The pond is visited during NPDES sampling and the v-notch weir is inspected to detemune if it is functioning <br />correctly. Repairs are made on an as needed basis. The pond is inspected quarterly to determine if it is functioning <br />correctly. Repairs are made on an as needed basis. The pond is inspected quarterly to detemune the condition of <br />• its' embankment and spillways. Repairs aze made as needed. <br />The pond will be removed when it is no longer needed. The outlet works will be removed and the embardanent <br />graded back into the pond excavation. The area will be final graded so that it blends in with surrounding azea. The <br />area will be topsoiled and seeded. <br />Pond F receives runoff from the surface facilities, reclaimed surface mine, spoil springs, and underground mine <br />discharge. TCC will survey the pond as per the schedule given above. The same criteria given above will be used <br />to determine if the pond requires cleaning. If so, the material will be removed and hauled to the refuse pile or pit <br />for disposal. <br />The pond is visited during the periodic NPDES sampling and the condition of the measuring device is noted. <br />Repairs aze made on an as needed basis. The measuring device is more a cutthroat flume that is located upstream <br />of the road culvert. The weir encountered problems and the last fix was to install the 12" cutthroat flume to ensure <br />accurate flow measurements. <br />The pond will be removed when it is no longer needed. The embartlanent will be graded in and the outlet works <br />removed from it. The stone in the spillway will either be reclaimed or placed in the pond excavation as part of the <br />backfill. The area will be graded to blend in with the surrounding topography, topsoiled and seeded. <br />In reference to Pond G, it receives runoff from a part of the surface facilities and the reclaimed surface mine. TCC <br />will survey the pond as per the above schedule. The same criteria given above will be used to determine if the pond <br />requires cleaning. If so, the material will be removed and hauled to the refuse pile or pit for disposal. <br />• In reference to Pond T, it receives runoff from the magazine and storage yazd area. TCC will survey the pond as <br />per the above schedule. The same criteria given above will be used to determine if the pond requires cleaning. If <br />so, the material will be removed and hauled to the refuse pile or pit for disposal <br />The pond is visited during the NPDES sampling and the weir is viewed to see if it is working correctly. Any <br />problems are noted and repairs made as needed. Also, this is an MSHA pond and subject to weekly inspections. <br />The outlet works aze inspected and repairs made as required. <br />The pond will be removed when it is no longer needed. The embanlanent will be graded in and the outlet works <br />removed: The stone in the emerging spillway will either be reclaimed or placed in the pond excavation as pars of <br />the backfill. The azea will be graded to blend in with the surrounding topography topsoiled and seeded. <br />FCB Treatment Facility <br />Three treatment cells were constructed for treating mine discharge water from the Fish Creek Borehole. The cells <br />location and cross-sections are shown on Maps 26 and 32, Fish Creek Borehole Area Facilities and Access Road, <br />and Fish Creek Settling Pond Plan View and Cross Sections. The design for the culverts for the Fish Creek <br />Borehole Access Road is presented in Exhibit 8r. <br />The facility will consist of two adjacent dewatering wells, three treatment cells, chemical feed stations (sodium <br />hydroxide and sulfuric acid), substation, access road and powerlines. The facility was modified in 2006 to replace <br />the sodium hydroxide treatment system with an electro-coagulation unit. The water supply pumps as set within the <br />dewatering wells immediately above the top of the coal seam in sealed mine workings in the Western Mining <br />District. Electricity will be supplied by the powerlines shown on Map 39, Powerline Location. <br />• <br />MR06-20'7 2.05-76.2 04/25/06 <br />
