II�01 <br /> ' GEOMATRIX <br /> analyses will be performed by Precision Enviro-Tech (PET), the Port's contracted analytical <br /> laboratory in Stockton, and McClelland Laboratories, Inc. (McClelland), in Sparks, Nevada. <br /> ' 2.1 TASK 1: EVALUATION OF DISPOSAL PLACEMENT SITE CAPACITY <br /> In order to determine the adequacy of the DPS for accepting the volume of dredged material, <br /> ' Geomatrix will work with Port maintenance staff in determining the anticipated storage <br /> capacity of the 40-acre DPS prior to beginning the dredging in the fall of 2002. Geomatrix will <br /> estimate the volume of solids and liquids that will be contained in the 400,000 cubic yards of <br /> dredged material and then evaluate alternatives for disposal of the water that drains from the <br /> dredged material. Drainage water disposal options to be evaluated include reuse, land disposal, <br /> and return to the river. The evaluation of options will consider volume and quality of water <br /> generated by the dredge materials. <br /> The deliverable for this task will be a written summary documenting the anticipated storage <br /> capacity of the DPS and drainage water disposal options. <br /> 2.2 TASK 2: EVALUATION OF VIBRA-CORE SEDIMENT SAMPLES <br /> ' As a basis for evaluating disposal of the dredged material, Geomatrix will evaluate laboratory <br /> analytical results of sediment samples collected by Port staff. It is our understanding the <br /> sediment samples will be submitted to PET for analysis of: <br /> • CAM 17 Metals, Total and Soluble <br /> • Semi-Volatile Organic Compounds <br /> • Volatile Organic Compounds <br /> • Organo-chlorine Pesticides <br /> • Organo-phosphate Pesticides <br /> 9 Polychlorinated Biphenyls <br /> ' • Dioxins <br /> • Total Extractable Petroleum Hydrocarbons <br /> • Total Purgeable Petroleum Hydrocarbons <br /> • Oil & Grease <br /> ' I:\PROJEC A6000s\6988.000\6988-IO.doc 2 <br />
