INTRODUCTION - TECHNICAL REVISION BASIS The 1989 Amendment to the Climax Mine MLRD Permit No . 77-493 designated the N, . 4 Dam Reservoir (M(j- lly-Oxide Tailing Pond ) as a permanent Water titorage Site that ''would require little or no grading'' in order to satisfy flnai reclamation requirements . ine amendment did not specify a final reclamation comp l et. + on date at the time of submittal , and it was impi led that final reclamation was to be coincidental with or subsequent to the end-of- life of the Climax Mine . Because of market conditions and the resultant revision of the estimated ore reserves , downsizing, of the Climax Mine became an economic necessity . This was the underlying reason for the submissioi-, of the 1989 MLRD Permit amendment which was approved by the Colorado Mined Land Reclamation Board . Many of the production and water nanaIing facilities are no longer needed to support future projected molybdenum product : on rates . As a result , it became feasible to accelerate the final reclamation schedule for some areas . The former Molly-Oxide Tailing Pond was one such facility since it had a potential possible alternative use as a fresh water storage facility . The Climax Mine made the decision to accelerate the conversion of the former Moly-Oxide Pond into the Eagle Park Reservoir , and a joint MLRD/Climax discussion , relative to the project , was conducted on February 18 , 1993 . The initial decision of the Division was that a Technical Revision to the Permit would not be required , however after further evaluation , the Division has subsequently decided that a Technical Revision to the Amended Permit would oe in order . In view of the scope of the proposed project , and since the 1989 Amendment was not definitive in specifying the type of water storage , nor the conversion details involved , the Climax Mine concurs with the Division , and herein proposes a Technical Revision .
