Thirty-nine drums of waste soil and <br /> waste water are currently stored on site. <br /> The waste water drums will be combined and representative samples will be collected in 40 <br /> milliliter vials and 1 liter amber jars for analysis to verify that the contents meet the criteria of <br /> the City of Stockton Department of Municipal Utilities for discharge into the sanitary sewer <br /> system. The water samples which will be collected will be laboratory composited 2:1. If this <br /> will meet the testing requirements of the City of Stockton, the water sampling as proposed is <br /> approved. <br /> The waste soil drums are proposed to be characterized by selecting twelve drums randomly <br /> to collect samples that will be stored in clean 4 ounce wide mouth glass jars. The samples <br /> v4H-"collected will be laboratory composited 4:1. Soil samples should be collected from <br /> each distinct waste unit, in this case each drum. Generally, soil samples are collected in <br /> brass sleeves rather than wide mouth glass jars. When sampling soil, attempts are made to <br /> collect the most undisturbed soil samples as possible. Please collect soil samples using brass <br /> sleeves. Also, the work plan indicated that the soil will be disposed of at Forward Landfill. <br /> Please verify their characterization requirements, as soil results obtained from samples <br /> collected during drilling may sometimes be used for characterization purposes. <br /> Furthermore, depending how the soil is proposed for transport to the landfill, it may be less <br /> expensive to combine the soil first and then sample the stockpiled soil. <br /> Please contact the State Water Resources Control Board to obtain pre-approval for the costs <br /> included with the work plan for work to be completed by Farr Associates and ICF Kaiser. <br /> If I can provide any further direction, please do not hesitate to contact me. <br />
