dragged after the rig exits [he site, and [he berm will be reestablished. It is anticipated [he drilling ++'ill be complete <br />• within 2-4 days. <br />The new hole would be grouted, as per the approved plan, upon abandonment of the system. <br />A trench will be excavated from [he wasterock pond to Location 3, and a 4 inch waterline connected and buried to <br />allow an alternative point of supply for the water system. A trench, shown on Map 24, will be excavated to allow <br />connection of the new fresh water supply borehole to the existing water supply line, and to connect the two boreholes. <br />The topsoil will be se[ aside, the overburden removed, and the tie in line will be laid in the trench. The trench will be <br />backfilled, the topsoil replaced and the site seeded. In order to allow for long teen access [o the borehole a 72" <br />culvert +aill be placed around the well head. It is anticipated the 72" culvert will be installed later in the spring, and <br />until i[ is installed a pi[ will remain around the borehole. Upon abandonment of the system the hole will be grouted <br />and the culvert pulled. The void remaining from the culvert will be backfilled by the overburden [hat had been <br />pushed up around i[. The site will be seeded in the fall, or firs[ available growing season. <br />Another portion of the system, as shown on Map 24, will be utilized to supply water to the mine. A pump, 30" <br />borehole and pumphouse will be placed at [he site 114 spring, and a water line will be buried from the pump over to <br />the million gallon tank and borehole. The line will be buried to an approximate depth of seven feet. In order to <br />facilitate [he installation of this line, topsoil may be bladed to the side to pro+'ide an acceptable +vork area. The <br />current temporar}' access road will be upgraded with gravel [o allow year-round access to the pumphouse, with the <br />topsoil being windrowed to [he side of the pad. The original borehole cul+'ert will be backfilled with ++'ashed rock <br />within I foot of the existing overflow point leading to [he Site 114 flume. This will provide a reserve diversion point <br />should problems develop with the 30" borehole. <br />• A power line will be installed from the corner of Colorado Yampa Coal Company's equipment parking lot to the <br />pump located at the sprang. This will require the installation of 3 - 4 power poles between the parking lot and the <br />pump. A mobile rig will be utilized to install the poles. Alternatively, TCC may tie into an existing buried power <br />supply line and extend it some I50 feet to [he proposed pumphouse. A minimal amount of digging will be necessary <br />to allow testing of the existing line and burial of any extension in [he previousl}' disturbed area. During the interim <br />period, a diesel powered generator will be used to run the pump. The generator will be set on the road leading to the <br />PM bay, and a cable will run from it [o the pump. As soon as [he power line is installed [he generator will be taken <br />out of service. <br />When the mine first experienced a water shortage equipment w'as brought into the spring area to deepen the spring <br />and remove the flume from the spring's outlet. This resulted in a minor amount of disturbance to the reclaimed site <br />when the snow was pushed out of the way. When ground conditions allow the disturbed area will be smoothed and <br />reseeded if necessary. Likewise, the material excavated from the spring will be stabilized or placed back into the <br />excavated hole. If the spring is to be utilized for more than six months a fence will be constructed around the spring <br />to keep animals out of the spring. <br />If the road into the site is continued to be used while the ground is soft the topsoil will be bladed to the side and <br />stabilized with the temporary seed mix. Upon abandomnent of this system the topsoil would be redistributed over the <br />site and seeded with the approved seed mixture. <br />TCC also proposes to temporarily divert the portal mine discharge from Site 109 to Si[e 114 in order to augment the <br />emergency ++'a[er supply to the million gallon tank. This will in+'olve routing Si[e 109 Flo+vs upslope toward the <br />operation center by means of a 6" diameter line lying on the surface. Water discharged from this pipe will then Flow <br />. to the Si[e 114 pump by means of the existing ditches and culverts. A short temporary ditch may need to be inscribed <br />fiom the Pl+9 road cuh'ert to Si[e 114 in order to route the Flow to the pump. When no loneer required, [he overland <br />lice will be disconnected allowing the 109 discharge to again flow to Pond D, and the temporary ditch +vill be <br />removed. <br />MR 97- I i4 2.0~-52 Revised 9/9/97 <br />
