NEWMONT GOLDCORP. 1 RECLAMATION AND CLOSURE The objectives, criteria and procedures of the reclamation and closure plan for the Cresson Project have been previously approved through Amendment 9, Amendment 10, and Amendment 11 review processes. Procedures proposed as part of Amendment 13 build upon those previously approved practices, as discussed below. 1.1 Objectives The objectives of the reclamation and closure plan are to stabilize disturbed areas and re- establish the pre -mining land uses of wildlife habitat and livestock grazing (rangeland). These objectives will be achieved through the implementation of the reclamation and closure practices described in this section, and the appropriate use of other technologies that may become available. Upon completion of reclamation and closure, the majority of affected lands will be returned to rangeland and wildlife habitat. Historic resources will be preserved to the extent practicable and made accessible to the public, where feasible and safe. Interpretative guidance (i.e., informational signs) on both the historic and recent operations will be developed, where feasible. 1.2 Summary of Amendment 13 Impacts to Reclamation There are no significant changes to the overall reclamation plan proposed under this Amendment 13. Amendment 13 incorporates minor changes to the interim and final grading plans for the Schist Island mine area and the Squaw Gulch Overburden Storage Area (SGOSA). 1.3 Growth Medium Materials The availability of growth medium has been updated to reflect current availability. Drawing C -4b shows location and size of growth medium storage areas. Soil types were mapped based on existing data available from the NRCS, as confirmed by field reviews (Arcadis 2015). The results of this mapping are summarized in Exhibit I and the report, titled Baseline Technical Report for Soils and Biological Resources (Arcadis 2011 and 2015) is included in Appendix 5. The reclamation and closure plan incorporates roughly six inches of growth medium replacement on overburden storage areas (OSAs), select haul roads into the surface mines, certain surface mine backfills, the Arequa Gulch Valley Leach Facility (VLF1, herein called VLF1) and re- contoured Squaw Gulch Valley Leach Facility (VLF2, herein called VLF2), support facility sites, reclaimed portal area, and other ancillary disturbance areas to be reclaimed. To accomplish this reclamation, approximately 2.4 million cubic yards of growth medium will be required. It is Cripple Creek & Victor Gold Mining Company Exhibit E Cresson Project Amendment 13 1
