<br />Hydromulch: <br />Hydromulch may also be used. Additional seed species can be added such as Four- wing <br />saltbush and winterfat can be added to the mix up to '/~ pound per acre or sown <br />separately. <br />(e) There are a total of 3 phases proposed for the Russell Gravel Mine. It is estimated <br />that each phase will take approximately 10 years until all of the gravel material is <br />extracted for each phase. Each phase is 10 acres in size as shown on the Mining Map <br />(Exhibit D). The phasing sequence is identified by directional arrows also shown on the <br />Mining Map. <br />(~ <br />(i) The final gradient for all reclaimed slopes is proposed to be a maximum of 3;1. <br />(ii) Seeding types are listed above in Item D. <br />(iii) It is not anticipated that fertilization will be required for this site. <br />(iv) Re-vegetation will be consistent with the type of short-grass prairie that exists <br />in the surrounding area. <br />Comment: <br />(9) The applicant states that soil amendments shall be applied where soil tests <br />indicate nutrient deficiencies for the plant species to be established. Please <br />further explain the soil testing that will be conducted on site. <br />Answer: <br />A minimum of 5 soil samples shall be taken to determine if soil amendments and <br />additives will be required before seeding commences in the reclamation areas. The soil <br />samples shall be taken at a (6") depth and (3") diameter core. It is recommended that the <br />soil samples be taken to the Colorado State University Soil, Water & Plant Testing <br />Laboratory.
