of the Interior has approved the proposed mining plan. Status of Stipulations and Revisions to the Permit Between 1988 and 2001,the Division submitted 13 stipulations related to the New Elk Mine. Review of the stipulation file in the Division's Permit System indicates that all stipulations have been complied with or otherwise terminated. There are no active stipulations at the time of approval of Permit Renewal Number 7 (RN-07). The Division has approved two bond releases related to the New Elk Mine: SL-01 and SL-02. In 1998, the Division approved Phase I, II, and III bond release of 3,233 acres south of Highway 12 (SL-01). This action released this area from further liability, as per Division written policy for release of areas overlying underground workings. Of the 3,233 acres included in SL-01, 597 acres had been undermined but not disturbed at the surface. Included in the 3,233 acres are two small areas of surface disturbance (the Apache Canyon ventilation shafts), which were transferred to the Golden Eagle Mine (Division permit C-1981-013). The Division approved a partial Phase 1 Bond Release (SL-02) in 2006 for 35.14 acres. SL-02 approved completion of demolition of structures, backfill, and grading of 19.08 acres at the East Portal, and 16.06 acres at the West Portal. SL-02 also released liability for activities that had previously received approval but had never been implemented, and these activities were removed from the approved permit application package (PAP). The three acres from the Golden Eagle Mine (see TR-72 description below) have received Phase I bond release.
