The Allied Paper Inc./Portage Creek/Kalamazoo River Superfund Site is located in Allegan and Kalamazoo Counties, Michigan. The site includes soil and sediment contamination in disposal areas, paper mill properties, about 80 miles of the Kalamazoo River (from Morrow Dam to Lake Michigan), adjacent riverbanks and contiguous floodplains, as well as a 3-mile stretch of Portage Creek. EPA has identified six areas, or operable units (OUs), requiring cleanup. Cleanup has taken place at three of the six areas; operation and maintenance activities and groundwater monitoring are ongoing at these locations. Final cleanup decisions have not been made at the remaining three OUs.  However, several interim cleanup actions have been conducted.

At this time, the site is divided into six cleanup projects known as operable units (OUs):

  • OU #1, Allied Paper Property/Bryant Mill Pond Area;
  • OU #2, Willow Boulevard and A-Site Landfill;
  • OU #3, King Highway Landfill;
  • OU #4, 12th Street Landfill;
  • OU #5, Portage Creek and Kalamazoo River sediments; and
  • OU #7, Plainwell Mill
