The Draft SEIR evaluates the impacts related to the exposure of sensitive receptors, such as senior housing or outdoor recreation within the Project, in close proximity to sources of toxic air contaminants (i.e., within 300 feet of a fuel station or within 1,000 feet of warehouse loading docks or Highway 1-680). Significance Before Mitigation: Significant Significance After Mitigation: Less than Significant Finding: Changes have been incorporated into the Project that would avoid the significant environmental effect as identified in the Revised Final SEIR. Mitigation Measure 4.B-4,which has been incorporated into the Project, will reduce the significant environmental impact to a less than significant level. Facts in Support of Finding: The following facts and mitigation measure indicate that the impact will be reduced to less than significant. 1. Some of the sites within the Project that would be developed are within areas of concern related to TAC emissions from one or more stationary TAC sources. On-road vehicular traffic on nearby highway segments and arterials could also expose receptors within the area of the Project to TAC sources. 2. Implementation of Mitigation Measure 4.B-4 set forth in Table 5-1 of the Final SEIR and listed in the RMMRP will ensure that Impact 4.B-4 would be reduced to a less than significant level, and is hereby incorporated by reference and described below. Mitigation Measure 4.B-4: If a new sensitive residential use, such as senior housing or a child-care or healthcare facility, is proposed within the EDZ area and within 300 feet of a fuel station or within 1,000 feet of warehouse loading docks or Highway 1-680, the developer of this use shall prepare a health risk assessment report to be reviewed and approved by the City. The health risk assessment shall demonstrate that the increased cancer risks for the proposed sensitive use would be below the BAAQMD permitting limit of 10 in one million(per its Policy and Procedure Manual,the BAAQMD would deny an Authority to Construct or a Permit to Operate for any new or modified source of TACs that exceeds a cancer risk of 10 in one million or a chronic or acute hazard index of 1.0); or, should the health risk assessment determine that lifetime cancer risk would exceed 10 in one million,the developer shall install in the sensitive use an enhanced ventilation filtration system such that the resultant lifetime increased cancer risk is less than 10 in one million. No sensitive use shall be approved within the EDZ where the health risk assessment determines that lifetime cancer risk from the freeway and from uses in the EDZ would exceed 10 in one million.
