3.0 Specific Reclamation Activities and Results 3.1 Phase I Areas As shown on Exhibit 1, each area requested for bond release is comprised of smaller units, which correspond to the specific year that backfilling and grading was performed. The work completed includes regrading to the approved post- mining topography and installation of post- mining drainage channels in required areas. Grading and topsoil replacement is generally performed in the summer and fall months. See Table 1- Summary of Reclamation Activities for an overview of the worked performed for each reclaimed area. The reclaimed areas have been regraded consistent with the approved post- mining topography (See Map 19 and 19A, Permit C -81 -019 for the approved post- mining topography) and follow all criteria set forth for Phase I bond release by the Division. Please refer to Exhibit 2A and 2B for five (5) representative cross - sections of the regraded areas in relation to the approved post- mining topography. The cross - sections indicate that the Phase I areas fall within the Division's guidelines of a maximum variance of 1 /2 of a contour from the approved post- mining topography and are well within acceptable mining practice. Permanent and temporary channels have been established in the Phase I areas, in accordance with the approved construction design parameters located in Permit C- 81 -019. These constructed channels including locations and cross - section are identified in the 2012 Annual Reclamation Report on file at the Colowyo Mine site and the Colorado Division of Reclamation Mining and Safety Denver office.
