5.9 PUBLIC HEALTH <br /> simultaneous operation of the existing NCPA Lodi power plant with the proposed LEC <br /> project. TAC emissions from the existing NCPA Lodi facility are shown in Table 5.1A-11, <br /> Appendix A (Air Quality). Details of the cumulative HRA are provided in Appendix 5.913. <br /> The results of the cumulative impact assessment of TACs are summarized in the Table 5.9-7. <br /> These results show that the maximum cumulative cancer, acute and chronic risks from the <br /> new plant and the existing plant are well below the levels that are considered significant. <br /> TABLE 5.9.7 <br /> Summary of Potential Cumulative Health Risks <br /> Carcinogenic Risk* Acute Health Hazard Chronic Health <br /> Receptor (per million) Index Hazard Index <br /> Maximum Incremental Cancer Risk, LEC 0.43 0.05 0.008 <br /> Maximum Incremental Cancer Risk, 4.1 0.009 0.003 <br /> Existing NCPA Lodi Power Plant <br /> Maximum Cumulative Combined 4.1 0.05 0.01 <br /> Cancer Risk <br /> Significance Level 10 1.0 1.0 <br /> *Derived (Adjusted) Method used to determine significance of modeled risks.

No additional mitigation <br /> measures are needed for the LEC TAC emissions because the potential air quality and <br /> public health impacts are less than significant. <br /> 5.9.7 Agencies and Agency Contacts <br /> Table 5.9-8 provides contact information for agencies involved with public health. <br /> TABLE 5.9-8 <br /> Agency Contacts for Public Health <br /> Issue Agency Contact <br /> Public exposure to air pollutants EPA Region 9 Gerardo Rios <br /> EPA Region 9 <br /> 75 Hawthorne Street <br /> San Francisco, CA 94105 <br /> (916)972-3974 <br /> Public exposure to air pollutants CARB Mike Tollstrup <br /> Project Assessment Branch <br /> California Air Resources Board <br /> 1001 1 Street <br /> Sacramento, CA 95812 <br /> (916)323-8473 <br /> SAC/371322/082340007(LEC_5.9_PUBLIC_HEALTH.DOC) 5.9-21 <br />
