well with a pump station. The wet well will accept incoming flows that will fill the <br />reservoir. The incoming flow will enter the top of the wet well and exit through an <br />inlet/outlet pipe that is placed at the bottom of the wet well and extends out into the <br />reservoir on the bottom of the reservoir floor. The inlet/outlet pipe on the bottom of the <br />wet well will also function as an equalizer pipe to allow water into the wet well so when <br />the discharge pump station is operated water can be pumped/removed and discharged <br />to the end users system for use as augmentation water or perhaps raw water that could <br />be treated and used for potable water. <br />Reclamation Measures/Materials Handling <br />Backfilling will be done to provide stabilized shorelines around the reservoir and to <br />minimize erosion. The backfill material will consist of native bedrock claystone, gravel, <br />overburden, and topsoil. There will not be known toxic or hazardous materials in the <br />backfill material. Additionally, it is not likely that acid forming or toxic materials will be <br />encountered during mining. The mining will not leave high walls on the property. In <br />addition, there will be no auger holes, excavations, or shafts left on the property. <br />Overburden and topsoil that is removed during the mining will be used to reclaim the <br />mining slopes and areas that are disturbed during the mining such as haul/access roads <br />and the recharge pond. Overburden will be placed in the areas such as haul/roads and <br />the recharge pond to bring the grade to the final reclaimed elevation. The overburden <br />may also be spread on the 3H:1V mining slope to use the excess overburden to <br />exhaustion. This will be accomplished by using a dozer to spread the overburden <br />material to a depth of one foot or less across the entire mining slope thus maintaining a <br />3H:1 V slope. The slope will be compacted as described in the previous paragraphs for <br />the Water Storage Reservoir. Topsoil will then be placed to finalize the grading such <br />that seeding can occur. The topsoil will be placed at all disturbed areas and on the <br />mining slope to an elevation matching the expected reservoir water level. <br />Top soiling <br />The top six inches of soil on the property is classified as topsoil. This layer includes the <br />root zone of grasses and crops, which will be stripped and stockpiled separately. By <br />using concurrent reclamation techniques, the topsoil is not expected to remain in <br />stockpiles for more than one to five years. If the stockpile remains more than one <br />growing season, it will be seeded with a fast growing vegetative cover to prevent <br />erosion. All topsoil will be retained on-site to reclaim the reservoir shoreline, and other <br />areas disturbed by mining activities. Where required, topsoil will be replaced to a depth <br />of approximately twelve inches. <br />Revegetation <br />As mining operations are completed, areas for reclamation will be graded and shaped <br />for revegetation. Runoff or excess water from adjacent areas will not be allowed to flow <br />over slopes being graded and seeded. If needed, berms or channels will be constructed <br />to divert excess water and dispose of it in a safe and non-erosive manner. t Project <br />I DRMDeff <br />S 112 Permit <br />I J&T Consulting, Inc. <br />W
