Background

The Wisconsin Public Service Corp. site is located in Two Rivers, Wis., adjacent to the West Twin River. Currently, about half of the 5-acre former MGP plant is wetland near the river’s shore, accessible by water. The former MGP building and other structures and foundations have been demolished.  A fence was installed around the perimeter to prevent trespassing.
WPSC owned and operated the gas plant from 1925 to 1946 in an area that was historically industrial. Processes included coal carbonization and carbureted water gas. WPSC still owns the site today.

Under Wisconsin Department of Natural Resources oversight, various investigations have taken place since the 1990s. From 2003 to 2005, pilot tests were done to try a then-promising technology called in-place chemical oxidation to treat contaminated groundwater. Routine groundwater monitoring occurs annually.

Site Updates

April 2015

A short-term cleanup is nearly completed at this former MGP site in Two Rivers. For the purpose of this cleanup, the site has been separated into three areas (see below), referred to as Areas A, B and C.

Work has been ongoing since September 2014 which includes securing the area, monitoring the air, excavating and disposing of the contaminated soil and sediment, and stabilizing any remaining contaminated soil on site. All of the stabilization has been completed and the excavation area has been backfilled with stone.

Subsurface structures such as concrete and piping wrapped with asbestos have been removed. Peat is still being transported off site from Areas B and C. This may continue to create some extra truck traffic. There may also be some odors because the peat is contaminated with the waste buried onsite, however, air monitoring is not detecting any off-site effects. Sandbag dikes and an underwater “curtain” have been installed along the river to prevent any contaminated soil from entering the water.

The three areas are:

Workers are reseeding and regrading the property.  When they are done this spring, all of the heavy equipment will be removed, the streets will be opened, and this short-term cleanup will be completed. 

WPSC/Integrys is conducting and paying for the work under an EPA legal agreement called an administrative order on consent.

The agreement includes five other MGP sites in Green Bay, Manitowoc, Marinette, Oshkosh, and Stevens Point, Wisconsin. A separate agreement for another site, WPSC Campmarina MGP in Sheboygan, was signed between WPSC and EPA in January 2007.
