1994 AFIR Review Page 2 <br />January 25, 1995 <br />4. The sediment pond did not discharge during 1994; therefore, <br />observed changes in the Carbon Ditch cannot be attributed to <br />the mine. <br />5. The water level in the sediment pond piezometers remain <br />consistent with previous levels. <br />6. The conductivity of the seep in the pond has slightly <br />increased while the pH remains invariable. The source of the <br />spring is still unknown. <br />7. The level of water in E-i has risen as predicted in the Kaman <br />Tempo report, but is still below the elevation of the E <br />portal. The water level has risen to 6367.3 feet, which is <br />12.3 feet above the 1993 predicted level of 6355 feet. The E <br />seam portal is at an elevation of 6390 feet. The water level <br />is 22.7 feet below the elevation of the portal. <br />8. Water levels in the other coal seam wells appears to have <br />remained consistent with the exception of E-2, E-3, and D-3. <br />E-2 is adjacent to E-1 and results are similar. The D seam <br />should not be impacted by mining as the seam is below the <br />mined seam. The initial high water levels in the well is most <br />likely due to sampling error. The recent water level of 74.1 <br />feet is within the water levels obtained since July 1983. <br />While water levels in E-3 have been erratic, the well appeared <br />to have stabilized around 100 feet and is now at 165 feet. <br />Recommendations <br />1. Minrec should continue to sample for TDS and SAR in Ward Creek <br />on a yearly basis (September) to establish a pattern that <br />definitely shows the mine has no impact on the creek. While <br />TDS and SAR are still low, a determination cannot be <br />confidently made with one sample. A request of the Division <br />to cease collection of TDS and SAR in the future is required. <br />2. The Division concurs with Minrec to reinitiate sampling of E- <br />1. Sampling should be conducted on an annual basis during <br />September. A request of the Division to cease collection of <br />water levels in the future is required. <br />3. The Division recommends that sampling of E-3 be reinitiated as <br />well. As the water level appeared to have stabilized around <br />100 feet, the recent water level of 164.9 feet is curious. <br />Additional data would assist in determining if the mine is <br />impacting the well.. <br />
