3.3 Description of All Current On-Site Potential and/or Known Above and Below Ground Sources of Contamination Identified at the Project Site: Presently, there are no underground storage tanks on the property and visual inspection did not produce any evidence of buried containers, as well as no odors that would be associated with buried chemical tanks. There are three above ground fuel tanks on the site which are permitted under the San Joaquin Valley Air Pollution Control District. On-site water dissipates through either percolation or evaporation via an on site retention pond. Stormwater flows through a sand and oil separator prior to flowing into the pond. 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: Past off-site potential for contamination is low. The subject parcel is located in an agricultural neighborhood. The land use has historically been used as a residence and for agricultural purposes. 3.5 Description of all Present Off-Site Potential and/or Known Above and Below Ground Sources of Contamination Identified in the Area of the Project Site: Present off-site potential for contamination is low. (See Appendix for case studies.) 4.0 EVALUATION OF PAST AND CURRENT SOURCES OF CONTAMINATION IDENTIFIED AT OR NEAR THE SITE AND RECOMMENDATIONS FOR FURTHER ACTION: 4.1 Evaluation of each potential and/or known source of contamination identified for any real and/or potential threat to human health and the environment: The depth to ground water in this area is approximately 110 feet. Due to this depth, any pesticides, insecticides, and fertilizers used on the property in the past or present would have a minimal impact to the ground water. All existing and future homesibuildings will be served by private wells. 5.0 CONCLUSIONS AND RECOMMENDATIONS SECTION: 5.1 Discussion of the Above Evaluation: There are fuel storage tanks on this site that are permitted through the San Joaquin Valley Air Pollution Control District. Thus the potential for contamination is low. There are pesticides, insecticides, and fertilizers used on the site but the depth to groundwater is such that the impact is minimal. No mitigation measures are recommended. 5.2 The Report is inclusive: All information in this report does not reference any other documents that are not contained in this report. 5.3 Report was signed dated and stamped: See below. 5.4 'Che report was prepared within Six Months of the Date of the Subm i ttal: This report was originally generated in February, 2024. 5.5 "Che Attachment/Appendices Contain Sufficient Documentation to Support Claims Made in Report: See Appendix. 2
