Reclamation plans for the Robinson tailing surface , <br /> including the pool area, are currently to cover the tailing with <br /> waste rock from the open pit to a depth of three feet, followed by <br /> ripping in a straw or wood chip mulch with an initial fertilizer <br /> application. Most of the approximately 60 ,000 cubic yards of <br /> topsoil from the Kokomo Aggregate Area ( stored in the Mayflower. <br /> Topsoil Stockpiles) will be available during Phase III to create <br /> islands of soil over the rock to a depth of 6 to 12 inches. The <br /> Climax seed mixture will be hydroseeded last. The pool and water <br /> channel area of Robinson will additionally have sewage sludge <br /> spread over it, since this reclamation will occur. during Phase VI <br /> when there is no concern of organic compounds contaminating the <br /> industrial waters . Depending upon the outcome of our <br /> investigation into the use of sewage sludge, the material may be <br /> used over the total tailing area. <br /> Reclamation for flood control as described in Section 8 , <br /> WATER, will provide the means of properly draining the reclaimed <br /> tailing area. <br /> 10 . 22 OXIDE TAILING POND ( 18 , 19 ) <br /> Water of the Oxide Tailing Pond ( 18 and its dam ( 19 ) is <br /> currently being reclaimed by pumping and dilution with industrial <br /> water . Following dewatering operations , the area may be utilized <br /> as a tailing deposition backup system or as a surge reservoir for <br /> storing industrial water. . Reclamation on the 64 acres will not <br /> occur until Phase V following mine shutdown. Open Pit waste rock <br /> taken from waste disposal sites, or riprap rock, taken from <br /> sources near the pond , will be used to cover the tailing material <br /> to a depth of approximately three feet. A straw or wood chip <br /> mulch will be ripped into the material along with an initial <br /> fertilizer. . Sewage sludge , if available , -also will be ripped in <br /> and the surface seeded with the Climax seed mixture. An <br /> appropriate fertilizer scheme will be used if sewage sludge is not <br /> available. Spruce trees and selected 'nigh-altitude shrubs will be <br /> planted during the second year . <br /> 10-19 <br />
