The predominate wind direction through the region is to the east-southeast. West-northwest, i <br /> or upgradient wind shed comes through the Altamont Pass and not over agricultural <br /> production land. <br /> i <br /> Although DDT was banned in 1972, its presence in San Joaquin Valley soils is an indication <br /> of its long half-life. Consequently,there may be extremely small concentrations of DDT <br /> and its degradates in the property soils from farming operations that may have taken place <br /> on the property decades ago. Any minute residual pesticide concentrations are <br /> inconsequential. <br /> §3.3 Description of all current on-site potential and/or known above ground and below ground <br /> sources of contamination identified at the project site are included in Section 3.2. No <br /> sources of current aboveground contamination were observed, other than the referenced <br /> items. <br /> Subsurface contamination of known or unknown contaminants may be possible,particularly <br /> naturally occurring nitrate concentrations, as referenced. <br /> §3.4 Description of all past off-site potential and/or known above and below ground sources of <br /> UP <br /> contamination identified in the area of the project site that could impact the site include: <br /> Information conveyed by the ERS documents indicate no listings,with an almost impossible R. <br /> likelihood of impact to the property from a distant contaminated site. The GeoTracker <br /> document illustrates no listings on the property or within a one-half mile radius from the <br /> property. There are no Leaking Underground Fuel Tanks (LUFT). <br /> Agricultural spray drift affecting the property from the nearest agricultural production land QV <br /> \couTd--Fe an extremely slight possibility, since agricultural production occurs to the <br /> northeast. Consequently,the wind would have to blow toward the southwest,which is rare. <br /> §3.5 Descriptions of all current off-site potential and/or known above and below ground sources <br /> of contamination identified in the area of the project site include those referenced in <br /> Sections 3.2, 3.3, and 3.4 above. Any contaminated sites can be considered"past" off-site <br /> sources of contamination that are simultaneously"current" contaminated sources. <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 in the above <br /> Sections have been discussed in the respective Sections to facilitate the transfer of <br /> information to the reader. <br /> Chesney Consulting <br />
