Site Description
[Back to Top]

The Pownal Tannery site is located between Route 346 and the Hoosic River in the Village of North Pownal, in Bennington County, Vermont. The site was a former hide tanning and finishing facility owned by the Pownal Tanning Company, Inc.. It has been inactive since 1988 when the company declared bankruptcy. The site consists of three contamination sources: the tannery building complex, a lagoon system, and the tannery's sludge landfill. In total, the Pownal Tannery site encompasses approximately 28 acres. From approximately 1937 until 1962, untreated tanning process wastewater was directly discharged into the Hoosic River. A lagoon system comprising six lagoons, was constructed in several stages between 1962 and 1971 to receive the tannery's wastewater. In 1982, a state permitted lined landfill was constructed on site which received sludge dredged from a portion of the lagoons. The tannery landfill is situated on a parcel of land across from the Hoosic River and southwest of the tannery building complex. In 1987, two-thirds of the landfill was covered and closed. The remaining portion remained uncovered until 2001. The area is a rural and residential community with approximately 3,500 residents. The nearest residences are approximately 200 feet from the site and rely upon groundwater from private wells for their water supply. While some site related contaminants have been detected in residential wells in the past, current sampling data indicates that safe drinking water standards are not being exceeded.

Threats and Contaminants
[Back to Top]

The groundwater, soil and lagoon/landfill sludge are contaminated primarily with metals, semi-VOCs, and dioxin. Metals, semi-VOCs and dioxin have been found in site soil/sludge and on building materials at levels that pose an unacceptable direct contact threat. River sediments associated with the Hoosic River are contaminated with several metals, with some exceeding federal benchmark criteria indicating a potential adverse impact to aquatic organisms. However the data indicate that there are unknown sources other than the Pownal site associated with this contamination. Access to the site is partially restricted. While sampling data indicates that the site has not adversely affected the nearest residential wells, continued migration of contaminated groundwater could present a future human health threat and long-term groundwater monitoring will be performed.

Cleanup Approach
[Back to Top]

The site is being addressed in three stages: two initial actions and a final long-term remedial phase which will address contamination at the entire site.

Response Action Status
[Back to Top]

Initial Action Following an initial EPA site evaluation in 1993, a time-critical removal action was taken in 1993 and 1994 to remove 13,000 pounds of contaminated material left behind in drums and tanks within the tannery buildings. Additionally, site access restrictions were put in place but were subsequently compromised by trespassers. This action mitigated the immediate threats to the community.

Seconday Action Between 1995 and 1998, EPA completed an additional preliminary investigation of the source areas at the site, which included the collection of samples at the lagoons, the landfill and tannery building. In March of 1999 EPA made a determination to address two of the three source area's of contamination at the site. Beginning in the summer of 1999 EPA began a cleanup which included decontamination and demolition of tannery buildings, removal of all underground tanks, removal of contaminated soil under tannery buildings to the on-site landfill, capping the landfill and repairing the leachate collection system at the landfill, and excavation of a small quantity of tannery waste that had been deposited adjacent to the Hoosic River. This action was completed in the Spring of 2001. The former tannery building area was restored and is currently being used recreationally. The state of Vermont is performing the operation and maintenance at the former tannery building location and at the landfill.

Final Action In 2002 EPA completed a Remedial Investigation and Feasibility Study (RI/FS) to further determine the nature and extent of contamination at the third source area at the site; the sludge lagoon area. This study also addressed potential contamination in the surface water/sediments of the Hoosic River, as well as potential contamination in the groundwater. The RI/FS and proposed cleanup plan was released to the public in 2002.
On September 30, 2002 EPA signed the Record of Decision outlining EPA's final decision regarding how the remaining site contaminants would be addressed. The cleanup plan for the site will address contaminated lagoon sludge where elevated concentrations of hazardous substances were detected. Among the contaminants detected at elevated levels are dioxin, chromium, lead, arsenic and benzo(a)pyrene. This remedy entails the excavation and consolidation of tannery lagoon waste, construction of a low permeability cap over the consolidated wastes on site, long-term monitoring of river sediments and ground water, and institutional controls to protect the cap from disturbance and to prevent ground water consumption and excavation of waste in the lagoon area.

The selected remedy is a comprehensive approach for the tannery site that will address all current and potential future risks caused by site wastes. At the former tannery lagoons the cleanup will prevent direct contact risks with contaminated lagoon waste and will significantly decrease further off-site migration that the lagoon sludge could cause through leaching to the ground water or erosion to the adjacent river through flooding events. As a result of the previous removal actions, the soil and sludge contamination in the lagoon area was the only remaining area needing further cleanup measures. Cleanup activities began in July of 2003 and were completed in September 2004. The State of Vermont is currently performing Operation and Maintenance activities at the former lagoon area/new landfill.

On September 28, 2007 EPA signed an Explanation of Significant Differences to document a modification to the 2002 Record of Decision. Specifically, 1) the extent of the Institutional Controls required for the site have been further characterized and defined, 2) the monitoring requirements for the Operation and Maintenance component of the remedy have been detailed, and 3) a determination that a limited portion of a protective earthen berm adjacent to the Hoosic River and the new landfill is an integral component of the remedy. The State of Vermont has concurred with this determination.

Environmental Progress
[Back to Top]

The initial actions to remove liquid and bulk hazardous materials remaining in the tannery buildings reduced the potential for accidental exposure to hazardous wastes at the site. The secondary measures to completely address building contamination and to close the landfill addressed potential exposures to two of the three source areas at the former tannery. The RI/FS identified the risks and issues relating to the remaining contamination at the site. The final action taken in 2003 and 2004 addressed the remaining concerns at the site.

Current Site Status
[Back to Top]

EPA has completed the Remedial Action at the site to consolidate and cap the lagoon sludge. Initiation of construction activities began in July 2003. Cleanup of the Lagoon Area was completed in September of 2004. Operation and Maintenance activities are currently being conducted by the Vermont Department of Environmental Conservation.

In 1999, the town of Pownal was awarded a site re-development grant by EPA . The purpose of this grant was to aid the town in their identification of potential reuse options at the site. With the involvement of the community, a reuse assessment report was completed in February 2001. The town of Pownal's identified future land use objectives served as part of EPA's basis for future remedial action objectives. Construction of a waste water treatment facility at the former lagoon area was completed in 2006 and recreational development in the lagoon area is currently being evaluated by the Town of Pownal in the adjacent area. Groundwater and river sediments are sampled annually.
