Document Description
Pursuant to Chapter 6.8 of the California Helath and Safety Code, the Department of Toxic Substances Control (DTSC) is considering approval of a Removal Action Workplan (RAW) to address soil and groundwater contamination. The cleanup plan title was formerly Removal Action Workplan, but the title has been changed to Remedial Action Plan because of an increase in the estimated cleanup cost. Soil is impacted with asbestos-containing materials (ACM) and petroleum hydrocarbons. Groundwater is impacted with petroleum hydrocarbons and trace concentrations of volatile organic compounds (VOCs). The removal activities consist of:
- excavation of all impacted soil/ fill materials with contaminant concentrations exceeding residential cleanup standards,
- on-site consolidation of impacted soil/ fill materials within an engineered berm along the eastern property margin,
- backfilling excavations with clean fill,
- natural attenuation of organic constituents in groundwater, ground water monitoring and restrictions on ground water use if contaminants remain at concentrations above drinking water standards after impacted soil/fill excavation, ongoing maintenance of and restrictions on the use of the berm.
