in June of 2023(see appendix for SPCCP). In the past the site was used as a waste tire storage site and was in compliance when the EHD stopped regulating waste tire storage sites (see appendix for results). The state tire waste recycling database didn't yield anything regarding the storage of waste tires on site and as such yields no concern. Since the SJC EHD stopped regulating waste tires, the site temporarily stores tires on site in a designated area to be sold back to the manufacturer. The site has 5 existing septic systems of various sizes for the different buildings on site and will continue to be used in the future(see tentative map for locations in the appendix). The site was used for the storage of hazardous materials and waste including petroleum products, coolant and lead acid batteries. The hazardous materials were out of compliance but returned to compliance in 2014 per the SJC EHD(see appendix for results). The orchard historically has been treated with Carbaryl, Aluminum Phosphide, Strychnine, Zinc Phosphide, 2,4-D Amine, Paraquat and Non-Permit AG Prod. (See Permit No. 39-18-3904351 and Permit No. 39-21-3904351)(See Appendix) 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 13 above ground fuel tanks and various 55-gallon drums on the site which were brought back into compliance in 2023(see SPCCP in the appendices for sizes and contents). The site is used for the storage of hazardous materials and waste including petroleum products, coolant and lead acid batteries(see appendices for more information). The site will store waste tires on site temporarily in a designated area so that they may be sold back to the manufacturer. 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 homes/buildings will be served by the public water system that exists on site(see appendix for public water system compliance information). The potential contaminants discussed in the above sections are 2
