The following <br />points were brought out at the meeting and are worthy of note: <br />Soils within the study area will be mapped and sampled with areas <br />proposed for potential surface disturbance mapped and sampled in <br />greater detail. Each major soil will be described, sampled and <br />tested. Soils will be classified to the series le:~el. Qualitative <br />and quantitative evaluations of the suitabilit/ of the soils for <br />reclamation will be made. <br />Using the land use categories in the t1LRD regulations at 1.04.71 <br />specific land use information will be gatherer and analyzed for the <br />study area. 1-0h en appropriate,recent (five years or less) changes <br />in land use will be documented. <br />Analysis of roof and floor material will follcw the regulations and <br />all pertinent guidelines from t1LRD. Cores frcm seven holes will <br />be used, resulting in approximately one hole per se~:tion. P1ean <br />and standard deviation values will be calculat.ad. `lalues will be <br />compared against water quality standards with :he implications of <br />amomalous values discussed.' <br />For potential shaft locations surface to total dep':Ir overburden <br />analysis will be obtained using composite sainp,es r:'. available core <br />representative of the strata to be encountered T}I~se cores are <br />available from the ten holes drilled and will +~.llow accurate repre- <br />sentation of the total overburden column. <br />Areas for discussion for ground water hydroloc~ were the lJadge <br />coal seam aquifer, the Twentymile sandstone and the alluvial aqui- <br />fers and their relationship to the shallow ground water system. <br />4later quality of mine inflows, if any, mine discharges to surface <br />waters and the possible effect of these discharges will require <br />Gulf <br />• we~~ou w+ os au ~~ oa coeaownnow <br />vi...,,n..
