and shaft liner were effective in stopping groundwater from entering the shaft. There is no flow at the bottom of the shaft. The quality of ground water that comes in contact with coal seams and surrounding strata is generally degraded. Bear Coal Company prepared a study of the potential effects of mining on the B -Seam aquifer (J. E. Stover & Associates letter to DMG dated October 23, 1995). A correlation was made between the geochemical characteristics of the roof, coal and interburden and the degradation of the quality of water in the coal seam. Soluble calcium, magnesium and sodium appears to degrade the quality of ground water that comes in contact with the disturbed coal seam and surrounding strata. This degradation of ground water quality is considered typical for water which seeps into the mines in the Paonia Somerset area. The quality of springs and seeps should not be degraded by the coal mining operation. As explained in Section 2.04.7, the primary source of water for the springs are unconsolidated quaternary deposits. These deposits should not be affected by the mine operation to the extent that the quality of the spring water would be degraded. • The quantity of water in the springs and seeps could be reduced by subsidence cracks. Subsidence cracks could intercept the impervious layer below the springs and seeps which would cause them to drain to the formation below. (a)(ii) Volume II, Map 23, Water Rights Location shows the water rights within the permit and adjacent area. Water right map codes 1, 2, 3, 4, 5, 11 & 32 are within the area that could be affected by mining. Map codes 1 through 5 are decreed water rights described as J & M Spring & PL No. 1 - 5. Map code 11 is the Leonard Springs. Map code 32 is the Bowie Spring No. 3. The Operator owns water right map codes1, 2, 3, 4, 5, 11 & 32. PR -12 APPRovE1� 11 1 VIO 2.05-101 06/10
