TR-07 MINING PLAN Access Routes to Mining Areas: Besides the established, existing roadways that provide access for all parties to various portions of the property, separate access routes may be required to mining locations that are not adjacent to or very near existing, established roads. Within the remaining mining area, roads should be located such that they do not cause unnecessary division of reclamation areas. Reclamation should preferably occur in large tracts that can remain undisturbed. REQUIREMENT 6-FUEL STORAGE REQUIREMENTS-APPLIES TO ALL LOCATIONS: Temporary and more permanent fuel storage areas must be properly located and protected. l. No fuel storage may occur in or near a drainageway where floodwaters could potentially reach the storage location. 2. All storage tanks will be surrounded by a properly sized berm. 3. The basin where the storage tank is placed will be sealed with a durable plastic liner or other impermeable and durable material so as to avoid spills from leaking into the ground or escaping the containment berm. 4. The liner material will be frequently inspected to insure rips and tears are repaired and the integrity of the liner is maintained. Mining Process Sequences: In general, mining in all areas will follow a similar sequence. First is removal of the soil, then the overburden, and then the underlying sand. Soil and overburden stockpiling will occur near or adjacent to the mining areas so as to reduce the costs of backfilling and replacement of the soil. More details on this sequence will be provided further on in this plan. Problems Associated with Intermittent Deposits: As described in a previous section of this exhibit, the sand deposits exhibit a non-uniform distribution. This is a result of the fact that the sand was deposited by a blend of alluvial deposition in broadly meandering streams on a multitude of erosion surfaces as well as windblown sand deposited in protected areas in the landscape that was present at that time. Because all of these variations could not conceivably be defined in exploration without very extensive surface disturbance, the mining must adapt to whatever variability is found. Unfortunately, as has occurred in the past, this can create a patchwork mining pattern. In the past it has been found that very good deposits can abruptly come to an end over a matter of a few tens of feet. But careful examination can sometimes show the good deposit heads off in a different direction. On the other hand, it may end and may not continue in any direction. This probably occurs because the multiple erosion surfaces interacted with each other and sometimes an excellent deposit in one area was removed in an adjacent area by a subsequent erosion cycle which was followed by deposition of a different type of material at a different time. Therefore, mining will begin at known locations of good sand. Usually, a backhoe is used to dig holes at a closer frequency than the initial exploration holes. These additional holes help define the Coal Creek Sand Resource Amendment 3 (2005)- M-1988-044 Exhibit D Page 9
