Document Description
The proposed involves approval of a Remedial Action Plan (RAP) by the Department of Toxic Substance Control (DTSC) for the proposed South Region High School Site #9 ("the Site") pursuant to Health and Safety Code chapter 6.8. The RAP focuses on excavation and off-site disposal of ~31,740 cubic yards (CY) of onsite soils impacted with metals (mainly antimony, arsenic, barium, cadmium, lead, and mercury), polychlorinated biphenyls (PCBs), volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs), and total petroleum hydrocarbons (TPHs). After completion of the planned excavations, cleanup confirmation sampling and Site restoration will be conducted. If necessary, additional soil volume will be excavated to ensure all impacted soils containing the identified chemicals of concern (COCs) at concentrations exceeding the cleanup levels have been properly removed. The RAP also provides temporary land use controls and a monitoring and contingency plan for Parcel 39 as more fully explained below. The Draft Operable Unit 1 Area A (OU 1A) RAP, Proposed South Region High School #9 and Middle School #4 Site is incorporated by reference.
