(ATLANTA – January 26, 2012) The U.S. Environmental Protection Agency (EPA) and CTS Corporation have reached an agreement, an Administrative Order and Settlement Agreement on Consent (AOC), to conduct a Remedial Investigation and Feasibility Study (RI/FS) at the CTS of Asheville, Inc. Site in Asheville, NC.

The RI serves as the mechanism for collecting data to characterize site conditions, determine the nature and extent of contamination, assess risks to human health and the environment, and conduct treatability testing to determine the nature and potential performance and cost of treatment technologies. The FS is the mechanism for the development, screening and detailed evaluation of alternative remedial actions.

According to the terms of the AOC, CTS Corporation will:

    Submit a Non-Aqueous Phase Liquid (NAPL)Work Plan and Health and Safety Plan within two weeks. The NAPL Work Plan will be implemented concurrently with the January 13, 2012 Soil Vapor Extraction Confirmation Sampling and Analysis Plan, Revision 7 (“CSAP”).
    Submit a Work Plan related to monitoring of private drinking water wells that are located within a one mile radius of the former plant at the Site.
    Submit a Vapor Intrusion Assessment Work Plan.
    Submit a RI/FS Work Plan and a RI Sampling and Analysis Plan to address all other known or suspected exposure pathways.

CTS Corporation has informed EPA of their desire to offer whole house water filtration systems for homes within a one mile radius of the Site that rely on wells as their drinking water source. This is an interim measure until the RI/FS process selects the final remedy. All costs of installation and maintenance of the filtration systems will be borne by CTS. The filter media will remove any contaminants that may be in the ground water. EPA will initiate an immediate effort to inform the community, and solicit comments from the community, about this interim measure.

All work associated with the AOC will be under the authority and oversight of EPA’s Superfund Remedial and Site Evaluation Branch.

The CTS of Asheville, Inc. site is located in south Asheville, near the Skyland Community. Operations occurred at the CTS site from the early 1950’s until 1986. CTS Corporation manufactured electronic components at the facility from 1959 to 1985. The chemical compound trichloroethene (TCE) was used by CTS to clean and/or degrease metal objects prior to electroplating. In 1987, the original 57-acre property was sold to Mills Gap Road Associates (MGRA) who developed a residential neighborhood on approximately 48 acres, leaving a fenced 9-acre site where the manufacturing had occurred.
