0 1 <br /> 1 <br /> ARCADIS SOP:Investigation-Derived Waste Handling and Storage 6 <br /> Rev.#:2 1 Rev Date: March 6,2009 ' <br /> • If excavating in potentially hazardous areas is possible,contingency plans <br /> should be developed to address the potential for encountering gross , <br /> contamination or non-aqueous phase liquids. <br /> • ARCADIS field personnel will be familiar and compliant with Client-specific , <br /> health and safety requirements such as Chevron's hand safety policy <br /> including the prohibition of fixed and/or folding blade knives. <br /> VI. Procedure ' <br /> Waste storage and handling procedures to be used depend upon the type of ' <br /> generated waste. For this reason, IDW should be stored in a secure location onsite in <br /> separate 55-gallon storage drums, solids can be stockpiled onsite(if non-hazardous), <br /> and purge water may be stored in polyethylene tanks.Waste materials such as broken <br /> sample bottles or equipment containers and wrappings will be stored in 55-gallon ' <br /> drums unless they were not in contact with sample media. <br /> Management of IDW ' <br /> Minimization of IDW should be considered by the Project Manager during all phases of <br /> the project. Site managers may want to consider techniques such as replacing solvent- , <br /> based cleaners with aqueous-based cleaners for decontamination of equipment, reuse <br /> of equipment(where it can be decontaminated), limitation of traffic between exclusion <br /> and support zones, and drilling methods and sampling techniques that generate little ' <br /> waste.Alternative drilling and subsurface sampling methods may include the use of <br /> small diameter boreholes, as well as borehole testing methods such as a core <br /> penetrometer or direct push technique instead of coring(EPA, 1993). <br /> Drum Storage <br /> Drums containing hazardous waste shall be stored in accordance with the <br /> requirements of 40 CFR 265 Subpart I(for containers)and 265 Subpart DD(for <br /> containment buildings). All 55-gallon drums will be stored at a secure, centralized on- , <br /> site location that is readily accessible for vehicular pick-up. Drums confirmed as,or <br /> believed to contain hazardous waste will be stored over an impervious surface <br /> provided with secondary containment.The storage location will,for drums containing <br /> liquid, have a containment system that can contain at least the larger of 10%of the <br /> aggregate volume of staged materials or 100%of the volume of the largest container. <br /> Drums will be closed during storage and be in good condition in accordance with the ' <br /> Guide to Management of Investigation-Derived Wastes(USEPA, 1992). <br /> g:leep.�mryeeamrtxtl mq 200Epenere!mpnt717E190.in,os.{pTonderled wnxe h�gsnp wE eorapeAx <br />
