Greystar ECR & Diller, Redwood City, CA - El Camino Real Cancer Risks Second Floor On-Site Receptors - 6.0 meter Receptor Heights Cancer Risk Calculation Method Cancer Risk (per million) = CPF x Inhalation Dose x ASF x ED/AT x FAH x 1.0E6 Where: CPF = Cancer potency factor (mg/kg-day)-1 ASF = Age sensitivity factor for specified age group ED = Exposure duration (years) AT = Averaging time for lifetime cancer risk (years) FAH = Fraction of time spent at home (unitless) Inhalation Dose = Cair x DBR x A x (EF/365) x 10-6 Where: Cair = concentration in air (μg/m3) DBR = daily breathing rate (L/kg body weight-day) A = Inhalation absorption factor EF = Exposure frequency (days/year) 10-6 = Conversion factor Values Cancer Potency Factors (mg/kg-day)-1 TAC CPF DPM 1.10E+00 Vehicle TOG Exhaust 6.28E-03 Vehicle TOG Evaporative 3.70E-04 Infant/Child Adult Age -->3rd Trimester 0 - <2 2 - <16 16 - 30 Parameter ASF 10 10 3 1 DBR* = 361 1090 572 261 A = 1 1 1 1 EF = 350 350 350 350 ED = 0.25 2 14 14 AT = 70 70 70 70 FAH = 1.00 1.00 1.00 0.73 * 95th percentile breathing rates for infants and 80th percentile for children and adults Road Traffic Cancer Risk by Year - Maximum Impact Receptor Location Maximum - Exposure Information Exposure Age Annual Conc (ug/m3)Cancer Risk (per million) Exposure Duration Sensitivity TOG TOG TOG TOG Year Year (years)Age Factor DPM Exhaust Evaporative DPM Exhaust Evaporative Total 0 2019 0.25 -0.25 - 0*10 0.0027 0.0000 0.0000 0.04 0.000 0.000 0.04 1 2019 1 1 10 0.0027 0.1748 0.5056 0.44 0.164 0.028 0.63 2 2020 1 2 10 0.0027 0.1748 0.5056 0.44 0.164 0.028 0.63 3 2021 1 3 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.10 4 2022 1 4 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.10 5 2023 1 5 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.10 6 2024 1 6 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.10 7 2025 1 7 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 8 2026 1 8 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 9 2027 1 9 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 10 2028 1 10 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 11 2029 1 11 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 12 2030 1 12 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 13 2031 1 13 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 14 2032 1 14 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 15 2033 1 15 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 16 2034 1 16 3 0.0027 0.1748 0.5056 0.07 0.026 0.004 0.099 17 2035 1 17 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 18 2036 1 18 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 19 2037 1 19 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 20 2038 1 20 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 21 2039 1 21 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 22 2040 1 22 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 23 2041 1 23 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 24 2042 1 24 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 25 2043 1 25 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 26 2044 1 26 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 27 2045 1 27 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 28 2046 1 28 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 29 2047 1 29 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 30 2048 1 30 1 0.0027 0.1748 0.5056 0.01 0.003 0.000 0.011 Total Increased Cancer Risk 2.0 0.7 0.1 2.8 * Third trimester of pregnancy 8.A. - Page 104
