In the Fall of 2008, EPA collected sediment samples in the Delaware River basin in areas contiguous to the General Chemical Corporation's (GCC) facility. The data resulting from this effort indicated elevated levels of arsenic, lead and DDT in the sediment media. EPA is currently working with the facility to define the extent of contamination and to develop interim remedial measures to address any potential risk
The former General Chemical facility also known as the Delaware Valley Works (“DVW”) was a chemical manufacturing plant located in Claymont, New Castle County, Delaware (“Facility”). The Facility consists of approximately one hundred acres, which is divided by Route 13 into two separate plants, referred to as the “DVW North Plant” and “DVW South Plant”. Two-thirds of the DVW North Plant is located in Pennsylvania with the remainder situated in Delaware. Virtually all of the DVW South Plant is located in Delaware. A variety of inorganic chemicals and pesticides were manufactured at the Facility during different periods since it began operation in the very late 1890’s. General Chemical acquired the Facility from Allied Signal in 1986. Allied Signal retained ownership of several contiguous parcels of property upon which chemical operations were conducted and continue today.
In October 2002, General Chemical and certain of its affiliates filed a voluntary petition in the United States Bankruptcy Court for the District of Delaware for reorganization relief. General Chemical subsequently emerged from bankruptcy under an approved Reorganization Plan in October 2003
RCRA Corrective Action activities at the GCC facility are being conducted under the direction of EPA Region 3 with assistance from the State.
In September 2000 EPA issued an Administrative Order to the General Chemical Corporation which requires a facility wide investigation and cleanup of the former GCC facility in Claymont, DE. The Administrative Order was issued pursuant to Section 3008(h) of the Resource Conservation and Recovery Act (RCRA). The requirements of the order include:
• Interim Measures/Stabilization to achieve the initial goal of controlling ground water releases and controlling current human and ecological exposure to contaminated media;
• RCRA Facility Investigation (RFI) if warranted, to provide more in-depth information about Solid Waste Management Units (SWMUs), and;
• Corrective Measures Study (CMS) if warranted, to propose final cleanup actions needed.
GCC, with EPA and State oversight, has completed a Phase I and Phase II RFI. This included the collection of groundwater and soil samples for 28 SWMUs. The data resulting from these investigations will be used to evaluate and characterize the nature and extent of potential contamination. EPA and the Delaware Department of Natural Resources and Environmental Control will oversee all investigations, interim actions and cleanup activities conducted at the GCC facility.
Metals, volatile organic compounds and pesticides, including DDT, are the main constituents of concern found in soils, sediments and groundwater at the facility.
Institutional controls, if required, will be determined at the time of remedy selection.
