Turner Road <br /> December 9, 1488_- Page 2 of 2__ Lodi, CA <br /> 5. Laboratory that will collect soil samples: Canonie Environmental (209) 983-1340 <br /> A signed "Release of Information Authorization" is attached. <br /> 6. Remediation Steps: We propose to enlarge the excavation to approximately 75' wide <br /> x 100' long x 40' deep -first by removing approximately 20 feet of overlay of clean <br /> soil, approx. 2,780 cubic yards, and stockpiling it on site. Then we shall excavate <br /> in three (3) foot drops downward and outward toward the monitoring wells until no <br /> more contamination is visible and no odor is present. <br /> This excavated soil will be stockpiled on site an plastic and covered. It is <br /> anticipated that excavating will remove all contaminated soil from, in and around <br /> the excavated area. <br /> We will call your office to set a date for sampling, giving at least 48 hours <br /> notice. <br /> We plan to take one bottom sample from the center of the excavated area and one <br /> sample from each of the side walls. We will request a 24 hour turnaround on these <br /> samples. There will be a.maximum of 5,555`cubic-yards`of soil excavated and this <br /> will be tested at a rate of 2 samples per 50 cubic yards. We will be prepared to <br /> take as many samples as the health District deems necessary. We will test for BTX & E <br /> and TEPH. <br /> Contaminated soil is to be treated on site at a later date by bio-rtnediation <br /> and aeration. Aeration would be under permits, guidelines, and direction of the <br /> San Joaugin County Air Pollution Department. <br /> 7. Timing: Sampling could be scheduled within 48 hours following your review of this <br /> work plan. The sample analysis from the hole and side walls should be ready for your <br /> review within 48 hours,and the analysis from the stockpile samples should be ready <br /> within two weeks, after they have been taken. <br /> We are willing to pay any overtime costs to expedite review of this work plan <br /> as we wish to conclude this matter this month. <br />
