A temporary shutdown of the groundwater remedy construction activities was initiated on April 1, 2020 to increase protection of personnel and the community in response to the COVID-19 pandemic. PG&E continued to operate and maintain the Interim Measure "pump and treat" system (also known as IM-3) to ensure the protection of the Colorado River during this period.

The Consultative Workgroup (CWG) is a specific group of key governmental agencies, stakeholders and Tribes established to facilitate participation in the Site investigation and remediation process. The CWG usually meets quarterly. A CWG meeting was held on October 7, 2020. 

The U.S. Department of the Interior (DOI) conditionally approved the Final Groundwater Design and the Construction/Remedial Action Work Plan on April 3, 2018. Subsequent to certification of the Final SEIR, DTSC conditionally approved the Final Groundwater Design and the Construction/Remedial Action Work Plan on April 24, 2018. The conditional approvals can be viewed here. The Final Groundwater Remedy Design document can be downloaded here.

Upon completion of the soil investigation field work and discussion of soil data, DTSC and DOI concurred with PG&E to begin the soil risk evaluation process on June 20, 2017. The risk assessment assessed potential human health and ecological risks based on soil sampling data. This information will assist risk management decisions on the need for soil remediation, if any. The Soil Risk Assessment Report plus errata were approved on May 29, 2020. The main report can be downloaded here. The appendices to the report are available here. 

Concurrently, the preparation of the Soil RFI/RI Report (also called the RFI/RI Volume 3 Report) has begun. The Soil RFI/RI Report will present the findings and conclusions of the soil investigation field work and the conclusions from the Risk Assessment. The Soil RFI/RI Report is anticipated to be completed in late 2021. 

A Phase 1 Construction initiation meeting was held on October 2, 2018, in Needles, California. Over eighty individuals participated in the initiation meeting, including representatives from DOI, DTSC, the U.S. Fish and Wildlife Service, Native American Indian Tribes (Fort Mojave Indian Tribes, Chemehuevi Tribe, Cocopah Indian Tribe, and the Colorado River Indian Tribes), and key construction contractors involved in the initial construction activities. The initiation meeting covered initial construction activities and schedules, PG&E’s health & safety expectations, DOI’s and DTSC’s expectations, and perspectives of the Tribes.
