retention. The reclaimed road bed will be seeded with the approved seed mix and <br />mulched with clean straw at an application rate of no less than 2000#/acre. <br />22. The seeding rate listed by NRCS planner James Sperry will be used for <br />revegetation of the site. The NRCS rate is listed as 5.9 PLS/ac in the last column <br />of the Range and Pasture Seed. Rate will be doubled if seed mix is broadcast. <br />Exhibit F-Reclamtion Plan Map <br />23. The Reclamation Plan Map will be checked and corrected to show no final slopes <br />greater than 3:1. <br />24. Post Mining Use of Rangeland will be added to the Reclamation Plan Map. <br />Exhibit G-Water information <br />25. The intent of the mine operator is to reduce the size and water storage capacity of <br />the sediment control berm below that which is necessary to require obtaining a <br />temporary water supply plan or permit for water storage while maintaining <br />effective control of stormwater flows from the site. Water will percolate into the <br />soils in the shallow basin behind the berm within 72 hours after a storm event, or <br />the mine operator will improve percolation characteristics of the materials used <br />in/under the berm to guarantee that storm water is not impounded for any longer <br />than allowed by Colorado Division of Water Resources regulation. If it remains <br />the determination of the Division that a water storage plan or appropriate permit is <br />required, the operator commits to do so. <br />26. Water used for dust control will be acquired from the mine operator's <br />industrial/commercial water supply located 2 miles NW of the mine site. <br />Exhibit L-Reclamation Costs <br />27. The operator agrees that a phased approach to bonding is best. Phase One work <br />will take a minimum of 15years to complete or longer, depending on extraction <br />rate. <br />28. The $600 grading cost estimate is based on time estimated for a large dozer to <br />push and compact a one acre area from muckpile to adjacent mining face at one <br />foot intervals of push and compaction. This estimate assumes that the rock has <br />been drilled and blasted and is left (after blasting) within thirty feet of the mining <br />face from which it was blasted. Mine faces of up to 200 feet in length may be <br />reclaimed at any one time. Cost estimate to drill and blast rock that will be used <br />for backfilling the mining face is $1 per cubic yard. Using up to a 30 foot face, <br />200 feet of mine bench will take 10000 cu yard of rock backfill and grade to 3:1. <br />29. If overburden is found of sufficient volume to cover bedrock prior to topsoil, <br />Seifert commits to applying a minimum of 6" of overburden. Cost estimate for
