Document Description
The Removal Action Workplan (RAW) specifies cleanup procedures to be implemented at the Melrose Elementary School Site (Site) for excavation, removal, and off-site disposal of soils contaminated with arsenic. Excavation, sampling and site restoration activities are expected to occur over a sixty-day period. Approximately 1,650 cubic yards of contaminated soil will be excavated and hauled off-site from six localized areas. Based on the analytical results provided in the Supplemental Site Investigation (SSI) report dated March 11, 2005 and the Removal Action Workplan most of the arsenic-impacted area will be excavated to a depth of 2.5 feet below ground surface (bgs). The excavation depths will not exceed 4 feet below ground surface. After the arsenic impacted soil is removed, confirmation soil samples will be collected at the base and on the sidewalks to verify the Site Specified Cleanup Goals (SPCG) have been met. Arsenic will be cleaned-up to levels <= 12 milligrams per kilogram (mg/kg). SPCG were derived by calculating standards used for residential, unrestricted land use scenario and reviewed by a DTSC toxicologist.

Notice of Exemption

Exempt Status
Categorical Exemption
Type, Section or Code
Section 15330
Reasons for Exemption
The activity is a minor cleanup action to be taken to prevent, minimize, stabilize, mitigate, or eliminate the release or threat of release of a hazardous waste or substance, with the removal action costing approximately $380,000. The approved RAW includes an Excavation Plan, Engineering Evaluation/Cost Analysis, Health and Safety Plan, Transportation Plan Equivalent, and Dust Control Measures. Fieldwork will be conducted utilizing these engineering, administrative, and work practice controls. The project will not have a significant effect on the environment because of the relatively small volume, short project duration, and the controlled manner in which contaminated soils will be excavated, loaded onto trucks and taken off-site for disposal. The Site is not on the Hazardous Waste and Substances Sites list or in a sensitive cultural or biological resource area.
