<br /> <br /> <br /> <br />correctly. Repairs are made on an as needed basis. The pond is inspected quarterly to determine the <br />condition of its' embankment and spillways. Repairs are made as needed. <br />The pond will be removed when it is no longer needed. The outlet works will be removed and the <br />embankment graded back into the pond excavation. The area will be final graded so that it blends in with <br />surrounding area. The area will be topsoiled and seeded. <br />Pond F receives runoff from the surface facilities, reclaimed surface mine, spoil springs, and underground <br />mine discharge. TCC will survey the pond as per the schedule given above. The same criteria given above <br />will be used to determine if the pond requires cleaning. If so, the material will be removed and hauled to the <br />refuse pile or pit for disposal. <br />The pond is visited during the periodic NPDES sampling and the condition of the measuring device is noted. <br />Repairs are made on an as needed basis. The measuring device is more a cutthroat flume that is located <br />upstream of the road culvert. The weir encountered problems and the last fix was to install the 12" cutthroat <br />flume to ensure accurate flow measurements. <br />The pond will be removed when it is no longer needed. The embankment will be graded in and the outlet <br />works removed from it. The stone in the spillway will either be reclaimed or placed in the pond excavation <br />as part of the backfill. The area will be graded to blend in with the surrounding topography, topsoiled and <br />seeded. <br />In reference to Pond G, it receives runofffrom a part of the surface facilities and the reclaimed surface mine. <br />TCC will survey the pond as per the above schedule. The same criteria given above will be used to <br />determine if the pond requires cleaning. If so, the material will be removed and hauled to the refuse pile or <br />pit for disposal. <br />In reference to Pond T, it receives runoff from the magazine and storage yard area. TCC will survey the <br />pond as per the above schedule. The same criteria given above will be used to determine if the pond requires <br />cleaning. If 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. <br />The pond will be removed when it is no longer needed. The embankment will be graded in and the outlet <br />works removed. The stone in the emerging spillway will either be reclaimed or placed in the pond <br />excavation as part of the backfill. The area will be graded to blend in with the surrounding topography <br />topsoiled and seeded. <br />FCB Treatment Facility <br />Three treatment cells were constructed for treating mine discharge water from the Fish Creek Borehole. The <br />cells location and cross-sections are shown on Maps 26 and 32, Fish Creek Borehole Area Facilities and <br />Access Road, and Fish Creek Settling Pond Plan view and Cross Sections. The design for the culverts for the <br />Fish Creek Borehole Access Road is presented in Exhibit Sr. <br />The facility will consist of 2 adjacent dewatering wells, three treatment cells, chemical feed stations (sodium <br />hydroxide and sulfuric acid), substation, access road and powerlines. The pumps will be located <br />immediately above the coal roof (in the boreholes) and electricity will be supplied by the <br />APPROl1~~ ,)uN 2 s 2000 <br />PR 99-OS <br />2.05-76.2 <br />05/03/00 <br />
