If needed, one or two mowing treatments per year may be utilized to help suppress other vegetation that may compete with grass establishment in the disturbed areas outside ofthe areas that are returned to cropland. v. The property will be monitored once a month from May through October,providing adequate time to implement the spraying program as described above. g) The reclaimed Koskie site is not anticipated to encounter groundwater or surface water and will have no ponds. The mining area access road may be left in place following cessation of mining. h) Reconnaissance of the Koskie site indicates that the thickness of overburden to be removed during gravel extraction is minimal. Therefore stockpiling of overburden piles is not anticipated. Soils and waste rock unsuitable for construction materials will be separated from the gravels and may be stockpiled at the site. These soil stockpiles will be utilized for excavation backfill and site reclamation. i) Reclamation, backfill, and seeding estimated costs: Under$60,000.
