EPA RCRA ID: DED002331536
The Resource Conservation and Recovery Act (RCRA) is the public law that creates the framework for the proper management of hazardous and non-hazardous solid waste. Corrective action is a requirement under RCRA that facilities that treat, store or dispose of hazardous wastes, or did so in the past, investigate and clean up hazardous releases into soil, groundwater, surface water and air. For more information, and for more information on RCRA-specific terms used on this page, please visit EPA’s umbrella RCRA web page or EPA’s RCRA Corrective Action page.

Cleanup Activities
A Corrective Measures Study (CMS) was submitted by W.L. Gore & Associates, Inc. for the Site on March 13, 2012. The CMS recommended that institutional controls, in the form of an environmental covenant (EC), be implemented as the optimal corrective measure. The institutional controls will establish "restricted areas" that will be restricted to non-residential use. These restricted areas will be presented on a map in the EC and will consist of designated portions of the Shed Building and the Surface Impoundment Area. Additionally, use of the Shed Building basement will be restricted. A Statement of Basis for Corrective Action was issued by the Delaware Department of Natural Resources and Environmental Control's (DNREC) Hazardous Waste Management Section (HWMS) on August 26, 2012. A Record of Decision (ROD) was advertised by DNREC-HWMS on October 10, 2012. The thirty (30) day coment period for the ROD did not produce any significant comments.
On August 19, 2020, the EPA conducted a Long Term Stewardship assessment to assess whether the remedy was implemented and protective of human health and the environment. EPA determined that the remedy institutional and engineering controls have been fully implemented and no control deficiencies were identified.
All environmental assessment and corrective action activities have been completed at the site, ending with the implementation of an Environmental Covenant which contains activity and use limitations as described in the Status section above.
Cleanup Actions or environmental indicators characterizing the entire facility are shown below. This listing, and all the data on this page, come from EPA’s RCRAInfo and are refreshed nightly to this page. For this table, a blank in the Status column could mean the action either has not occurred or has not been reported in RCRAInfo.

Facility Description
Link to a larger, interactive view of the map.
Gore manufactured wire and cable products used primarily for signal transmission in the communications, computer, and aerospace fields at the Facility. The Facility is currently used as corporate offices. As a result of the manufacturing processes, small amounts of hazardous waste were generated and managed on-site prior to disposal. The wastes included, solvents, still bottoms, metals and caustic salts. Currently, the Facility contains only a portion of the process lines or solid waste management units that historically existed since 1961.
In the early 1980's Gore applied for and obtained an interim status Resource Conservation and Recovery Act (RCRA) permit from the EPA for certain proposed operations at the facility. Shortly thereafter, Gore requested that the permit be canceled based on changes in the proposed operations, which eliminated the need for such a permit. Formal closure of the permit, however, was not obtained at that time. Therefore, the facility has been included in EPA's RCRA Corrective Action 2020 initiative.
Contaminants of concern were PCE and TCE that were found in sub-slab gas vapors.
Institutional and Engineering Controls at this Facility
Activity and Use limitations as described in an Environmental Covenant filed with New Castle County, DE include establishing "restricted areas" that will be restricted to non-residential use. These restricted areas will be presented on a map in the EC and will consist of the Shed Building and the Surface Impoundment Area. Additionally, use of the Shed Building basement will be restricted to limited use. Environmental Covenant compliance reporting is required to the EPA and DNREC biannually starting November 2013.
Institutional and Engineering Controls help ensure human exposure and groundwater migration are under control at a cleanup facility. Where control types have been reported by states and EPA in EPA’s RCRAInfo, they are shown below. Not all control types are needed at all facilities, and some facilities do not require any controls. Where there are blanks, the control types may not be needed, may not be in place, or may not be reported in RCRAInfo.
