Topsoil found within the planned facilities area was removed for <br />• redistribution upon the graded area. Exhibit 23 contains the Bear <br />No. 3 Mine topsoil plan. Map 1 in Exhibit 23 shows the following <br />four classifications of areas to be revegetated: <br />Classification Acres <br />1. Area To Be Re-Topsoiled 5.2 <br />2. Topsoil Stockpile 0.3 <br />3. Area Not Topsoiled, But Will 2.3 <br />Be Scarified and Seeded <br />4. Area to Be Left in Place 0.8 <br />at Reclamation <br />TOTAL AREA DISTURBED 8.4 <br />An estimated 3600 cubic yards of topsoil was originally salvaged. <br />During August 1993 the sediment pond at the Bear No. 3 Mine was <br />enlarged. Approximately 0.2 acres was disturbed. The topsoil <br />salvaged from this area was placed on the topsoil pile shown on the <br />Mine Facilities Map (Map 10). Approximately 430 cubic yards of <br />topsoil was salvaged which equates to an average depth of 15 <br />inches. Therefore, a total of 4030 cubic yards of topsoil is <br />available (3600 + 430). <br />To cover the 5.2 acres with 6-inches of topsoil, 4195 cubic yards <br />• are required. The 165 cubic yard shortfall of available topsoil is <br />not considered significant. <br />• 4.15-4 <br />Revised September 17, 1993 <br />I <br />
