TRAPPER MINING INC. <br />III IIIIIIIIIIIII III <br />CERTIFIED #P175046684 <br />Mr. Kent Gorham <br />July 8, 1992 <br />JUG 131992 <br />215oCenteMm; B d nd Reclamation Division \v\S\QN U~ U~~~ <br />g• D ~ ~,~0~ <br />1313 Sherman St. M1NE~Al.S <br />Denver, CO 80203 <br />Dear Kent: <br />RE: MR-119 Topsoil Exclusion Areas For Hawken Pit - 1992. <br />Enclosed is an updated M56 "Areas Excluded From Topsoil Stripping" map showing the additional <br />acreage Trapper proposes for exclusion of topsoil salvage while developing H pit in 1992. Trapper pro- <br />poses to exclude several small boulder fields or rock outcrops and a larger rock bluff approximately 6.5 <br />acres in size immediately adjacent to the previously approved exclusion area north of A pit (ash disposal <br />area). The total area affected is approximately 8.5 acres. This area is very steep, has very shallow soils <br />and is dominated by large igneous boulders. Efforts to salvage topsoil in this area would create unsafe <br />conditions for scraper operators and would likely damage equipment. Permit page 4-250 discusses <br />Trapper's approved procedures for excluding topsoil salvage when necessary. <br />Excluding this area from topsoil salvage does not create a future shortage of [opsoil when replacement <br />efforts wmmence in Hawken pit. Trapper estimates 487,000 bank cubic yards will be salvaged from the <br />166-acre Hawken pit mining area. The topsoil quantity needed to replace this disturbance, at our <br />approved 12-inch depth, is 267,800 bank cubic yards. The resul[ing balance is an approximate 219,200 <br />bey topsoil surplus. <br />Kent, if you have any questions or concerns, please wntact me or Bill Harding. <br />Sincerely, ////~' <br />~~/~rl!~~2`- <br />William Agnew <br />Mgr.
