Response to Office of Mined Land Reclamation Request Dated March 25. 1996 for Additional Information Re ag rding Drain Cover Fill. Dear Mr. Keffelew: The Cripple Creek & Victor Gold Mining Company "CC&V") appreciates your efforts to resolve the remaining questions regarding the thickness of the Drain Cover Fill proposed by CC&V on January 9, 1996. This proposal was further addressed in CC&V's letter of March 4, ]996, which responded to the Office of Mined Land Reclamation's ("OMLR") initial review of the Technical Revision. As you know, we received the referenced letter dated March 25, 1995 by facsimile on April 2, 1996 and appreciate your expediting its transmission. On April 5, 1996, when CC&V received the original letter, it was found that page 2 of that letter had not been transmitted by facsimile. CC&V has been working diligently to understand the OMLR's remaining concerns and to identify information that will convey an appropriate level of comfort to the OMLR to resolve this last remaining item associated with the January 9th proposal. The information received from the OMLR by CC&V on April 5, 1996 reflects in-depth review by the OMLR. CC&V appreciates your narrowing of the issues to that of the Drain Cover Fill thickness. We are, as you know, concerned that there still is some uncertainty in the minds of the OMLR reviewers as to the suitability of the CC&V proposal for the thickness and placement procedures for the Drain Cover Fill. Therefore we have worked to provide information and procedures that will satisfy these concerns. CC&V reads your letter as identifying three areas in need of further information from CC&V. These are (1) the occurrence and effects of freezing and thawing on the Soil Liner Fill, (2) the location, with respect to the liner, of the drainage pipes embedded in the Drain Cover Fill, and (3) the method of placement of the Drain Cover Fill. CC&V addresses these three items in this response. If we have omitted any other items, please let me know immediately.
