Included are <br />revised Maps M9 and M10H as submitted earlier under Permit Revision No. 1 <br />CPR-1). Map M9 shows the proposed haul/walk road and access roads to be built <br />related to our 1987 road system. Please note that there are two alternatives <br />for a short section of the haul/walk road. Final cut and fill volume calcula- <br />tions and haulage distances will dictate the route to be used. Please consult <br />Map M10H to see how the haul and access road system ties in with the 1987 <br />mining activities. <br />This road system was originally planned for construction beginning in 1988. <br />Map M9 of Permit Revision No. 2 (PR-2) shows the forecast route planned for <br />the 1988-1992 permit term. As can be seen, the route has been moved north a <br />considerable distance but will tie into Ashmore Pit at approximately the same <br />location. Trapper needs to begin work on this road system this year to allow <br />for construction of access coads to Ashmore Pit. They are necessary to permit <br />servicing the north end of Ashmore Pit as it moves east. Construction must <br />begin this year to meet operational access needs. In essense, Trapper is <br />requesting to begin work on this road system a year earlier than planned. <br />Topsoil will be stripped and stockpiled prior to road construction. Map M10H <br />shows the approximate topsoil stockpile locations. Note that runoff from the <br />area affected by stockpiles and most of the roads will be controlled by <br />Trapper's sediment control system. A small portion of the haul road will <br />cross West Pyeatt where no downstream sediment control currently exists. <br />During the construction phase of the haulroad in the West Pyeatt area, various <br />temporary erosion control practices will be used to reduce sediment dis- <br />charges. These will include but are not restricted to straw bale dikes and <br />the use of erosion cloth. Seeding of roadsides will follow this fall. Seed <br />mix to be utilized will be as shown in Table 3.6-10 of Trapper's mining and <br />reclamation permit. <br />cont. <br />P.O. Box 187 Craig, Colorado 81626 (303) 824-4401 <br />
