EPA RCRA ID: CTD089623318
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.

This facility achieved a "Remedy Construction Complete" determination on May 18, 2011. The waste storage area was closed in accordance with RCRA regulations, and contaminated soils in many portions of the property were excavated and disposed of off site. A soil vapor extraction system was installed to address contamination in soil beneath an on-site building. A multiphase extraction system was also installed to address contamination in soil and groundwater.
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.

This facility was formerly used to research, develop, and manufacture airborne radar systems, electronic test equipment, gyros, platforms and transducers for the defense and aircraft industries from the late 1960s until the mid-2010s. Manufacturing processes included metal parts plating and finishing, electronic circuit board production, and various sensor component wiring and harness operations. Generated wastes included spent halogenated solvents, commercial unused chemicals, and acids, all of which were managed in a greater than 90 day hazardous waste storage area.
This approximately 78 acre facility is located in a mixed industrial/residential area of Norwalk, CT. According to the US Geological Survey's National Hydrography Dataset, this facility is located in the Saugatuck River-Frontal Long Island Sound watershed and the nearest fresh surface water body is located approximately 500 feet away. Geology in this area has been observed to be influenced by shallow groundwater.
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.
