Enbridge signed an agreement with the state in 2018 to build a $500 million tunnel to house Line 5 after months and years of concern from environmental groups concerned about the impact of a strait spill on the Great Lakes. A tunnel on the 5 Straits of Mackinac line would be state-of-the-art, with improved safety features that reflect our commitment to protecting Michigan`s natural resources. Business-to-business companies have built more than 400 low-pressure tunnels, many with conditions similar to those in Mackinac Strait, according to Enbridge. Enbridge began last year to maintain contracts for tunnel planning and construction and put interested parties on the street so they could understand the width of the project, said Amber Pastoor, project manager for the Great Lakes Tunnel project. “If we move forward now, we are getting closer to the finish line,” Nystrom said of the proposed tunnel that would place the pipeline in a tunnel into a rock. Enbridge has been and will continue preliminary work for the Straits of Mackinac tunnel project, while time permits, has just been allowed to install 54 poles for the existing building, and is asking a Lansing judge to dismiss Attorney General Dana Nessel`s case against the company. The state authority responsible for managing the Enbridge tunnel project will hold its first meeting in 15 months on Friday in St. Ignatius. Enbridge completed geotechnical drilling on the street this summer to prepare for the construction of the tunnel with government approvals it obtained before Whitmer halted state work on the pipeline in March. The body`s Friday permits will allow the company to install poles on exposed sections of the pipeline this week and bring back an un assisted 81-foot fork, in keeping with its state relief.
The tunnel is the best solution to the concerns expressed in Michigan and Enbridge plans to continue to advance with about $40 million in geotechnical work at the site, Duffy said. The company ensures the security of the existing line. On December 19, 2018, Enbridge announced that it had reached an agreement with the Mackinac Straits Corridor Authority (MSCA) regarding the future of Line 5 of the Line 5 Light Oil and Natural Gas (NGL) pipeline on Mackinac Strait. In March, Nessel declared the lame duck of the legislature unconstitutional to create a framework and governmental power over the tunnel. And when the governor was unable to convince Enbridge to agree to a two-year period for the construction of the tunnel, the company asked a judge to oppose Nessel`s opinion and consider the tunnel agreement to be valid and applicable.
