The U.S. Steel Plant Duluth Works Site, a former steel mill and coking operation, is on both the Federal National Priorities List (NPL) and the State of Minnesota Permanent List of Priorities (PLP). The site is approximately 600 acres (500 land and 100 river sediment). It is located 4 miles south-west of the Duluth central business district and adjacent to the neighborhood of Morgan Park.

Land based contamination has been addressed as specified in the ROD.
