Investigation-Derived Waste Management Standard Operating Procedure SWE-FSOP-802;Revision 0 Ahtna Southwest Environmental Operations and other IDW sources may be permissible to fill the drums but should be confirmed in advance with the PL or FTL. Ask the FTL whether potentially hazardous liquids should be segregated from non-hazardous. When drums or containers are full or daily activities are completed,the drum lids and rings will be fastened. Full drums or containers will be transported to the designated IDW accumulation area regularly to avoid accumulating drums or containers at investigation sites for extended periods.All drums or containers will be labeled appropriately at the end of each day's activities. Perform waste profiling before disposal (Section 4.5). Each project may have unique requirements for waste profiling, storage, and disposal—review project-specific plans and coordinate activities with the PL or FTL. 4.4 PPE and Other Consumable Supplies Inspect equipment and PPE (e.g., plastic sheets, screens, coveralls, boot covers, or other)to determine proper disposal procedures. If there is no evidence of contamination, materials can be disposed of with regular trash. Decontaminate and discard PPE and other used supplies in plastic bags and sealed in metal barrels for final storage, transport, and disposal. Decontamination procedures consist of brushing off or using small amounts of water to scrub off potential gross contamination (see SWE-FSOP-801, Equipment Decontamination). 4.5 Waste Profiling Waste profiling requirements will be coordinated by the PL with the client and disposal facility. At a minimum, a representative sample of the solid and aqueous IDW will be collected and analyzed for all chemicals of potential concern. When approved by the PL, generator knowledge is an acceptable alternative to laboratory testing. The PL will also coordinate with the client, disposal facility, and waste transporter to manage the completion of the waste manifest and ensure that an adequate number of manifests are available for the amounts and types of material to be disposed of.An example manifest is provided in Attachment 1. Waste manifests are signed by the client or client's representative (usually identified on the manifest as the "owner" and/or"generator"). Field personnel are not allowed to sign manifests under any circumstances. 4.6 Labeling Apply a label immediately after adding soil or groundwater to drums or soil to bins. If the waste generated has not been profiled, apply a "Pending Analysis" label (Figure 1).Add the contents, date(s) of generation,the origin of materials, address of generation, and contact information to the label. Because drum and container labels may be exposed to the elements, it is essential to use waterproof markers to fill in the information on labels and possibly clear packaging tape over the labels to preserve the information. Once the material has been profiled, remove the "Pending Analysis" label and add the appropriate "Non-Hazardous" (Figure 2) or"Hazardous" label (Figure 3).Add the shipper, address, date(s) of generation, contents, and contact information to the label.
