Ms: Mary_Meays f _ Page 3 <br /> June 8, 1993 <br /> i <br /> (3) No'TPH-G or,xylenes were-detected.in_ the samP Y <br /> les which were analyzed <br /> during-this investigation TPH-G and xylenes were previously <br /> documented in'-the'-sample-obtained from the soil.pile du <br /> ring excavation <br /> of the.iinidergrouhd storage:tank in August-1991. The 1ev ls, of TPH-G and <br />{ kylenes�in the.sample-were 1,200 and 2.4 mg/k9. <br /> "respectively. -Itis highly <br /> likely:that-the-gasd_line and xylenes volatilized-despite the fact-that the soil <br /> -pile-was covered-with_plastic. -At 'the time of sample collection,the pile <br /> had been sitting at-the site-for five months,-and1t is impossible-to create a <br /> seal-with the-plastic-'to prevent volatiliza#ion of'the gasoline and xylenes. <br /> ERM-West:concludes that the sampling and.analysis which was conducted . <br /> provides information that is -representative-of thechemical characteristics of <br /> the stockpiled soils•at the ,site. . The-data-indicate_that:no environmental or <br /> health threat is posed'bythe-soils. _Given the addition_a1 lapse of time-since <br /> 'the sampling-in-January 1992, it is very likely that.all constituent . <br /> coricentrations.are- non=detect:---�Thi;is, .ERM-West recommends that the soils <br /> be spread out in open -areas.-and mixed.with-o.ther.clean soils located on the <br /> Catellus property. To treat or handle the soils=in-a more complicated manner <br /> is inappropriate.and-would.add-needless..expense,fo Catellus.-We would like <br /> to-schedule.this activity within the next-few weeks.: <br /> We hope that-this letter sufficiently addresses--your concerns, and we look <br /> forward to your response on this matter..
