List of Contaminated Sediments Technical Advisory Group Sites

EPA has identified the following sites as warranting review by the Contaminated Sediments Technical Advisory Group (CSTAG). The sites were selected because they are large, complex or controversial; quantifiable criteria were not used to develop the list. The list will grow as more sites are placed on the National Priorities List (NPL) or as additional information becomes available for sites undergoing investigation.

As the CSTAG reviews each site, links to the CSTAG’s site recommendations and the Region’s response to the recommendations will be posted below. These documents will also become part of the site’s administrative record.
