The second informational gathering source is the Environmental Questionnaire found in Appendix B. This documents environmental information from the current owner, Mr. Terry Davis. As the owner, he is knowledgeable of activities that have taken place on the subject property for the past 20 years. The third informational source is the Geotracker Site List from the State Water Resources Control Board for underground (USTs) and leaking underground storage tanks (LUSTs). The fourth informational source is the 2003 Groundwater-1;J s of Equal Depth and Elevation Maps found in Appendix E illustrating the depthand directional flow of the underlying groundwater. The depth is approximately 22 ft L. Groundwater flow direction appears to be slightly in a north-northwesterly-&rection. § 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 lead paint (due to the age of the residential structure) and asbestos. As referenced, there was no testing of any of the on-site structures. However, I personally witnessed the destruction of the residential structure and asbestos removal protocol was used. A destruction permit for the referenced septic tank and leachfietd-thiat-served the house was taken out on September 12, 2006 (SR 48158) to satisfy,Condition"E"on the Conditions of Approval. However, EHD records indicate that no inspection of the septic system destruction was ever done. In addition, the domestic*ell-still-exists and is isolated from construction activities. It is known that the well opening is sealed with a steel cover that has been welded to the casing. 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 be covered with impermeable surfaces of asphalt, concrete and buildings. This will prevent fugitive dust that may contain residues from escaping the soil surface. § 3.3 Description of all current on-site potential and/or known above ground and below ground sources of contamination identified at the project site include: No sources of current observable above-ground contamination. Subsurface contamination may be possible from / the referenced sources, namely the septic tank/leachfield and residual pesticides. No electrical transformers are on the property; however, there are surrounding transformers. These transformers appear to be relatively new and unlikely to contain polychloride biphenyls (PCBs). If there was a leak or explosion, it would be the responsibility of the transformer owner to mitigate contamination. Page-4- Chesney Consulting
