Permit Amendment (AM-06) - Climax Mine 0 • • identification in the field. The proposed affected land boundary includes a reconfigured delineation of lands in the areas of the Mayflower TSF and McNulty OSF that were initially included within the affected land boundary approved in 1977 and AM-01. These areas were removed from the affected land boundary in AM-02 to facilitate a financial warranty reduction during a period of low molybdenum prices. While not precisely identical, the extent of proposed affected lands associated with these facilities is comparable to that previously approved. Figure AM-06-C-01 (Exhibit C) presents a site map identifying the 1980 (AM-01) affected land boundary, the 1997 boundary, and the current proposed affected land boundary. The proposed affected land boundary also includes an area immediately downstream of the existing Mayflower TSF. This area is included to provide for a contemplated Property Discharge Water Treatment Plant (PDWTP). CMC plans to construct a new water treatment plant at this location to facilitate continued protection of the environment and ongoing compliance with regulatory requirements. Therefore, this area meets the CMLRA §34-32-103(1.5) affected land definition of "the surface of an area within the state that is or will be disturbed by the operation...". The detailed design for this plant has not yet been completed. Climax plans to submit the detailed design information for approval in a future technical revision to the permit. The proposed adjustment to the affected land boundary is an administrative change to the existing permit, which will facilitate implementation of previously approved mineral extraction activities and ongoing protection of the environment. Therefore, it does not represent a significant change in planned mining operations or an expansion of facilities. 1.4 Organization of Permit Amendment Application This application is organized in relation to permit amendment application requirements of HRMMR §§1.10(1) and Rule 6.4.
