<br />5 <br />onto the side of the hill. The area is about 2500 feet downgradient of <br />pond HG-8, along the west side of County Road 53. A small excavation <br />at the top of the pile, made during the October 9, 1996 bond release <br />inspection, indicated a layer of topsoil overlying fill material. <br />Topsoil stockpile C did not need to be regraded. <br />Pond 3, the regraded ponds 1 and 2, and the corridor leading to pond <br />1 are included in this partial Phase One bond release. Pond 3, the <br />shop pond, was designated as a permanent impoundment, as was stated in <br />a letter from the Division dated November 25, 1985. Data supplied by <br />the operator, in the bond release submittal and in annual hydrology <br />reports, show that the pond 3 discharge meets compliance limitations. <br />Pond 1, the explosives storage area pond, and pond 2, the landfill <br />area pond, were reclaimed in the fall of 1996, after appropriate <br />demonstrations for removal were approved in Minor Revision No. 10. The <br />demonstrations showed that the disturbed area runoff could meet <br />sediment compliance limits without the use of sedimentation control <br />structures. The corridor leading to pond 1 did not have to be <br />regraded. There are several temporary collection and diversion ditches <br />on site. The locations are shown on Map 1, entitled "Facilities Area <br />Reclamation Map", of the bond release submittal. The ditches are <br />functional and are well vegetated. <br />The facilities area, including the explosives storage area, was <br />regraded in the fall of 1987, except for the sanitary landfill, which <br />was backfilled in late fall of 1982. The facilities area, the regraded <br />ponds 1 and 2, the pond 1 corridor and the three former topsoil <br />stockpile areas were regraded to approximate original contour (AOC). <br />This determination was based on the field inspection of October 9, <br />1996 and comparison of the permit application's approved postmining <br />contour map, Exhibit D, "Final Reclamation Map", with the as-built <br />topography, as shown on the bond release submittal Map 1, entitled <br />"Facilities Area Reclamation Map." Map 2, "Facilities Area Post-Mining <br />Cross-Section Map", supplied in the operator's bond release submittal, <br />was also used in this determination of AOC. There were no variances <br />from the AOC requirements. Field inspection verified that no highwalls <br />remain and that the backfilled slopes are stable. <br />Drainage reestablishment was determined, through field inspection and <br />data analyses, to be successful. The bond release inspection of <br />October 9, 1996 showed that the regraded drainage characteristics, <br />including slope lengths and gradients as well as drainage density, <br />blended in with the surrounding, undisturbed, drainage patterns. <br />Further, no erosional instability or signs of .mass instability were <br />observed at any of the areas proposed for partial Phase One bond <br />release. <br />Comparisons were made between the premining topography, as shown in <br />Exhibit B, "Premining Map", the approved postmining topography, as <br />shown on Exhibit D, entitled "Final Reclamation Map", and the as-built <br />postmining topography, as shown on Map 1, entitled "Facilities Area <br />Reclamation Map", of the bond release submittal. These comparisons <br />complemented the findings in the field of successful drainage <br />reestablishment. <br />
