Some transformers contain <br /> mineral oil which may contain PCBs. <br /> PG&E maintains responsibility for the transformers, and if the transformers were "PCB <br /> contaminated," PG&E is not required to replace the transformer fluids until a release is identified. <br /> However, evidence of current or prior release was not observed in the vicinity of the electrical <br /> equipment during the site reconnaissance. Based on the lack of evidence indicating release, the <br /> transformer does not appear to constitute a REC in connection with the site at this time. <br /> Releases or Potential Releases <br /> Trash, debris and/or other waste materials <br /> During the site reconnaissance, two trash and debris piles were observed at the southwestern <br /> comer of the site and along the western border of the site and near the former agricultural well. <br /> Responsive ■ Resourceful ■ Reliable 13 <br />
