I 10.) Restoration Plan Restoration will be an ongoing process. As an area of mining is e completed, and mining advances to a subsequent phase, reclamation will begin on the completed phase. Reclamation activities at the site will consist of backfilling, grading, and seeding. Work will be ' concentrated on the sideslopes around the perimeter of the site. The base of the site may remain open to accommodate mining activities, various haul roads, stockpile areas, etc. Final grades will range from ' 1 % to 25%. Final restoration grades are shown on the Reclamation Plan, Sheet 3 of 3. ' Topsoil shall be placed on graded areas to be reclaimed. The area shall be seeded within 6 months of completing the backfilling. Topsoil will ' come from on-site sources, and be placed in a layer that is a minimum of 3" thick in accordance with the city ordinance. After placement of topsoil is complete, it shall be seeded and mulched according to Minnesota Department of Transportation (MnDOT) Standard Specification No 3876 and 3882. The seed used shall be MnDOT seed mixture 50A. The mulch shall be Type I. It should be recognized that portions of a given phase, for example, along borders of subsequent phases, within the processing and operations area and ' along haul roads, may be left at an intermediate stage of reclamation until completion is practical. 1 III STANDARDS 1 .) Boundary: Extraction operations shall be conducted within the confines of the ' boundaries indicated within this application. 2.) Setbacks: Site setbacks will be fifty feet from property lines and right-of-ways that are not adjacent to other areas where mining is allowed.
