<br />M-97-071 <br />Page 7 <br />especially concentrate on the post-mining effects. Also, has the local Division of Wildlife <br />Office been contacted to help in preparing the wildlife statement? The Division will be <br />interested to hear their opinions on the potential impacts to wildlife in the area as this may affect <br />the design of the reclamation plan. <br />6.4.9 EXHIBIT 1- Soils Information <br />The soil descriptions supplied with the application are adequate to describe the soils present on <br />the proposed mining site along with the proposed reapplication depths. <br />6.4.10 EXHIBIT J- Vegetation information <br />(1) The application should include a narrative of the following; <br />(a) descriptions of present vegetative types which include quantitative estimates of <br />cover and height for the principal species in each life form represented( ie, trees <br />tall shrubs, low shrubs ,grasses , fortis etc.); <br />(c) estimates of carrying capacity for rangelands; <br />(2) The application shall show the relation of the types of vegetation to existing topography <br />on a map in Exhibit C. <br />6.4.11 EXHIBIT K-Climate <br />No Comment. <br />6.4.12 EXHIBIT L- Reclamation Costs <br />There are a few questions and clarifications required for this exhibit as follows: <br />I .Although it appears that calculations were conducted for replacing one foot of topsoil over I S <br />acres, the summary of tasks in the middle of page 34 shows a soil depth of 6 inches. <br />2. The average push distance for respreading the topsoil that was used was 250 or less, however, <br />on a 15 acre disturbance the lengths of the pit walls would be approximately 800 feet. <br />Depending on the pit configuration and where the topsoil is stockpiled, 2~0 feet seems to be <br />short on the push distance and consequently on the cost per cubic yard to move. <br />3. The application states that the deposit is up to 20 feet thick, therefore, the Division would <br />assume that the slope reduction height would be 20 feet not 10 feet over a distance of <br />
