CY) and PPSP-1(6,420 CY). The 4,170 CY of plant growth media placed in stockpile PPSP-2 will be redistributed <br />over the area from which it was removed. <br />During review of TR94-18, a concern was raised over the postmining elevation, and if the foundation would be <br />below grade. The bond for the technical revision was established using the worst-case estimate that the foundation <br />would have to be removed and the site then regraded. The map and certification presented in Exhibit 26B, <br />Postmining Topography Evaluation, shows that the foundation could be at the surface upon completion of final <br />grading, however given the ability to fine tune the grading plan in the field, it would be possible to keep the <br />foundation three feet below grade. As opposed to modifying the bond or the present reclamation plan, it is TCC's <br />intent to have the foundation removed prior to final grading. TR 02-40 provides the updated bond estimate for <br />removing the piers at the Washplant I facilities. This includes the Washplant, Refuse Bin, Thickeners, and two <br />magnetite bins. This final bond estimate addresses Stipulation 46 presented in the Mid -Term Permit Review. <br />Fish Creek Ventilation and Dewatering Borehole (Revised - MR07-216 <br />The Fish Creek Ventilation Borehole/Dewatering Site will require a minor amount of work in order to reclaim the <br />site. The work includes: fan, fan control equipment, fan building, and duct -work removal (previously completed); <br />pumphouse removal; demolition of concrete pads and removal of concrete demolition debris; plugging and sealing <br />of the well bore and casing; stubbing -off and capping buried piping; powerline removal; road removal; and topsoil <br />replacement and seeding. <br />The Fish Creek Ventilation installation had a useful life of approximately seven years, until the first set of longwall <br />panels were mined -out. The fan building, duct -work, and fan have been removed from the site. The borehole was <br />temporarily sealed, as described in the response to Rule 2.05.4(2)(g), and was used only for discharge from the <br />excess flow diversion line from the Fish Creek water treatment system. In 2007, the shaft installation was modified <br />for use as a dewatering well to replace the inoperable Fish Freek South Dewatering Borehole. At the time of final <br />reclamation, the pumphouse for the dewatering well will be removed, the connecting pipeline will be stubbed -off <br />and capped below grade, the connecting powerline will be removed, and the concrete pads will be broken up and <br />the concrete removed from the site. The concrete demolition debris will either be hauled to the refuse site for <br />disposal or hauled to a landfill. <br />Final reclamation of the 36 -inch diameter casing will involve excavating down 4 feet from grade around the casing, <br />cutting off the steel casing 3 feet below grade, hanging steel decking from the top of the cut-off casing (this decking <br />will be 30 feet below the top of the cut-off casing), placement of 30 feet of concrete in the 36 inch diameter casing, <br />and backfilling the excavated area. The 30 foot x 3 foot diameter cement plug will weigh approximately 32,000 <br />pounds, which will be adequate to resist the calculated hydrostatic pressure and provide an effective seal. The <br />access road will be graded to blend with the surrounding terrain, and the culvert will be removed. The entire area <br />will be topsoiled and seeded with the appropriate seed mixture. <br />TR18-91 2.05-103 08/20/18 <br />
