SSA <br />such materials are acid or toxic producing, as will not significantly affect <br />the inert nature of such solids. The term includes, but is not limited to, <br />earth, sand, grave, rock, concrete which has been in a hardened state for at <br />least sixty days, masonry, asphalt paving fragments, and other inert <br />solids. <br />Christopher L. Varra, President <br />Varra Companies, Inc. <br />(d) The backfilling commenced on an initial level to provide for stockpiling <br />near the point of entry. Active backfilling will not extend beyond this point <br />except to provide for stockpiling at these entry points until this Notice has <br />been approved by DMG. Depending upon the rate at which material is <br />generated on-site or secured from off-site locations, the rate of fill is <br />expected to occur over a period of (10) years, or approximately three (3) <br />surface acres per year. <br />(e) The backfilled lake will create a level surface suitable for agricultural, or if <br />provided for by subsequent permit modification, a wetlands bank. <br />Finished fill will have a cap of overburden (including 6 inches of soil) a <br />minimum of two (2) feet in depth. <br />(f) Voids and settling will be avoided by placement of material into an <br />inundated medium. Fines generated from the wash plant are constantly <br />emptied into the pond at an approximate rate of 30,000 tons per year and <br />will settle into voids displacing the water until the existing basin is filled. <br />Per Part (10) and (11), all mined material to be disposed of within the affected <br />area will be handled in such a manner as to prevent any unauthorized <br />release of pollutants to the surface drainage system; and, no unauthorized <br />release of pollutants to groundwater shall occur from any materials <br />mined, handled or disposed of within the permit area. <br />- end - <br />DMG Backfill Notice for Varra Companies, Inc. - Dakolios Pit - Permit-M-84-036 2
