Air Quality Madeling Report 5. Modeling and Health Risk Analysis Results Asummary of the PM, ; NAAQS analysis is presented belaw in Table 5-1. The modeled concentrations presented represent the twelve (12) wood-fired smokers operating 12 hours per day for 365 days each year and the five years of meteorological data used in AERMOD. The maximum modeled concentrations were then addad to representative ambient background concentrations to estimate the total concentrations compared to the NAAQS. As shown, the total concentrations for 24-hour and annual PM25 are less than the NAAQS. Figure 5-1 and Figure 5-2 depict the 24-hour and annual PM2s5modeled concentration isopleths, respectively, showing the location of maximum concentrations and distribution of the modeled concentratians. The result of this analysis indicates that the Project will not cause or contribute to a violation of the PM2s NAAQS. Table 5-1 Summary of PMz.s NAAQS Analysis Ambient .
