A portion of this exemption is a seeded topsoil stockpile. All <br />water drains to the south and is filtered through a silt fence <br />located west of the extension. The area below the silt fence is <br />vegetated and serves as a vegetative filter. <br />- Warehouse/shop area - covers 5.88 acres and is located on a <br />north facing slope below the shops. Water drains through <br />established vegetation, gathers along the railroad track embankment <br />and runs along ditch F-2 toward the culvert under the light-use <br />road adjacent to Pond F. The water impounds before the culvert <br />before flowing through the culvert. Once through the culvert it <br />will flow down the north side of Pond F and the light-use <br />road/railroad embankment. The area is vegetated and serves as a <br />vegetative filter to inhibit flow. There will also be a rock check <br />dam which will additionally filter surface runoff prior to exiting <br />the site. <br />- This fifth small area exemption involves 8.3 acres of <br />reclamation at Mine 2. The area was seeded in 1982 and the north, <br />east, and south sides are bordered by bond released reclamation. <br />Runoff from the area is minimal due to the high percentage of <br />vegetative cover. <br />- Tipple $2 Loadout Tunnel which consists of small disturbed <br />area surrounding the tunnel on the east side as identified on <br />Permit Renewal Map 5 (Roads, Powerlines and Facilities). The <br />surrounding area is well vegetated and rock/gravel filter dams have <br />been installed in the ditches along the railroad track. This small <br />area exemption was approved by the CMLRD on June 23, 1988 with MR- <br />88-27. <br />- Stoker Coal Loadout which covers 1.8 acres and is located <br />north of the Old Equipment Parking Lot and adjacent to the railroad <br />tracks. Sediment control in the area consists of a berm and rock <br />filter located on the west side of the bench, and a rock filter on <br />the north side of the railroad track. This will control any <br />potential surface runoff from the bench area. <br />- Topsoil Stockpile 3-3 is located to the southwest of Pond K. <br />Sediment control is accomplished by existing vegetative cover, a <br />sump, and a stock water pond. <br />- Pond B access Pad comprises some 0.3 acres adjacent to Pond B. <br />The area is gently sloping, with heavy vegetative cover on adjacent <br />areas bordering Foidel Creek, acting as a filter to prevent <br />sediment contribution to the stream. CYCC will also construct a <br />berm and rock filter to further control and treat any runoff which <br />may be generated. <br />- Pond D east area cover 0.7 acres adjacent to the emergency <br />spillway and the haulroad. Runoff from this area flows along the <br />haulroad, and collects between the haulroad and the Pond D <br />Page 5 <br />
