5. The applicant has stated on page 18 that by the time mining is complete approximately 85% of the total <br />mined land will be reclaimed and that as mining ends in any given azea only final grading and shaping of <br />the slopes and recoiling will be needed. The applicant also states on page 6 that the bond is calculated <br />based on disturbing the entire azea, ie: 38.65 acres. In conformance with Rule 6.4.4(d), please clarify the <br />maximum disturbance to be expected at any one time that will be used in the determination of an adequate <br />reclamation cost. Such deternnation should include the following items: <br /># lineaz feet of working face at a height of 50-60' <br /># lineaz feet of unfinished slope, & at what configuration <br /># acres to be topsoiled <br /># acres to be revegetated <br /># acre-feet of finish grading <br />Also, the Division will assume the working face will be at a vertical configuration unless the applicant <br />wishes to commit to a working face at a configuration no steeper than a 1:1 slope at any one time. Please <br />respond. <br />6.4.5 EXHIBIT E -Reclamation Plan <br />6. In conformance with Rule 6.4.5(2)(d), the applicant has provided a grass seed mix composed of three <br />(3) species to be used during final reclamation. The Division suggests revising the seed mix to include 2-3 <br />additional grasses such as Indian ricegrass, arizona fescue, green needlegrass, or muttongrass to help <br />achieve apost-mining land use of rangeland. An example of a revised seed mix is listed below. Please <br />respond. <br />Species % of Mix Seed Rate <br />Smooth Brome 30 3.5 <br />Pubescent Wheatgrass 15 3.0 <br />Slender Wheatgrass 15 1.5 <br />Indian Ricegrass 20 2.0 <br />Arizona Fescue 20 0.5 <br />TOTAL ................. .....100 10.5 (lbs/Acre PLS) <br />* Double application rate for broadcast seeding <br />7. The applicant specifies on page 15 that there are limited wetland azeas associated with a spring on the <br />southwestern part of the site. Please clarify the following: 1) Will the limits of the wetland azea be <br />identified and mazked prior to mining disturbance? 2) if so, how will the limits be marked? 3) What will <br />be the elevation of the floor of the pit in relation to the elevation of the wetland during mining and during <br />reclamation? 4) What is the orientation of the natural drainage of the affected land and surrounding area <br />that may help to support the wetland? <br />6.4.12 EXHIBIT L -Reclamation Costs <br />8. On page 6 the applicant specifies that astorage/maintenance building will be constn;ctcd for use during <br />the mining operation, then removed when mining is complete.
