The Enbridge Energy routine pipeline maintenance of Line 6A may result in the incidental taking of five rare plant species under a permit the Wisconsin Department of Natural Resources proposes to issue for the project.

"Incidental take" refers to the unintentional loss of individual endangered or threatened animals or plants that does not put the overall population of the species at risk.

Enbridge plans to inspect and make any necessary repairs on six segments of existing pipeline identified through Enbridge's pipeline integrity program. The maintenance sites are located on Line 6A at mileposts 0.9042, 0.9193, 1.6032, 1.6459, 1.6759 and 1.7202 in the city of Superior.

The presence of the state threatened sweet colt's-foot, seaside crowfoot, clustered bur-reed and state-endangered neat spike-rush and small yellow water crowfoot have been confirmed in the vicinity of the project site. DNR staff determined that the proposed project may result in the incidental taking of some plants.

Department staff has concluded the proposed project is not likely to appreciably reduce the likelihood of the survival or recovery of the species within the state, or the plant-animal community of which they are a part or the habitat that is critical to their existence.

The conservation measures to minimize the adverse effect on these threatened and endangered species will be incorporated into the proposed incidental take permit.

Copies of the jeopardy assessment and background information on the above mentioned plant species are available at or upon request from Stacy Rowe at 608-266-7012 or The department is requesting comments from the public through May 27 regarding project-related impacts to these plants.

Public comments should be sent to Stacy Rowe by email or at WDNR, P.O. Box 7921, Madison, WI 53707-7921.
