Water

Abstract

Describe the groundwater flow system(s) that exists within the permit and adjacent area (including areas proposed for auger mining). Include the depth to groundwater, seasonal fluctuations, and the water table conditions present. Describe the relationship of the flow systems to coal seams to be mined. Identify the groundwater movement of the area and the conditions that control and influence the movement and infiltration. Include the influence of any underground or surface mines. Description should include identification of any aquifer above the lowest coal seam to be mined and the first aquifer below the lowest coal seam to be mined. Include stratigraphic units, depths, and any current use. Reference site specific data and other sources used in arriving at conclusions. the impacts of the proposed mining on each water supply within 1,000 feet of the permit application boundary as well as any other water supply which may be affected by mining. Identify each water supply source (or groups of water supplies) that may be contaminated, diminished or interrupted by the mining operation. Describe the probable hydrologic consequences of the proposed mining activities (including auger mining) on the surface and groundwater systems of the permit area and adjacent area both during and after the operation. Consider surface and groundwater hydrogeologic data (including seasonal variations in flow and quality), overburden analysis data, mining (and coal refuse disposal if proposed) and reclamation methods to be employed, existing water uses, effects of previous mining on water quality and quantity, background (baseline) water conditions and other impact factors. If previous mining on adjacent sites has produced acid mine drainage, discuss the relevant factors that would allow this site to be mined successfully. Reference site specific data and other sources used in arriving at conclusions.
