Mr, Chris Rowe <br />December 12, 2006 <br />Page Six of Eight <br />4. There are no long-term maintenance requirements associated with <br />compacted pit liners. Over the past 30 plus years, compacted liners have <br />proven to be functional, durable, and maintenance free. <br />6.3.5 EXHIBIT E -MAP <br />Excavation (Mininel Plan Map <br />1, Please see attached Excavation Plan Map. <br />2, Please see attached Excavation Plan Map. <br />3. Because the Idaho Creek Resources sand and gravel pit has a Substitute Water <br />Supply Plan approved by the SEO it can be assumed that there is a well permit for <br />their pit, which is located within 600 feet of the proposed Camenish Borrow Site. <br />Lining the Camenish Borrow pit will have no impact on the Idaho Creek <br />Resources well. The Idaho Creek Resources well is the pit, which has been <br />de-watered for several years and will remain so until all mining and <br />reclamation work is completed. If anything, the de-watered Idaho Creek Pit <br />has lowered the ground water level under the proposed Camenish Borrow <br />Site. Because excavation and reclamation will be concurrent at Camenish the <br />compacted pit liner will completed before de-watering ends at Idaho Creek. <br />Once Camenish has been lined it will be effectively cut off from the <br />surrounding alluvium and any impacts to the hydrology of Idaho Creek <br />Resources will end; although it is difficult to see how dewatering Camenish in <br />the first place could in any way adversely impact the hydrology of an actively <br />de-watered Idaho Creek Resources Pit. <br />Finally, Gke the Camenish Borrow Pit, the Idaho Creek Resources Pit will be <br />lined in order to seal it from the surrounding alluvium. In the end, there will <br />be two bathtubs, neither capable of effecting the water Level in the other. <br />4. Please see attached Excavation Plan Map, <br />5. As shown on the revised Excavation Plan drawing (Sheet 1 of 2), the gas well <br />is the property of Kerr McGee. The pipeline from the well is buried under <br />the strip of land between the well and the north permit boundary (see <br />attached Excavation Plan drawing). <br />Reclamation Plan Map <br />1. There is no drainage conveyance structures associated with the stock pond. <br />2. All reclaimed slopes shown on the Reclamation Plan Map aze at a 3:1 slope. <br />
