1.1.1 Incident Category
EPA-lead removal action at a defunct electroplating facility.
1.1.2 Site Description
The site is a large, defunct plating shop, which was shut down by the East Bay Municipal Utility District in 2012, when the utility revoked ED-Coat's permit to discharge wastewater from their operations. The facility has been idle since that time. In the interim, plating tanks full of corrosive solutions have degraded and many of them are now in very poor condition, presenting the threat of a release of toxic, corrosive liquids.
1.1.2.1 Location
715 4th St, Oakland, CA 94607
1.1.2.2 Description of Threat
Large plating tanks in very poor condition present the threat of a release of toxic, corrosive liquids.
1.1.3 Preliminary Removal Assessment/Removal Site Inspection Results
EPA and the California Department of Toxic Substances Control (DTSC) have conducted several sampling operations at the facility over the last few years. This sampling has confirmed the presence of thousands of gallons of corrosive liquids, both acids and bases, many of them with high concentrations of toxic metals. These liquids are stored in badly corroded steel tanks of various sizes. On many of the tanks there are also extensive deposits of corrosive sodium hydroxide crystals, and some of the tanks show evidence of past leaks of contents, including hydroxide crystals on the floor or on adjacent piping.
