Below are items to address the technical review of 28 May 2003 affecting Glacier Peak Mining, Permit <br />Application M-2003-030. <br />15. 6.3.4 Eh') 3IBIT D - RLCLAMATTON PLAN <br />6.3.4 (I) (a) Overburden replacement <br />Revise estimate of reclaimed area upwards to include reclamation of previously disturbed area4. <br />Reclamation will reclaim approximately 1/5 of an acre (9,000 sq') of disturbed area each season. This <br />includes the footprint for equipment being used, areas where topsoil was stored, prospects, previously <br />disturbed azeas surrounding excavation sites, and the actual excavation. Actual excavations are about <br />3,000 sq' per year. <br />Planned equipment for reclamation will primarily ronsist of the same equipment used during the actual <br />excavation. The majority of work will be accomplished with amedium-size excavator such as a 370 C <br />john Deere. Its design allows it to bring overburden, including rock, back up lull easily without a great <br />deal of moving the equipment around. Atrack-loader with blade such as a 555 Jolut Dccre will be <br />used to do final contouring and smoothing of the excavation and surrounding disturbed areas. The <br />excavator will then be bA~ought back in to redistribute topsoil from the storage pile over the re- <br />contoured surface. The loader will then be used to redistribute the topsoil and rake the azea. At this <br />time, it will be reseeded and re-raked with the Ioader blade. We will hand rake as necessary to cover <br />seed. <br />If necessary we will re-grade an area ur use a spike scrocn to prepare the soil for reseeditag if the soil <br />has become compacted. We can drag a spike screen with the same back hoe, such as a Case SIC 580 or <br />an ATV or, if necessary, hand rake the area. <br />The loader will be brought on site only during the actual reclamation, usually a single day. Otherwise, <br />other equipment on site will be the excavator or a back hoe which will be on site during the entire <br />excavation. <br />Our original proposal indicated a time line through 2018 with final reclamation completed on Qui-Buc <br />No, 2 that year. Total disturbance over the 15 years was projected to be slightly under 3 acres. This <br />included equipment footprints, storage areas, some reclamation of curtrtrtly disturbed areas, and <br />prospecting. On average, we would disturb or reclaim previously disturbed areas at a rate of 1!5 of an <br />acre per year. Alter the first ycnq each site is reclaimed until at the end of 2018, we would have <br />reclaimed and reseeded our .final pazcel, As a result of removing Qui-Buc No. 2 this would reduce the <br />total dish,rhed area by 2/5 of an acre. Total disturbed and reclaimed azeas for this permit would now <br />be 2.6 acres, I would leave it at 3 acres. I would plan on reclaiming additional disturbed areas near <br />our proposed excavation sites, particulazly on the Smoky Hawk where most of 3 acres is currently <br />disturbed. <br />Dascd on this, bond estimation should he for 1/5 of an acre during any one year. <br />
