Case #19093, Sara <br />Lee 2651 South Airport Way, Stockton <br />Paul: <br />I did review your letter dated June 18, 2009, and I met with Nuel Henderson, PG, on June 30, 2009, to <br />discuss the sampling reduction schedule proposed by PSC. I drafted a letter on July 1, 1009, based on <br />discussions during the meeting with Nuel. Unfortunately, Nuel has been sick and is currently on vacation <br />until July 13, 2009, so he has not reviewed the contents of the letter yet. <br />I can tell you that our department approves the proposed sampling schedule presented by PSC with the <br />condition that MW-4.and MW -8 be included in the annual sampling event scheduled for the second quarter <br />of each year. <br />The letter also concurs with the recommendation presented by PSC to conduct a soil vapor evaluation. <br />To address concerns that contamination detected in grab groundwater samples collected at 120 - 125 feet <br />below ground surface may be the result of "carry -down" from the sampler, our department is <br />7/10/2009 <br />
