Powerlines (Replacement Power Poles and Fiber Optic Line) - PSCM will construct required <br />power distribution lines within existing road easements, where feasible to minimize disturbance. <br />Where it is necessary to construct new lines outside existing road easements, PSCM does not <br />intend to develop new roads for line construction or maintenance. Line construction equipment <br />will minimize surface disturbance by driving overland to pole locations, with construction <br />activities scheduled to take advantage of favorable ground conditions. In the event that surface <br />disturbance is unavoidable, available soil materials will be windrowed to the side, prior to <br />disturbance, with the soil being pulled back over the disturbed area and reseeded on completion of <br />construction activities. <br />There have been approximately 9,100 feet of replacement powerline constructed. <br />Powder Magazines — Two (2) powder magazines have been placed near the PECOCO <br />Embankment Road. They are metal /wood lined and measure 16'xl2'x10' and 12'x8'x8'. These <br />structures will be barricaded and have a distance of at least 50, between them. The pad for the <br />magazines will measure 150' by 75'. Topsoil will be removed from the pad site and stockpiled <br />then fabric will be placed on the ground along with gravel to help control weeds. Weeds will be <br />controlled as outlined in PSCM's Weed Management Plan. The pad will also be surrounded by <br />a 12' chain link fence. The location of the magazines can be seen on Map 2.05.3 MIA, Mine <br />Facilities Map (South End). To access-these magazines, a small access road will be built. This <br />will be the PECOCO Embankment Road and can also be seen on Map 2.05.3 MIA. <br />Spoil Water Dewatering Well — A dewatering well will be constructed to reduce the water <br />inflow into the future underground mine workings. Two options are being considered to remove <br />the water; only one option will be implemented. <br />One option for this well is located approximately 100' north of the fan discharge point. It will be <br />a horizontal borehole in the highwall of the portal area, and water will gravity flow to the portal <br />sump. The borehole will be 8 5/8" in diameter and up to 300' deep, depending on the depth <br />needed to reach the spoils. The borehole will then be lined with HDPE _ pipe and ,a well head <br />attached to the-end. <br />Another option is for a well to be constructed on the north end of the coal stockpile pad. An <br />access road would be constructed to a 150'x100' drill pad with a cuttings pit. The hole would be <br />approximately 90' deep and the diameter would be between 18" to 36" depending upon ground <br />and drilling conditions. Once drilling is complete, a concrete pad (20'x10'xl') would be poured <br />and a small, metal structure would be constructed to house the pump and well opening. The <br />access road would be left in place after drilling is completed to facilitate maintenance on the well <br />and pump. The pump would be capable of producing up to 150 GPM depending on water depth <br />within the well. The water from the well would be piped to the upper smart ditch above the portal <br />and flow into the lower sump. These structures were constructed to have excess capacity than is <br />necessary by design. <br />MR -15 2.05 -17 Revision 10/2012 <br />
