An electrical transformer is found on a pole at the north side of the property, next to the water <br /> well. It appears that a relatively small oil leak has developed on the underside of the <br /> transformers. It is the responsibility of the transformer owner to mitigate any environmental <br /> contamination that may occur from this leaking oil. <br /> From previous nitrate loading and soil suitability studies done to the west, it is known that there <br /> can be higher concentrations of nitrate in the underlying water aquifers, due to agricultural <br /> inputs. However, nitrate impact is unknown under the property, which will be determined in the <br /> Soil Suitability Study. <br /> As noted on the attached Environmental Questionnaire, calcium ammonium nitrate was applied <br /> to the soil in 1991 or 1992, and urea ammonium nitrate 32% (UAN32) was applied foliarly at <br /> about five lbs. per acre (5 units). According to the Western Fertilizer Handbook published by the <br /> California Fertilizer Association, 200 pounds per acre are required of mature almond trees to <br /> produce an acceptable crop. Since there is organic material in the soil to provide an Estimated <br /> Nitrogen Release (ENR) that would supplement the applied N units, the applied units of nitrogen <br /> appears to be within the recommended guidelines. <br /> PUBLIC ENVIRONMENTAL RECORD/DATA SOURCES <br /> Static groundwater is found approximately 65 feet under the property as illustrated on the attached <br /> 1999 Lines of Equal Depth to Groundwater map. From the 1999 Lines of Equal Elevation of <br /> Groundwater, the groundwater directional flow is toward the northwest. A groundwater depth of <br /> 65 feet can be considered a medium depth groundwater elevation which is not easily impacted <br /> from serious point source releases and to a somewhat lesser degree from agrichemicals such as <br /> pesticides, herbicides, or nitrates from fertilizers. The degree of impact from agrichemicals is <br /> particularly mitigated when there are intervening layers of clay or hardpan soil down to the static <br /> water table depth. It is known that hardpan strata exists in this locale. <br /> No records of above ground, or under ground (AST/UST) storage tanks exist for the subject <br /> property address. This is also illustrated on the attached GeoTracker Site Map, which shows no <br /> tanks near the site. A Leaking Underground Fuel Tank (LUFT) site is shown at the very north edge <br /> of the map and is approximately two miles to the northwest of the subject property. This LUFT is <br /> downgradient to the site. Potential environmental impacts from past, present or future facilities <br /> within a one mile radius is unknown at this time, but highly unlikely. <br /> Two sources of information which attempt to document and define on-site and surrounding past land <br /> use were also utilized. The first is the use of aerial photographs. Aerial photographs of the subject <br /> area from 1970 through 1977 found on USDA Soil Maps reveal the property to be farmed differently <br /> than it has been in the recent past. The aerial photo shows that there appears to be only the referenced <br /> buildings on the property. The USDA Soil Map shows the soil to consist predominately of a Veritas <br /> fine sandy loam (#266). Typically, these soil types are well drained with moderate permeability, <br /> which is a beneficial soil attribute for septic effluent management. There are sufficient soil "fines" to <br /> impede rapid percolation so treatment of effluent can occur before reaching the water table, unlike <br /> Page -3- <br /> Chesney Consu£tin8 <br />
