MADISON – Wisconsin is proposing to change its requirements for oceangoing ships arriving in its Great Lakes waters. The change would set ballast water discharge standards to those required by the International Maritime Organization. The proposed change reflects the latest science about reducing the risk from invasive species carried in the ships’ ballast water, state officials say.
The proposed modifications to a general permit issued by the Wisconsin Department of Natural Resources to large oceangoing commercial ships will be the subject of a public hearing January 26 in Superior.
