SEDIMENT CONTROL <br /> The sediment control system will be broken down into three separate <br /> areas: <br /> AREA 1. TUNNEL TO TRANSFER (See typical cross-section) <br /> This area will be almost entirely reclaimed after construction: i.e. , <br /> both cut and fill slopes. The remaining area will include an access <br /> road which will be re-seeded. Use of this road is estimated to be once <br /> a week to inspect the belt. Each end of the belt (200' to 3001) is <br /> inside a sediment pond area. Special scrapers will be used to ensure <br /> that the belt will run clean. It is requested, that the actual belt <br /> line, 6 to 8' wide x 3000' long, or 0.55 acres , be given a small area <br /> exemption. The access road adjacent to the be.'_t line would be water- <br /> barred to existing topography or every 1001 , whichever applies. The <br /> clean water (borrow ditch) would have a culvert-- evi.-ry 500 feet and/or <br /> at natural drainages. <br /> AREA 2. TRANSFER POINT <br /> This area includes the main belt transfer to the No. 1 stockpile and <br /> the No. 2 stockpile (see map) . This area covers approximately 5.65 <br /> acres and would be added to Area 7 bus garage sediment pond system for <br /> a total of 7.58 acres. The No. 2 pond (-008) -„ould be enlarged 0.90 <br /> acre feet to accommodate the extra area. (See attached Pond drawings <br /> and calculations.) (Current NPDES Discharge N(: ,, CO-0000396-008.) <br /> AREA 3. NO. 1 MINE STOCKPILE AREA <br /> This area would be designated as �the No. 8 Sediment Pond System and <br /> would cover the cut and all portions of the new No. , Mine stockpile. <br /> The pond would be sized for the total disturbed area (8.61 acres) even <br /> though a large portion (50 to 60 percent) will be revegetated following <br /> construction. This pond will contain 1.38 acre feet of storage. (See <br /> attached pond drawings and calculations. <br /> An additional NPDES discharge permit (020) has been applied for. The <br /> discharge will be into Coal Creek above the wash plant. <br /> il <br />
