This project includes the issuance of a right-of-way permit for the operation and maintenance of an existing transmission power line located on Horicon National Wildlife Refuge lands. The existing power line was on the refuge at the time the land was acquired, and the Service is currently administering refuge lands subject to the existing 20-foot-wide perpetual easement. The applicant, American Transmission Company, has requested to expand their existing 20-foot easement to include an additional 20 feet of new ROW on the northern edge of the project footprint, making the existing easement and proposed ROW addition equal to a 40-foot corridor. This requested addition is intended to accommodate the swing of the power line wires and allow for vegetation removal within the swing space.
The draft compatibility determination is now available for public review and comment for 15 days from February 24 to March 11. A hard copy of this document is posted at the Refuge Headquarters (W4279 Headquarters Road Mayville, WI, 53050). Please let us know if you need the documents in an alternative format. Concerns expressed during the public comment period will be addressed in the final. Comments may be emailed to horicon@fws.gov, mailed to the refuge headquarters or dropped off at the front information desk.
