exponentially from the original 2 to 3 gallons per minute to 0 gpm as the water table rises in the reclaimed pit. Since there will be no mining activity below the water table in the Federal Lease Area, there should be no effect on the ground water table or flows in Stollsteimer Creek due to mining in that area. In summation, the total amount of water withdrawn from Stollsteimer Creek during and after the mining activities in the East Pit, Barren Ridge, and Federal Lease Areas due to pit inflows will have a negligible effect on the normal flows of Stollsteimer Creek. After the spoil aquifer has been fully recharged, a mound of ground water will begin to develop in the spoils. Eventually the spoil aquifer will begin to discharge water to the bedrock aquifers, stream alluvium, and ultimately to Stollsteimer Creek. The rate of spoil water discharge will be a function of the recharge rate (infiltration and deep percolation rates) of the reclaimed spoils. The estimated recharge rate for the 13 acres of reclaimed spoils over the East Pit spoil aquifer is 1 gallon per minute (gpm). Therefore, the rate of discharge from the spoil aquifer will be less than 1 gpm for the East Pit. A calculation of the discharge rate for the spoils aquifer developed in the Barren Ridge Area has also been estimated to be less than I gpm. Given a mean value for spoil water quality of approximately 5,000 mg/I for TDS (data from other surface mines in the state), a mean value for alluvial water quality of approximately 650 mg/I for TDS, an estimated flow rate within the alluvial aquifer of 55,555 gpm across the alluvial valley floor, and a flow rate from the two spoils aquifer of 2 gpm, the total degradation which would result from the two spoil aquifers will be 0.03 percent or an increase of 0.18 mg/l TDS. These estimates are based on average or linear flow situations, whereas under actual field conditions, the increased TDS levels would be concentrated in the area of the greatest amount of spoil material. However, it is believed that the above-projected estimates are close to the potential actual field conditions and, with the projected increases in TDS levels as low as those given here, the potential impacts would be negligible. These projected TDS levels are similar to those derived from a study done on the Barren Ridge Area by Piteau Associates. This study concluded that both the water quality and water quantity in Stollsteimer Creek would be impacted by less than one percent (Piteau Report, September I5, 1983, Exhibit 38, Federal Lease permit revision application). The above information is sufficient to show that potential changes to water quantity or quality will be negligible and, thus, there will be no material damage on site or off site to the water recharging the AVF. 18
