Current slopes are in the <br /> range of 1 : 1 to 2 : 1 . <br /> - Pond surface will be graded at approximately a one percent <br /> slope toward the hillside. <br /> Stabilization of the side-slopes and top is accomplished by <br /> erection of four-foot snowfences perpendicular to prevailing <br /> winds and application of a non-toxic cementing agent to bind <br /> loose tailings material . <br /> Revegatation is accomplished by a process of spreading peat <br /> in hand dug furrows on 12" centers, fertilization, seeding, <br /> maintenance and establishment of secondary plant <br /> communities . <br /> No definite schedule for reclamation. <br />
