Damage to the 8 -inch fresh -water line into the mine required immediate repair. A backhoe was used to find the <br />• leak so that repairs could be undertaken. The pits dug by the backhoe were backfilled and the site(s) graded smooth <br />and seeded with the approved mixture. Seeding took place in the spring. <br />A new hole was drilled approximately 100 feet to the east of the existing one. This required preparation of a drill - <br />site, which included stripping topsoil from the drill -pad (approximately 100 x 100 feet) and stockpiling it adjacent <br />to the pad. Also, mud pits were excavated to handle the drilling fluids required for drilling the hole. To the extent <br />possible, the hole was drilled with air or air -foam, with very limited use of drilling mud or revert, to complete the <br />hole. Upon completion of this project the site was reclaimed, including backfilling the mud pit(s), grading the pad, <br />redistributing the topsoil, and seeding the site. The seeding took place in the fall. <br />In order to get the drill -rig to the site, the berm on the east end of the stoker pad was temporarily breached and the <br />rig driven over the ground to the railroad tracks. This is noted as a ramp on Map 24. The ramp was back dragged <br />after the rig exited the site, and the berm was reestablished. The new hole will be grouted, as per the approved plan, <br />upon abandonment of the system. <br />A trench was excavated from the Waste -Rock Pond to Location 3, and a 4 -inch waterline connected and buried to allow <br />an alternative point of supply for the water system. A trench, shown on Map 24, was excavated to allow connection of <br />the new fresh water supply borehole to the existing water supply line, and to connect the two boreholes. The topsoil <br />was set aside, the overburden removed, and the tie in line laid in the trench. The trench was then backfilled, the topsoil <br />replaced and the site seeded. In order to allow for long term access to the borehole a 72 -inch culvert was placed around <br />the well head. Upon abandonment of the system the hole will be grouted and the culvert pulled. The void remaining <br />from the culvert will be backfilled by the overburden that had been pushed up around it. The site will be seeded in the <br />fall, or first available growing season. <br />Another portion of the system, as shown on Map 24, is utilized to supply water to the mine. A pump, 30 -inch diameter <br />• borehole, and pumphouse were placed at the Site 114 spring, and a water -line buried from the pump over to the million - <br />gallon tank and borehole. The line was buried to an approximate depth of 7 feet. In order to facilitate the installation of <br />this line, topsoil was bladed to the side to provide an acceptable work area. The current temporary access road was <br />upgraded with gravel to allow year -round access to the pumphouse, with the topsoil being windrowed to the side of the <br />pad. The original borehole culvert was backfilled with washed rock within 1 -foot of the existing overflow point leading <br />to the Site 114 flume. This will provide a reserve diversion point should problems develop with the 30 -inch borehole. <br />A powerline will be installed from the corner of Colorado Yampa Coal Company's equipment parking lot to the pump <br />located at the spring. This will require the installation of 3 -4 power poles between the parking lot and the pump. A <br />mobile rig will be utilized to install the poles. Alternatively, TCC may tie into an existing buried power supply line and <br />extend it some 150 feet to the proposed pumphouse. A minimal amount of digging will be necessary to allow testing of <br />the existing line and burial of any extension in the previously disturbed area. During the interim period, a diesel - <br />powered generator will be used to run the pump. The generator will be set on the road leading to the PM bay, and a <br />cable will run from it to the pump. As soon as the powerline is installed, the generator will be taken out of service. <br />When the mine first experienced a water shortage, equipment was brought into the spring area to deepen the spring and <br />remove the flume from the spring's outlet. This resulted in a minor amount of disturbance to the reclaimed site when <br />the snow was pushed out of the way. When ground conditions allowed, the disturbed area was smoothed and reseeded <br />as necessary. Likewise, the material excavated from the spring was stabilized or placed back into the excavated hole. <br />If the spring is to be utilized for more than six months a fence will be constructed around the spring to keep animals out. <br />If the road to the site is continues to be used while the ground is soft, the topsoil will be bladed to the side and stabilized <br />with the temporary seed mix. Upon abandonment of this system the topsoil would be redistributed over the site and <br />seeded with the approved seed mixture. <br />• TCC also proposes to temporarily divert the portal mine discharge from Site 109 to Site 114 in order to augment the <br />emergency water supply to the million- gallon tank. This will involve routing Site 109 flows upslope toward the <br />operation center by means of a 6 -inch diameter line lying on the surface. Water discharged from this pipe will then <br />MR09 -238 2.05 -52 06/26/09 <br />
