Rinse the pump and tubing with deionized water to flush out the tap water and <br /> solvent residue, as applicable. <br /> 11. Drain residual deionized water to the extent possible. <br /> 12.Allow components to air dry. <br /> 13. For submersible bladder pumps, disassemble the pump and wash the internal <br /> components with soap and water, rinse with tap (potable) water, isopropanol (if <br /> necessary), and deionized water, and allow to air dry. <br /> 14.Wrap pump and tubing in aluminum foil or a clean plastic bag for storage. <br /> 15. Containerize the decontamination wash waters for proper disposal. <br /> 3.0 Investigation-Derived Waste <br /> Investigation-derived waste (IDW) can include disposable single-use PPE and sampling <br /> equipment, soil cuttings, and decontamination wash waters and sediments. Requirements <br /> for waste storage may differ from one facility to the next. Facility-specific directions for <br /> waste storage will be provided in project- specific documents (e.g., Uniform Federal Policy <br /> Quality Assurance Project Plan), or separate direction will be provided by the project <br /> manager. The following guidelines are provided for general use: <br /> 1. Assume that all IDW generated from decontamination activities contains the <br /> hazardous chemicals associated with the site unless there are analytical or other <br /> data to the contrary.Waste solution volumes could vary from a few gallons to <br /> several hundred gallons in cases where large equipment required cleaning. <br /> 2. Containerized waste rinse solutions are best stored in 5-gallon buckets or 55-gallon <br /> drums (bung-top for liquids and open-top for soils/solids) or equivalent containers <br /> that can be sealed until ultimate disposal at an approved facility. <br /> 3. Label IDW storage containers with the facility name and address, date, contents, <br /> company generating the waste, and an emergency contact name and phone number. <br /> 4. Temporarily store the IDW in a protected area that provides access to the <br /> containers and allows for spill/leak monitoring, sampling of containers, and <br /> removal following determination of the disposal method. <br />
