Madison, Wis – As part of yesterday’s contested case hearing pertaining to the Line 5 Relocation Project, staff from the Wisconsin Department of Natural Resources – who spent more than four years reviewing the proposed Line 5 Relocation Project – reaffirmed the project would have no impacts on peak flow from stormwater runoff.
Christopher Linskens, Wisconsin DNR Regional Stormwater Engineer, stated, “…in my experience with the peak flow modeling and site design made it fairly obvious to me that there would be no peak flow impacts or significantly measurable impacts. When looking at the flow rate versus the volume model, there would be a lower impact because of the decrease in CFS from 200.9 in the existing condition peak flow model and an after restoration peak flow to 200.6 CFS post construction based on the model.”
The contest case hearing continues through October 3, with Enbridge and Wisconsin Department of Natural Resources experts testifying on the project this week.
The hearing is a result of opponents of the project initiating the “contested case” process challenging the permits issued by the Wisconsin DNR for the Line 5 relocation project. The challenge comes even though the DNR spent more than four years compiling and analyzing data, held multiple public hearings and comment periods, and relied on the most state-of-the-art modeling available to make their decision. A nearly 900-page DNR environmental impact statement scientifically and legally justified the issuance of project permits. The DNR also included 231 conditions on the permits to require the strongest environmental standards possible.
Line 5 is unique because it not only moves crude oil that is refined into transportation fuels, but it also transports natural gas liquids that are made into propane. In fact, a public comment submitted to the DNR by major propane supplier Plains Midstream sent a critical warning that a rejection of the Line 5 relocation project would likely send Wisconsin into a propane state of emergency, leading to supply shortages and massive price increases.
During the Wisconsin DNR’s permitting process, over two dozen of Wisconsin’s leading organizations representing farmers, small businesses, labor unions and papermakers submitted comments in favor of the relocation project. Those groups included the Wisconsin Corn Growers Association, Wisconsin Propane Gas Association, Wisconsin Building Trades Council, Wisconsin Counties Association, Wisconsin Electric Cooperative Association, Wisconsin Farm Bureau Federation, Wisconsin Independent Businesses, Wisconsin Industrial Energy Group, Wisconsin Laborers’ District Council, Wisconsin Manufacturers and Commerce, Wisconsin Paper Council, Wisconsin Petroleum Marketers & Convenience Store Association, Wisconsin Pipe Trades, Wisconsin Restaurant Association, Wisconsin Soybean Association, Cooperative Network, Dairy Business Association, Great Lakes Timber Professionals Association, Building Trades Council of South Central Wisconsin, Construction Business Group, International Union of Operating Engineers Local 139, Midwest Food Products Association, North Central States Regional Council of Carpenters, Northern Wisconsin Building and Construction Trades Council and Teamsters Local 346. In fact, an analysis of public records found that Wisconsinites supported the Line 5 relocation project by a 2-to-1 margin during the DNR comment period in 2022.
