Soil Remediation
In conjunction with Building Permit review, the City required Vallco Property Owner LLC to conduct soil testing and provide associated reports. This section provide information about the review that occurred which led to soil remediation and associated requirements with the Santa Clara County Department of Environmental Health (SCCDEH).
City Review of Soil Testing and Other Reports
Soil Characterization Report (SCR) and Environmental Site Management Plan (ESMP): These two documents were reviewed by the City beginning April 2019. It is important to note that the SCR references a 2016 Geosphere soils testing report, which was not provided to the City until April 2019 as part of the SCR.
The following is a list of the documents provided to the City and reviewed by the City in chronological order:
| April 2019: |
|
| June 2019: |

Polychlorinated biphenyls (PCB) Work Plan: Following preparation of the SCR and the ESMP, the City required VPO to prepare a work plan, to be reviewed and approved by the City, to determine the extent of some PCB contamination identified in the SCR and associated reports. The work plan needed to be submitted and reviewed prior to issuance of certain demolition permits.
PCB Investigative Reports and Review: Prior to issuance of any excavation permits, the City required VPO to present the results of the investigation conducted per the PCB Work Plan and also required VPO to submit a soil vapor investigative report. These were reviewed by the City in late 2020/early 2021. These reports have not been finalized since the soil remediation process is now being overseen by the Santa Clara County Department of Environmental Health.
The following is a list of the documents provided to the City and reviewed by the City (unless noted otherwise) in chronological order:
| August 2020 |

Excavation Management Plan (EMP): As a part of the City's requirements to clean up the soil adequately and appropriately, and prior to issuance of any excavation permits, VPO prepared an EMP. The EMP was under review but was not finalized since the soil remediation process was then transferred for oversight by the Santa Clara County Department of Environmental Health.
The following is a list of the documents provided to the City and reviewed by the City in chronological order:
