M. D. Hester -2- Mar h 8, 1984 Maas The Exhibit C map of the C-JD-B mine (portal site) is of ode uate scale to illustrate the disturbance here. It would be helpful to llustrate the area of the production shaft, etc., located on top of th mesa, in a similar manner. 2. Similar to the comment given in number 1 immediately above, a would encourage the inclusion of a reclamation map for the product on shaft site of suitable scale to help better portray the post-minln topography of this site. 3. Access roads are considered part of the affected lands. Thel maps should clearly illustrate the location of all access roads to be used in conjunction with this operation (those roads other than public roads). The application should then discuss the manner in which you will minimize excess downslope spoiling on the steeper portions f any cut and fill slopes. And, provide a plan of reclamation for al such accesses. Reclamation Plan 1. Information given regarding understory vegetation shows tha galleta accounts for approximately 20% of the total cover. However, this species is not given in the proposed seed mixture, and we suggest that it be incorporated. Also, because of the aggressive nature of yellow sweetclov~r, we suggest that you cut the proposed rate by 75% to 0.5 lb/ac. 2. we strongly recommend the inclusion of mulch (suggest 2 to~s/acre hay, crimped) to help promote revegetation efforts. 3. Grazing should be prohibited until vegetation has an opportunity to establish. 4. There should be a plan to appropriately secure adits and shafts (Rule 6.1{e)). 5. Considering the fact that erosion is accelerated on steep slopes and the long-term adherence of topsoil is thus questionable, the pplication should discuss the erosion control practices which will b implemented to improve stability (e g, rough grading, contour furrows etc.). 6. The application mentions a plan to combine fine fractions from the waste rock dump with topsoil to increase the volume of availabl plant growth medium. The Division requests some additional information regarding the expected nature of the waste. Such information may Include: expe ted volumes of fines, expected size fractions, chemical and radiogenic ature of the waste, and any other information regarding the sultab111 y of this material.
