Curt Sealy and myself today to discuss the <br /> cleanup activity of the PCS at the D-2 Mine. Enclosed are the results of the verification <br /> sampling that we discussed during the meeting. <br /> Based on the discussion, Umetco will construct a monitoring well down gradient and in <br /> close proximity of the PCS site. If water is intersected within 75 ft. of the surface <br /> elevation, Umetco will monitor the well on a quarterly basis for a period of one year for <br /> TEPH, TDS, and pH. The pit created by the excavation of the PCS will remain open <br /> until the results of the monitoring well program are reviewed by your department. <br /> If you have any questions, or need more information, please call. <br /> Sincerely, <br /> Tony Bates <br /> Mines Reclamation Manager <br /> Enclosure <br /> cc: W. Erickson. DMG <br /> L. Deremo <br />
