METAL FINISHING SOLUTIONS, INC. <br /> SAMPLING PROCEDURES <br /> Sampling and management of samples will be in accordance with Title 22, California Code of <br /> Regulations, Section 66261.20(c), which references "Test Methods for <br /> Evaluating Solid Waste, Physical/Chemical Methods", SW-846, 3rd edition, 1986, U.S. Environmental <br /> Protection Agency. In addition to the sampling methods in chapter nine of SW-846, the Department will <br /> consider samples obtained using any of the other applicable sampling methods specified in Appendix I of <br /> this chapter to be representative samples. <br /> All samples will be taken with the proper protective clothing and apparatus. Protective clothing will <br /> include at a minimum eye protection and rubber gloves. Samples will be taken only by staff members <br /> or third-party technicians that are trained in the proper sample handling methods. <br /> Both grab and composite samples will be taken as needed. All samples shall provide a true <br /> representation of the material being sampled. If a single grab sample is taken the solution or solid shall <br /> be thoroughly mixed before sampling. If a composite sample is taken equal amounts of material shall be <br /> taken from each area of the sample source. If the composite sample is being taken over time, then the <br /> sampling should be spread evenly over the total time period. <br /> New clean containers will be used for each sample. These sample containers are usually provided by the <br /> testing laboratory. The sample containers will have any required preservative in the bottle. Sample <br /> containers for metal analysis will have 1 ml of nitric acid in the container. Glass vials will be provided for <br /> organic analyses. These vials should be filled completely to prevent any entrapment of air in the vial. <br /> Each sample container will be labeled with the following information: <br /> 1. Sample ID <br /> 2. Sample date and time <br /> 3. Sampler's name <br /> 4. Analyses required <br /> 5. Preservation (if any) <br /> All samples will be accompanied by a chain-of-custody form that is usually provided by the testing <br /> laboratory. An example chain-of-custody form is attached. The chain-of custody form will be completely <br /> filled out and will remain with the samples until they are delivered to the laboratory for analysis. The <br /> identification of each sample and the samples' required analyses will be clearly listed on the chain-of- <br /> custody form. <br /> All samples will be transferred to the testing laboratory in an ice chest. Sufficient ice will be provided in <br /> the ice chest to maintain the temperature of the samples at 40 <br /> Centigrade or less until the samples are delivered to the testing laboratory. All samples will be analyzed <br /> by a testing laboratory that is certified by the State of California. <br /> Each hazardous waste generated at Metal Finishing Solutions, Inc. as shown in Exhibit 1 will be analyzed <br /> 1325 EI Pinal Drive Stockton,CA 95205 Tel (209)798-9328 <br />
