Parkdale P~ect ~ 4 • Reclamation Permit 2.0 Post-mining Reclamation Activities Described below are the general specifications and methods to be employed following conclusion of mining activities at the Parkdale Project site. 2.1 Grading Concurrent reclamation of disturbed aeeas will be implemented to the extent possible. Where possible, overburden will be directly placed eliminating creation of stockpiles and double handling. Mined areas will be backfilled with available overburden waste and graded. Current grading plans include development of apost-mining topography graded to 3:1 or flatter that is self-draining which blends into adjacent undisturbed lands. At closure, the quarry azea will have access to benches blocked with large boulders. Pit faces and benches will be left in as mined topography with the floor to be neazly level so as to be free draining. The proposed post-mining bench configuration includes 50 toot bench heights with no less than 50 foot depth for an overall slope angle of 45 degrees or less. The post-mining configeration of the highwall feature (200 feet total height) is well within reasonable and conservative engineering limits for a long term safety from the standpoint of overall slope stability. 2.2 Ripping Compacted Surfaces Road, work, stockpile areas and other compacted surfaces will be ripped to a depth of 12 inches along the contour prior to the placement of topsoil. 2.3 Soil and Overburden Replacement Depths Overburden will be placed to create apost-mining topography that is self-draining and which blends into adjacent undisturbed lands. While soil depth ranges between 6 and 18 inches over the area to be mined, in some areas it is less than 6 inches and therefore is not available for salvage (see Exhibit I). Salvaged topsoil will be supplemented with the addition of screened fines from aggregate processing operations. All reapplied topsoil will be placed as evenly as possible. The replacement depth for mined aeeas, facility level areas and the quarry floors will be greater than 6 inches but less than 10 inches. No topsoil will be placed on quarry benches or faces. 2.4 Ferti-izer (Seedbed Material) Sampling General Procedures: The laboratory selected to analyze the samples will be contacted at least 15 days in advance of [he sampling period [o aid in coordinating sample analysis with the beginning of revegetation activities on site. All samples will be taken with either a ale spade or soil auger. This equipment will be free of all foreign substances and rust. No galvanized tools will be used. Approximately 1 quaff of material will be collected for each composite sample.
