Remediation System Well Abandonment Work Plan JACOBS° <br /> 55-gallon drums. Displaced groundwater and decontamination fluids will also be collected and contained <br /> in 55-gallon drums. <br /> Once containerized, the materials will be transported to a central area onsite for storage during <br /> characterization sampling. The drums will be placed on pallets, including secondary containment <br /> consisting of plastic beneath pallets that contain fluid-filled drums. Sand bags will be placed surrounding <br /> the plastic to create a berm and prevent fluids from reaching the ground. <br /> Waste characterization samples collected from the drill cuttings and decontamination fluids will be <br /> submitted to a California-certified laboratory, and results will be provided to PG&E for its use to establish <br /> waste profiles. Laboratory testing will include the following: <br /> • Gasoline, diesel, and motor oil range petroleum hydrocarbons measured as total petroleum <br /> hydrocarbons by U.S. Environmental Protection Agency (EPA) Method SW8015B <br /> • Semivolatile organic compounds by EPA Method 8270C <br /> • Volatile organic compounds by EPA Method SW8260 <br /> • Title 22 metals by EPA Method SW6010B/SW7471A <br /> • Ignitability, reactivity, and corrosivity by EPA Method SW-846 <br /> • pH by EPA Method SW9045C <br /> PG&E will be identified as the waste generator and a PG&E representative will sign the appropriate waste <br /> manifests. If necessary, a PG&E-authorized delegate will sign waste manifests on PG&E's behalf. The <br /> contractor will coordinate pickup of the waste containers at the Site. A contractor or PG&E representative <br /> will be on Site during waste removal activities. <br /> B11204191849AKT <br />
