<br />Response E <br /> <br />The lowest Menefee formation coal seam, the A Seam, contains <br />a bottom component of extremely dense and exceptionally hard <br />material. This component acts as a virtually impermeable seal. <br />Where the bottom component is exposed on the surface, adjacent to <br />the portal, this material is neither readily rippable nor <br />permeable to surface water. This "seal" bed will obviously act <br />as an impermeable membrane for any water entering the mine where <br />ponding will occur. As water accumulates down dip, it will be <br />pumped out of the mine and routed to the water impoundment area <br />for treatment. <br />This dense bed will also protect the Point Lookout sandstone <br />from potential "rubblization" associated with mining. This <br />natural buffer will not be penetrated during the mining process <br />because it is not coal material. <br />The Messier well is estimated to be collared at <br />approximately 7,400 feet in elevation in the Cliff House <br />sandstone. The Messier well is 360 feet deep to a depth of 7,040 <br />feet in elevation. This well is situated on the northwest flank <br />of the Perins Peak syncline. This puts the bottom of the well <br />(7040') above the mine portal (7,000') and the coal seam (6880'). <br />Additionally, all mining will occur below the portal elevation <br />(7,000'). Finally, the ground water flow is projected to be ~ <br />southeasterly toward the syncline's axis. Considering these <br />conditions, the probability of impacting the water quality of the <br />Messier well is impossible. <br />
