The companies working to build a power line from Duluth to Wausau have won a small victory today. The Marathon County Board has decided to begin negotiations with American Transmission Company. 5 years ago, the board went on record opposed to the line. Tuesday, board members voted to begin negotiations with ATC on running part of the line through some county-owned land. Opponents were hoping the board would refuse to authorize negotiations, which would have added another hurdle to the project. Once an easement is negotiated, the county board must vote again on whether to accept it or reject it.
