West Fork Unit

West Fork Unit Tailings Embankment Design and Permitting

Prior to joining Tierra Group, our Team was the Design Team Leader/Project Manager for designing a 20-foot downstream cycloned tailings embankment raise, and an earthen-cut emergency spillway.  A design report and and operating protocols were prepared and submitted to the State of Missouri Department of Dam Safety and the Team acted as the Lead Technical Advisor during State dam inspections. Our Team developed a long-term tailings impoundment management plan, which led to obtaining a State of Missouri five-year operating permit. We also Renewed National Pollution Discharge Elimination System permits for the impoundment, provided recommendations for tailings spigoting patterns and schedules, impoundment water discharges; embankment design, slope stability, and construction schedule.
