h. Power Failure <br /> The firewater pump will be driven by a diesel engine, and equipped with dc battery <br /> automatic starting provisions. An emergency diesel engine driven generator will be <br /> provided in the pumphouse to provide backup power to the stormwater sump pumps, <br /> scalehouse and the office area in the O&M Building. <br /> The computer system will be equipped with a battery backup uninterrupted power <br /> supply (UPS), with surge protection, for the computer electronics. <br /> D. Station Controls <br /> 1. Nuisance Control <br /> Potential nuisances are discussed on following sections. <br /> 2. Dust Control <br /> Station personnel will mechanically (sweeper vehicle) and manually sweep the <br /> Transfer Building floors daily to remove accumulated dust. The primary source of <br /> dust generation will be during unloading of waste and transfer into trailers. Design <br /> of ventilation fans will be included in the area of the transfer floor opening and the <br /> area where the raised floor of the unloading areas meets the tipping/sorting floor. <br /> Sprinklers (mist) to control dust will be included in the building. The system will be <br /> operable by timers or manually. It will be divided into multiple zones for separate <br /> usage. The sprinkler system will have piping separate from the fire suppression <br /> sprinklers. <br /> 3. Vector and Bird Control <br /> Vectors and birds are currently not a nuisance at the Station. Construction of a <br /> metal building over tipping and transfer areas should further reduce the potential that <br /> birds and vectors will be a problem at the Station. Waste will routinely be removed <br /> daily and at the most within 48 hours. Storage in the recycling areas will be of <br /> limited duration. In addition, Station management and operational personnel will <br /> survey both the recycling and transfer areas to check for harborage of vectors or <br /> birds. In the unlikely event that problems should occur, the County will take <br /> measures to eradicate vector or bird problems. <br /> 4. Drainage Control <br /> As described previously, no off-site drainage is proposed. The drainage system will <br /> consist of a network of catch basins and pipes draining into an unlined retention pond <br /> as shown on Drawing RSI-7. The retention basin will retain and collect site drainage <br /> for percolation and evaporation. The transfer tunnel and Recycling Storage area will <br /> each be provided with a sump and pump connected to the on-site drainage system. <br /> 07549001.012 41 September 23,1993 <br />
