5.5 HAZARDOUS MATERIALS HANDLING <br /> Regulated substances,as defined in California Health and Safety Code,Section 25531,will <br /> not be used during construction of the project. Therefore,no discussion of regulated <br /> substances storage or handling is included in this section. <br /> 5.5.1.2.2 Operations Phase <br /> Storage locations for the hazardous materials that will be used during operation are <br /> described in Table 5.5-1.Table 5.5-2 presents information about these materials,including <br /> trade names,chemical names, Chemical Abstract Service (CAS) numbers,maximum <br /> quantities onsite,reportable quantities (RQ), California Accidental Release Program <br /> (CalARP) threshold planning quantities (TPQs),and status as a Proposition 65 chemical <br /> (a chemical known to be carcinogenic or cause reproductive problems in humans). Health <br /> hazards and flammability data are summarized for these materials in Table 5.5-3,which also <br /> contains information on incompatible chemicals (e.g., sodium hypochlorite and ammonia). <br /> Most of the hazardous substances that will be used by the project are required for facility <br /> maintenance and lubrication of equipment, or will be contained within transformers and <br /> electrical switches. Two regulated substances will be used for the project,anhydrous <br /> ammonia and hydrogen;toxicity characteristics and the exposure level criteria for these <br /> regulated substances are included in Table 5.5-4. <br /> 5.5.2 Environmental Analysis <br /> Construction and operation of the project will involve the use of various hazardous <br /> materials and two regulated substances. The use of these materials and their potential to <br /> cause adverse environmental and human health effects are discussed in this section. <br /> 5.5.2.1 Significance Criteria <br /> The project could have a significant effect on the environment in terms of hazardous materials <br /> handling if it would do the following (CEQA Guidelines Section 15002[g],Appendix G): <br /> • Create a significant hazard to the public or the environment through the routine <br /> transport or use of hazardous materials. <br /> • Create a significant hazard to the public or the environment through reasonably <br /> foreseeable upset and accident conditions involving the release of hazardous materials <br /> into the environment. <br /> • Emit hazardous emissions or handle hazardous materials, substances, or waste within <br /> one-quarter mile of an existing or proposed school. <br /> 5.5.2.2 Transportation of Hazardous Materials <br /> Project operation will require regular transportation of hazardous materials to the project <br /> site (see also Section 5.12,Traffic and Transportation). Transportation of hazardous <br /> materials will comply with all California Department of Transportation (Caltrans), <br /> U.S. Environmental Protection Agency (EPA), California Department of Toxic Substances <br /> Control (DTSC), California Highway Patrol (CHP),and California State Fire Marshal <br /> regulations. Anhydrous ammonia, a regulated substance,will be delivered to the facility <br /> and transported in accordance with Vehicle Code Section 32100.5,which regulates the <br /> transportation of hazardous materials that pose an inhalation hazard. <br /> 5.5-2 SAC/371322/082330015(LEC_5.5_HAZMAT.DOC) <br />
