EASTSIDE MINE <br />Summary of 2000 Water Monitoring <br />Extent of Minine <br />No mining has occurred at the Eastside Mine since December 1994. The buildings and surface facilities <br />were removed from the minesite, the portals were sealed and surface area was regraded in May, June <br />and July of 1995. Eastside Coal Company requested and was granted a Phase I Bond Release in <br />December of 1995. In September of 1995 the disturbed area was seeded with the approved seed mixture <br />as listed in the approved Mining and Reclamation Permit. The area is inspected on a quarterly basis fo <br />ensure the stormwater management plan and sediment control system are functioning properly. The <br />sediment control system was removed and reclaimed in December 2001. <br />Flow and Field Parameters <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 />6.5 to 7.5. The Above Mine conductivity ranged from 506 to 681 microohms/cm. Above Mine <br />Temperature ranged from 5.1 to 20.4 degrees centigrade. The Below Mine pH ranged from 6.5 to 7.5. <br />Below Mine conductivity ranged from 508 to 813 microohms/cm. Below Mine temperature ranged from <br />0.3 to 19.6 degrees centigrade. The Seep pH ranged from 6.5 to 7.5. Seep conductivity ranged from 861 <br />to 970 microohms/cm. Seep temperature ranged from 0.2 to 18.3 degrees centigrade. No significant <br />deviations from the 1996-1999 field data were noted. <br />Chemical Parameters <br />The chemical parameter results of the Harvey Gap Outlet above the mine and below the mine generally <br />fall within the ranges established 1985-2000. The averages of all the samples taken indicate that <br />Conductivity is higher than previous years. The average value of the Dissolved Calcium has also <br />increased. <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 discharge has occurred from sediment pond SP-1 or from the underground mine workings. <br />The water monitoring data are 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 2001 data with 1996-2000 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 1996-2001 data which was compared are on pages I 1 <br />through 16. <br />Page 3 of 16 <br />
