Automotive Business, Auburn, California

The owners of the subject property were initially cited for violations of various ordinances and regulations after neighboring property owners filed complaints regarding their operations on the property.  The Department of Toxic Substances Control (DTSC) subsequently responded to these complaints, and collected limited soil samples and a sample from a nearby water well.  After glycols were detected in the water sample and elevated concentrations of metals were reported in soil, the owners entered into a Voluntary Cleanup Agreement with DTSC.

The property has been used for decades for vehicle crushing, dismantling, and storage and covers a relatively large area (4.5 acres).  The property has been leased for decades to multiple tenants that have had various business operations conducted over time.  A Phase I site assessment was performed initially to research history of the property and historical use.  Stratus then began working in conjunction with the DTSC to conduct a Preliminary Endangerment Assessment (PEA) on the property after the Voluntary Cleanup Agreement was initiated.  A subsurface investigation was conducted on the property that consisted of field screening shallow soils for metals using X-ray fluorescence, advancing soil borings, and drilling, installing, and sampling monitoring wells on a quarterly basis.  After conducting the assessment and evaluating the data gathered from the field investigations, DTSC has tentatively agreed to close the case once a deed restriction is placed on the property.
