Substantial or <br />potentially substantial <br />adverse change <br />Yes Maybe No <br />d. The destruction, covering or <br />modification of any unique <br />geologic or physical features? X <br />e. Any increase in wind or water <br />erosion of soils, either on or <br />off the site? X <br />f. Changes in deposition or erosion <br />of beach sands, or changes in <br />siltation, deposition or erosion <br />which may modify the channel <br />of a river or stream or the bed <br />of the ocean or any bay, inlet <br />or lake? X <br />g. Exposure of people or property <br />to geologic hazards such as <br />earthquakes, landslides, <br />mudslides, ground failure, or <br />similar hazards? X <br />Explanation: There will be minor soil disruption from soil <br />sampling, during removal of the underground tank, and <br />possible excavation of contaminated material. Samples <br />will be collected with a hand auger drilled to a depth <br />of 3 feet to the concrete and soil interface. Holes <br />will be backfilled with native soil. These soils <br />would be containerized and sampled for future disposal <br />purposes. If initial soil sampling indicates any soil <br />contamination, the Plan allows removal and disposal of <br />up to to 50 cubic yards of soil, asphalt, and <br />concrete. If the results indicate more than 50 <br />yards, then the Plan identifies steps that the <br />facility must take to notify DTSC, prepare a workplan <br />to investigate and submit the workplan and schedule. <br />Future actions will require CEQA analysis of the <br />environmental impact of these propsed actions. <br />2 <br />
