  • Fall Protection Around The MacArthur and Poe Locks, Bridge Anchor Points for Temporary Bridges Across MacArthur and Poe Locks and Handrails Around the MacArthur Lock Gates, St Marys Falls Canal (Soo Locks), Sault Ste Marie, MI

    Expiration date: 5/5/2023

    TO: All INTERESTED AGENCIES, PUBLIC GROUPS, AND CITIZENS The U.S. Army Corps of Engineers (USACE), Detroit District, is proposing work at St. Marys Falls Canal (Soo Locks, Sault Ste. Marie, Michigan). The work includes the following: adding additional fall protection at the MacArthur and Poe Lock chambers, installing bridge anchoring points at the MacArthur and Poe Lock chambers, and MacArthur Lock handrails replacement (Enclosure 1). This project constitutes an “undertaking” under Section 106 of the NHPA. This notice is provided pursuant to Section 800.6 of 36 C.F.R Part 800, Protection of Historic Properties, and Section 106 of the National Historic Preservation Act (NHPA), 54 U.S.C. § 300101 et seq. A copy of this public notice can be provided upon request or can be reviewed online at by clicking on the link to “Other Public Notice” in the bottom left corner. Fall Protection for Soo and MacArthur Locks Chambers: During the navigation season, for any maintenance or inspection activities that require approaching lock chamber walls, the USACE personnel are required to wear safety harnesses, secured to mooring points to reduce the fall risk, per an Occupational Safety and Health Administration (OSHA) requirement (OHSA 1917.112(b)(1) which requires a guard rail at least 43 inches in height near an opening. Line handlers cannot use safety harnesses during mooring activities, as it poses a risk of entanglement with the mooring lines. During the winter maintenance season, the USACE utilizes temporary plastic barriers around dewatered locks to reduce the fall risk. The USACE has determined that additional safety measures, such as guard rails or concrete walls, are needed along the MacArthur and Poe Locks to meet current OSHA standards. Additional safety measures would help reduce the risk of a person falling into an empty or filled lock chamber, or a person being crushed between a vessel and a lock wall (the railing/wall will also reduce or eliminate the risk of drowning).
  • The Demolition of Existing Storage Buildings and Construction of New Storage Building at the St. Mary's Falls Canal (Soo Locks), Sault Ste. Marie, Michigan

    Expiration date: 3/21/2023

    The USACE is proposing the demolition of existing storage buildings and construction of New Storage Buildings at the St. Mary Falls Canal (Soo Locks), Sault Ste. Marie, Michigan. The Soo Locks is listed on the National Register of Historic Properties (NRHP) and National Historic Landmark (NHL). One of the buildings proposed to be demolished West Wing which is a contributing element to the National Historical Landmark. The USACE has determined that the demolition of a contributing building would have an "adverse effect" to the historic nature of the Soo Locks under Section 106 of the National Historic Protection Act. The USACE will be developing a Memorandum of Agreement (MOA) to address these adverse effects which will include recordation of the contributing structures before demolition and the presence of archeological and tribal monitors during ground disturbing work.
  • Finding of “no adverse effect” under Section 106 of the National Historic Preservation Act (NHPA) for proposed Duluth Ship Canal Protection project.

    Expiration date: 4/7/2023

    The USACE is seeking to complete the protection of public paths along the shoreline and public park grounds that are adjacent to the Duluth Ship Canal’s North Pier and Lake Superior Maritime Visitor Center by constructing a T-Wall and armor stone revetment on USACE property. In addition, the proposed project will also include the installation of two storm drain substructures that will require re-grading and replacement of concrete within the park grounds adjacent to the Duluth Ship Canal’s North Pier and Lake Superior Maritime Visitor Center. Aesthetic improvements of the public park grounds will also be done as part of the proposed project.
