SECTION 2.05.6(3) <br />PROTECTION OF THE HYDROLOGIC BALANCE <br />This section is divided into discussions: one of the protection of the Hydrologic Balance and the <br />other of the Probable Hydrologic Consequences of mining. As of June'2001, significant data has <br />been collected over the years to make better predictions of both of these topics. <br />J PROTECTION OF THE HYDROLOGIC BALANCE <br />Introduction <br />Surface mining activities to be conducted at the New Horizon 2 mining area outlined in this permit <br />application have been planned to minimize impacts on the hydrologic balance. Mining, reclamation, <br />and monitoring plans and data reporting have been developed to be consistentwith the findings of <br />the Probable Hydrologic Consequences analysis presented at the end ofthis section. The following <br />discussion addresses mining, reclamation, and monitoring plans, and data reporting in the context <br />of how they relate to ground and surface water protection and monitoring. References to those <br />sections which contain details regarding mining and reclamation plans and practices have been <br />incorporated. Finally, discussions on stream bufferzones,alluvial valley floors, and water rights are <br />also included. <br />Ground Water Protection <br />The discussion for ground water protection has been divided into three parts: 1) ground water <br />quality; 2) ground water quantity; and 3) ground water monitoring. <br />Ground Water Quality <br />Mining practices that involve replacement of spoil material into mine pits are detailed in Section <br />2.05.4(2)(c), Backfilling and Grading. Topsoil and overburden handling procedures are detailed in <br />Section 2.05.4(2)(d), Topsoil (Redistribution). These handling procedures were developed after <br />reviewing the physical and chemical properties ofthe overburden, coal, and interburden in the New <br />(REVISED 6/01) 2.05.6(3) - 2 <br />
