PG&E Topock Compressor Station Soil Investigation Project EIR
EIR - Draft EIR
Present Land Use
Soil within the PG&E Compressor Station fence line and surrounding vicinity has been affected by historical releases of hexavalent chromium and other metals. Hexavalent chromium was used as a corrosion inhibitor at the Compressor Station between 1951 and 1985 and is one of the primary drivers of the investigative and remedial activities. The proposed Project involves soil investigation activities including soil sampling and sample analysis, bench scale tests, pilot studies, geotechnical evaluations, and plant and other biota sampling to support ecological risk assessment. The soil sampling and sample analysis are required to determine the nature and extent of soil contamination at the PG&E Compressor Station and surrounding area. The proposed Project would provide sufficient data to support evaluation of possible soil remedial action if determine necessary.
