DESERADO MINE. PERMIT NO. C-8t-018 <br />Dear Mr. Mathews: <br />III IIIIIIIIIIIIIIII <br />I am responding to your letters of May 14 and May 24, 1996. Your letters deal with WFU's request <br />to revise subsidence and hydrologic monitoring programs. <br />WFU agrees with Mr. Perxileton's recommendation regarding the subsidence monitoring. We will <br />continue visual inspection above RP-1 twice a year. An aerial photogrammetric subsidence survey <br />will be conducted if an unanticipated significant surtace movement is observed above RP-1, and 'rf <br />directed by DMG. Such survey shall be completed and a subsidence map submitted to DMG within <br />six months of DMG's request, Pages III-24 and III-25 of the permit have been revised to reflect the <br />above commitment. <br />We also agree with your comments regarding the hydrologic monitoring in Lease C-8424 and C-8425 <br />with some amendment. We request that the water sampling be limited Zo ifte middle {Cp81 ftttie Zone) <br />of the watts. Since four of tti8 weps, with the exgeption of WeN 31-7, are scheduled to be mined out, <br />we propose that These wells be oT1Ce again prxx to being mined out. WeN 3t-7 wifl tie <br />sampled prior to bond eet®se. This amendment is being proposed pursuant to my conversation with <br />Barbara Pavlik. Pages II.C-51A and II.C-76 have been revised to accomodate the above <br />amendment. <br />I am enclosing three copies of Pages II.C-51A, II.C-76, III-24 and III-25 for your files. I trust the TR <br />application will be approved in light of the changes agreed to with this letter. Ii you have any <br />questions, please call. <br />Sincerely, <br />r <br />Murari P.
