Document Description
This project includes the excavation and off-Site disposal of approximately 74 cubic yards of impacted soil (pesticides, metals, and PCBs) and capping (hardscapes, buildings, clean fill, etc.) of naturally occurring asbestos (NOA) exposed soils at Mountain View High School and the adjacent Freestyle Academy (Site). Excavations will be backfilled with clean imported soil and/or on-Site soil. The purpose of the project is to reduce the human health risks associated with the Contaminants of Concern (COCs) in soil at the Site to a level that is acceptable for the planned future redevelopment. Cleanup levels have been established that are protective of human health and the environment and reduce the potential for exposure to the COCs in soil encountered at the Site. There are naturally occurring asbestos (NOA) concentrations in the alluvial soils underlying the entire Site which exceed the Department of Toxic Substances Control (DTSC) Schools Unit guidelines for NOA. To prevent future exposure to Site soils, all soil will be capped with either classroom buildings, hardscape, artificial turf, or capped with clean import fill soils reviewed and approved by the DTSC. In addition, a long-term monitoring and maintenance plan to control potential future exposure to the impacted material will be required.
