Background

Type of site

Integrys Energy Group (Integrys), LLC approached EPA in 2007 to address 13 former MGPs in Illinois under EPA’s Superfund Alternative Sites (SAS) program.  The SAS Program takes sites that might otherwise be eligible for the National Priorities List but which will be investigated and cleaned up by a cooperative responsible party, without formally listing the site on the NPL. The South Plant Former MGP site is one of those 13 sites

History

The NSG South Plant former MGP facility was constructed in 1897 by the Waukegan Pipeline Service Company and purchased by North Shore Gas in 1900. The plant was operational from 1898 to 1946 except for a stoppage from 1927 to 1935, and was razed in 1951.  On-site features included a coal gas condensing building, a purifying building, a generator building and a laboratory. Four tar wells and five storage tanks, three for gas and two for oil, were also located on-site.

Contamination of groundwater at the site includes:

Site Updates

March 2014

As of March 2014, 12 rounds of quarterly groundwater monitoring have been conducted, along with 2 rounds of vapor intrusion sampling in the Waukegan Port District and Akzo Nobel properties, and sediment/surface water sampling in the marina and the lake.

On January 22, 2014, EPA approved an RI report that Integrys submitted for review and approval. The Agency is expecting a draft feasibility study (FS) report from Integrys later in the spring of 2014, which will describe alternative cleanup plans for the site.  After EPA reviews and approves the FS—expected in the summer of 2014, the Agency plans to issue a proposed cleanup plan for public comment.  After reviewing comments received, EPA will then issue a Record of Decision selecting a final cleanup plan for the site by fall 2014.
