during construction scattered over the access route to deter future use. Item #5 b. 1) Drill sites are located on fairly flat to gently sloping ground. These sites will be approximately 75' X 120', or 0.201 acres each plus mud pit for a total of 0.23 acres per location. Topsoil will be salvaged from the drill sites and mud pit locations and stored immediately adjacent to the site. No topsoil salvage will occur along the access route. 2) Drill sites will be located on relatively flat areas. An average of approximately 100 CY of material will be moved during drill site construction (1500 CY total). The new access routes were sited to minimize the need for earth moving. Access to most sites will require negligible earthwork. We estimate that access will require a total of about 200 CY of cut and fill. 3) Seed rates of pounds per live seed per acre for broadcasting are shown in Section 9.2 of the Federal Coal Exploration License application. This seed mix is based on the mix used at the adjacent Deserado Mine. Changes from this proposed mix may be made at the request of the BLM. 4) The depths of the proposed drill holes can be found in the table provided above. 5) Prior drilling in the area indicated no presence of a groundwater aquifer. Any groundwater encountered was very limited in extent indicating origination from an aquiclude. We do not anticipate encountering an aquifer with the proposed drilling. 6) All drill holes will be grout- cemented through coal- bearing strata, with cement extending 50 feet above and below the mineable coal bed. The remainder of the hole will be backfilled with cuttings and mud to ten (10) feet or greater below the surface. The hole will then be grout- cemented to the surface. An aluminum or brass marker will be cemented into the top of each hole extending less than 8" above the reclaimed surface. These markers will have the hole identification number scribed or stamped.
