Calculate risk of cancer in cases per million (R) <br /> R = (L/70) (X) (UR) (0 . 1 ) <br /> where, <br /> R = risk of cancer <br /> L = lifetime of project <br /> = 2 years (As per applicant) <br /> X = maximum hourly concentration <br /> = 743 . 65 µg/m3 <br /> UR = unit risk factor for gasoline <br /> = 1 . 2E-06 <br /> therefore, <br /> R = (2/70) (743 . 65) ( 1 . 2E-06) (0 . 1 ) <br /> = 2 . 55E-06 or 2 . 55 cases/ millon <br /> The health risk factor is , therefore, estimated to be less than the maximum allowable risk <br /> factor of 10 in a million . As long as the control equipment is properly maintained and <br /> operated the proposed equipment will meet the health risk policy of less than 10 cases <br /> in a million . <br /> Emissions will not impose any nuisance or discomfort to any individuals if the equipment <br /> is operated and maintained properly . <br /> 10 <br />
