I . ,' • • <br />tv-:i <br />Resoiling the haul road, Borrow Source 1, and backfilled highwatl disturbances to a nominal depth of <br />~:~ <br />6 inches or more forms the basis of Alternative Two. Resoiling these areas with suitable soil materials <br />F: <br />r.':' having elevated WHC values would increase the potential for reclamation success substantially. However, <br />this could require a significant financial commitment and would delay the onset of revegetation activities <br />c" from 6 months to one year depending upon the planting season chosen if a source of soil were found in <br />"' the interim. A delay in revegetation activities would also require that EFMC control erosion on these <br />r graded areas until planting and mulching are completed. <br />3.) Locate a source, if one exists, of soil materials for future use at the project site if revegetation of graded <br />>~j overburden areas is to be attempted. This source would serve as a back-up if the reclamation of such <br />f.. <br />areas was deemed unsuccessful. If at all possible, this source should be from other construction sites <br />within the region where surplus soil materials are being generated and are unwanted. Disturbing <br />~~'~ additional areas near the mine site for the sole purpose of generating soil materials for recoiling purposes <br />should be considered a last resort given that this increase in disturbed acreage would require bonding <br />and would add to the area EFMC would be required to reclaim. Sampling and laboratory analysis of any <br />identified soil source would likely be required to determine overall suitability for use. <br />` 4.) Any gravel roadbed material overlying the haul road (as represented by sample point RC-5), either at <br />f i the surface or immediate subsurface level, should be removed and properly disposed of if a disposal area <br />!~ ~i <br />p~~~y can be located within the region. <br />f:; <br />• 5.) Deep rip all areas to be revegetated prior to seedbed preparation excepting those on which soil <br />G <br />materials have been respread. <br />~~;} 6.) Disk all areas to be seeded, along the contour, as a means of seedbed preparation to reduced <br />compaction. <br />~! 7.) If available and chemically suitable, organic materials can be added to graded areas having overburden <br />I as the seedbed material. However, it must be remembered that such a technique will not affect the WHC <br />~~ of the seedbed to any depth deeper than that of organic material incorporation. <br />~ 8.) Obtain fertilizer recommendations from the Cooperative Extension Service at Colorado State <br />~,a <br />University (303-491-5061) based on the results of laboratory analysis included in Appendix 2 of this <br />,,l report. <br />~s. <br />9.) Consider drill seeding techniques in lieu of broadcasting. Drill seeding will place seeds directly into the <br />seedbed which may be considered an advantage on a surface dominated by a sandy clay material subject <br />to compaction. Drag chains should be used in place of packer-wheels if drilling is chosen. Contact the <br />r•.i __~~ 15 <br />
