<br />(a) Thickness of Reapplied Topsoil. Th <br />approximately one feet to upwazds of 2.5 <br />recommended by the NRCS. <br /> <br />e thickness of reapplied topsoil will range from <br />feet with an average depth of at least 1.7 feet as <br />(b) Seedbed Preparation. Following the reapplication of topsoil onto the regraded overburden sites <br />these areas will be ripped with either a dozer with a ripper bar, a motor grader or a tractor with a <br />chisel plow to eliminate compaction. The depth of ripping will be consistent with the depth of <br />reapplied topsoil to ensure that the quality of topsoil is not diluted by mixing with less desirable <br />subsurface soil materials. Following the completion ofthe seedbed preparation operations, the sites <br />will be seeded as described below. <br />Seeding will be performed depending on when the ripping and topsoil reapplication operations are <br />completed. Either fall or early spring seeding periods will be utilized. If the seedbed preparation is <br />completed during the summer or fall, then seeding will begin in the fall after fall frosts arrive. If the <br />seedbed preparation is completed during the winter or early spring then spring seedings evil] be <br />completed when the soil is dry enough to work, yet still somewhat moist. <br />Soil amendments such as supplemental fertilizers will be applied only if soil tests reveal a deficiency <br />for the identified plant nutrients for the plants to be seeded. In the event that tests indicate a nutrient <br />deficiency, then supplemental fertilizers will be applied at the levels recommended by the Colorado <br />State University Soils Testing Laboratory. <br />fc.) Species and Rates of Plants to be Seeded. The basic seed mixture will follow the <br />recommendations contained in the Soils and Vegetation Inventory which follows the <br />recommendations ofthe USDA-NRCS which they have recommended for numerous other gravel <br />pit reclamation projects in this area. <br />(d) Seeding Method. Preference will be directed towards drill seeding of all sites which are <br />artificially seeded at this location. In the event that drill seeding cannot be completed then the site <br />will be broadcast seeded at the rates specified in the USDA-NRCS recommendations and which are <br />contained in the soils and vegetation report.. <br />(e Mulching Due to the high amount of organic matter found in these topsoils and absence of slope <br />which would contribute to erosion, [here is no need for mulch to be applied to the topsoil stockpiles <br />at this site. At the time of final reclamation all of the revegetated aeeas will be mulched with either <br />clean straw or native hay mulch at the rate of one ton per acre. <br />(f) Shrub and Tree Plantings. Since the site is presently devoid oftrees, the reclamation plan will not <br />consist of the planting any shrubs or trees on any reseeded sites. Willows, Narrowleaf Cottonwoods <br />and other wetlands species will become readily established via natural establishment along the <br />perimeter of the proposed pond area as are evidenced by the abundance of these materials in the <br />abandoned gravel pits in the southeastern portion of the mine pit area. <br />13 <br />
