'~ <br />daily. A maximum of 30,000 cu.yds. may be backfilled into the Orphan pit <br />during the next year. The backfill volume of the North Orphan put should <br />sustain the Newlin Creek operation throughout the five (5) year permit term. <br />The general operational plans for transporting and placing the material is <br />explicitly developed through a mutual agreement between Harrison-Peltron and <br />G.E.C. Minerals. Harrison-Peltron shall transport development waste from the <br />Newlin Creek mine site and deposit and grade the material into the abandoned <br />surface mines. G.E.C. Minerals will then cover, prepare the seedbed and <br />revegetate the area. <br />Backfilling volume in the surface mines is planned to be apportioned between <br />G.E.C. and Harrison-Peltron. Harrison-Peltron anticipates most of the <br />backfilling material will originate from the Newlin Creek mine. The volume of <br />the material shall be limited to the available capacity restricted by the <br />practical operational procedures and compatibility with environmental <br />standards approved by Colorado Mined Land Reclamation Board for this specific <br />project. <br />The general requirements for the backfilling of the Orphan pit-shall adhere to <br />(1) A maximum crown after 10$ conslidation would result in a slope not <br />exceeding 1v:lOh. (2) The crown shall be placed near the area of maximum pit <br />depth. (3) A maximum 10$ material compaction and; (4) A fill limit of four <br />(4)-foot minimum bench from the fill to the outer limit of the pit. The crown <br />shall be left far natural settlement of the material to approximate the <br />original premining slope and all material shall be placed and graded from the <br />existing access. <br />No constructed access or ancillary disturbances are presently anticipated to <br />be required during the backfilling of the Orphan pit or North Orphan pit. Any <br />additional construction or disturbance in which Harrison-Peltron is directly <br />responsible shall be removed and/or reclaimed by Harrison-Peltron. <br />The general requirements of rule 4.14 are outlined below: <br />4.14.1(1) Timing <br />The deposited material shall be regarded and placed by a small <br />dozer when an adequate amount of material is in place to <br />
