RULE 2 - PERMITS <br />• Building Cleanouts <br />• New Septic Tanks — One 1,000 gallon, single- compartment, precast concrete tank will serve <br />as the primary septic tank for both bath houses and will be followed by a 1,000- gallon, pre- <br />cast concrete, two - compartment tank that will serve as the dosing tank. Primary treated <br />effluent from the septic tank will gravity flow to the 1,000 - gallon dosing tank adjacent to the <br />drainfield. <br />• Septic Drainfield — The drainfield consists of two, 11.3 ft by 68 ft long chambered sections. <br />Runoff from the area disturbed will be directed to the Shop Diversion Ditch which reports to <br />Pond 003. During Construction, BMPs (e.g. wattles, berms, etc.) will be employed to direct <br />the runoff and control runoff and sedimentation from entering the adjacent undisturbed area. <br />The existing drainfield, located to the southwest of the existing bath house will remain in place, but be <br />converted, through re- plumbing to accept the backwash from the existing water softener. The new <br />drainfield setback is 100 feet from Little Grassy Creek which meets the CDPHE and Routt County <br />setback restrictions. The locations are shown on Map 2.05.3-Ml B. <br />Pond 002 Pump Facility - The existing pump station/water horse will be replaced with an updated <br />system. The pump facilities will include an improved, graveled ramp approximately 15 feet wide <br />and 150 feet long. At the end of the ramp, an area 20 feet by 20 feet will be leveled, and precast <br />concrete blocks will be placed at the edge of the water to prevent bank erosion. A floating dock <br />system will be attached to the precast concrete blocks to support a submersible pump. The pump <br />will be a 150hp pump and will connect to a 10" HDPE pipe on the floating dock system. A <br />building will also be constructed to house various connections and valves. The building will be <br />metal and measure 20' x 12' with an 8' deep foundation. The foundation walls will be 10 " while <br />the floor will be 6" thick; both will be made of re- enforced concrete. <br />Propane Tanks — Portable 1,000 gallon propane tanks (5) are planned to be placed at various <br />locations at the North Facilities area. See Map 2.05.3 -M1B for locations. A sixth 18,000 gallon <br />tank will be placed near the Waste Handling and Recycle area to supply the mine heaters. <br />Supplemental/Replacement Water Well CCU087— A supplemental /replacement domestic water <br />well has been drilled to accommodate the new bath house in addition to the office facilities. The <br />new well will supplement/ replace the existing well and contain a new pump and chlorination <br />system. PSCM drilled a test hole (755' x 5 5/8 ") approximately 100' west of the existing well to <br />check for a viable source of water. <br />This water well has been completed, and a permit was obtained from the State Engineer's Office. A <br />copy of the issued permit can be found in Exhibit 2.04.7 -E1, Hydrologic Information. <br />Replacement Power Poles and Installation of Fiber Optics Line - There is an existing 4,160 V <br />line running from the YVEA substation to the Sage Creek Office and facilities. The condition of <br />the poles and associated power infrastructure is poor and unable to accommodate needed fiber -optic <br />lines. PSMC proposes to replace the poles and line moving away from their current location along <br />Little Grassy Creek. The line location is shown on Map 2.05.3 MIA and B Mine Facilities Maps — <br />South End and North End. New fiber -optic lines will also be installed on these poles along the new <br />route. The existing poles will be removed. In addition, a new line will be installed to convey 69 kV <br />from the YVEA substation to the new portal substation. <br />MR17 -13 2.05 -12 Revision 02/2013 <br />
