Erie Pier was purchased by the Duluth Seaway Port Authority in 1979 from the Zenith Dredge Company for the purpose of constructing a Confined Disposal Facility (CDF). Today, the Port Authority operates the 89-acre Erie Pier as a recycling facility - termed a Placement and Reuse Facility (PRF) - and acts as local sponsor for all dredging projects in the harbor, working closely with the U.S. Army Corps of Engineers.

According to the Erie Pier Management Plan (http://www.dsmic.org/print.asp?PageID=287) created by the Harbor Technical Advisory Committee/Duluth-Superior Metropolitan Interstate Council, dredged materials are sorted at Erie Pier (based on size) into two grades: coarse and fine.

  • The coarse material (i.e. sand) has been utilized in area road and other construction projects since the late 1980s. It meets Minnesota Pollution Control Agency (MPCA) Tier I standards, which permit its use in any upland location. Wisconsin DNR permits the use of this coarse material in public projects anywhere in Douglas County.
  • The fine material - best described as "reclaimed soil" - has also been tested and found to meet MPCA Tier I standards for re-use, and is being utilized in a number of projects around the Twin Ports and Minnesota's Iron Range, as well as in a pilot project in Wisconsin.
