This one acre site was occupied from 1967 to 1986 by the manufacturer, Power Semiconductors. Past processes resulted in the generation of hazardous metal hydroxide sludge which was disposed in an on-site, unlined waste lagoon. In addition, effluent from the facility's industrial waste water treatment system was discharged to two on-site dry wells. The site is currently being used for storage of industrial equipment, but is scheduled for clean-up and re-development by the current landowner.

Current Status
[Back to Top]

While the EPA RCRA Corrective Action Program remains involved, in 2004 this site was referred to EPA Superfund. As a result, in the summer of 2005 an extensive soil gas sampling effort was performed by EPA. The results of this work led to a further assessment of potential human exposure to contamination, which was completed in October 2005. However, the EPA continues to evaluate ways to further characterize releases of hazardous waste at or from this facility, with the short-term goal of demonstrating Human Exposures are Controlled.
