Document Description
PG&E has implemented remediation activities to clean the groundwater impacted by historical chromium discharges from the Hinkley Compressor Station, pursuant to existing Water Board orders. The Water Board has worked with PG&E to develop feasible remedial approaches to comprehensively contain and remediate the chromium plume. The EIR evaluates at an equal level of detail six project alternatives, each with different types and combinations of remediation activities. The project area for the analysis encompasses the chromium plume area; adjacent areas to the north, east and west where the plume may be defined in the future (due to migration and addition investigation); and where monitoring activities may occur and areas of potential effects due to groundwater pumping from the remediation alternatives.
