The 1-1/2-acre Wisconsin Public Service Corp. Campmarina manufactured gas plant site is located at 732 N. Water St., Sheboygan, Wis. on the north bank of the Sheboygan River. Currently, it is used as a park and marina with a river walk located immediately adjacent to the river shoreline.

WPSC owned and operated the gas plant from 1872 to 1929 in an area that was historically industrial. Processes included coal carbonization and carbureted water gas. Today, the city of Sheboygan currently owns the property.

EPA Region 5 is working on former MGPs in Wisconsin and Illinois.

A Community Advisory Group (CAG) is one way the community can get involved. Learn more about CAGs

Great Lakes Legacy Act

The Sheboygan River and Harbor Site and the Wisconsin Public Service Corporation Campmarina Manufactured Gas Plant Site are being cleaned up under the U.S. Environmental Protection Agency’s Superfund program. The EPA is also using Great Lakes Legacy Act funds to clean up additional areas in the Sheboygan River that are outside the jurisdiction of the Superfund program.

Site Updates

March 2014

EPA is proposing no further action on the upland section of the WPSC Campmarina MGP site because it was cleaned up by WPSC under the supervision of Wisconsin Department of Natural Resources from November 2000 through May 2002.

Follow‑up testing and further study have shown that the cleanup work achieved, or will achieve, all of the objectives identified in the 2000 WDNR cleanup plan. These objectives include reducing the potential for site contaminants to come in direct contact with people, preventing contaminated runoff flowing into the river, and preventing contaminants leaching into underlying ground water. In addition, WDNR required that formal controls such as deed restrictions be placed on the upland area to restrict land and/or ground water use and to ensure that the cleanup continues to be effective. WPSC/Integrys, the owner of the property, was determined to be responsible for the environmental problems in the area.  The company has paid for the cleanup and studies, so far.

The company also cleaned up the sediment and shoreline in 2011.  Details can be found in a document called the “record of decision" (PDF) (34pp, 3.5MB).  Under a 2011 legal agreement called a consent order, EPA required WPSC/Integrys to build an underwater barrier called a coffer dam and dig up contaminated sediment and soil from the shoreline.  This phase of the project was treated as a “time-critical removal.”  Another document called an Action Memorandum (PDF) (53 pp, 4.56MB), explains that cleanup.

The main pollutant is polynuclear aromatic hydrocarbons, or PAHs, which is present in what EPA calls NAPL, or non-aqueous phase liquid.  NAPL does not mix with water.

EPA also ordered the company to clean up PAH-contaminated sediment near Boat Island to prevent the movement of PAHs from the Campmarina site.  If this sediment had not been removed, it could have interfered with the PCB cleanup of the nearby Sheboygan River and Harbor site.

The river portion of the cleanup under Superfund has been completed and restoration using Great Lakes Legacy Act funding was done in 2012.  The Great Lakes Legacy Act is administered by EPA’s Great Lakes National Program Office (see box above).

WPSC/Integrys was originally required to study sediment, ground water, and soil after a consent order was signed between the company and EPA in January 2007.

A separate agreement for six other MGP sites was signed in May 2006 in Marinette, Manitowoc, Oshkosh, Two Rivers, Green Bay and Stevens Point, Wisconsin.
