Work Plan <br /> Facility Demolition and Soil Excavation <br /> J Stockton,California <br /> Sierra-Pacific Project No.95-128.06 <br /> J <br /> Contract workers will use protective clothing, steel-toed boots, gloves, full-faced respirators, and <br /> other essential items to avoid being injured by exposure to sulfuric acid, phosphoric acid, and other <br /> corrosive chemicals which may be present in buried pipes. Each buried structure must be demolished <br /> or removed with extreme caution. As discussed in section 3.1 all buried product lines will be <br /> vacuumed-out prior to demolition. <br /> ASTs which contained ammonia-based products or flammables, will be tested for combustible gases <br /> and vapors prior to cutting or welding. The percent oxygen and Lower Explosive Limits (LEL) will <br /> be determined prior to cutting and welding on these ASTs. Tanks will be filled with dry-ice prior to <br /> cutting, if necessary. <br /> During the demolition work, the contractor will attempt to minimize the volume of spilled feed <br /> products and other liquids by using plastic sheeting or containers. Spill control equipment will be <br /> placed underneath pipe connections, man ways, and valves prior to their removal. Any remaining <br /> residual feed products or decontamination rinsates will be placed in an open poly-tank provided by <br />-r Cargill. Relatively pure feed product constituents will be placed in 55-gallon drums or ASTs. Acids <br /> and bases will be stored separately in safe and product compatible containers. Labels, identifying the <br /> contents of each drum or container will be placed on all containers. Cargill's plant supervisor will <br /> be informed immediately should workers discover an unknown substance or significant volume of <br /> product. <br /> Scrap metal will be staged at the site in steel roll-off containers, or directly transported from the site <br /> to the salvage yard or landfill. During the demolition work, steel scrap metal will be staged, in a <br /> predetermined location, at the site for recycling. Items designated for recycling will be <br /> decontaminated, if necessary, using a high-pressure washer prior to stockpiling the material.
