5.14 WASTE MANAGEMENT <br /> will be recycled where practical and nonrecyclable waste will be deposited in a Class III <br /> landfill. <br /> Wastewater <br /> Wastewater generated during construction will include sanitary waste,stormwater runoff, <br /> equipment washdown water,and water from excavation dewatering during construction <br /> (if dewatering is required). Depending on the chemical quality of these wastewaters,they <br /> could be classified as hazardous or nonhazardous. As discussed in a later section, <br /> wastewater would be sampled and if found hazardous would be disposed of. Methods for <br /> disposing of nonhazardous wastewaters are identified in Section 5.14.1.2.2. <br /> Hazardous Waste <br /> Most of the hazardous waste generated during construction will consist of liquid waste, <br /> such as water from excavation dewatering(if it contains contaminants),flushing and <br /> cleaning fluids,passivating fluid (to prepare pipes for use), and solvents. Some hazardous <br /> solid waste, such as welding materials and dried paint,may also be generated during <br /> construction. <br /> Flushing and cleaning waste liquid will be generated as pipes are cleaned and flushed. The <br /> volume of flushing and cleaning liquid waste generated is estimated to be one to two times <br /> the internal volume of the pipes cleaned. The quantity of welding,solvent, and paint waste <br /> is expected to be minimal. Wastewater generated during construction could also be <br /> considered hazardous,if demonstrated so by sampling. Methods for recycling and disposal <br /> of hazardous wastes during construction are described in a Section 5.14.2.3. <br /> The construction contractor will be considered the generator of hazardous construction <br /> waste and will be responsible for proper handling of hazardous waste in compliance with <br /> all applicable federal, state, and local laws and regulations. This responsibility will include <br /> licensing,personnel training, accumulation limits and times,and reporting and <br /> recordkeeping. The hazardous waste will be collected in satellite accumulation containers <br /> near the points of generation. It will be moved daily to the contractor's 90-day hazardous <br /> waste storage area located at the site construction laydown area. The waste will be removed <br /> from the site by a certified hazardous waste collection company and delivered to an <br /> authorized hazardous waste management facility,before expiration of the 90-day storage <br /> limit. <br /> 5.14.1.2.2 Operation Phase <br /> During LEC facility operation,the primary waste generated will be nonhazardous solid <br /> waste. However,varying quantities of both solid and liquid hazardous waste will also be <br /> generated periodically. The types of wastes and their estimated quantities are discussed <br /> below. <br /> Nonhazardous Solid Waste <br /> The LEC will produce facility wastes, typical of power generation facility operations and <br /> maintenance activities. These will include rags,turbine air filters,broken and rusted metal <br /> and machine parts, defective or broken electrical materials,empty containers,the typical <br /> refuse generated by workers and small office operations, and other miscellaneous solid <br /> wastes. The quantity of all solid nonhazardous waste generated is estimated to be <br /> approximately 39 tons per year. Large metal parts will be recycled. <br /> SACI3713221082330007(LEC_5.14_WASTE MANAGEMENT.DOC) 5.14-5 <br />
