<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.
