7.0 Decontamination Procedures <br /> r <br /> Decontamination will take place in the decontamination area identified on-site. A <br /> decontamination station will be set up to decontaminate sampling equipment and personnel. The <br /> `r station will include at least two 5-gallon buckets; one filled with a clean water and soap mixture <br /> and the other with clean water. A temporary decontamination pad with a rinsate collection <br /> system will be set up to decontaminate trucks and excavation equipment leaving the <br /> contamination reduction zone and to decontaminate equipment between sample locations. A <br /> r� <br /> steam cleaner will be used to decontaminate reusable drilling equipment and vehicles. <br /> All site personnel will utilize decontamination procedures that minimize,to the extent practical, <br /> the amount of wash/rinse waters generated at the Site. All workers and PPE will be <br /> decontaminated to prevent the spread of hazardous materials. All workers will wash up <br /> ` appropriately after removing PPE and prior to leaving the immediate work area and the Site. <br /> Disposable Tyvek®/cotton coveralls will not be worn off-site. <br /> Support vehicles are to be left, to the extent practical, outside of the exclusion area so that <br /> decontamination will not be necessary. All equipment that accesses off-road areas known to <br /> .� contain contaminated soil or liquid must be decontaminated before leaving the Site. All rented <br /> equipment that comes in contact with a contaminated media(soil or liquid) must be <br /> decontaminated before it is returned to the vendor. Reusable sampling equipment will be <br /> decontaminated prior to and after each use with a non-phosphate detergent(Liquinoxo) and <br /> water solution and rinsed with deionized water to prevent cross-contamination. <br /> Disposable items will be bagged for disposal. All site personnel will minimize, to the extent <br /> practical,the amount of disposable waste generated at the Site. All disposable sampling <br /> equipment will be rinsed with water and managed as non-hazardous waste. Rinsate from <br /> +v <br /> decontamination will be collected and stored on-site in 55-gallon drums or a portable <br /> polyethylene tank. <br /> All soil material will be drummed for short-term containment on-site, sampled and labeled as <br /> waste unless otherwise determined to be non-hazardous based on the laboratory results. All <br /> wastes will be properly managed and disposed by the Company. <br /> w <br /> wcDP-N:ICons Ii g%,i i.S—,AProject L-J71778407.—d— 7-1 <br /> 12IWo <br /> v <br />
