St. Marys River Sea Lamprey Traps, Chippewa County, Michigan

Posted: 12/20/2016

Expiration date:


The U.S. Army, Corps of Engineers (USACE), Detroit District, has completed an Integrated Detailed Project Report and Environmental Assessment (IDPR/EA) addressing the construction of two permanent sea lamprey traps at Gate 16 of the Federal Compensating Works  at Sault Ste. Marie, Michigan to replace the temporary sea lamprey traps.  The IDPR/EA may be reviewed on line at the following web address: http://www.lre.usace.army.mil.  Go to the category "Other Public Notices" in the lower left corner of the webpage.  A paper copy of the IDPR/EA may be reviewed during normal business hours at the reference desks of both the Bayliss Public Library, 541 Library Drive, Sault Ste. Marie, MI 49783 (telephone number: (906) 632-9331) and the Lake Superior State University, Kenneth J. Shouldice Library, 906 Ryan Avenue, Sault Ste. Marie, MI 49783 (telephone number: (906) 635-2815).  A paper copy is also available for review at the U.S. Post Office located at 161 Ridge Street, Sault Ste.
Marie, MI 49783.  A paper copy may be obtained by writing to the USAGE address identified below.

The proposed action for this project involves the placement of steel piles into the river bed immediately downstream of the Gate 16 Compensating Works concrete spillway
apron to hold the traps, pouring of a concrete pad on the river bed to set the traps on, construction of an overhead walkway set on the steel piles, placement of a davit to lift the traps and the construction of a concrete pad on the uplands to set the traps on for sea lamprey removal.  Replacement of the temporary traps with permanent traps will provide for the removal of additional spawning phase adult sea lamprey.

Environmental review of the proposed action indicates that no significant cumulative or long-term adverse environmental impacts would be expected as a result of project implementation.  The identified adverse effects would be minor, including short-term noise and air emissions from equipment operation; temporary, non-adverse turbidity from construction operations; temporary displacement of fish; and destruction of bottom­ dwelling organisms within the concrete pad placement area. Fish would return upon completion of construction.

The IDPR/EA includes a Section 404(b)(1) Evaluation, pursuant to the Clean Water Act, for placement of fill material into the waters of the United States.  Any person who has an interest that may be affected by the discharge and/or disposal of fill material may request a public hearing.  To be considered, the request must be submitted in writing to the contact provided below or to the following email address: "St.Marys.River.SLT@usace.army.mil"  within the comment period of this notice and must clearly set forth the interest that may be affected and the manner in which the interest may be affected by this activity.  Any comments you may have concerning the proposed project should be made within thirty (30) days from the date of this notice.  If no comments are received by the end of the thirty (30) day review period, it will be assumed that you have no comment.  Please direct your comments to:

U.S. Army Engineer District, Detroit ATTN: CELRE-PLE (Charles A. Uhlarik)

The proposed project cannot be constructed unless a State of Michigan water quality certification is issued or waived pursuant to Section 401 of the Clean Water Act.  The proposed project's non-federal sponsor will obtain the required permits prior to construction.

Copies of this Public Notice and IDPR/EA are being sent to the U.S. Environmental Protection Agency, U.S. Fish and Wildlife Service, the State of Michigan and other Federal, tribes, state, local agencies, interested groups, and individuals.  Following the 30 day comment period and a review of the comments received by the USACE, the District Engineer (Detroit District, USACE) will make a final decision regarding the necessity of preparing an Environmental Impact Statement (EIS) for the proposed project.  Based on the conclusions of the IDPR/EA, it appears that preparation of an EIS will not be required; therefore, a preliminary Finding of No Significant Impact has been included in the IDPR/EA.
