Addendum to Environmental Assessment
Addendum to the U.S. Army Corps of Engineers Environmental Assessment Entitled:
EMERGENCY MEASURES ASSOCIATED WITH THE MAINTENANCE OF THE CSSC FISH DISPERSAL BARRIERS
Purpose and Need: The purpose of this Addendum is to clarify actions that will be taken to prevent Asian carps from becoming established in the Great Lakes via the Cal-Sag Channel (CSC), Cook County, Illinois. These activities will be conducted using funding in Fiscal Year 2010 through appropriations to the Environmental Protection Agency under the Great Lakes Restoration Initiative (GLRI) and transferred to the U.S. Fish and Wildlife Service (FWS). FWS distributed funds ultimately to the State of Illinois to support efforts to control aquatic invasive species including Asian carps. Actions previously funded to support this goal were provided by the U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, and U.S. Fish and Wildlife Service's Office of Federal Assistance. Actions covered by those operations included: 1) conducting monitoring and assessment in the Chicago Sanitary and Ship Canal, and 2) applying rotenone, during December 1-9, 2009, to eradicate fishes in the 5.5-mile area Chicago Sanitary and Ship Canal (from above the electrical barrier system to Lockport Lock and Dam).
