<br /> The operator initiated removal of topsoil in the RDA. Topsoil salvaged to date has
<br /> been hauled to the topsoil pile west of the refuse belt(Map 11, Surface Facilities and
<br /> Roads-East Portal). (This topsoil pile was relocated to Topsoil Stockpile No 2 in 2012) During initial
<br /> topsoil stripping operations the operator had a problem of mixing topsoil with refuse
<br /> and as a result came up with the following plan for salvaging topsoil to satisfy the
<br /> Division.
<br /> 1. The operator was committed to salvaging as much "topsoil" as reasonably
<br /> possible without endangering men and equipment. Salvaging depths will vary from
<br /> zero to 60 inches depending upon slope and aspect. This will more than likely
<br /> include topsoil, subsoil and parent material.
<br /> 2. In order to improve workability of refuse,the operator will utilize parent material
<br /> (greater than 18 inch depth). The actual volume required will depend upon reject
<br /> fines, inherent refuse moisture and rainfall.
<br /> 3. The operator will construct salvage pads approximately 50 to 100 feet wide, 3 to 4
<br /> inches deep to provide a buffer between in-place refuse and newly stripped topsoil.
<br /> These pads will be constructed from parent material. Topsoil will be either pushed
<br /> downslope to the pad or recovered with a backhoe. If feasible topsoil will be loaded
<br /> directly into a haul truck and transported to the topsoil stockpile. If not,topsoil will
<br /> be loaded with a frontend loader for transport.
<br /> 4. The operator will at all times maintain a minimum vertical buffer zone of 20 feet
<br /> between in-place refuse and undisturbed topsoil.
<br /> As operations progress in the RDA more efficient methods may be developed to
<br /> handle topsoil in this area.
