<br />-z- <br />While the Division would, of course, consider a demonstration <br />that involved a drilling program through the tailings facility <br />(and collect:ion pond) as you have mentioned, the Division prefers <br />leaving the liners intact as much as possible. Consequently, <br />discussions with the operator on July 2, 1993, also included the <br />possible drilling of angled holes from beyond the margins of the <br />facility (and presumably the pond) to a representative number of <br />points beneath these structures to secure the direct evidence of <br />water quality that the Division agrees is required. <br />In conclusion, because the Division will require direct evidence <br />of the absence of a contaminant plume below the tailings facility <br />and collection pond before allowing the operator to terminate the <br />ground water monitoring program and secure release of hie <br />reclamation responsibility, the Division does not feel it <br />necessary to require the ground water monitoring network be <br />maintained for any specified number of years. <br />If you have any further questions, feel free to contaot me. <br />Sincerely, <br />~y[~J~ GSA <br />/games C.
