EASTSIDE MINE <br />Summary of 2003 Water Monitoring <br />Extent of Minine <br />No mining has occuned at the Eastside Mine since December 1994. The buildings and surface facilities <br />were removed from the minesite, the portals were sealed and surface azea was regraded in May, June and <br />July of 1995. Eastside Coal Company requested and was granted a Phase I Bond Release in December <br />of 1995. In September of 1995 the disturbed azea was seeded with the approved seed mixture as listed <br />in the approved Mining and Reclamation Permit. The azea is inspected on a quarterly basis to ensure the <br />stormwater management plan and sediment control system aze functioning properly. The sediment <br />control system was removed and reclaimed in December 2001. The area regraded was seeded in October <br />2002. <br />Flow and Field Pazameters <br />The flow and field parameters of the Harvey Gap Outlet above and below the mine continue to <br />demonstrate the seasonal dischazges from the Harvey Gap Reservoir. The Above Mine pH ranged from <br />6.0 to 7.6. The Above Mine conductivity ranged from 521 to 650 microohms/cm. Above Mine <br />Temperature ranged from 5.9 to 21.8 degrees centigrade. The Below Mine pH ranged from 6.0 to 7.6. <br />Below Mine conductivity ranged from 521 to 900 microohms/cm. Below Mine temperature ranged from <br />0.1 to 20.5 degrees centigrade. The Seep pH ranged from 6.5 to 7.6. Seep conductivity ranged from 832 <br />to 1067 microohms/cm. Seep temperature ranged from 1.7 to 13.4 degrees centigrade. No significant <br />deviations from the 1996-2002 field data were noted. <br />Chemical Pazameters <br />The chemical parameter results of the Harvey Gap Outlet above the mine and below the mine generally <br />fall within the ranges established 1985-2002. The averages of all the samples taken indicate that Sulfates <br />aze lower than previous years. The average value of the Dissolved Calcium increased slightly from last <br />yeaz but is more in line with previous yeazs. <br />There was no water dischazged from the four inch steel pipe installed in the portal seal from the Eastside <br />Mine. <br />Impacts on Surface and Ground Water <br />No dischazge has occurred from sediment pond SP-1 or from the underground mine workings. <br />The water monitoring data aze listed on the attached tables found in the Data and Statistical Information <br />section beginning on page 5 to and including page 10. A comparison of 2003 data with 1996-2002 data <br />indicates no measurable impacts on ground or surface water have occurred due to mining or reclamation <br />activities at the Eastside Mine. Tables with the 1996-2003 data which was compazed aze on pages 12 <br />Page 3 of 22 <br />
