Dudash R~(`~(VE~ <br />Environmental Protection Specialist Jul 1 4 1336 <br />Colorado Division of Minerals and Geology <br />1313 Sherman St., Room 215 DIVISI()R <br />Denver, CO 80203 Ot 1"~oefdl~ & Guuiogy <br />Dear Joe, <br />Subj: Trapper Mioe, Permit No. C-81-010, Minor Revision MR-]47 <br />Topsoil Haulage Route to Topsoil Stockpile D-77-1. <br />To complete topsoil replacement activities in Derringer Pit this year, Trapper will need to utilize topsoil stockpile <br />D-77-1 (see Appendix W, 1995 Annual Report). Haulage routes will be established across areas previously <br />replaced with topsoil and seeded to perennial species. The enclosed Figure MR 147-1, shows the locations of the <br />haulage routes. Not all of the stockpile will be required for [he 1996 laydown area. Consequently, the remainder <br />of the stockpile will be moved to [he recontoured spoils and stockpiled for future use. Approximate locations of the <br />new stockpiles are shown in Section 5.0 of Trapper's 1995 Annual Report. This move will allow reclamation of <br />the stockpile and road areas while placing the material closer for use in reclamation in Derringer Pit. <br />Topsoil will be removed from the routes and placed adjacent to the area. The routes will be approximately 80 feet <br />wide and total 8375 feet in length. The stockpile will be depleted this summer and the roads reclaimed shortly <br />after work is complete. Seeding will follow this fall. <br />The first portion of the road leading from the D-77-1 stockpile falls within a narrow corridor of Trapper's Permit <br />Boundary. No sediment control structures are in place to prevent runoff reaching outside the permit boundary <br />from the resulting road work. Therefore, silt control sWCtures made of straw bales or small berms will be con- <br />structed to "treat" runoff prior to leaving the area. This combination of structures will be used to direct runoff to <br />points where straw bale filters will block sediment discharge. <br />Total disturbance for [he roads to move the stockpile is approximately 15.4 acres. Bond estimates [o replace topsoil <br />and seed this small azea are included within the Bonding package being submitted under Trapper's mid-term <br />review. This cos[ is included within [he costs requested by the Division concerning previous minor revisions. <br />]oe, please contact me if you have any questions concerning this request. We would like to begin later this month <br />on preparing the access road so work can be accomplished in a timely manner <br />Sincerely, I <br />~r(~%7~~:~Y <br />Forrest V.
