inch polyetlrvlene LP line will be buried from the tank ro [he new bathhouse and will include a vaporizer located <br />• some ~0 feet from the tank. <br />The Fish Creek Borehole Area will be used for discharging mine water. Facilities to be constructed at the Fish <br />Creek Borehole Area are shown on the following maps: Map 26, Fish Creek Borehole Area Facilities and Access <br />Road; Map 27, Fislt Creek Borehole Area Access Road Profile; Map 28, Fisli Creek Borehole Area Access Road <br />Profile and Typical Cross Sections; and Map 32, Fislt Creek Borehole Settling Pond Plan view and Cross <br />Sections. The mine water discharge boreholes will be required in 1989. Total disturbed area required for the <br />above facilities would be less than 10 acres. Access to the sites would be as shown on Map 29, Reclamation. <br />Standard maintenance procedure such as preventive maintenance programs, painting, and lubrication shall be <br />utilized throughout the life ofall the structures. All facilities will be removed and the area reclaimed to its original <br />use at the completion of mining activity except to the extent alternative postmining land uses are approved. <br />EASTERN MINING D1STR[CT <br />Mining in the Eastern Mining District will require the installation of a new dewatering facility and three fans. One <br />of the fans will be installed in entry 0, and approximately 600-800 fee[ in by the portal mouth. The location of this <br />fan places i[ within the current surface facilities area, therefore, no new disturbance will be associated with the <br />installation of this fan. The approximate location of the fan is on the bench between [he stoker coal storage area <br />and the materials storage area. This fan will be of similar size and capacity as the existing main mine fan. The <br />location of the fan is shown on Map 23. The installation of [his fan was approved in MR94-107 <br />Two additional fens will he installed in 1996 or 1997. The location of the fans are shown nn Maps 17A, 18A, and <br />• 23. The fans will be constructed at [he end of panel 9 Right, and will be used to augment the main mine fans. The <br />installation of the fans will require the construction of an access road into the site, establishment of a construction <br />site, establishment of a topsoil stockpile, running a powerline to the site, and inscribing a diversion ditch upslope <br />of the construction site. Approximately 2 acres will be disturbed by the upgrading and extension of dte road and <br />construction of the fan site. <br />A new dewatering facility will be constructed at the location shown on Maps 17A, ISA, and 23. The facility will <br />he located above the lowest point in the Eastern Mining District. It is anticipated the facility will be constructed in <br />either 1995 or 1996. The facility will be comprised of an access road, dewatering well, water line leading to <br />settling ponds, hvo settling ponds, aeration channel, control building, powerline, and discharge point. the flow <br />from the pond will be pumped from the pond to Foidel Creek in a buried line. A discharge permit application will <br />be filed with the Colorado Department of Health to allow discharging from this facility. This facility will be <br />similar to the Fish Creek dewatering borehole system except that only one dewatering +vell will be constructed. <br />Approximately 3.4 acres will be disturbed during the construction of this facility and it associated access road. <br />Mine Water Return Line <br />A water line will be installed from the EMD dewatering facility roFCM-2 to route water back into the mine for <br />underground operations. The location of this water line is shown on Figure 16 1, 1996 Seismic Lines and Mine <br />Water Discharge Return Line, East Mine District. Approximately 7,300 feet of 8-inch HDPE pipe will be buried <br />at 5 to 6 feet below grade from the dewatering facility to FCM-2. This pipe will he left in place when no longer <br />required. <br />. Trenching operations will be conducted using a trackhoe with a working area assumed at 40' in width. <br />Approxnnately 7 acres will be disturbed in the construction of the water line. The trench will pass through hvo <br />major soil types: Binco silq~ clay loam and Coche[opa loam. Approximately 4,200 feet of the water line will pass <br />through the Binco group with a topsoil depth of 30 inches and 3,100 feet will pass through [he Cochetopa group <br />MR 97-I ~4 2.05-5~ Revised 9/9/97 <br />
