More Work at Upper Reservoir

Ameren has notified FERC that the consultants retained by Ameren's property insurer, Rimkus Consulting Group, were drilling borings near the Upper Reservoir. The original plan was to drill three core samples to a depth of 75 feet. However, after the first boring, the plan was changed to seven borings to a depth of 30 feet. This work is being done as part of the geotechnical invistigation for a possible rebuild of the Upper Reservoir.
