Surface&Subsurface Contamination Report Page 2 Sandhu Project Project No. 597.1 February 12, 2009 i also a pumping station intended to pre-treat irrigation water for distribution to orchard trees. (See the maps in Appendix A for graphical representations.) Proposed Uses The-two parcels that comprise the Property are reportedly. —owned by a singl legal entity.``'lh oe wners e proposing that the Property bo-leg ly_ split in o 6 lots o�about 40 acres each, ai) shown on the maps in Appendix A Y Prescn : and Recent Use ofthe Property The �PP 4perty zs in �4icultural use, and for the past year has been used to grow A-11nd trees which were planted in mid-2008. The farm building complex was also constructed in 2008. Prior use of the Property appears to have been to raise row or grain crops. Agricultural chemicals including pesticides and herbicides, are periodically applied to the orchard trees. Personnel who are trained to perform this work in accordance with regulations and manufacturers guidelines perform the application. Pesticide use reports are filed with the County Agricultural Commission. Copies of use reports for the past three years were requested on January 15, 2009. The Commission provided nine use reports on February 9. The reports indicate that licensed crop dusting contractor has applied agricultural chemicals and the application has been within accepted guidelines. Irrigation water is provided by the Banta-Carbona Irrigation District, which maintains a canal that forms the north boundary of the Property. Water pumped from the canal is filtered and pre-treated at a pump station located at the building complex. Two large, aboveground poly tanks are used to pre-treat irrigation water delivered to the orchard. Filtered and treated irrigation water appears to also be used for some domestic uses. T�i�_i Fr" wd_� _r'1__4 There are several pole-mounted utility transformers on the Property associated with water pumps adjacent to the irrigation sump pond near the northeast corner of the Property. The transformers are unlikely to contain PCB-based dielectric oil, although laboratory testing would be needed to confirm this. There is no oil staining or other evidence to suggest that a transformer has leaked oil that impacted the Property. There are no fuel storage tanks on the Property, nor is there record of past use of such tanks. The building site includes an employee-occupied mobile home and a storage building for farm machinery such as tractors and a sprayer. Located near the northeast corner of the building complex is a lockable cargo container. This is used to store small containers of agricultural chemicals including pesticides and herbicides. There was no staining or odor in the area of the cargo container to 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc. Phone: (209)569-0293 Modesto, CA 95356 Fax: (209)569-0295
