Under <br /> the Climax Mine Environmental Protection Plan, a final additional measure has been <br /> considered and designed. <br /> The 4-Dam Seepwater Return System is an Environmental Protection Facility in the <br /> Eagle River Basin at the toe of 4-Dam. While Climax expects that tailing removal and <br /> flushing of the foundation materials will occur over a period of several years, temporary <br /> management of these waters is needed. Until water quality at the toe of 4-Dam meets <br /> standards for the receiving stream, pumping of the containment system at the dam toe <br /> will be provided to Robinson Reservoir. The attached dialog and design sheets are <br /> herein submitted to the Division for review and acceptance as an Environmental <br /> Protection Facility modification. <br /> Climax would appreciate your review and input in as short a time frame as possible. I <br /> would be happy to discuss details and considerations made in this modification to <br /> facilitate your understanding of the protection measures it affords. <br /> Sincerely, <br /> Bryce R. Romig <br /> Environmental Coordinator <br /> Climax Mine <br />
