Essentially, the sites which are most severely burned aze also the highest on the slope and <br />little area remains above them to erode down. The other sites sit in well-protected <br />timbered areas not significantly affected by the Ere. <br />As earlier stated, any potential sheet erosion coming from off Hayman burn sites will in <br />fact be trapped by any excavations located downslope. Any reclaimed sites will likewise <br />absorb any sheet erosion because the new disturbances are far more permeable than the <br />burned sites. <br />Gully erosion should not be a factor as dig sites do not significantly enter drainages and <br />we will continue to avoid doing so. <br />Rule 6.3.3 Exhibit C-Mining Plan <br />Soils: Please provide an estimated depth to which soil, suitable as a plant growth <br />medium, will be salvaged for use in the reclamation process. This description must be <br />consistent with information provided in Exhibit B. Sufficient soil must be salvaged to <br />meet the vegetation establishment criteria of Rule 3.1.10. Please note that topsoil and <br />overburden should be segregated <br />Sorry, I did not clearly state my meaning. "Generally about 8 inches of soil and subsoil <br />will be stockpiled ... " Specifically, I will strip the soil from the surface down to a depth <br />of 8 inches. This soil, including at times, some subsoil because the topsoil in areas is not <br />8 inches deep, is stockpiled. <br />I will not likely strip soil from excavated areas because the soil has already been <br />removed. If it appears there is some reestablishment of soil in very old digs, then, I will <br />strip and store that soil as well, because it is much better than none. <br />The stockpiled soil, which includes subsoils, will be used in the reclamation process. <br />Based on the areas where soil is absent, the average depth of returned soil and subsoil <br />should be 5 to 6 inches. To date, this has been shown from previous experience to be <br />sufficient for reclamation and for establishing good growth of reclaimed areas. <br />Overburden: Clarification on the application statement that no overburden will be <br />removed It should indicate that overburden will be removed from the ground to access <br />the cavity bearing pegmatite, but no overburden will be removed from on-site. <br />Let me clarify my statement, "There is no overburden to be removed." <br />Unlike deposits, such as coal beds, wherein uneconomical rock (overburden) is in place <br />above the coal deposit and must be removed to expose the coal, the pegmatite deposits <br />can occur from the surface down and valuable crystal cavities and loose crystals can be <br />found from the surface down. No overburden is removed. Similar to a gravel pit, it is <br />segregated into different components. The entire deposit (less the topsoil) is mined. <br />
