Enbridge Pipeline Projects in Wisconsin
Enbridge, Inc. and Enbridge Energy Partners (collectively referred to as "Enbridge"), own and operate a liquid petroleum pipeline system that spans approximately 3,200 miles across North America and has been in operation since 1950's. Detailed information on company ownership and structure is included on the company's websites at Enbridge Inc or Enbridge.
The DNR is in the process of preparing a draft environmental impact statement for the Line 5 relocation project. Information on this process, including a recording of a public hearing held on July 1, 2020 and the more than 2,100 written comments received, can be found below, under Environmental Impact Statement.
The US Department of Transportation regulates pipeline safety, construction, inspection, capacity expansion, and maintenance for all liquid petroleum pipelines through the Pipeline and Hazardous Materials Safety Administration (PHMSA). PHMSA is responsible for protecting the public and the environment by ensuring the safe and secure movement of hazardous materials (e.g., crude oil) to consumers by pipeline. PHMSA sets regulations that address safety in the design, construction, testing, operation, maintenance, and emergency response preparedness for crude oil pipelines and related facilities.
Pipeline construction projects often involve federal permits from the US Army Corps of Engineers (USACE) for impacts to waters of the United States, which are separate from the Department of Natural Resources process.
No agency in Wisconsin has authority to determine need for and/or siting of petroleum pipelines.
The Department of Natural Resources regulatory authorities are triggered if construction is proposed through wetlands, across waterways, and for erosion control. Certain construction projects may also trigger air permits. Coordination with the USACE occurs on wetland/waterway permitting. The Department of Natural Resources does not have authority to regulate the amount of material flowing in any pipeline.
Line 5 Relocation Project
Proposed Line 5 Relocation Project
The existing Line 5 pipeline runs from Superior to the upper peninsula of Michigan through the Straits of Mackinac and lower peninsula of Michigan to Canada. Line 5 crosses through approximately 12 miles of the Bad River Reservation of the Bad River Band of Lake Superior Chippewa. Enbridge is proposing a reroute of Line 5 around the Bad River Reservation.
Additional information regarding the segment of Line 5 within the Bad River Reservation, including a lawsuit filed by the Bad River Band, can be found in this brochure created by the Mashkiiziibii Natural Resources Department.
Enbridge is proposing to relocate a 41-mile-long portion of its existing Line 5 pipeline with new 30-inch diameter pipe within Ashland, Bayfield, and Iron County, WI. Enbridge must receive all necessary local, state, and federal permits and/or approvals before construction of the Line 5 relocation project can begin.
The following permits, approvals, and/or reviews are anticipated to be required for the proposed Line 5 Relocation Project:
- Wisconsin Department of Natural Resources (DNR):

Environmental Impact Statement (EIS)
The DNR is preparing an EIS to inform decision-makers and the public about the environmental and socioeconomic effects of the proposed Line 5 relocation and alternatives. The EIS will cover direct local effects, as well as broader impacts at regional, statewide, and larger scales.
The EIS process is outlined in Chapter NR 150, Wis. Adm. Code. This process follows the general steps listed below. Alerts will be posted to this webpage any time there is a public hearing or comment period.
- Public Scoping:
- On June 8, 2020 the DNR issued a public notice announcing a public hearing and comment period on the proposed scope of the EIS, as represented by a draft outline.
- On July 1, 2020, the DNR held a public hearing on the proposed scope of the EIS and on Enbridge's application for a waterway and wetland permit. View the video recording.
- The DNR received over 2,100 written comments between June 8 and July 11, 2020. These comments can be accessed and downloaded here:
Comments from Local and Tribal Governments
Many of the comments received during the public hearing and comment period concerned the status of the pending permit application as "complete" and legal language in the public notice regarding the tentative determination to approve with modifications. This language is further explained in a Public Hearing FAQ.
- Information Gathering, Analysis, and Preparation of a Draft EIS:
- In August 2020 the DNR contracted with TRC Environmental Corporation to prepare a Draft EIS.
- The scope of the EIS analysis was determined based on comments received during Public Scoping and in consultation with tribal governments and federal agencies.
- Subject area experts at TRC and the DNR are gathering information, conducting analyses, and drafting/reviewing portions of the Draft EIS. <we are here
- Draft EIS:
- The DNR will post the Draft EIS on this webpage.
- The DNR will hold a public hearing and comment period on the Draft EIS.
- The DNR will consider all comments received on the Draft EIS.
- Final EIS:
- The DNR will post the Final EIS on this webpage, along with all comments received and a Comment Response document.
- The Comment Response document will summarize comments received along with the DNR's responses, including any revisions made to the Final EIS.
- The DNR will issue a determination of compliance with the Wisconsin Environmental Policy Act (Ch. 1.11, Wis. Stats).
- No DNR permit decisions will be issued until after the Final EIS has been published.
Previous Enbridge Project Proposals in Wisconsin
Line 3 Replacement Project
Enbridge owns and operates the 324-mile-long Line 3, originally installed in 1968 between Alberta, Canada and Superior, WI. Enbridge conducted internal inspections of Line 3 as part of its ongoing system-wide pipeline integrity program and proposed a replacement of Line 3 in Wisconsin (referred to as Segment 18).
In Wisconsin, the Line 3 Replacement project consisted of replacing approximately 14 miles of the existing 34-inch-diameter pipeline with new 36-inch-diameter pipe. In Wisconsin, the Line 3 pipeline replacement is adjacent to the existing Enbridge right-of-way from the Minnesota state border to the Superior Terminal in Douglas County.
The DNR published an Environmental Impact Statement (EIS) for the Line 3 Replacement Project. The final EIS is available at these links:
- Line 3 waterway and wetland permit and WEPA compliance determination for the Enbridge Sandpiper/Line 3 final EIS
- Enbridge Sandpiper/Line 3 final EIS, Volume 1, Chapters 1 - 9
- Enbridge Sandpiper/Line 3 final EIS, Volume 2, Appendices
Enbridge received their necessary local, state, and federal permits and approvals for the Line 3 Replacement project in Wisconsin. Construction of the Line 3 Replacement Project concluded in 2018.
Sandpiper Pipeline Project
In 2014, Enbridge applies for permits from the DNR for the Sandpiper Pipeline Project. In Wisconsin, the proposal consisted of 14 miles of new 30-inch diameter pipeline. The full project would have been approximately 616 miles long, running from North Dakota, through Minnesota to Superior, WI.
The DNR published an EIS, joint with the Line 3 Replacement Project. In a December 19, 2016 letter to the DNR, Enbridge withdrew their permit applications for the Wisconsin portion of the proposed Sandpiper Pipeline project.
