RULE 2 PERMITS Texaco, Inc. 7265 South County Road 9 Craig, Colorado 81625 Pre -blasting surveys and assessments of surface structures have been conducted for eleven power pole foundations and the two residential structures located at 6647 and 7072 MCR 51. Copies of the summary reports are included as Exhibit 14, Items 4 & 5 and are summarized in Section 4.08.2 of this document. Public Notice of Blasting Schedule Colowyo will republish a blasting schedule similar to the one set forth in Volume 1, Section 2.05, Figure 1 — Public Notice of Blasting Schedule. Disposal of Excess Spoil Colowyo will construct two separate "valley fills" which will be called the East Taylor Fill and the West Taylor Fill. These fills are necessary due to the early operation of the South Taylor mining area; overburden will need to be placed into the fills so that sufficient working area can be developed prior to the placement of subsequent overburden into the mined -out areas. Detailed geotechnical investigations were completed for both the East Taylor Fill and the West Taylor Fill by Shannon & Wilson, Inc. A report of the investigations can be found in Exhibit 21 Item 1. Construction plans for the fills, addressing the requirements of Rule 4.09, Disposal of Excess Spoil, can also be found in Section 4.09 and Exhibit 21, Item 1. Locations of the East Taylor Fill and West Taylor Fill can be found in Exhibit 21, Item 1 and on Map 23A. 2.05.4(l) Reclamation Plan The reclamation objective for the South Taylor area is to restore the mined area to a land use capability which will, be equal to or better than that which currently exists. -The first objectives of all reclamation practices are to stabilize the soils, maintain hydrologic and vegetation resources, and to restore the approximate original contour of the mined area. Ultimately, the areas being mined will be returned to their approximate original use as rangeland with watersheds having their approximate pre -mining character. In general, the long term appearance and usefulness of the mine plan area will be similar to that which would have been encountered prior to any mining. The reclamation plan for the existing mining areas provides information relevant to the reclamation of the South Taylor mining area, which can be found in Volume 1, Section 2.05.4. Specific topics requested by the regulations and not incorporated into Volume 1 are included in the following subsections. 2.05.4 (2)(a) Reclamation Timetable The sequence for reclamation following the mining process is shown on Map 29 A. Final reclamation of the South Taylor pit will be delayed, due to the shape, size and depth of the pit; which will result in leaving the majority of the spoil backfilling process until final pit closure. The majority of the spoil will be stacked in the initial boxcut area and associated valley fill areas, allowing adequate space to perform mining operations in a geotechnically safe environment. Colowyo is attempting to reduce the amount of mining related disturbance that is associated with the mining of the South Taylor pit; this also contributes to the situation of stacking spoil material and delaying reclamation, which minimizes the areas impacted by temporary spoil pile placement and concentrates the active mining activities to the existing disturbance boundary for South Taylor. Although the final reclamation of the South Taylor will be delayed due to the South Taylor/Lower Wilson — Rule 2, Page 76 Revision Date: 11 / 18/16 Revision No.: MR -163
