PROJECT SUMMARY

BCM Remediation (BCM) was engaged by NRG Energy, Inc. (NRG) to remove potentially impacted sediments from the stations Lakeside Cooling System Outlet and Cooling Intake Canal, 50,000 cubic yards of sediment were dredged from the Lakeside Cooling System Outlet and 15,000 cubic yards of sediment were dredged from the Cooling Intake Canal.  This activity was conducted in the middle of the winter in Lake Michigan. The dredging had to be conducted between December and March as to not disturb the Great Lakes Piping Plover nesting in the area of the power plant.  CAT 349 Excavators were modified to allow operation in extreme weather conditions. Temporary access roads were constructed into Lake Michigan to allow dredging to a depth of 12 foot.  The dredged sediment was transported to an on-site material management facility.
