RECOMMENDATION(S):

ACCEPT the Keller Canyon Landfill Forensic Audit Technical Memorandum prepared by TRC Solutions, Inc. and Staff Report prepared by Contra Costa Environmental Health staff detailing the investigation of alleged radioactive waste sent to Keller Canyon Landfill from the former Hunters Point Naval Shipyard.

FISCAL IMPACT:

Acceptance of this report is not expected to impact the General Fund.

BACKGROUND:

Contra Costa Health Services (CCHS) is providing this update to the Board of Supervisors (Board) to formally present the Keller Canyon Landfill Forensic Audit Technical Memorandum (Exhibit A) prepared by TRC Solutions, Inc (TRC). The goal of the Forensic Audit was to investigate the potential presence of radioactive and hazardous landfill waste at the Keller canyon landfill, which was reported to originate from the Hunters Point Naval Shipyard (Hunters Point), see newspaper article attached as Exhibit B. TRC concluded that it is very unlikely that radiological materials originating from Hunters Point were disposed at Keller Canyon.

BACKGROUND: (CONT'D)

On November 9, 2020, CCHS staff and TRC conducted a virtual community meeting to present TRC’s findings to the local community and to provide the Board with feedback on the community’s response to these findings. The complete audio for the November 9, 2020 Keller Canyon Community Meeting can be found at https://cchealth.org/z/video/eh-solid-waste-keller-110920.mp4 and is included as Exhibit C. The CCHS Staff Report (Exhibit D) summarizes the investigation.

CONSEQUENCE OF NEGATIVE ACTION:

If the recommendations are not approved, this update would not be accepted.
