The Draft Removal Action Workplan Research, Education, and Supporat Area and Groundwater Five-Year Review is now available for viewing. The purpose of a Five-Year Review is to evaluate the implementation and performance of a remedy to determine if the remedy is, and will continue to be protective of human health and the environment.
This is the first Five-Year Review for the Richmond Field Station. The 2014 RAW established the remedial goals and final remedy, including prescriptive requirements and land use controls (LUCs), for all RES soils and groundwater at the Richmond Field Station that were determined to require additional removal actions based on site characterization activities.
The Five-Year Review also includes Revision 2 of the Soil Management Plan, addressing DTSC comments in its April 4, 2019 letter. The Soil Management Plan is to be used for future construction and other soil disturbance which supports the implementation of LUCs by providing a framework to prohibit uncontrolled soil excavation or disturbance activities.
