D. A. Berry - 6 - August 29, 1996 monitored to provide baseline data which is undisturbed by mine-related activities? Enclosed is revised Map 09 which shows the proposed location of the six alluvial wells for the loadout and refuse pile area. Also enclosed is a drawing titled Alluvial Wells - Typical Completion Diagram. The completion diagram is to be inserted into Volume III, Exhibit 3. BRL should be able to have the six alluvial wells installed by the 4th quarter of 1996. Realistically, no coal or refuse will be handled until the second quarter of 1997. Therefore, BRL will at a minimum, develop three quarters of baseline monitoring data. vi. ) DMG - The Rol.l.ins sandstone well DH-34b i.s not ideal. ].y situated to detect mine-related impact; however, monitoring of this single Rollins wel.L wi].i. be sufficient until such time as BItL intends to permit m.irri.ng i.n the B-2 coal seam, or if other mining proposals are made. Based upon infol-mation provided by BRL, it appears that. typical Ro1li.ns water p].ezorru=_tr.ie surface projections are several hundred feet below the D-2 seam currently proposed for. mi.niny. Moni.tor.i.ng as proposed faith this application is acceptable. However, the B-2 seam may be wi.thi.n the artesion •rone emanating from the Rollins sandstone, and communication with future B-2 seam +forkings through faults could be possi.bl.e. Additional consideration will be given to further Rollins sandstone monii.ori.ng, both baseline and operational, i.f and when B-2 seam mining is proposed. BRL agrees that impacts to water in the Rollins Sandstone due to mining in the D-2 seam will be nonexistent. There are no formal plans to mine the B-2 seam at this time. vii) The complet.i.on drawings for wells DH-54 and DH-55 state that a portion of the casing is slotted while the reroair~ing portion i.s solid. However, the stippling in the drawings show that the entire casing is slatted. Please x~econc.ile the d.iff.erence, and revise the submittals as need. Completion diagrams for wells DH-54 and DH-55 where revised to show the "stippling" correctly. Enclosed are revised completion drawings DH-54 and DH-55. The completion diagrams are to be inserted into Volume III, Exhibit 3.
