handling, and waste within trucks leaving the Site will be covered prior to departure. Trucks will also be inspected for excess soil, dust, and debris prior to departure. If excess soil, dust, or debris is found during inspection, the trucks will be decontaminated prior to departure. Transportation of any hazardous waste will comply with Department of Transportation requirements for safe handling and transportation of hazardous materials. Excavation activities will be performed in accordance with an approved Health and Safety Plan (HSP) prepared in accordance with California Code of Regulations, Title 7, Section 5192 for protection of workers, and in accordance with DTSC policies and procedures for the protection of the environment and community. The HSP will contain specific measures to control airborne contamination (i.e., dust control will be implemented)and prevent site worker exposure to potentially hazardous conditions through a combination of administrative controls, engineering controls, and personal protective equipment. The HSP will also include provisions for specific health and safety monitoring that will occur during remediation, to protect remediation workers from chemicals at levels above site-specific goals and that site-related contaminants are not being transported off site during remediation. Material excavated for disposal will either be loaded directly into trucks or placed temporarily in a bermed stockpile. Stockpiled material will be placed on plastic sheeting and will be covered with additional plastic sheeting. During loading and stockpiling,water will be sprayed onto the waste prior to and during loading and excavating activities to reduce particulate emissions. A polyethylene liner will be placed in trucks or containers used for transportation of waste material. The waste will be misted with water and plastic sheeting or a tarpaulin will be placed over the material and secured before transportation. To efficiently accommodate staging and truck decontamination, there will be three general work areas based on topography. Each work area will contain burn piles located in the same general region of the Site. Thus, work on the Site will be divided among three main areas. The staging areas will be placed in established roads on the Site, leading towards the main gate that will serve as the entrance and exit. Decontamination Pads will be located along each exit route. The Site consists of 34 distinct burn-pile areas (Figure 2). The burn-pile areas have been grouped into three separate units for phased excavation. Unit 1 is the most northerly of the three units and consists of burn-pile areas 1, 2, 3, 4, 5, and 9. Unit 2 is located adjacent to Unit 1 on the south and consists of burn-pile areas 6, 7, 8, 10, 11, and 12. Unit 3 is located adjacent to Unit 2 on the south and east, and consists of burn-pile areas 13-34. The site contractor will use a waterless ("dry")decontamination method.The trucks will proceed to the staging area where they will be loaded and will then proceed to the scaling area where they will be weighed and trimmed. After loading, weighing, and trimming, the trucks will proceed through two elevated scaffolding platforms to the first of two decontamination pads. Two laborers will mount the platforms and then brush the outer walls and the top of the trailers. They will then tarp and secure the load. The truck will drive forward through the 20x100-foot lined gravel area, to remove residual material from the tire treads, to the manifest area where all manifests will be completed and signed.To minimize potential exposure, truck drivers will not be allowed to exit the truck during loading or truck decontamination. Personnel will also be"dry'decontaminated. Employees will not be allowed to leave the Site without first removing their personal protective equipment(PPE) and properly disposing of the waste in the proper container. Each "decontamination area"will consist of a tarp lined pad where the employees will remove PPE and dispose of them in a designated container. After decontamination has been completed, employees will then proceed to the supplied hand wash stations. Respiratory equipment will be cleaned daily and cleaning materials and filters will then be disposed into the proper container. The PPE waste will be loaded into the waste hauling trucks and transported to the proper disposal facility. 30
