0 0 <br /> Thank you for looking at the Work Plan so quickly. I will amend it accordingly and resubmit. Do I <br /> resubmit the Site Mitigation Fee as well? <br /> I also want to check if we can perform the drilling and soil sampling ourselves under your oversight?The <br /> laboratory samples would be picked up directly by the lab, McCampbell Analytical, Inc.We can schedule <br /> the pickup after sampling is finished while EHD is still present. <br /> Sincerely, <br /> NEIL O.ANDERSON&ASSOCJATES,INC. <br /> HeatherShaddox <br /> Staff Geologist <br /> 209.367.3701 <br /> Fax 209.333.8303 <br /> 902 Industrial Way • Lodi, CA 95240 <br /> <Image001.9If>C0NFIDENTIALITY NOTICE: This communication and any accompanying document(s)are confidential and <br /> privileged.

Anderson &Associates, Waste Water Disposal System <br /> Hi Heather, <br /> I'm reviewing section 3.2 of your work plan that proposes drilling two borings 5 feet away from the <br /> "drywell". This is not acceptable,as it does not meet with the US EPA guidance document. The dry <br /> wells are to be over drilled and a soil sample collected in the middle of each well at 1-2 feet below the <br /> bottom of the well (at 41-42' bgs) and a second sample collected 5 feet bgs (at 45' bgs). This should <br /> place you into groundwater, if the water table has dropped to that depth. Recent 2012 San Joaquin <br /> County Flood Control and Water Conservation District Groundwater reported groundwater at 30-40 bgs <br /> at your site. If groundwater has dropped below that depth,then continue drilling through the borehole, <br /> collecting soil samples every five feet, until groundwater is encountered to collect the water samples. If <br /> groundwater is above 40 bgs,then collect the water samples first before the well is over drilled. <br /> Section 3.2.2 is acceptable to collect sludge samples from the drain that runs to the "dry wells" and soil <br /> samples 1.5 feet below the drain,as described. <br /> If you are unable to perform the work according to the US EPA Guidance document as I describe above, <br /> then I will have to refer this case to Regional Board for their oversight on this project. Please submit a <br /> revised work plan or indicate that the proposed work cannot be done according to US EPA methods. <br /> Thank you, <br /> Adrienne <br /> Adrienne Ellsaesser, REH5 <br /> Program Coordinator <br /> San Joaquin County <br /> 3 <br />
