Seedbed Preparation The site will be harrowed prior to seeding. This procedure should form a smooth, firm seedbed that will facilitate seeding. Seeding will be done between 12.5 and 25 Ibs per acre. If after 1-2 growing seasons,it becomes obvious that the planting was unsuccessful,the site will be reseeded. Fertilization The site will be fertilized prior to seeding. Fertilization will be implemented following Soil Conservation Service guide�ines. Forty pounds of actual nitrogen and forty pound of actual phosphate per acre will be applied. This should be approximately 125 Ibs per acre of commercial fertilizer. Lon�Term Mine Plan and Reclamation If this plan is successful,then the next step will be to expand to the next block upstream to the edge of the property and expand the permit. Once that has been mined and reclaimed then a new stream channel will be built in the reclaimed ground and the current stream be moved into it.Then to finish the block,the old ditch channel and adjacent piles will be mined and reclaimed. The very last step in this will be to trench across the bottom of the block and place a groundwater impediment out of either compaction or a synthetic liner that will pool the groundwater up in the reclaimed ground just under the reclaimed block to restore the riparian environment. The only surface water exposed will be the stream channel. This will have to be done in the late fall at a point of the least amount of water in the system. The next year another block will chosen and the process is mined and reclaimed until all 50 acres are reclaimed.All of this will depend on grade, groundwater, gravel porosity, and clay content. Storm Water Plan At the upper end of the pond, (farthest from the existing drainage)the pond will be connected to the old wash panels for a discharge and percolation. They will not incur more disturbance, but will act as a surge feature during storm events.This witl allow extra precipitation to escape the pond and infiltrate into the groundwater system through the gravel piles in 72 hours.. The operation will use no chemicals and will only segregate minor amounts of silt and clay long enough to settle it out in the gravel and in the pond. The ultimate goal will be to assure there is no connection to surface water of any sediment or turbidity. Should any be observed,the operation will shut down immediately to correct the problem. There will be no impounded water so no danger of dam failure exists. Ground water will flow as it always has a#this stage. It will only be collected briefly in the pond which will act like a sump with the water flowing through the subsurface.
