The BAAQMD prepared a GIS tool that contains pre-estimated <br />cancer risk and PM2.5 concentration increases for highways within the Bay Area. Highway 680 is <br />approximately 940 feet west and of the MIR, and Highway 580 is approximately 3,300 feet north <br />of the MIR. <br />• Stationary Source Risk and Hazard Screening Tools. The BAAQMD prepared a GIS tool 26 with <br />the location of permitted stationary sources. For each emissions source, the BAAQMD <br />provides conservative estimates of cancer risk and PM2.5 concentrations. Based on the GIS <br />tool's information, no BAAQMD-permitted stationary source is within 1,000 feet of the MIR. <br />• Rail Screening Tools. The BAAQMD prepared GIS tools that contains estimated cancer risks <br />and PM2.5 concentrations from railroad operations at any point within the Air Basin. The <br />closest rail line to the MIR is the BART line running along Highway 580, approximately 3,350 <br />feet north of the MIR. <br /> <br />The cumulative health risk results, including health risks from the existing stationary source, are <br />summarized during project construction in Table 10. Cumulative health risk results shown therein <br />are representative of the health risks to the MIR, which would experience the highest concentration <br />of pollutants. <br />Table 10: Summary of the Cumulative Health Impacts at the MIR during Construction <br />Source Source Type <br />Distance <br />from MIR(1) <br />(feet) <br />Cancer Risk <br />(per <br />million) <br />Chronic <br />HI <br />PM2.5 <br />Concentration <br />(µg/m3) <br />Project <br />Mitigated Project Construction Diesel Construction <br />Equipment 130 1.49 <0.01 0.01 <br />Roadways <br />Existing Local Roadways 100 0.25 N/A <0.01 <br />Rail <br />Existing Rail Lines 3,350 0.43 N/A <0.01 <br />Freeway <br />Existing Freeways 3,300 19.16 N/A 0.32 <br />Cumulative Health Risks <br />Cumulative Total with Project Construction 21.33 <0.01 0.42 <br />BAAQMD’s Cumulative Thresholds of Significance 100 10 0.8 <br />Threshold Exceedance?
