where: <br />s~Z=release area variance <br />sZ2 =reference azea variance <br />n, = release area sample size, and <br />nZ =reference area sample size. <br />The results of sampling efforts will be contained in the annual reclamation report. The presentation will <br />include the raw field data, a summary of the analyses, and results of the analyses. <br />On August I5, 1985 (revised December 8, 1986) Basin submitted a rill and gully plan to the Division. <br />Exhibit 26, Rill and Gully Plan, presents a copy of this plan. <br />ealin~ and Managing Mine onenin~s <br />Sealing of the openings which access the underground coal mining operations at the Golden Eagle Mine <br />will be completed upon the fmal closure of mining operations to minimize safety hazards to man and <br />wildlife in theseareas. Atypical mine opening seal is shown on Figure 4. Figure 5, Typical Borehole <br />Seal, shows a typical borehole seal that will be utilized by Basin, except as described in Section 2.05.4 f). <br />f). Reclassification and Transfer of Ventilation Facilities to Industrial Use. <br />Methane degasification wells, airshafts, and open boreholes penetratiryg the underground mine workings <br />• will be reclassified for industrial use. Slroud Oil Company, aka Apache Canyon Gas, L.L.C. will obtain <br />the necessary permits through the State of Colorado, Oil and Gas Conservation Commission to develop <br />methane gas production wells at these locations. <br />Reclamation of these reclassified facilities will be in accordance with the Oil and Gas Conservation <br />Commission regulations. Reclamation bonding for these facilities will be filed with the Oil and Gas <br />Conservation Commission. When the appropriate bonds have been filed, and adequate proof of bonding <br />submitted to the Division of Minerals and Geology, Basin Resources will request bond release for these <br />facilities, and will only be responsible for these facilities to the extent required by Rule 4.15.10 (2). <br />These facilities are listed in Exhibit 19, Bonding Schedule - TR-45, and in Exhibit 31, Industrial Land Use <br />Classification for Methane Gas Production Schedule, and maps TR45-I through TR45-5. <br />2.05.5 Pos[ Mining_Land Uses <br />The post mining land use which Basin proposes for [he permit azea a[ the Golden Eagle Mine shall consist <br />of pastureland, rangeland, ranchette and industrial use (natural gas production). This is identical [o the <br />Premining land use as shown on Map 4, with the addition of industrial use. This is consistent with <br />approved land uses as determined by the Las Animas County Zoning Board. Detailed explanations of each <br />of these land uses which Basin plans to implement on reclaimed lands is located in Section 2.04.3 of this <br />application. <br />(Revised Oi/12/87) <br />(Revised 07/29/94) <br />(Revised 0723/97) ~ ~ <br />• 2.05-27 ~ / <br />/b~Z,~a1 <br />
