NOE - Notice of Exemption

Document Description
Approval of a RAP Amendment by the Department of Toxic Substances Control (DTSC) pursuant to Health & Safety Code, chapter 6.8; chapter 6.5, etc. as submitted on April 11, 2008 by DTSC. The RAP Amendment focuses on excavation and removal of soil impacted with excessive levels of metals, mainly cadmium and volatile organic compounds (VOCs) primarily trichloroethylene (TCE) onsite and treatment of groundwater to reduce VOC concentrations. The purpose of the project is to mitigate impacted soils that exceed the project-specific human health risk criteria to minimize human exposure to the identified chemicals of concern (COCs). The estimate volume of impacted soils is 1,900 cubic yards or approximately 100 truckloads. The cleanup goals for the metals are: the bay area background level using the Lawrence Berkeley National Laboratory 2002 data, California Human Health Screening Levels (CHHSLs), or the Preliminary Remediation Goals (PRGs). After groundwater treatment, soil gas will be measured and results compared to CHHSLs. The screening level for TCE soil gas is 0.53 ug/l. Project activities will commence in June 1, 2008 and are expected to take approximately 45 days to complete. An analysis of project activities upon existing environmental conditions indicates that implementation of environmental safeguards and monitoring procedures are enforceable and made a condition of project approval and will ensure that impacts to the environment will be less than significant. As a result, DTSC finds that the project is exempt from further review under CEQA.
