Point Lookout Sandstone. This unit outcrops appr•oxirnately <br />.5 toile north of the permit area ire a tributary of Roberts <br />Canyon. A description of the lithe=logic char•acter•istics is <br />given iri this Section Sc.C>4.5) under Ger~er•al Descr•iptiori c.f <br />Geology. The F'~~irit Lookout Sar~dstor~e has an average permea- <br />bility c.f ~. 1 millidarcies ar~d an average pc~r•osity of 1lr;G. <br />The F'c~ir~t Lc~nH.~~i_rt Sandstone is bel~~w the f~~rrnatior~ fr~~rn <br />which coal will be rnir~ed ar~d separated from the coal seam by <br />more than ~ir0 feet of sandstone and shale. Recharge from <br />overlying strata is unlikely because of impermeable shale <br />barriers. <br />• -this is the Drily potential aq~.rifer• below the per•rnit area. <br />Recharge is ~.rp-dip and n~~rth .S t~_ 3 rr.iles along erosional <br />br•eachir~g.
