Mud Creek Pit -Reclamation Permit Application -112 (C) Exhibits Page 10 of 67 <br />SECTION D-3. MINED, UNM/NED, AND DISTURBED AREAS: <br />A total of approximately 100.9 acres (including 3.6 acres already mined by prior owners) will be mined, or 65% of the <br />total site/permit area. <br />Three areas, totaling 53.5 acres, will not be mined, as shown on Map C-3: <br />1. An area of 17.7 acres adjacent to US-160 will not be mined and will form a visual, noise, and dust barrier <br />for the operation. Approximately 0.64 acres of this area will be disturbed for construction of 934 feet of 24- <br />foot wide permanent road. <br />2. The northwest comer of the site, 27.4 acres, including the slope down to the Mud Creek Valley and a <br />portion of the valley floor, will not be mined; Approximately 3.39 acres will be disturbed for an access road <br />and permanent plant site (Plant Site B). <br />3. An area in the northeast corner of the site, 7.9 acres of forested slope, a small natural swale which carries <br />irrigation return flows, and immediately adjacent to a series of stock ponds off-site, will not be mined. <br />Approximately 0.19 acres of this area will be disturbed for a temporary access road. <br />Therefore, of the 53.5 acres of the 154.4-acre site NOT mined, a total of 4.22 acres will be disturbed, of which 0.19 is <br />temporary and 4.03 is permanent. <br />SECTION D-4. STRIPPING AND MINING TECHNIQUE: <br />STRIPPING: Stripping for access road construction will be done and the topsoil temporarily windrowed then used to <br />reclaim the borrow ditches on the road. Excess material will be sold and shipped from the site: there may be small <br />(2,000 CY or less) temporary stockpiles associated with road construction for Years 0-2, located in the south buffer <br />zone or in Plant Site A. Otherwise, as discussed above, all stripped topsoil will be placed in berms along one edge of <br />the area being mined (generally on the Southeast edge of the area to be mined) to assist in controlling dust, visual <br />clutter, and noise. The stripping will be done on a yearly basis. There will be no discharge of storm water from a <br />stripped area (except for bar ditches for the access road) without first flowing through a sediment basin and other <br />storm water controls; most storm water will infiltrate into the ground rather than discharge on the surface: the goal will <br />be zero discharge from disturbed and un-reclaimed areas, in accordance with the Surface Water Management Plan <br />(SWMP). <br />MINING: Mining will be conducted in a single cut averaging 20 feet in depth. Exact depth will vary to ensure proper <br />drainage, convenient reclamation to an acceptable slope, and to allow for storm water control during and after mining. <br />No dewatering is anticipated. <br />Mining consists of: <br />1. Stripping and conserving topsoil (1-3 feet, averaging 2 feet). These materials will usually be moved to stockpiles <br />immediately adjacent to the area being mined; <br />2. Removing of the sand and gravel (15-30 feet, averaging 20 feet) with loaders and/or backhoes, <br />3. Moving these excavated materials by loader or truck to stockpiles for the screening and crushing (processing) <br />plant; normally the plant will be in the area being mined, or in the area most recently mined and immediately <br />adjacent to the area being mined; <br />4. Screening ,crushing, and/or washing of sand and gravel (using portable plants), moving these to stockpiles in <br />the plant area prior to shipping from the site or for use by on-site concrete or asphalt plants; and <br />5. Placement of excess materials (clean construction debris, fines and oversize) by loader for backfilling, generally <br />as soon as possible and as material is made available. <br />McStone Aggregates, LLC 15 FEB 2008 ©WASTELINE, INC 2008 PN 5006.1-4(009) <br />
