Two electrical transformers exist: one near Mr. Inman's residence and one near Mr. Silva's residence <br /> on proposed Parcel 2. The transformer on the south side of property near Parcel 2 appears to be <br /> relatively new. The transformer near Mr. Inman's residence appears to be much older. It is unknown <br /> if this transformer contains polychloride biphenyls (PCBs). Although no indication was noted of <br /> external oil leakage, if there was a leak or explosion, it would be the responsibility of the transformer <br /> owner to mitigate environmental contamination. <br /> V. APPLIED AGRICULTURAL PESTICIDE DOCUMENTATION <br /> The only agrichemical applied to the subject property is the herbicide RoundUp®, and is done with <br /> a hand sprayer. Consequently, drift would be at an absolute minimum. Environmental Fate Data <br /> for this material used on the property was obtained from the U.C. Davis and Oregon State <br /> University Extoxnet System and is found in Appendix E. The Fate Data indicates RoundUp has a <br /> comparatively short half-life. <br /> Although DDT was banned in 1972, its presence in San Joaquin Valley soils is indicative of its long <br /> half-life of 15.6 years. Consequently, there may be extremely small concentrations of DDT, and its <br /> degradates in the subject property soils. <br /> The following chart summarizes the available Environmental Fate Data for RoundUp® that has <br /> been applied to the subject property. Noted times of duration are maximum values observed. The <br /> Fate Data is highly specific for various environmental conditions, and is normally expressed as <br /> half-lives in terms of days. <br /> PESTICIDE APPLIED TYPE SOIL WATER <br /> TO THE PROPERTY PERSISTENCE PERSISTENCE <br /> (Common Name) <br /> Glyphosate Herbicide I - 174 days 12 - 70 days <br /> (RoundUp(N) <br /> The predominate wind direction through the region is east-southeast. West-northwest, or <br /> upgradient wind shed is composed of agricultural production land including pasture, dairies and <br /> orchards. This wind direction, along with the fact that agrichemicals cannot be applied during <br /> windy conditions, ensure that the likelihood of impact to the property from unintended pesticide <br /> drift is somewhat unlikely. <br /> i <br /> 5 <br /> Chesney Consulting <br />
