• ground rater aquifer. A detailed discussion of the influence of <br />solute leaching on ground water quality is presented in response to <br />this Bule under the heading, "Probable Hydrologic Consequences". <br />liethoda of protection and !litigation <br />Leaching rithin the proposed permit area is unavoidable <br />rhenever rater saturates spoil material. Once leaching has <br />occurred, there is no practicable technology currently available to <br />treat the rater to decrease TDS concentrations. The only method to <br />minimize the impacts of mining and leaching on ground eater quality <br />is to minimize the amount of rater which can pass through spoils. <br />To accomplish this, tro types of spoil disposal are proposed in <br />• connection with mining and reclamation activities within the <br />proposed permit area. One is to move spoil into the previous cut or <br />mined areas as mining progresses. The second is to haul and <br />stockpile spoil aray from the pits in temporary overburden <br />stockpiles. The primary means of minimizing rater flow through the <br />spoils will be to regrade, topsoil, and revegetate the mined areas <br />se soon as possible following coal removal. This will have a <br />dramatic effect on minimizing the amount of water entering the <br />spoils. In fact, according to Lusby and Toy (1976), the <br />infiltration rates of reclaimed land are lover than the same land in <br />the premined condition. A detailed discussion of reclamation and <br /> revegetation as related to hydrology has been presented under this <br />• Bule under the heading " Surface Water Quality protection". <br />2.05 - 156 <br />
