Adequacy Letter Reply continued <br />The hydrologic balance will remain undisturbed. On-site and off-site drainage <br />patterns, and flow amounts will remain essentially the same as before ruining <br />commenced. New drainage patterns will not be established and the affected land <br />areas created by mining will have the same runoff potential (once grass is <br />established) aspre-mining runoff. <br />No clay is processed on site. It is mined and stockpiled. Haulage from the <br />stockpile is by truck and on a demand basis at the plant in Castle rock. <br />The soil type is identified as Lithic Entosol by the Thorne report. A copy of that <br />Repor[ originally submitted with the Dawson Mine application and permit is <br />Included with this report. <br />3. Exhibit E. -The type of reclamation is to restore the mined azea to rangeland. All <br />of the surrounding land is rangeland and the owner, The State Land Boazd of <br />Colorado has previously stated that they want the land restored to rangeland use. <br />Reclamation will be implemented by backfilling and grading each phase area as <br />mining is completed. As each phase is completed by mining, reclamation will be <br />initiated by backfilling and grading immediately while the mining equipment is <br />still on site. Seeding and tree planting will be done as soon as the season permits <br />and in no instance longer than one yeaz from the completion of backfilling and <br />grading. <br />The entire disturbed azea will be backfilled (ff needed) and graded so as to blend <br />into the existing topography and be appropriate for rangeland use. More acreage <br />for rangeland will result from the mining and reclamation as the knobs or hills <br />that are not suitable for grazing will be flattened making their slopes more <br />acceptable for grass growth. <br />Backfilling will only be in localized azeas necessary to keep the reclaimed area in <br />a flat profile. The backfilled material will be compacted using scrapers and a <br />dozer. <br />Topsoil will be stockpiled in a flat azea and will be covered with plastic and the <br />plastic staked. This method will protect the topsoil stockpile from wind and water <br />erosion. <br />TopsoIl replacement on graded slopes is not anticipated, however the topsoil will <br />be seeded immediately after placement by drilling and mulch distributed as <br />recommended by the Soils Commission. <br />
