Greystar ECR & Diller, Redwood City, CA - El Camino Real Cancer Risks First Floor On-Site Receptors - 1.5 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 2018 0.25 -0.25 - 0*10 0.0017 0.0000 0.0000 0.02 0.000 0.000 0.02 1 2018 1 1 10 0.0017 0.1114 0.3224 0.28 0.105 0.018 0.40 2 2019 1 2 10 0.0017 0.1114 0.3224 0.28 0.105 0.018 0.40 3 2020 1 3 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.06 4 2021 1 4 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.06 5 2022 1 5 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.06 6 2023 1 6 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.06 7 2024 1 7 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 8 2025 1 8 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 9 2026 1 9 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 10 2027 1 10 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 11 2028 1 11 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 12 2029 1 12 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 13 2030 1 13 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 14 2031 1 14 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 15 2032 1 15 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 16 2033 1 16 3 0.0017 0.1114 0.3224 0.04 0.016 0.003 0.064 17 2034 1 17 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 18 2035 1 18 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 19 2036 1 19 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 20 2037 1 20 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 21 2038 1 21 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 22 2039 1 22 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 23 2040 1 23 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 24 2041 1 24 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 25 2042 1 25 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 26 2043 1 26 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 27 2044 1 27 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 28 2045 1 28 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 29 2046 1 29 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 30 2047 1 30 1 0.0017 0.1114 0.3224 0.00 0.002 0.000 0.007 Total Increased Cancer Risk 1.3 0.5 0.1 1.8 * Third trimester of pregnancy 8.A. - Page 102
