The second i formational gathering source is the Environmental Questionnaire found in Appendix . This documents environmental information from Mrs. May Slikker. As the owner a is knowledgeable of activities that have taken place on the subject property for ast 62 years (1945 to 2007). The third informational source is the Geotracker Site Lift from the State Water Resources Control Board for underground (USTs) and leaking underground fuel tanks (LUFTs). No USTs or LUFTs were noted on the Geotracker Site List. The fourth informational source is the2 3 Groundwater Lines of Equal Dep/and ' Elevation Maps found ppendix E i11 tratmg the depth and directional flow of the underlying groundwater. The depth ' pproximately 35 ft MSL. Groundwater flow direction appears to be slightly in a northerly direction. § 3.2 Description of all past on-site potential and/or known above and below ground sources of contamination identified at the project site would include nitrate, PCBs from electrical transformers, and agrichemical residues. As referenced, there w no testing of any portion of the property. There is an extremely slight potential of DDT residual insecticide from farming operations that may have taken place on the property decades ago, although this is somewhat improbable and inconsequential. Residual pesticide is inconsequential in my professional opinion because the vast majority of the property will remain in agricultural production. § 3.3 Description of all current on-site potential and/or known aand below ground sources of contamination identified at the project site include: No sours s of current observable above-ground contamination. Subsurface cont may be possible from the referenced sources, in addition to the on-site septic tank/leachfields, although this may be considered slight. Three, older electrical transformers are on the property, as illustrated in the attached photographs. These transformers may contain polychloride biphenyls (PCBs). If there was a leak or explosion, it would be the responsibility of the transformer owner to mitigate contamination. <-- § 3.4 Description of all past off-site potential and/or known above and below ground sources of contamination identified in the area of the project site that has or may impact the project site includes: Information conveyed by the March 8, 2007 Envisions Program Documents illustr no list* gs on or in proximity to the subject roperty. The two closest Leaking Under el Tanks (LUFTs) are approximat y four miles the east and four miles to the northwest, which can both be considered cross the subject property. These tanks and any leaking contents could not affect the property due to the distances involved. Page -4- Chesney Consulting
