IMPACTED SEDIMENT DREDGING
PROJECT SUMMARY
BCC was engaged by NRG Energy, Inc. (NRG) to remove potentially impacted sediments from the Waukegan Station’s Lakeside Cooling System Outlet and 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 to not disturb the Great Lakes Piping Plover nesting around 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.
The scope of work included:
-
Dredging 50,000 CY from the Lake Side
-
Dredging 15,000 CY from the Intake Canal
-
Utilization of biodegradable hydraulic oils in excavators
