..:,. • TR9PPE8 INI~INA INC. August 1, 1989 CERTIFIED ttP175046595 Mr. Tony Waldron Colorado Mined Land Reclamation Division 215 Centennial Bldg. 1313 Sherman St. Denver, CO 80203 Dear Tony: • iii iininiuiiiiii 999 ~~g'~ NUC ~ 1y~g ~ECLA!14AY O1V DIDVIS1p;~l Subject: Minor Revision MR-89 Haul road corridor for Browning/Colt Pit Map M-9 of our current mining and reclamation permit illustrates the haul road construction schedule and routes for Trapper Mine. As currently permitted and as we discussed on 7/18/89, this map does not show the haul road corridor through our 1992 removal limit in the B/C pit mining area. The same scenario existed for the D pit ramp 3 extension (approved MR-86) in that it was assumed haul road construction was approved through our current permit term with the approval of PR-2. Construction of this haulroad in 1989 is necessary to accommodate mining in the B/C pit area. Enclosed is a new M-9 (sheet 2 of 4) map that shows the route for the B/C pit road. By overlaying the new M-9 map over M10A map, you will see that the road extension is in an area that will be stripped of topsoil during this permit term. The area is already included in the bond calculations so no change in the bond amount is needed. Additionally, adequate sediment control is in place in East and West Buzzard drainage. As shown in Appendix Q, Section I and II, the sediment control facilities present in the drainage were built based on a worst-case distur- bance. Therefore, no changes in the sediment control plan for East or West Buzzard drainage is required. Topsoil will be stripped and stockpiled prior to road construction. The final stockpile is shown in Trapper's 1988 (Submitted 3/89) annual report. Seeding of the stockpile will occur in the fall. The seed mix to be used is as approved in Trapper's 1988 annual report.
