1i r <br /> Y • n <br /> C) <br /> 3.2 Description of All Past On-Site Potential and/or Known Above and Below Ground <br /> Sources of Contamination Identified at the Project Site: Past on-site potentials for <br /> contamination are low. The property has been used for agricultural purposes for more than 10 <br /> years. Historically the orchards have been treated with Sevin, Chloropicrin, Methyl Bromide, <br /> Aluminum Phosphide and strychnine to name a few of the chemicals used. (See permit number <br /> 39-07-3900090 for all pesticides used at the project site, located in Appendix). Historically <br /> there have been no underground storage tanks. The owner has no knowledge of above ground <br /> storage of chemicals on the subject parcel. The Calaveras River runs along the south boundary <br /> of subject parcel. <br /> 3.3 Description of All Current On-Site Potential and/or Known Above and Below <br /> Ground Sources of Contamination Identified at the Project Site: Presently there are no <br /> underground storage tanks on the property and visual inspection did not produce any evidence <br /> of buried containers, as well as no odors that would be associated with buried chemical tanks. <br /> There are no storage tanks above ground. There are no above ground fuel tanks on the site. <br /> On-site storm water is contained on -site and dissipates through either percolation or <br /> evaporation. <br /> 3.4 Description of All Past Off-Site Potential and/or Known Above and Below Ground <br /> Sources of Contamination Identified in the Area of the Project Site: Past off-site potential <br /> for contamination is low. The subject parcel is located in agricultural community. <br /> 3.5 Description of all Present Off-Site Potential and/or Known Above and Below <br /> Ground Sources of Contamination Identified in the Area of the Project Site: Present off- <br /> site potential for contamination is low. There is no knowledge of below ground sources of <br /> contamination in the area of the project site that has or may impact the project site. <br /> 4.0 EVALUATION OF PAST AND CURRENT SOURCES OF <br /> CONTAMINATION IDENTIFIED AT OR NEAR THE SITE AND <br /> RECOMMENDATIONS FOR FURTHER ACTION: <br /> 4.1 Evaluation of Each Potential and/or Known Source of Contamination Identified for <br /> any Real and/or Potential Threat to Human Health and the Environment: The depth to <br /> ground water in this area is a roximatel 1 Due to this depth, any pesticides, <br /> insecticides, and fertilizers used on the property in the past or present would have a minimal <br /> impact to the ground water. <br /> 5.0 CONCLUSIONS AND RECOMMENDATIONS SECTION: <br /> 5.1 Discussion of the Above Evaluation: There are no chemical containers for fuel storage <br /> tanks on this site; thus the potential for contamination is Iow. As was stated above, any <br /> pesticides, insecticides, and fertilizers used on the site do not pose any significant potential for <br /> contamination to the project site, and no mitigation measures are recommended. <br /> t <br /> 2 <br /> c:107431Surface and Subsurface June, 2007 <br />
