EPA announces major modifications to ongoing VT landfill Superfund site remedy

EPA has proposed major recommended modifications to the ongoing remedy of the BFI Rockingham Landfill Superfund Site in Rockingham, Vt., that include an increased timeframe to cleanup groundwater, additional groundwater restrictions, and revised arsenic and lead cleanup levels.

BOSTON, MA, Sept. 18, 2014 -- The Environmental Protection Agency (EPA) has proposed major recommended modifications to the ongoing remedy of the BFI Rockingham Landfill Superfund Site (Site) in the city of Rockingham, Vt., that include an increased timeframe to cleanup Site groundwater, additional groundwater restrictions to prevent exposure to contaminated groundwater, and revised cleanup levels for two contaminants -- arsenic and lead.

EPA is carrying out these measures to ensure that the remedy remains protective of human health and the environment based on changes to the federal and state standards for these two metals. Further, the Agency will be accepting public comment on these recommended modifications from Sept. 11 to Sept. 25, 2014.

The Site is a 17-acre landfill located along U.S. Route 5 and adjacent to the Connecticut River. From 1968 until 1991, the landfill received residential, commercial and industrial solid and liquid wastes. Approximately 1.2 million cubic yards of solid waste were disposed in the landfill during its operation. The majority of wastes were placed in unlined landfill cells. In October 1989, the Site was included on the EPA National Priorities List (NPL).

The 1994 cleanup plan, also known as the Record of Decision, estimated that the groundwater restoration aspect of the cleanup would be complete in a 15-year timeframe. By the spring of 2009, however, long-term monitoring results indicated that Interim Groundwater Cleanup Levels would not be achieved in that timeframe. At EPA's request, consultants to BFI Waste Systems of North America, LLC undertook additional investigations of bedrock groundwater, which show Site groundwater will likely meet interim groundwater cleanup levels in 40 to 60 years.
