Closure of the Grey Eagle Mine tailings impoundment is an example of closing a "wet" tailings impoundment at the cessation of milling operations. This paper presents a summary of tailings cover design and construction, tailings deposition sequences to facilitate closure, construction schedules, costs, and post-closure monitoring. Permit requirements which influenced the design and construction of the tailings are summarized. The performance of the cover and post-closure monitoring issues are also discussed.
