<br />The 350 feet thick Cliff House is a grey marine sandstone interbedded with <br />shale. The sandstones are typically lenticular, but may be locally massive, <br />while the shales are generally barren of coal. <br />The floor of Coal Gulch is covered by a thin veneer of surficial <br />colluvial/alluvial debris. Small slope failures are quite common on the sides <br />of the Gulch. Springs from these rotational slides may be locally important <br />by contributing flow to Coal Gulch during the spring and early summer. <br />The proposed operation is in compliance with the requirements of this section. <br />V. Ground Water Hydrology - Rules 2.04.5, 2.04.7, 2.05.6 (3) and 4.05 <br />Ground water hydrology information may be found in the Permit Application in <br />Sections 2.04 and 4.05. Additional information is available in the PAR <br />response. <br />The applicant states that there is very limited ground water occurrence in the <br />Coal Gulch area. This is based on old mine maps and records which indicate <br />little water was ever pumped from the workings. The applicant also states <br />that local recharge must be up dip of the present mine site, and that ground <br />water flow is parallel with and dependent upon dip direction. <br />Based upon observations by the Division, there is groundwater flow in this <br />area. This is substantiated by abandoned portal discharges observed both by <br />the applicant and by the Division. Ground water in this area is found in a <br />semi-confirmed state, and the direction of flow is dependent on dip direction <br />and on topography. <br />Map 7 (Geology/Hydrology), in tfie permit application, indicates that the <br />Perine Peak Syncline bisects the southeastern corner of the permit area. This <br />syncline could control local ground water flow conditions to some degree. <br />The following ground water systems exist in the permit and adjacent areas: <br />1) Lightner Creek alluvial aquifer; <br />2) discontinuous colluvial flow systems <br />tributaries; <br />3) localized subsidence related systems; <br />4) minor coal seam aquifers; <br />5) perched aquifers within the Menefee, <br />6) Regional aquifers of the Cliff House <br />Sandstone/lower Menefee Formation. <br />in Coal Gulch, and it's <br />above and below the 'A' seam. <br />Sandstone and Point Lookout <br />
