LFR Levine-Fricke area will be reviewed and any water control measures will be implemented as needed in accordance with the site specific Storm Water Pollution Prevention Plan. Decontamination pads for loaded trucks will be located along each exit route within the Site. A minimum of two decontamination areas will be established to clean construction equipment and vehicles. Vehicles shall be decontaminated before departing the Site to prevent the tracking of contaminated soil off site. Trucks will be decontaminated using a waterless decontamination method. If water is necessary to decontaminate a vehicle, a water containment barrier will be constructed and water used for decontamination will be contained, sampled, and disposed of properly under the supervision of a CIWMB project manager/engineer. The trucks will proceed to the appropriate staging area for loading. The weight of each truck and trailer will be assumed based on the known dry weights. Trucks will then proceed to the scaling area where they will be weighed and trimmed to no more than 80,000 pounds. This process will ensure that trucks are loaded within their load limit and that the hauling process is maximized. Trucks will then proceed to the decontamination and tarping area(Figure 5)where they will be cleaned with brushes. Truck decontamination shall proceed in two separate stages. The first stage will consist of four to six laborers working in shifts to minimize stress and exposure to waste materials. The trucks shall proceed through two elevated scaffolding platforms where one laborer will direct and stop the truck. Then two more laborers will mount the platforms and brush the outer walls and the top of the trailers. While at the decontamination area, each truck shall have its load covered with tarps to prevent loss of waste during transport. Following decontamination and covering, trucks will proceed through the second stage of decontamination, a gravel pad, approximately 20 feet wide and 100 feet long, laid with 1.5-to 2-inch crushed rock. The rock will remove waste material that may remain in the treads of the tires before the trucks leave the site. Trucks will then proceed to the manifest area. At no point during the loading or decontamination process should the truck driver exit their truck. This will minimize the driver's potential exposure to waste materials. Excavation equipment will be decontaminated by a dry method. Equipment will not be allowed out of the work area without being decontaminated. Equipment decontamination stations shall be set up at work areas within each unit. Decontamination shall be performed by individuals in personal protective equipment (PPE), using brushes as deemed appropriate in the HSP throughout the process. Personnel will also be decontaminated by a dry method. Personnel shall not leave the work area without first proceeding through a tarp-lined personal decontamination station, which will be established at each work area near each unit. Personnel shall complete decontamination by removing and properly disposing of PPE. They will be required to dry brush their boots as well. Site personnel will then proceed to a designated wash area where they will wash their hands/faces before leaving the work area. Personal respiratory equipment will be cleaned daily and all cleaning materials Final_RAP_Tracy_9.18.03(final).doc Page 21
