PUBLIC NOTICE - REQUEST FOR PERMISSION TO MODIFY A U.S. ARMY CORPS OF ENGINEERS PROJECT UNDER SECTION 408

Public Notice/Application Number: MC-15-01

REQUESTER 

Metropolitan Water Reclamation District of Greater Chicago

111 East Erie Street, Chicago, IL 60611

Proposed Action

The proposed action is an alteration to the Federal Chicagoland Underflow Project (CUP) McCook Reservoir Project that includes the construction of a new 20-foot diameter tunnel from the Des Plaines 33-foot diameter Tunnel and Reservoir Plan (TARP) tunnel southern terminus straight to the reservoir.  An outlet structure would be constructed at the terminus of the new tunnel in the reservoir.  The new tunnel would be 5,350 feet long and would include isolation gates.  The direct tunnel connection between the Des Plaines TARP Tunnel and the McCook Reservoir would allow for gravity flow into the reservoir under a full range of operating conditions.  The gates would regulate up to 11,000 cfs of flow from the Des Plaines TARP tunnel into the reservoir.  The authorized storage allocation for the Des Plaines TARP Tunnel system of 2000 acre-feet will not change with this modification.  (See drawings in the attachment).  A detailed description of this proposal is provided on page 2 of the attachment.
