WOODSTOCK, CONN. (Jan. 3, 2024) – The U.S. Environmental Protection Agency will be holding a hybrid public hearing on the amended Proposed Plan for the cleanup of the Linemaster Switch Corp. Superfund Site in Woodstock, Conn on January 10, 2024.

Public Hearing: January 10, 2024, 7:00 p.m. until all comments are heard.

In-person: Woodstock Middle School Cafeteria, 147B Route 169, Woodstock, CT 06281


During the public hearing, EPA will be accepting oral comments on the preferred remedial alternative identified in the Proposed Plan. No new information will be presented at the hearing. The Proposed Plan presents EPA's proposed changes to the current (ongoing) remedy for the site.

In a 1993 Record of Decision, EPA selected a cleanup plan for the entire site. This remedy required the construction and operation of a groundwater and soil vapor extraction system within the "source area," as well as the extraction and treatment of contaminated groundwater outside the source area (i.e., downgradient areas). Despite 25 years of active site remediation, and evidence that the concentration of contaminants is declining, significant impacts to the soil and groundwater remain. As a result, EPA is proposing to amend the 1993 Record of Decision. The proposed revised remedy includes additional treatment of contaminated soil, as well as modifying the existing groundwater extraction and treatment system. The proposed amended remedy is estimated to cost approximately $11.4 million and is estimated to take approximately one to two years to design and implement.

EPA will be accepting public comments on the Proposed Plan until midnight January 12, 2024. EPA will formally respond to all comments, both written and oral, received during the comment period in a responsiveness summary which will be part of the formal record. EPA will then release its Amended Record of Decision.

The 92-acre Linemaster Switch Corp. Superfund Site houses a former manufacturing facility in Woodstock, Conn. that produced electrical and pneumatic foot switches and wiring harnesses. As part of the manufacturing operations, several chemicals were used at the site including trichloroethene (TCE). Due to the remaining contamination from the previous manufacturing operations, the site was placed on the Superfund National Priorities List in February of 1990. A cleanup plan for the site was selected in a 1993 Record of Decision. Since then, cleanup activities have included the installation of soil and groundwater treatment systems.
