III. Prediction of probable hydrologic consequences of the mining operation.

A. Prediction of mining impacts (surface water):
   1.Provide rationale for selection of the hydrologic technique that allows for prediction of the 
     potential impact based on overburden, mining methods, hydrologic concerns, and              
  reclamation plans.  The following are some examples:
     a.Erosion changes (MUSLE, RUSLE, etc.)
     b.Runoff changes (SCS, HEC-1, Rational Equation)
     c.Chemical quality impacts (empirical relationships to overburden, mixinge quations that    
     will handle alkaline-acid buffering, etc.)
     d.Disruption or elimination of aquifers by removal of the coal resource.

   2.Assess impacts to receiving streams and water users.

B. Prediction of mining impacts (ground water):
   1.Select hydrologic techniques that allow for prediction of potential impacts based on           
  chemical analysis of overburden, mining methods, hydrology and reclamation plans.  The      
following are some possible examples:
     a.Loss or gain of ground water by prediction and analysis of water level changes in            
   unconfined aquifers.
     b.Changes in aquifer characteristics.
     c.Chemical change of ground water by solute transport analysis, correlation with
overburden        chemistry, etc.
     d.Disruption or elimination of aquifers by removal of the coal resource.
    
   2.Assess ground-water impacts on receiving streams, regional aquifers, and local water         
  users.

C. Make predictions of mining impacts on stream morphology:
   1.Changes in stream stability.
   2.Upland stability problems.
   3.Impact on land use, water uses, etc.
   4.Effect of permanent structures (ponds, diversions, etc.) n stream morphology.
