200 North Beckman <br /> Page 2 <br /> i' <br /> The estimated extent of impacted soil, Figure 3, indicatA' that'soil contamination is not <br /> expected to be found approximately 6 feet from SB-2. Based on soil sample results from <br />` SB-2 and BH31, located approximately 10 feet from m SB;2, it is unlikely that the extent <br /> of soil: contamination is characterized in the estimated area of,impacted soil. <br /> t <br /> The cross-section, Figure 4, included S13-3 and SB-2. Please note that Table 1 does not <br /> reflect any documented soil contamination associated with samples collected from SB-3. <br /> Also, note that soil which is removed from a contaminated) area is required to be <br /> sampled to confirm that the soil is not contaminated. Once the recently installed tanks <br /> are removed soil samples will be required to show that the sy.;stems did not contribute <br /> to the contamination already documented at the site. Soil samples to evaluate the <br /> I effectiveness of the proposed excavation should be collected, at minimum, every 20 feet <br /> along the sidewalls and bottom of the excavation. <br /> Enclosed is an application to remove underground storage tanks which should be <br /> submitted and approved prior to the removal of underground storage tanks. Please <br /> submit with the application to remove tanks, an addendum:�addressing PHSIEHD's i <br /> comments and requirements outlined in the Underground Storage Tank Regulations. <br /> If you have any questions or comments, do not hesitate to contact Mary Meays, Senior <br /> REHS, at (209) 468-0337. <br /> �3 <br /> Donna Heran, REHS, Director <br /> i{ <br /> Environmental Health Division <br /> 1 <br /> I� 1 <br /> Mary Meays, Senior REHS Diane M.
