ATTACHMENT "B" -2- <br /> APPLICATION RQUIREMENTS <br /> GENERAL ORDER FOR <br /> STOCKTON DEEP WATER SHIP CHANNEL'S <br /> MAINTENANCE DREDGING ACTIVITIES <br /> 2. Elutriate and column settling analyses results that demonstrates the anticipated <br /> decanted dredge return water concentrations and required settling time to prevent <br /> potential impacts to receiving waters. <br /> 3. Predredge Sampling and Analysis results. The results must specify or include the <br /> following: <br /> a. Sediment sampling and analyses performed to demonstrate that the sediments <br /> are `Inert Waste'. The following must be included: <br /> (1) Location and rationale for sampling locations, <br /> (2) Quantity of samples, (one sample per 50,000 cyds in open channel and <br /> one sample of dredge materials adjacent to each marina. <br /> (3) Predredge sediment sampling and analyses must be performed to <br /> determine total and souble concentrations for the constituents listed in <br /> Section A.3, Applicability. Soluble sediment concentrations must be <br /> determined after performing the Waste Extraction Test (WET) method <br /> performed in accordance with the procedures of Title 22 Section 66700 <br /> California Code of Regulations. De-ionized (DI) water extractant can <br /> be used in place of the citrate acid buffer solution specified in the Title <br /> 22 procedure. The pH, total dissolved solids, and electrical <br /> conductivity measurements must also be made of the extracted solution <br /> after performing the WET procedure. <br /> (4) Test method and procedure used for each measurement/analysis, <br /> (5) Detection and reporting limits for each analysis method. <br /> (6) Sample collection technique, i.e., grabbed using clam shell excavator, <br /> suction dredge, hand sampled using a drive sampler, etc., <br /> (7) Samples collected from contiguous channel areas to be dredged can be <br /> composited to form one composite per 100,000 cyds of dredge <br /> material. Samples collected adjacent to marinas must be analyzed <br /> individually. <br /> (8) Quality Assurance/Quality Control performed. <br /> D. Dredge Material Disposal Site <br /> 1. Name and location of DMD site <br />
