2.1.1 Narrative
2.1.2 Response Actions to Date
On 8/3/2016, ERRS began clearing and soil excavation activities. As the ERRSs contractor excavates they stockpile and segregate non-hazardous from hazardous soil in preparation for disposal. START utilizing a XRF has delineated hazardous (>5,000 ppm As) soil from non-hazardous (<5,000 ppm As) and also delineated 420 ppm and 68 ppm contours where appropriate.
On 08/09/2016, START collected treatability samples from the hazardous stockpile and shipped off to 3 different labs for bench scale studies.
On 08/11/2016, the OSC and the EPA Community Involvement Coordinator concluded interviews with nearby residents and local elected officials.
As of 8/12/2016, approximately 660 cubic yards of soil have been excavated and stockpiled awaiting disposal.
On 08/15/16, START collected and shipped off samples from both stockpiles (non-haz and haz) for lab analysis for purposes of creating waste disposal profiles.
2.1.3 Enforcement Activities, Identity of Potentially Responsible Parties (PRPs)
All of the previous and current land owners have been designated as PRPs for this Site. However, none have been identified for purposes of conducting the removal action as there is no direct evidence that any of the land owners contributed to a release of hazardous substances during their period of ownership.
Wells Fargo N.A. is currently responsible for the Wiley property but is not considered a PRP because
it acquired title to the property via a foreclosure proceeding and thus has no
liability under CERCLA.
