SECTION 2.0:PROJECT DESCRIPTION <br /> Chemical cleaning wastes will consist of alkaline and acid cleaning solutions used during <br /> pre-operational chemical cleaning and turbine washwaters. These wastes,which are subject <br /> to high metal concentrations,will be temporarily stored on site in portable tanks or sumps, <br /> and disposed of off site by the chemical cleaning contractor in accordance with applicable <br /> regulatory requirements. <br /> 2.1.13 Management of Hazardous Materials <br /> There will be a variety of chemicals stored and used during construction and operation of <br /> LEC. The storage,handling, and use of all chemicals will be conducted in accordance with <br /> applicable laws,ordinances,regulations,and standards (LOBS). Chemicals will be stored in <br /> appropriate chemical storage facilities. Bulk chemicals will be stored in storage tanks, and <br /> most other chemicals will be stored in returnable delivery containers. Chemical storage and <br /> chemical feed areas will be designed to contain leaks and spills. Secondary concrete <br /> containment pits and drain piping design will contain a full-tank capacity spill and will <br /> prevent chemicals from overflowing the containment area. Each containment area will <br /> include a manually operated valve that will allow stormwater to be drained to the plant <br /> wastewater system after the water has been tested to ensure no hazardous substances are <br /> present. For multiple tanks in the same containment area,the capacity of the largest single <br /> tank will determine the volume of the containment area and drain piping. Drain piping for <br /> reactive chemicals will be trapped and isolated from other drains to eliminate noxious or <br /> toxic vapors. <br /> The existing anhydrous ammonia storage and delivery area currently has both spill <br /> containment and ammonia vapor detection equipment. <br /> Safety showers and eyewashes will be provided adjacent to,or in the vicinity of,chemical <br /> storage and use areas. Plant personnel will use approved personal protective equipment <br /> during chemical spill containment and cleanup activities. Personnel will be properly trained <br /> in the handling of these chemicals and instructed in the procedures to follow in case of a <br /> chemical spill or accidental release. Adequate supplies of absorbent material will be stored <br /> on site for spill cleanup. <br /> A list of the chemicals anticipated to be used at LEC and their storage locations is provided <br /> in Section 5.5,Hazardous Materials Handling. This list identifies each chemical by type, <br /> intended use, and estimated quantity to be stored onsite. <br /> 2.1.14 Fire Protection <br /> The fire protection system will be designed to protect personnel and limit property loss and <br /> plant downtime in the event of a fire. Fire water will be supplied by the WPCF and stored in <br /> the raw water/fire water storage tank at the existing STIG plant. The project will tie into the <br /> existing fire system currently in use at the STIG plant. The connection will be sized in <br /> accordance with National Fire Protection Association (NFPA) guidelines to provide 2 hours <br /> of protection for the onsite worst-case single fire. <br /> Fire water from WPCF will be provided to a dedicated underground fire loop piping system <br /> or an onsite storage tank. Both the fire hydrants and the fixed suppression systems will be <br /> supplied from the fire water loop. Fixed fire suppression systems will be installed at <br /> determined fire risk areas.Sprinkler systems will also be installed in the water treatment <br /> SACI371322I082340003(LEC_2.0_PROJECT_DESC.DOC) 2-29 <br />
