Typically the minimum level of significance <br />provided by the BAAQMD for stationary sources is a cancer risk of 10 in <br />a million. However, risks from mobile sources are often acceptable at <br />higher levels, and therefore the significance thresholds would be <br />established by the HRA in consultation with the City. The HRA shall take <br />into consideration the ultimate widening of I-580, and will assume that the <br />closest travel lane by the Staples Ranch site will shift south by 32 feet, if <br />Caltrans has not adopted its plans by the time the health risk assessment is <br />conducted. If residents are proposed for areas where exposure could <br />exceed the established threshold, then the HRA shall make <br />recommendations for reducing exposure to on-site residents. <br />Recommendations could include increasing the distance between residents <br />and the freeway, modification to the location and height of intakes to the <br />ventilation system, addition of HEPA air filtration systems, or reducing <br />outdoor use areas, such as patio areas and balconies. <br />Biological Resources <br />BIO -2.1 Conduct preconstruction surveys for CRLF.
