LANSING, MICH. The Michigan Department of Environmental Quality (MDEQ), Water Resources Division, has issued Enbridge a permit to install 48 anchor support structures into the lake bed on Line 5 pipelines to decrease the span distance at these locations within the Straits of Mackinac. The project is located in Wawatam Township, Emmet County and Moran Township, Mackinac County, Michigan. MiWaters permit number WRP014208 v.1.
The MDEQ completed its review and drafted the permit on November 5, 2018, under authority of Part 325, Great Lakes Submerged Lands, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended. Enbridge returned the permit on Friday November 30, 2018.
Project activities involve the installation of a helical anchoring system with saddle mounts around the pipeline in each of the proposed locations. The 48 anchors will be augured directly into the lake bed using 10-inch diameter screws. The total direct lake bottom impact of all screw augers will be approximately 20 cubic yards with a total footprint of about 53 square feet. Permit conditions require verification of anchor support placement by diver or remote operate vehicle including documentation of pipeline coating conditions after anchors are installed.
The 48 proposed anchors are for the purpose of minimizing the potential of having any pipe spans exceeding 75 feet. This work is being completed to fulfill Enbridge’s obligations under the State of Michigan 1953 bottomlands easement between Enbridge and the Michigan Department of Natural Resources, as well as the Enbridge-U.S. Environmental Protection Agency Federal Consent Decree. This project is not associated with any new utility installation.
