3) Inaccuracies in the scrapper and truck load counts. <br />4) The scrappers did not remove the complete 18" as instructed. <br />5) Due to the irregular shape and area involved in the permanent removal <br />area, the planimetering of this area may be inaccurate. <br />A combination of each explanation above may be the reason for being short <br />of topsoil at the present time. However, over the life of the mine there wil be <br />sufficient quantities of topsoil available for replacement of 18 inches of seedbed <br />material on all acreages disturbed. A review of the soil survey of the waste rock <br />embankment on the upper bench shows that 286000 yd3 of topsoil are available for <br />removal from the 50 acres that will be effected. All of the available topsoil will <br />be removed to provide a properly engineered foundation for the waste rock <br />embankment. Replacement of 18 inches of seedbed material on the 38 acres of the <br />waste rock embankment would leave 194000 yd3 of seedbed material for <br />replacement on other mine site areas. This is depicted by an east-west cross- <br />section of the waste rock embankment area soil depths shown on Figure 1. Figure 1 <br />also indicates the amount of topsoil needed for waste rock reclamation and how <br />much topsoil is available for use elsewhere on the mine site. Consequently the <br />present information indicates that there is sufficient topsoil on the site to replace <br />18 inches of seedbed material on all presently anticipated disturbed areas at the <br />end of mining operations. <br />5 <br />
