Kerr Coal - 2004 Annua! Hydrology Report <br />7.0 LOADOUT AREA SURFACE WATER <br />February, 2005 <br />Two loadout surface water sites (319 and 320) were monitored weekly from March through June, then <br />monthly through September, 2004. There was no recorded dischazge from Site 319. There was dischazge <br />from Site 320 from June 15 to July 1, 2004 ranging from 0.5 to 1.5 cfs. The 1.5 cfs readings were the highest <br />flows historically recorded for this site. No flow was observed afrer July 1 at Station 320. The sedimentation <br />pond associated with Site 320 filled during spring runoff and retained some water through September. Site <br />monitoring locations are shown on Map 2, Loadout Area Monitoring Stationt. <br />As of January 1999, the monitoring program for surface discharge points was reduced to monthly monitoring <br />for a parameter list including only flow, temperature, pH, settleable solids, and oil and grease. For Site 320, <br />only the field measurements (flow, temperature and pH) aze required for monitoring. This data is contained <br />in Appendix A, 2004 Field Data. The historic flow data for the Loadout is presented on Table 6, 2004 Surface <br />mater Data - Loadout Area Surface Statzonr. Figure 6, Flow and pH -Station 320, shows the variation in flow <br />and associated pH reading at Station 320 for all historic flows measured. <br />Surface water sites 316, 317, and 318 were dropped from monitoring as of October 1999. No data was <br />collected from these sites during the 2004 water yeaz. <br />TABLE 6 <br />2004 SURFACE WATER DATA <br />LOADOUT AREA SURFACE STATIONS <br /> 05/13/02 06/05/02 06N3/02 06/19/02 SN5/03 5121/03 528103 6115/04 6123/04 711/04 <br />STATION 319 <br />Flow Rate cfs No Flow No Flow No Flow No Flow No Flow No Flow No Flow No Flow No Flow No Flow <br />Tem nature C <br />H -field s.u. <br />EC-field umhos/cm <br />Oil & Grease <br />Settl~ble Solids <br /> <br />STATION 320 <br />Flow Rate cfs 0.20 0.15 0.05 0.05 0.50 1.00 0.50 0.50 1.50 1.50 <br />Tem nature C 12 12 17 15 13 14 22 13 78 17 <br />H -field s.u. 8.1 8.0 6.0 7.8 6.0 6.0 8.1 8.0 8.0 8.0 <br />EC-field umhos/cm 300 400 300 300 400 400 300 400 200 200 <br /> <br /> <br />
