Trapper Mining Inc., T -123 Page 2 <br /> proposed in PR-9. The originally analyzed area of 139.3 acres assumed 2018 stripping previously <br /> submitted under PR-9 and subsequent TR-119. Impacts from future stripping areas would be <br /> lessened by the impact of opening N-Pit and its capture of local runoff. A similar condition will <br /> occur w ith the currently proposed stripping shortly after the topsoil is removed and 1 -Pit is <br /> opened. In either case the ponds demonstrated more than adequate capacity and freeboard when <br /> analyzed at 139 acres and should be adequate for the possible 2019 stripping total of 160 acres <br /> proposed in this revision. Total stripping for the new orientation of N-Pit is not anticipated to b <br /> much more than the proposed 160 acres for the fife of the pit. <br /> Drainage and culvert requirements of the proposed haul road will be addressed with the <br /> forthcoming update to the PR-9 application and will be designed in accordance with permit <br /> section 4.8.1.2. Immediate construction of the haul road is not expected at this time, but topsoil <br /> stripping may occur within the corridor as proposed. <br /> Current bonding for the site should be adequate as the proposed stripping in this technical <br /> revision is nearly identical in acreage to the N-Pit stripping proposed in T --119. None of the <br /> 201 N-Pit proposed stripping in TR-119 was completed, therefore no additional liability will b <br /> required for this technical revision. <br /> The anticipated relocation of the L.O.M. haul road in the vicinity of the proposed N Pit this year <br /> will increase the existing haul goad disturbance by approximately 5,800 feet. However, this <br /> increase in haul goad disturbance is offset by recent reclamation of 5,766 feet of Middle Z haul <br /> road. <br /> If you have any questions or comments,please contact Sao. <br /> Sincerely, <br /> Graham Roberts <br /> Environmental Engineer <br /> Robin Re ill y-two copies w/attacliments <br /> Jennifer Maido,BLM w/attachment <br /> File 109.2.3.4 w/o at#aeliments <br /> Revisions File <br />
