Map 3.02.2 M1, Bond Release Status Map has been revised and shows the new 276 acre disturbance area for PSCM and is included in this PAP response package. The area northwest of culvert 31A is included from the previous Seneca II mine facilities that are to be incorporated into the proposed PSCM facilities. Map 2.05.3 M1B, Mine Facilities Map (North End), has been revised to label this area as Equipment Lay down and Storage Area and to remove references to the waste rock disposal area. This revised map is also included in the PAP revision package. A related map, Map 2.05.4 M1, Sage Creek Postmining Topography has been revised to remove postmine topography that was associated with the waste rock disposal area and to show the revised PSCM disturbance boundary. This map is also included in this PAP response package. 62.
