• The fact that no mixing of surface drainage with a discharge from underground <br /> workings will occur. <br /> The SAES are/were located at: <br /> • West Mine fill outslopes (now replaced by two sediment ponds) <br /> • The West Mine vent fan site <br /> • Training trailer area outslopes (now reclaimed) <br /> • The loadout area railroad outslopes <br /> • The main facilities fan area(now reclaimed). <br /> For details regarding SAES, see the following in the mine records: <br /> • Section 2.05 in Volumes 1 and 7 of the PAP <br /> • Map 7 in Volume 7 <br /> • Volume 8 of the PAP, including Maps 8-IA, 8-2, 8-6, and 8-7 <br /> • Small Area Exemption Demonstrations from TR-20. <br /> Stream Channel Diversions <br /> A clean water diversion above the main facilities area of the East Mine directs undisturbed <br /> area flow around the facilities area to minimize surface water flow through that site. A <br /> similar clean water diversion ditch existed above the facilities at the West Mine portal <br /> bench area. However, due to reclamation operations at that site, the clean water diversion <br /> ditch was reclaimed. A system of lined and unlined ditches conveys waters from the <br /> disturbed areas to the sediment ponds. Design details can be found in the PAP, Volumes <br /> 6, 8, and 8A. <br /> In order to minimize water quality impact to water flowing through the West Mine area, <br /> water in East Roatcap Creek is diverted to West Roatcap Creek via the Overland Ditch. To <br /> verify that no water is lost, surface water monitoring point SW-09 was moved to, and is <br /> currently monitored at, the point of the diversion from East Roatcap Creek. <br /> Because of limited space at the West Mine, East Roatcap Creek was diverted through a 48 <br /> inch diameter culvert so that the West Mine portal bench could be built over the creek. <br /> When the mine bench was reclaimed, the East Roatcap Creek culvert and about 10 feet of <br /> cover soil were left in place. Two sediment ponds were built over the creek culvert for <br /> sediment control until the upper portion of the West Mine bench stabilizes with vegetation. <br /> Once this upper portion becomes stabilized, the buried culvert will be removed and the <br /> East Roatcap Creek will be reconstructed. <br /> Acid-Forming and Toxic-Forming Spoil <br /> No acid-forming or toxic-forming materials have been identified at the Bowie No. 1 Mine. <br /> Impoundments <br /> All site impoundments are in compliance with Rule 4.05.9, as discussed above. <br /> 24 <br />
