rxlllarr "n" S ~ <br />ARNING PhAPI <br />The Mining Plan b Timetable Pfap (Exhibit C) portrays the sequence of <br />extraction as projected on estimated demand. The timeframe could vary <br />depending on the business climate, but the sequential design appears to <br />be the best met}rod of extraction. lstimated life of this deposit is <br />20 years. <br />Test borings of the permit area indicate a topsoil depth of 9" to 15" <br />with an additional 1' to 5' of overburden on the L'op of t-lre aggregate <br />body. The aggr.egaL'e body proper ranges from 13' to 24' in depth with a <br />projected 20' average depth. Topsoil will be excavated first arrcl stoclcpilecl <br />on the north, west and south perimeters for replacement in reclamation. <br />• Then overburden will be stripped, segregated from the topsoil and stock- <br />piled separately, also on Lire nortlrcoest and south pit perimeters. It <br />appears that' there call be an excess of overburden for backslopiug the <br />pond perimeters. Tlris excess overburden will be used to add sinuosity <br />to the shoreline and reduce the total amount of pond surface area, as <br />well as to construct a 2' high flood contral bean on t-he south perimeter <br />as well as a portion of the west perimeter. Topsail stockpiles, if left <br />in place for more than 1 growing season, will be seeded with an SCS <br />recommended vegetation cover to preserve their integrity. <br />At this time, 4 methods of extraction are going considered: <br />1. Dragline <br />2. Sauerman <br />3. Dewater. & excavated c~itlr front-end loader. <br />4. llredge <br />If dewatering is the selected method, Lire operator does already have <br />ilPDES Permit tlo. COG 500032. <br />1Jo matter wlricir method of extraction is chosen, extraction will begin at the <br />PIIJ corner and proceed to the SI.1 corner in the first pass, with subsequent <br />passes being excavated in the same manner and proceeding easterly with <br />each pass. Extracted mlterial will be transported by truck, field conveyor, <br />or front-end loader to a portable crushing, washing and screening plant wlriclr <br />will be located in the northease quadrant of Lire Section 34 portion of the <br />• permit area. Material will be processed and stockpiled for transport by truck <br />to the required locations. <br />As the extraction passes proceed east, backslopi.ng in the excavated area <br />will follow extraction as closely as consistent with operational constraints. <br />Top soiling and reseeding will follow backsloping caith 6 to 9 months. <br />The operator plans to operate this project nn a 20-acre floading bond. <br />Disturbance areas are projected as follows. <br />a, llajor - stripping, and excavation - 12 acres <br />b. Pfoderate - balcslopinp, and topsoil replacement - 4 acres <br />c. 1~tinor - final grading and reseeding - 4 acres <br />
