Miscellaneous <br />An employee/storage trailer and fueling/lubricating station will be located on-site. <br />Dewatering pumps and generators and watering trucks will be used as needed. <br />As mining progresses through each phase, topsoil and overburden will be stripped with scrapers <br />to expose the aggregate product below. All soil and overburden material will be used for <br />reclamation, so long-term stockpiling of these materials is not anticipated. If overburden <br />stockpiles are necessary, they will be located within the proposed mining areas and placed so that <br />they do not impede potential floodwaters. <br />Mining of the aggregate will progress down to the underlying claystone bedrock. The bedrock <br />material is rippable and, when necessary, will be excavated and used for reclamation. However, <br />since reclamafion will occur concurrently with mining, it is not anticipated that bedrock material <br />will be stockpiled long-term prior to use. <br />The active mining face will extend no more than 2,000 feet in length. During mining and prior <br />to reclamation, the mine walls will be a neazly vertical to ''/aHa V slope. The aggregate material <br />will be temporarily stockpiled or placed directly onto a conveyor system for transport. The <br />conveyor system will transport the material to be processed at an existing DMG pemutted <br />mining site (Permit Number M-89-120) immediately east of the property. The conveyor will <br />cross the South Platte River within the permit boundary before entering the adjacent mining site. <br />as illustrated on the Pre-Mining/Mining Plan Map (Exhibit C). Alternatively, if needed, material <br />may be processed on-site with portable and temporary screening, crushing, andlor washing <br />equipment. <br />Each mining area will be reclaimed using soil, overburden, process fines and other inert <br />materials from on-site. If materials from off-site are used, the applicant will provide the Division <br />with the appropriate notices and affidavit in accordance with Rule 3.1.5(9). During reclamation, <br />mining areas 1, 2, and 3 will be backfilled to create wetlandlriparian areas, whereas only the <br />exterior walls of Ponds 1, 2, and 3 will be backfilled to create reservoir slopes. <br />In Ponds 1, 2, and 3, the active mining face will remain disturbed until the mine area is mined <br />out. The side slopes of the ponds will be backfilled, graded to a 3H:1 V slope, and seeded as <br />mining progresses. The exterior slopes where backfilling and grading has been started, but has <br />not yet been completed, will be no greater than ],000 feet in length. Once backfilling and <br />grading has been completed in an area, the top of the slope and the side slopes above the <br />anticipated reservoir water level will be seeded as soon as practicable (based on first available <br />seeding season). <br />In order to gain an understanding of the extent of the mining operation, it is helpful to know the <br />acres disturbed by different aspects of the mining operation. Each aspect is listed in the <br />following table with associated disturbed area. The table illustrates a point in time where the <br />mining disturbance will be at its maximum. This occurs during the mining in Phase III. The <br />mining disturbance will be at its greatest when the southern section of Pond 3 has been mined <br />and mining is progessing to the northern part of the pond. During this phase, reclamation of <br />mining azea 1 will also be in progress. The area will have been backfilled for reclamation, but <br />Wanenberg Lakes <br />DMG I/Z Permit <br />Page 7 <br />
