information is required by DMG to adequately review this Amendment application, it can be provided separately and confidentially per DMG Rules and Reguations. Phase I (complete mining in the Central Quarry and expanded mining in the North Quarry) will be completely developed in approximately 5.6 years at presently projected production rates. Important considerations for this phase are to develop the Central Quarry into a reservoir, develop upper portions of the North Quarry, and improve North Quarry visual appearance while expanding [he area available for process facilities. Phase I development is illustrated in Figure D-1. Phase [I (complete mining in the North Quarry and initial mining in the South Quarry) will follow Phase I mining. It is estimated that Phase II will take approximately 10.3 years to complete. Important considerations for this phase are to develop the North Quarry into a potential reservoir site while minimizing visual impacts and disturbance. Phase II also allows initial mining in the South Quarry. Phase II development is illustrated in Figure D-2. Phase III (mining the new, upper portions of the South Quarry) will follow Phase D mining. Phase III will take approximately 14.8 years to complete. Important considerations for this phase are to develop the South Quany while minimizing visual impacts and disturbance with concurrent reclamation of upper, visible areas. During Phase III, runoff from Unnamed Drainage No. 1 will be diverted [o Unnamed Drainage No. 2 to allow further quarry development while maintaining surface drainage. This diversion will be accomplished by developing the upper one or two benches to full length along the western quarry wall followed by channeling or piping flows from Drainage No. 1 along the bench to the south. A spillway structure or pipe with appropriate energy dissipation and sedimentation controls will be used to direct flows down the natural slope past the termination of the benches. Prior to bench development and diversion along the benches, the present drainage patterns will be maintained. Drainage design details will be developed within the recommended conceptual design consistent with the drainage study which was presented in Amendment No. 4 and which is not repeated herein. Phase IV (complete mining within the South Quarry) will follow Phase III mining. Phase IV will take approximately 16.5 years to complete, assuming continuance of recent production rates. The important considerations for this phase are [o extract [he remaining rock reserves with concurrent reclamation to minimize exposed ground at any given time. The area disturbed in Phase IV is at or below El. 6,640 ft which is generally below the top of [he ridge of rock remaining to the east and, therefore, will no[ be generally visible to viewers below and to the east and southeast. Note that the maximum buildout configurations shown for each phase are contingent upon encountering competent enough rock [o sustain the slopes as shown. Ongoing geotechnical evaluations will determine [he actual final buildout which may necessarily be less aggressive than shown on [he figures. For all mining rxT [V-S
