The purpose of <br />the request is to develop a reclamation plan to be implemented after mining is completed. <br />The pit site is located in a portion of section 1 which is east of Nyberg Road and North of the <br />Arkansas River, in T21S, R63W, 6`h PM. The following information may be used to fulfill <br />reclamation requirements. <br />The owner of the land is Kenneth L. Koslowski. The operator, Trans Colorado Concrete, <br />will be responsible for reclamation. The post-mining land use will be wildlife habitat. <br />Attached is a list of soils found on this site. The primary soil for gravel extraction will be <br />Bloom silt loam. The soils Ap, Lm, LnA are not prime farmland soils, These soils are more <br />fully described in the attached material including a description of the soil mapping unit. <br />Copies are included of the tables from our soil survey database: Chemical Properties and <br />Physical Properties, and Construction Materials. Please note that these properties are <br />typical of the native, undisturbed soil. <br />The Natural Resources Conservation Service recommends the following steps to revegetate <br />the site: <br />1.) Topsoil should be removed and stockpiled. When mining is completed, the topsoil <br />should be placed so that at least six inches of topsoil material is <br />covering the subsoil material. Topsoil amounts exceeding six inches in depth will <br />result in increased seeding success. <br />If the topsoil will not be used within one year, then it should be seeded with <br />the seed mixture listed in step #5 to protect it from erosion and keep it <br />biologically active. <br />2.) Prior to revegetation, the area should be banksloped so that no slope exceeds a 3:1 <br />slope. Slopes greater than 3:1 will need to have some type <br />of erosion control blanket applied after seeding to reduce erosion and increase <br />seeding success. Roads and other similarly disturbed areas should be graded or <br />reworked so as to blend into or approximate the surrounding landscape as closely as <br />possible. Rough areas should be smoothed to permit easier seeding and mulching. <br />At least eighteen inches of subsoil material should remain on-site prior to spreading <br />the topsoil. The subsoil material should not be over-compacted. Plant roots will not <br />be able to grow in heavily compacted subsoils. Also, compaction reduces the <br />amount of water available to the plant. Additional soil material, topsoil or subsoil, <br />will increase the success of the seeding. When banksloping and shaping of the <br />subsoil is complete, scarify the area to a depth of six inches to permit better bonding <br />The Natural Resource Conservation Servitt wort hand-in-hand with <br />the American people t0 conserve natural resources on private lands.
