Those areas around the periphery of the pit will be graded for drainage where necessary and seeded using standard techniques. Peripheral roads not needed for access will be scarified and/or ripped and seeded. On some areas surrounding the pit, 4"-6" of topsoil may be applied prior to seeding. Rock Dumps Lack of available topsoil generally will preclude any great degree of revegetation success on the rock dump complexes noted in Appendix D (Map ID areas A3-A5) . Upon termination at the end of the mine life , these dumps will be contoured on top for drainage and stability. The dump tops and roads will be scari- fied or ripped and seeded. Where feasible, 4"-6" of topsoil will be applied to dump tops prior to seeding. The dump slopes will be seeded if the results of the seeding trials to be con- ducted over the next several years on No. 1 dam indicate that a viable degree of success in revegetation can be expected. The possibility of some success presently is evidenced by compari- sons with the rock faced dam slopes on Robinson Lake and No. 4 dam reservoir (Appendix D; Map ID areas F3 and F4 ) . Reclamation Monitoring To date, monitoring of reclamation programs at the mine has con- sisted primarily of regular visual examinations of both newly reclaimed areas and sites which have become self-sustaining over the years . In addition, selected research and trial plots have been reexamined periodically and the data reported in various reclamation symposiums and research papers (refer: Exhibit Q - Company Sponsored/Co-sponsored Research ) . These two monitoring methods have resulted in refinements in reclamation techniques and materials over the years as well as providing the basis for assessment of site-specific reclamation progress. These moni- toring methods have been successful in the past and thus , will be continued throughout the future of the Climax Mine. • E-9
