It appears that much consideration has been given in preparation of this <br /> treatment system for the cleanup of the unsaturated zone at the site. However, <br /> We have two major technical concerns which should be evaluated and the applicable <br /> designs reconsidered prior to the commencement of construction on 1 March 1991, <br /> as scheduled in the Remedial Action Plan. Our concerns involve the soil sample <br /> analyses and the depth of length of screen intervals in the monitoring tubes and <br /> wells. Enclosed is a memorandum which discusses these concerns. <br /> The design documents stated that a high strength treatment system will be <br /> constructed in Phase III of the Subsurface Soil Treatment System. Because this <br /> system will be installed prior to the five year renewal of the National Pollutant <br /> Discharge Elimination System (NPDES) permit, we require that a Report of Waste <br /> Discharge for this system be submitted four months prior to the renewal of the <br /> NPDES permit. <br /> If you have any questions, please call me at (916)361-5670. <br /> CAMILLA WILLIAMS <br /> Engineering Geologist <br /> CKW:cw <br /> Enclosure <br /> cc: Mr. Jim Austreng, Department of Health Services, Region 1 , Sacramento, <br /> Ron Valenoti , San Joaquin County Public Health Services, Stockton <br /> Mr. Tom Hickey, Black and Veatch, Kansas City, Missouri <br /> Mr. Peter Quinlan, Hargis and Associates, La Jolla <br />
