Eric Vielhauer <br /> CA Dept. of Fish and Game <br /> 1701 Nimbus Road <br /> Rancho Cordova, CA 95670 <br /> Subject: Workplan for Soil Excavation <br /> Marina West Marine Services, 6651 Embarcadero Dr., Stockton, CA <br /> Dear Lt. Vielhauer: <br /> Enclosed is your copy of our Workplan for the subject facility. As we recently discussed over <br /> the phone, a small of area of surface soil on the top of the levee contains elevated concentrations <br /> of copper due to the presence of paint chips from boat cleaning. Our recent sampling suggests <br /> that contamination is not present on the bank of the levee. <br /> Our Workplan proposes to excavate about 3 inches of soil from the top of the levee and dispose <br /> of the material at a Class I landfill. It is important that this soil be removed before the fall rains <br /> begin so that copper-contaminated soil doesn't wash over the levee. It is my opinion having <br /> inspected the area, that the excavation will not impact the bank of the levee and therefore a <br /> Section 1603 notice is not needed. Would you please review our Workplan and let us know as <br /> soon as you can if the proposed work meets with your approval? <br /> If you need any additional information please contact me at your earliest convenience. <br /> Respectfully, <br /> Ground Zero Analys� Inc. <br /> Gregory P. Stahl, RG 5023 <br /> CA Certified Hydrogeologist No. 264 <br /> Enclosure <br />
