5.14 WASTE MANAGEMENT <br /> Nonhazardous Wastewater <br /> The water balance diagram,provided in Figure 2.1-4,illustrates the expected liquid waste <br /> streams and flow rates for the LEC. The wastewater collection system will collect sanitary <br /> wastewater from sinks,toilets,and other sanitary facilities to be discharged to the WPCF. <br /> General facility drainage will consist of area washdown,sample drains,equipment leakage, <br /> and drainage from facility equipment areas.Water from these areas will be collected in a <br /> system of floor drains,hub drains, sumps,and piping, and will be routed to the facility's <br /> oil/water separator. If needed,water from this sump will be sampled and analyzed at an <br /> approved lab. If contamination is present,the water will be trucked off site for disposal at an <br /> approved wastewater disposal facility. If sampling results show no contamination,the <br /> water will be discharged to the onsite cooling towers,and the oily sludge will be shipped to <br /> an appropriate disposal facility. <br /> Hazardous Waste <br /> Hazardous waste generated will include waste lubricating oil,used oil filters from turbine <br /> equipment, spent catalyst, and chemical cleaning wastes. The catalyst units will contain <br /> heavy metals that are considered hazardous. Chemical cleaning wastes,consisting of <br /> alkaline and acidic cleaning solutions,will be generated from periodic cleaning of the <br /> piping. These wastes may contain high concentrations of heavy metals and will be collected <br /> for offsite disposal. <br /> The chemical feed area drains will collect spillage,tank overflows,effluent from <br /> maintenance operations, and liquid from area washdowns. Water collected will be sampled <br /> and,if it is not contaminated,will be released to the WPCF. The quantity of this effluent is <br /> expected to be minimal. <br /> Wastes that potentially will be generated during operations at the facility are summarized in <br /> Table 5.14-2. <br /> TABLE 5.14-2 <br /> Hazardous Wastes Generated During Operations <br /> Estimated <br /> Waste Origin Composition Quantity Classification Disposal <br /> Cooling Cooling tower Dirt from air 2,000 Ib/yr Hazardous/ TSDF facility if <br /> tower nonhazardous* hazardous. if <br /> sludge nonhazardous to <br /> landfill <br /> Lubricating Small leaks and Hydrocarbons 300 Ib/yr Hazardous Cleaned up using <br /> oil spills from the sorbent and rags— <br /> gas turbine disposed of by <br /> lubricating oil certified oil recycler <br /> system <br /> Batteries Equipment Metals 50 Ib/yr Hazardous Recycled by certified <br /> recycler <br /> Lubricating Gas turbine Paper, metal, 600 Ib/yr Hazardous Recycled by certified <br /> oil filters lubricating oil and oil recycler <br /> system hydrocarbons <br /> 5.14-6 SAC/371322/082330007(LEC_5.14_WASTE MANAGEMENT.DOC) <br />
