MADISON -- The proposed Y124 transmission line project from Boscobel to Lone Rock may result in the "incidental taking" of a rare bird, dragonfly, turtle and fish under an authorization the 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.

The Y124 69 kilovolt (kV) Transmission Line Project is a rebuild and partial re-route of an existing transmission line between Boscobel and Muscoda in Grant County, then onto Avoca in Iowa County, and then terminates at Lone Rock in Richland County. The Project is owned by American Transmission Company (ATC). Significant portions of the line are proposed for re-route into a combined utility, railroad, and road right-of-way (ROW) to avoid sensitive resource areas.

The presence of the state threatened cerulean warbler (Dendroica cerulea), state endangered and federally endangered Hine's emerald dragonfly (Somatochlora hineana), state endangered ornate box turtle (Terrapene ornata), and state endangered starhead topminnow (Fundulus dispar) 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 birds, dragonflies, turtles and fish.

Department staff concluded that the proposed project will minimize the impacts to the species by adhering to conservation measures; is not likely to jeopardize the continued existence and recovery of the state population of the species or the whole plant-animal community of which they are a part; and has benefit to the public health, safety or welfare that justifies the action.

The conservation measures to minimize the adverse effect on the rare species will be incorporated into the proposed Incidental Take Authorization. Copies of the jeopardy assessment and background information on the cerulean warbler, Hine's emerald dragonfly, ornate box turtle and starhead topminnow are available by searching the DNR website for incidental take public notice or upon request from Stacy Rowe (608-266-7012 or The department is requesting comments from the public through October 14, 2017. Public comments should be sent to Stacy Rowe, DNR, PO Box 7921, Madison, WI 53707-7921or
