Enbridge has submitted to the Michigan Circuit Court and to the State of Michigan the results of inspections of the area of interest on the west segment of Line 5. The inspection, using an inline inspection tool, found no internal or external metal loss or dents. This test reconfirms that the west leg of the pipeline is safe to operate.
Enbridge has continued to work with both the Pipeline and Hazardous Materials Safety Administration and the State of Michigan about both the west and east segment investigations and will continue to do so. Enbridge hopes to have the east segment operational again soon.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) together with the Michigan Public Service Commission (MPSC) and Michigan Department of Transportation’s (MDOT) Mackinac Straits Corridor Authority (MSCA) recently announced the launch of the
Line 5 in Michigan website
. The new multi-agency website –
– is designed to keep the public informed about Enbridge Energy’s proposal to relocate the current section of the Line 5 oil and natural gas liquids pipeline that crosses the Straits of Mackinac with a new section of pipeline to be housed in a tunnel beneath the lakebed.
In addition to providing an overview of the regulatory permitting process that the proposed project must follow, the website will also include technical and permitting documents, timelines, maps and other resources to help the public better understand the tunnel proposal and the unique roles various state entities play in the permitting process.
Under Michigan law, EGLE is the regulatory agency responsible for environmental permitting for the tunnel project, while the MPSC has siting authority for pipelines that carry crude oil and petroleum products. Housed within MDOT, the MSCA is responsible for overseeing construction and operation of the proposed tunnel. MSCA would own the tunnel after its construction and provide independent oversight throughout its life.
Finally, the Michigan Department of Natural Resources released numerous Enbridge Inc. documents related to the company’s easement compliance for its operations in the Mackinac Straits. In June 2019, Michigan Governor Gretchen Whitmer tasked the Michigan Department of Natural Resources (DNR) with undertaking a comprehensive review of Enbridge compliance with a 1953 easement for the company’s dual petroleum pipelines at the straits. The easement outlines the terms under which Enbridge can operate the pipelines on the bottomlands of the Great Lakes.
The DNR has requested and received from Enbridge numerous documents necessary to complete this review. The documents supplied by Enbridge are now
for public review.
IPGA will continue to monitor the Line 5 issue in Michigan and provide its members with updates relevant to the Indiana Propane industry.
