The tailings in the retention pond and tailings that <br /> formed its embankments were excavated and hauled to the Mayflower <br /> Mill - Tailings Pond #4. In addition, tailings material spread <br /> over the alluvial fan area were removed and hauled to the Tailings <br /> Pond #4 facility. The total material excavated and hauled to <br /> Tailings Pond #4 was 5700 cubic yards. This amount exceeded the <br /> 1300 cubic yards estimated due to the cleanup of the alluvial fan <br /> and because the pond berms were thought to be soil whereas they <br /> were tailings capped with a layer of soil. <br /> After excavation and grading, the work area was neutralized with <br /> limestone and hydrated lime sprayed with a hydromulcher. The <br /> quantities used were 10 tons of limestone and 700 pounds of <br /> hydrated lime spread over the 2 .5 acre site. After neutralization, <br /> exposed tailings in the Hwy. 110 road-fill were capped with 1 - 2 <br /> feet of subsoil. Small areas across the site were also capped and <br /> holes created by excavation were filled with the subsoil material . <br /> Pre-tailings ground contours were left as final grade. This <br /> included leaving the old railroad grade as undisturbed as possible. <br />
