Open Pit Water Sampling <br />To collect a water sample from a tank excavation pit, a teflon bailer will be submerged <br />allowing water to slowly fill the bailer. If the sampling point is beyond the collector's reach, a <br />rope will be used to lower the bailer into the pit. The pit is considered a confined space. <br />Personnel will not enter the pit to take samples. <br />Chemical hazards include skin contact with contaminated soil and water and inhalation <br />and ingestion of contaminated material. <br />Personnel will wear appropriate PPE, provide air monitoring, and follow standard safety <br />' procedures to minimize hazard. <br />Physical hazards include slips, trips, and falls, heat stress and possible hazards due to the <br />close proximity to heavy equipment. There will be no confined space entry. <br />Site Closure and Finishing <br />After completing the soil excavation and sampling, the excavation pit will be backfilled <br />with clean material. <br />The tank removal will generate contaminated materials. All contaminated soils will be <br />stockpiled on plastic sheeting next to the excavation. These soil piles will be covered with plastic <br />sheeting until they are removed off-site. Tank wastes will be handled as hazardous wastes and <br />will be disposed of at an appropriate facility by the Navy. All piping, concrete, tank ballast slab, <br />tank straps and the tank will be disposed of at an appropriate facility. <br />Contaminated PPE will be removed within the work area, placed in plastic bags, and <br />stored in labelled 55 -gallon drums. These materials will be handled as hazardous wastes. <br />Decontaminated water generated through the decontamination of sampling equipment and <br />personnel decontamination will be stored in labelled 55 -gallon drums. These wastes will be <br />handled as hazardous wastes. <br />Chemical and physical hazards during these activities are identical to those described in <br />previous tasks. <br />1 A-6 <br />
