• the. affected arc:,s. These beds are. much less per-:enble <br />and yield poorer quality water than the undcrlyin,~ <br />sandstones which would not be disturbed. Pfining, <br />therefore, should not significantly reduce the poten- <br />tial for future development of the ground-water ra- <br />source in the reclaimed areas. The additional test <br />of drilling deeper wells into sandstone beds unde=- <br />lying the Wadge coal is generally offset by higher <br />static water levels because of artesian conditions <br />i <br />' and better quality water. <br />No e::isting wells other than test holes within or <br />adjacent to the proposed lease areas would be removed <br />or adversely affected by mining. Loss of the see? <br />area inured lately south of C-22676 tract (`o. 7, cig. <br />2) would present no impact because of the nearby <br />1 <br />j stream. <br />The mined interval in all three tracts would be <br />j replaced by a mixture of spoil materials, the <br />' permeability of which would depend primarily on the <br />compaction resulting from the mining method. Over- <br />burden materials in tracts C-26644 and C-26913 would <br />be removed and replaced by draglines with conseq_ent <br />minimal compaction. These replaced spoils should be <br />~ moderately permeable as a whole faith no relatively <br />f impermeable ground-water perching layers. <br />! 122 <br />
