The three phases of the discharged to the East Branch of the cleanup strategy are discussed briefly below.

First phase of cleanup activity- Non-Time Critical In 1983, contamination of groundwater Removal Action (NTCRA). or early cleanup.

Second phase of cleanup activity- Long-Term Site EPA began investigations of the Eastland Cleanup (Remedial Action) for Groundwater (Operable Woolen Mill in December 1998. Unit D. The second phase of cleanup activity, or Operable Unit I, targets the contaminated groundwater EPA placed the Eastland Woolen Mill on beneath the former Eastland Woolen Mill complex and the National Priorities List (Superfund list) in July 1999. downtown Corinna. EPA is currently completing the design for the Operable Unit I cleanup. EPA signed the Action Memorandum to initiate early cleanup action in July 1999. Third phase of cleanup activity­ Sediments/Floodplain Soils within the East Branch of EPA signed the Record of Decision for the Sebasticook River and the Old Dump (Operable Operable Unit I - groundwater cleanup in September 2002. Unit IT). The third phase of cleanup activities, or Operable Unit n, includes all remaining areas of Site EPA completed the excavation and contamination not included within the NTCRA or OU treatment of soil as part of early cleanup I. The areas included within OU II are the sediment action in October 2003. and floodplan soil of the East Branch of the Sebasticook River extending from the end of the NTCRA excavation to Sebasticook Lake, The initial physical survey of the OU U area revealed 14 including the area known as the "Old Dump." This distinct floodplain areas and seven distinct river areas Proposed Plan describes the investigations, results, that were evaluated for contamination as part of the RI and EPA's proposed cleanup approach for these field programs. As part of the Baseline Ecological Risk areas. See Figure 2 for the extent of OU n. Assessment, areas with similar physical characteristics were combined resulting in the identification of two Remedial Investigation Program floodplain soil exposure areas and five sediment exposure areas. See Figure 3 which shows the A Remedial Investigation (RI) involves the collection floodplain and sediment exposure areas. Only the of data to determine the nature and extent of portion of Sediment Exposure Area E which is contamination at a site. The RI for the Eastland contaminated (which is the section about 1 mile north of Woolen Mill was performed from 1999 - 2001. The Sebasticcok Lake) is shown on Figure 3. To identify Remedial Investigation Report for OU I and OU n areas of contamination within these floodplain and and the Feasibility Study Report for OU I were sediment exposure areas, EPA performed the following released in July 2002. studies: A supplemental RI field investigation program was * Placed 392 vapor diffusion samplers in the river bed conducted during 2002 and 2003 to better define the to determine areas where contamination may be extent of contamination in the OU n areas and to present; better assess the potential risks to the ecological f Installed 36 borings into the sediment to delineate receptors from the contamination.
