GE "� GENESIS ENGINEERING&REDEVELOPMENT Howard F. Hold, P.G. May 29, 2009 Page 2 Department of Water Resources ("DWR")records and a field reconnaissance,no water-supply wells were identified on this property. A follow-up field reconnaissance conducted on May 21, 2009, did not identify any evidence of a water-supply well associated with the building. Comment: "There is now a large silo and two double-wide trailers across the street from the site. Again,these were not included in the site characterization report. It was not evident if these places were on well water." The silo and trailers were placed on the property east of the Site approximately one year ago, and were present when the Site characterization was completed. It is our understanding that the silo is used for grain storage and the trailers house seasonal workers. As of August 2008 there were no DWR records of a water-supply well on the property. A field reconnaissance in the vicinity of the Site in 2008 did not identify any wells in the vicinity of the silo and trailers. A landowner that was interviewed did indicate that a domestic supply well was proposed approximately 1,500 feet east of the Site. It is possible that this well was being installed to provide water to the trailers. The approximate location of this proposed new well was shown on Figurel O of the Site Characterization Report. A follow-up field reconnaissance conducted on May 21, 2009 did not see evidence of a water-supply well associated with the silo and trailers. The presence of the structures themselves does not appear relevant to the Site Characterization Report or to the Site closure options. Comment: "There has been a breach in the Whiskey Slough levee. Now the majority of the northern area has been flooded. The drilling mud is submerged, and is now continuously discharging to the Delta. This is a violation of the California Water Code and must be stopped immediately. This breech will have a significant impact on the closure strategy." It does not appear that the breach in the levee is recent. Google Earth images dating back to November 2002 (Figures 4 and 5) indicate flooding of the northern parcel. Reports available on GeoTracker for the Kinder Morgan SFPP Pipeline Release Site note an"area with standing water" extending across the western half of the northern parcel dating back to April 2005 (Figure 6). It is not known whether the flooding seen on the SFPP Pipeline figures and Google Earth images is the result of a breach in the levee or seasonal flooding resulting from poor drainage. However, it seems unlikely that the flooding viewed in the early November 2002 (Figure 4) and late July 2004 (Figure 5) Google Earth images is the result of heavy rainfall, based on the time of year of these images. It appears that the breach may have occurred between May and November 2002.
