Peabody Energy <br />• a. Excavation: <br />At the diesel storage tank approximately 48 yards of earth will need to be excavated for the spill catchment <br />basins and fueling pads. Excavated material may be disposed of by trucking it to the refuse disposal area <br />on site. <br />b. Soil Preparation: <br />Prior to concrete work the soils, which consist of unconsolidated fill material (including shales and <br />claystones), should be wetted to within 2% of optimal moisture content and compacted (to a depth of one <br />foot) to at least 100% of maximum standard proctor density. <br />c. Piping: <br />A six inch DR11 HDPE pipe shall be run from the corner of the smaller basin to the large basin (as <br />indicated in Drawing #070810A). <br />d. Concrete: <br />The 8,000 gallon, main spill catchment basin, as per Drawing #070810A, is to be poured to a depth of 6 <br />inches. This concrete is to be reinforced with a single mat of #5 rebar on 12 inch centers. Reinforcing bars <br />shall conform to ASTM Specification A615 -79 and shall be grade 60. At splices, overlap bars 36 diameters <br />and at corners or intersections bars should either be continuous or provide matching corner bars. <br />The accompanying filling pad is to be poured to a depth of 12 inches. See Drawing #070810A for layout. <br />This concrete should be slightly sloped towards the basin and to the center in order to ensure fuel spills <br />drain to the basin, not the earth surrounding the pad. It is to be reinforced with a vertically centered mat of <br />#5 rebar on 8 inch centers. All reinforcing bars shall conform to ASTM Specification A615 -79 and shall be <br />at least grade 60. At splices the bars shall be overlapped 36 diameters. At corners and intersections the <br />bars shall be continuous or matching corner bars shall be provided. <br />The smaller, 725 gallon, catchment basin for equipment fueling spills and leaks from the fuel nozzles is to <br />• be poured to a uniform depth of 4 inches of concrete. It is to be reinforced with a mat of #5 rebar on 8 inch <br />centers. Reinforcing bars shall conform to ASTM Specification A615 -79 and shall be grade 60. At splices, <br />overlap bars 36 diameters and at corners or intersections bars should either be continuous or provide <br />matching corner bars. Once completed, this basin is to be covered with welded steel grating. <br />The smaller basin's companion fueling pad is a 13' by 20' slab, to be poured to a depth of 12 inches. This <br />pad is to be sloped towards the catchment basin to ensure proper spill drainage. It is to be reinforced with a <br />vertically centered mat of #5 rebar on 8 inch centers. All reinforcing bars shall conform to ASTM <br />Specification A615 -79 and shall be at least grade 60. At splices the bars shall be overlapped 36 diameters. <br />At corners and intersections the bars shall be continuous or matching corner bars shall be provided. <br />All concrete shall have a minimum 28 day compressive strength of 3000psi, Type 1. <br />e. Grading: <br />After the pad and basin have been poured, the area surrounding shall be re- graded and sloped to restore <br />proper drainage of precipitation and runoff water. Once the concrete has been allowed to cure for at least <br />one week concrete k -rails (jersey barriers) shall be placed, as shown in Drawing #070810A, around the <br />perimeter of the large catchment basin. Additionally 1 3 /4" by <br />3/16" (capacity of 181lbs per square foot) steel grating shall be placed over the smaller catchment basin. <br />4. ROM Pile Diesel Storage Tank: <br />The ROM pile diesel storage tank is located southwest of the Run -Of -Mine coal stockpile and is primarily used by <br />dozers pushing the stockpile (see Drawing #0708101 and Picture #070910D.) As this tank is used almost <br />exclusively by dozers, TCC has decided to install a leach field and oil -water separator as a secondary containment <br />system. The fuel tank is an older, single - walled, vessel with a steel basin to serve as secondary containment. TCC <br />has the ability to store up to 10,000 gallons of diesel fuel at this location. <br />• a. Excavation: <br />SLC- 5537792 -7 10 <br />
