If so, the material will be removed and hauled to the refuse pile or pit for disposal. The pond is inspected during <br />CDPS sampling and the v-notch weir is checked to determine if it is functioning correctly. Repairs are made on an <br />as-needed basis. The pond is also inspected quarterly to assess the condition of the embankment and spillways and <br />to determine if it is functioning correctly. Repairs aze made on an as needed basis. The pond will be removed <br />when it is no longer needed. The outlet works will be removed, the embankment pushed back into the pond <br />excavation and final graded to blend with the surrounding terrain, and the azea will be topsoiled and revegetated. <br />Sedimentation Pond F receives runoff from the surface facilities, reclaimed surface mine, spoil springs, and <br />underground mine discharge. TCC will survey the pond as per the previously outlined schedule. The same criteria <br />will be used to detemmne if the pond requires cleaning. If so, the material will be removed and hauled to the refuse <br />pile or pit for disposal. The pond is inspected during the periodic CDPS sampling, and the condition of the <br />measuring device is checked. Repairs are made on an as-needed basis. The measuring device is a cutthroat flume <br />located upstream of the road culvert. The weir, previously used to measure flows, did not function properly and <br />required significant maintenance, so a 12-inch cutthroat flume was installed to assure accurate flow measurements. <br />The pond will be removed when it is no longer needed. The outlet works will be removed, the rock in the <br />emergency spillway maybe reclaimed or placed in the pond basin, the embankment will be pushed in and graded to <br />blend with the surrounding terrain, and the area will be topsoiled and revegetated. <br />Sedimentation Pond G receives runoff from a part of the surface facilities and the reclaimed surface mine. TCC <br />will survey the pond per the previously outlined schedule. The same criteria 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. The pond is <br />inspected during the regulaz CDPS sampling and the flume is checked to determine if it is functioning correctly. <br />Any problems are noted and repairs made as-needed. Pond G is also an MSHA pond, subject to regular monthly <br />inspections, except during the winter months. For the MSHA inspections, the outlet works and pond embankment <br />aze inspected, and any necessary repairs made in a timely basis. The pond will be removed when it is no longer <br />needed. .The outlet works will be removed, the rock in the emergency spillway may be reclaimed or placed in the <br />pond basin, the embankment will be pushed in and graded to blend with the surrounding terrain, and the azea will <br />be topsoiled and revegetated. <br />Pond T receives runoff from the explosives magazine and storage yard areas. TCC will survey the pond per the <br />previously outlined schedule. The same criteria will be used to determine if the pond requires cleaning. If so, the <br />material will be removed and hauled to the refuse pile or pit for disposal. The pond is inspected during the CDPS <br />sampling, and the weir is checked to see if it is working correctly. Any problems are noted and repairs made as <br />needed. The pond will be removed when it is no longer needed. The outlet works will be removed, the rock in the <br />emergency spillway may be reclaimed or placed in the pond basin, the embankment will be pushed in and graded to <br />blend with the surrounding terrain, and the azea will be topsoiled and revegetated. <br />Fish Creek Borehole Treatment Facility (ModiTied and Superceded by MR06-207, Electro-Coagulation <br />System) <br />Three treatment cells were constructed for treating mine discharge water from the Fish Creek Borehole. The <br />location and cross-sections for the Treatment Facility are shown on Maps 26 and 32, Fish Creek Borehole Area <br />Facilities and Access Road, and Fish Creek Settling Pond Plan View and Cross-Sections. The design for the <br />culverts for the Fish Creek 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.
