Site Description
The Japanese Auto Wrecking (JAW) site (no longer operating at this location) originally occupied approximately 1.7 acres.  The site (located at 7777 262nd Street in Kent, Washington) is a former auto wrecking yard that was referred to the EPA’s Emergency Response Unit by the Washington Department of Ecology, the Washington State Patrol, and the EPA’s Resource Conservation and Recovery Act (RCRA) division.  The site located near other auto wrecking yards, is within 0.25 mile of the Green River, and within 0.5 mile of residences.  Prior to their February 2003 eviction, Japanese Auto Wrecking had taken over approximately 5.72 acres of the former Astro Salvage property.  During the START site visit on February 13, 2003, oil was observed floating on surface water and strong petroleum odors were noted near a car-crushing area on the Japanese Auto Wrecking property.  Workers on site reported dumping of thousands of gallons of gasoline directly into the soil at several locations.  The site was closed by Washington Department of Labor and Industries in January, 2003, due to unsafe working conditions.  On February 27, 2003, the EPA responded to the site due to the potential for buried chlorine gas cylinders to leak.  On May 2, 2003, the EPA defined the entire 15 acre property (this includes the approximately 8 acres formerly occupied by Japanese Auto Wrecking) the site area.  


Current Activities
The air sparge/soil vapor extraction remediation system continues to operate on a full-time basis since July 2005.  The system is monitored on a weekly basis, but not limited to manifold gauges, air compressor, and vacuum blower.  In addition to the aforementioned monitoring, oxygen, carbon dioxide, Lower Explosive Limits, and Volatile Organic Compound readings have been recorded using a portable MultiRae IR with photoionization detector (PID).  


Planned Removal Actions
Continued monitoring of the air sparge/soil vapor extraction remediation system this includes the collection of air and groundwater samples.

Key Issues
Further determine extent of groundwater & soil plume(s) to ensure effectiveness of the extration systems.
