grade. The reclamation plan for this area specified the removal of the gravel and the replacement of <br />topsoil on the pad. EFCI removed the gravel as required prior to topsoil replacement. Regrading was <br />not necessary since the pad was originally constructed without changing the pre-mine topography. <br />Pond 3: Pond 3 was an incised, lined pond that was used to store fresh water from the Corley Mine <br />Well to be used in the coal prepazation plant. The pond was not part of the sediment control system <br />and, as such, removal of the pond was required at reclamation. The disturbed azea of the pond was <br />originally 1.41 acres. After backfilling and regrading the pond, the disturbance totals 2.47 acres. The <br />increase in acreage is due to heary equipment moving around the area. <br />During the 13 November inspection, the Vento property owners were dissatisfied with the final grade <br />of the azea. Several tree `islands' had been left in place. These tree islands were volunteer trees that <br />had become established on the embankment after its initial construction. Concern was expressed as to <br />whether or not AOC had been achieved in this area. The landowners were also concerned about the <br />drainage grade through the azea, the discharge from the azea and a PVC pipe that had been left in place. <br />On 5 December 2002, the Division surveyed the Pond 3 area to determine whether AOC had been met <br />and to determine the drainage grade through the area. The following chart shows the four corners of the <br />area and their premining elevations, postmining elevations and the difference in elevation. <br />Location Pre Elevation Post Elevation Difference <br /> <br />NE Corner 6225' 6228' +3' <br />NW Corner 6250' 6245' -5' <br />SE Corner 6255' 6255' 0' <br />SW Comer 6255' 6255' 0' <br />The distance between the northeast and northwest comers of the disturbance is approximately 400 feet, <br />with a post mining decrease in elevation of eight feet. The resulting postmining gradient is 4.25%. <br />The premine gradient was 6.25%. This indicates that the postmining topography is both similar and <br />less steep than the premine topography. This minor reduction in gradient will support erosional <br />Southfield Mine Permit No. C-1981-014 <br />SL-2 Findings 21 25 April 2003 <br />
