NPL Site Narrative for Keddy Mill

Windham, Maine
Cumberland County

iconSite Location:
   Keddy Mill is a 6.9 acre site located at 7 Depot Street in the Little Falls area of the town of Windham Maine.

iconSite History:
   Many industrial activities have been conducted on the Keddy Mill site between 1756 and 1997 including, a sawmill, grist and wool carding mill, wood pulp and boxboard manufacturing, steel and fire suppression piping manufacturing, and a small machine shop and equipment storage. Several buildings on the site have been demolished, and the site currently consists of a single abandoned multistoried concrete building. The site has been vacant since 1997.

iconSite Contamination/Contaminants:
   The primary contaminant of concern at the Keddy Mill site is polychlorinated biphenyls (PCBs).

iconPotential Impacts on Surrounding Community/Environment:
   Contamination from PCBs is widespread throughout the site and inside the abandoned mill building. Rainwater run-off transports PCBs into the adjacent Presumpscot River, potentially contaminating adjacent wetlands. The abandoned building has been vandalized, which indicates that trespassers access the site. Potential contact with PCBs in surface soil and within the mill poses a health threat.

iconResponse Activities (to date):
   Two cleanup actions have been performed on the Keddy Mill site by previous owners. The first involved the excavation of 10.88 tons of petroleum contaminated soil in 1997. The second, during May and July 2010, was performed in accordance with a Toxic Substances Control Act (TSCA) Self Implementing Clean-up Plan (SICP). Only a portion of the SICP was performed which included removal of PCB-contaminated fuel oils in remaining piping and PCB- contaminated sludge, dirt, debris and oily materials from within the building. In addition the current owner has constructed a fence around the site at the request of the Maine Department of Environmental Protection (DEP) to deter trespassers.

iconNeed for NPL Listing:
   Investigation under a Brownfields grant by the town of Windham determined that the site was too contaminated to be addressed under a Brownfields program, and the state of Maine does not have the resources to address the site under their Uncontrolled Site Program. The EPA has received a letter from the governor of Maine supporting placing the site on the NPL.

[The description of the site (release) is based on information available at the time the site was evaluated with the HRS. The description may change as additional information is gathered on the sources and extent of contamination. See 56 FR 5600, February 11, 1991, or subsequent FR notices.]
