In 2015, the California Department of Toxic Substances Control (DTSC) approved a Final Remedial Action Plan (RAP) outlining cleanup activities for the Ascon Site. The cleanup plan was approved following a rigorous, multi-year public review and a formal Environmental Impact Report (EIR) process per the California Environmental Quality Act (CEQA).
Since work began in January 2019 on the activities outlined in the RAP, approximately 35 percent of the work has been completed.
The cleanup plan includes the removal and offsite disposal of impacted soils from the Pit F area. The other material (with the exception of Pit F material), will be excavated, stabilized, and placed in an engineered containment area underneath an environmental cap. Once this work is complete, the Site will be capped with environmental barriers and clean soils, and planted with native, drought-tolerant plants. The property will be maintained long-term as fenced open space.
