Personnel take <br /> immediate action to have these items removed. <br /> 6.41 Water <br /> Water increases bacteria growth, which causes sludge and algae to develop. Technicians check the <br /> monitoring unit printout and LED display for water in the UST and have any water removed as soon as <br /> possible. <br /> 6.4.2 Other Contaminants <br /> Dirt, sand and other contaminants routinely find their way into the fuel stored in USTs. Fuel should be <br /> sampled at two-year intervals to check for contaminants. <br /> When sampling for contaminants,it is important to sample the fuel during or just after the generator has <br /> been run. The action of drawing fuel from the tank causes settled contaminants to become suspended <br /> in the fuel and pumped to the generator. <br /> The sample is sent to a certified lab and tested for contaminants. When fuel contamination levels <br /> exceed 20 parts per million, the fuel must be removed from the tank and disposed of. (Refer to section <br /> 6.2 for proper disposal procedures.) While the UST is empty, the tank itself must be cleaned. Failure <br /> to clean the tank will cause any new fuel stared in the tank to be contaminated also. The generator <br /> maintenance vendor is responsible,by contract, for pulling fuel samples and testing them during regular <br /> scheduled maintenance visits. BMC is responsible for maintaining documentation of testing and all <br /> action items performed. <br /> Fuel tank cleaning is contracted with a professional decontamination company. <br /> 10 <br /> Copyright 01999-2001 Sprint Corporation <br /> The information in this document is proprietary.
