MEI is supporting AKT Investments with its conditional use permit compliance at Patterson Sand & Gravel Mine for its pit ponds along Bear River. MEI’s roles include developing and implementing a mercury monitoring plan for its use permit, monitoring for a dewatering permit, recommending mercury corrective actions, special study comparing mercury conditions in the adjacent Bear River, and reviewing the site’s Spill Prevention, Control and Countermeasure Plan. A new project with Yolo County will be working with aggregate mining operations along Cache Creek to develop fish mercury control options for their pit ponds.
