I <br /> v .1 <br /> i <br /> 6 November 18, 2004 <br /> NOA Project Number: E04130A <br /> Ldrains into Goose Creek. <br /> One paved road crosses the northern portion of the subject property. There was a dirt access road <br /> surrounding the vineyard, and another dirt road that ran from the northeastern corner of the <br /> property to the paved road. <br /> There was a pole barn on the property that houses the 1,000 gallon above ground fuel tank,water <br /> 6. filters and the well.The structure has no heating or cooling system. The above grrpund fuel tank was <br /> observed to be within a catch basin. No staining or odors were observed near the fuel tank. <br /> Another above ground storage tank was observed on the eastern edge of the property. It was <br /> located within secondary containment. No staining or odors were observed, near the fuel tank. <br /> 6. No transformers were observed on or near the property. <br /> Surrounding properties were surveyed at the time of the site reconnaissance. To the north of the <br /> L subject property the land was used as a vineyard. To the west the land was bare grassland. To the <br /> east the land was used as an orchard. The land to the south was bare land with a few agricultural <br /> related structures. <br /> L <br /> /3.2 3.2 Past On-Site Sources of Contamination <br /> LNo potential above-or below-ground on-site potential or known sources of contamination were <br /> identified from past uses of the site, except for the following: <br /> L Because of past agricultural use, there is possible petroleum contamination from fueling and <br /> spilling of the tank, and possible agricultural chemical contamination due to chemical mixing <br /> Land application. <br /> • Paraquat, a Restricted Use Pesticide in EPA toxicity class I (highly toxic),with a half-life in <br /> soil of greater than 1,000 days,was applied to the vineyards in 2002. <br /> O 3.3 Current On-Site Sources of Contamination <br /> ` No above- or below-ground on-site potential or known sources of contamination were identified <br /> from current uses of the site, except for the following: <br /> LThe above-ground storage tanks may possibly cause contamination during tank fueling or <br /> spillage from over filling,though it is unlikely because both tanks are located in secondary <br /> t containment. <br /> L <br /> • Because of past agricultural use, there is possible petroleum contamination from fueling and <br /> spilling of the tank, and possible agricultural chemical contamination due to chemical mixing <br /> V <br /> 7 <br />
