BOSTON - EPA and the New Hampshire Department of Environmental Services will host a public hearing at 7:00 pm on Thursday, August 18, 2005 to accept comments on the recently released proposed cleanup plan for the Troy Mills Landfill Superfund Site in Troy, NH. Before beginning the formal public hearing, EPA will present and answer questions about the proposed cleanup plan. The meeting will be held at Meadowood Assembly Hall, on Bowkerville Rd. in Fitzwilliam.

The proposed cleanup plan was released in mid-July for public comment. The 30-day public comment period, will end on August 19, 2005. EPA will consider and respond in writing to all comments received on the cleanup proposal during the public comment period before issuing a final cleanup decision later this year.

EPA recently completed a multi-million time-critical removal action at the site which included the excavation and off-site disposal of 7,692 buried drums, 9,924 gallons of flammable liquid waste, 3,099 cubic yards of sludge, and excavation of 26,244 tons of heavily contaminated soil. Residual, less contaminated, soils were left in place and capped with a two-foot permeable soil cap. The proposed cleanup plan, which addresses the remaining groundwater and residual soil contamination at the site, includes the following components:

    • Maintaining the newly constructed permeable soil cap over the drum disposal area to allow precipitation to flow through the cap and facilitate the cleanup of the groundwater. The cap is being vegetated to provide stability and prevent erosion.
    • Allowing naturally occurring processes to continue reducing contaminant concentrations in the groundwater.
    • Capturing any potential free product, called light non-aqueous phase liquid (LNAPL), in the existing series of interceptor trenches constructed by EPA in 2003. The LNAPL will be disposed of off-site.
    • Establishing institutional controls that restrict the use of contaminated groundwater for drinking water purposes; restrict excavation activities in the area of the cap; and require notification of any changes in the use of the land.
    • Implementing a comprehensive monitoring and sampling program to evaluate groundwater, surface water, sediment and wetlands at the site to ensure that natural attenuation processes are continuing as expected.
    • Monitoring and maintaining the cap.
The Administrative Record, which includes documents that form the basis for EPA's selection of the proposed cleanup plan, is available for review at the Gay-Kimball Library and the EPA Records Center, as well as on the world wide web )
