In another united showing of support for the integral Line 5 pipeline, operated by Enbridge, and plans to build the Great Lakes Tunnel, the PA Chamber of Business and Industry joined with the U.S. Chamber of Commerce, the Canadian Chamber of Commerce, the Michigan Chamber of Commerce, the Ohio Chamber of Commerce and the Wisconsin Manufacturers & Commerce in filing a joint amicus brief in federal court. The brief is in response to Michigan Gov. Gretchen Whitmer’s stance on trying to shut down the key pipeline.

Line 5 delivers 540,000 barrels per day of oil and natural gas liquids to heat homes and fuel vehicles in parts of the Great Lakes region, including southwestern PA. Line 5 also supplies the refineries that produce aviation fuel to Pittsburgh International Airport.

The shutdown would result in energy shortages and even higher prices for home heating fuels like natural gas and propane. It would also result in the loss of tens of thousands of jobs and jeopardize billions of dollars in economic activity.

In its brief, the Chambers noted that Russian-Ukraine conflict has added renewed importance on energy security and expedient legal resolution to ensure safe, reliable, and affordable access to multiple energy sources, including the pipeline.
