Hazardous Waste Cleanup: Dassault Falcon Jet Wilmington Corporation in New Castle, Delaware

On this page:

Atlantic Aviation Corporation (AAC) and EPA have worked cooperatively to complete the requirements for Resource Conservation and Recovery Act (RCRA) Corrective Action at the facility located on a portion of the New Castle County Airport. Past releases due to operator error at the facility occurred in an area of the site known as the "Fuel Tank Farm", which includes four underground storage tanks (USTs). Activities were undertaken immediately after each event to contain and cleanup the releases.

Cleanup Status

A fuel spill occurred in 1996. The test results verified that the groundwater concentrations of volatile organic compounds/semi-volatile organic compounds (VOCs/SVOCs) were below applicable levels, namely Maximum Contaminant Levels (MCLs) and Risk Based Concentrations (RBCs). However, the sampling did reveal elevated levels of total petroleum hydrocarbons (TPHs) in the immediate area of the Fuel Tank Farm where the release occurred. Any further investigation or remediation needed concerning this issue has been deferred to DNREC's Underground Storage Tank Branch for oversight. For more information about the investigations, please see the "Site Investigation - Atlantic Aviation Fuel Farm" dated July 1996.

Based on the field investigation and information submitted by the facility concerning past waste practices, EPA has determined that no further corrective action is necessary at this time under the federal RCRA Corrective Action program at the facility. The public comment period on the draft proposal ended on February 26, 2001, and no comments were received. Recently, the entire facility was sold by AAC to Dassault Falcon Jet - Wilmington Corporation, effective October 23, 2000. However, AAC retains the environmental liability for the site.

The AAC facility is located along the east corner of the New Castle County Airport in New Castle, Delaware. AAC had operated at the airport for more than 30 years and offered flight support, flight services and aircraft services. The company leased the property from the Delaware River and Bay Authority, which consists of four hangers and an underground storage tank (UST) farm.

In December of 1999, the Atlantic Aviation administration offices moved from the New Castle County Airport to the Christiana Executive Campus located in Newark, Delaware. More recently, the entire facility was sold by AAC to Dassault Falcon Jet - Wilmington Corporation, effective October 23, 2000. This was an asset purchase and AAC retains the environmental liability for the site.

No further work under RCRA Corrective Action is necessary at this time. Issues related to the Fuel Tank Farm have been deferred to DNREC's UST Branch.
