REVIEW QUESTION <br />• (1)(b)(i)(a) Please give specific locations on a map arrd on cross-sections <br />which show where .subsurface water zones are encountered. <br />RESPONSE <br />~ The H-G Coal Company proposes to illustrate the specific loca- <br />tions of subsurface water zones utilizing the extensive explora- <br />tion drilling program data. Geophysical (resistivity) and dril- <br />lers log data will be used to locate and map water producing <br />zones along with bore hole water levels. This data will be pre- <br />sented in the form of a depth water level encountered in the <br />overburden. During developmental and exploratory drilling, most <br />of the holes revealed dry overburden. Any bodies of water con- <br />tained in the overburden will be lenticular, extremely localized <br />in extent and probably perched above the coal aquifer. Rela- <br />• ' tively dry overburden and localized, lenticular water bearing <br />strata are characteristic of coal sequences throughout the <br />west. At the H-G Mine, these factors are attributable to: <br />o Limited recharge lateral extent (outcrops) <br />o Limited precipitation <br />o Lack of suitable aquifer material in the overburden <br />o The vertical movement of precipitation recharge to the coal <br />aquifers <br />Overburden water level map may be found in the ground water re- <br />port. !1 <br />~\~~ - <br /> <br /> <br />
