construction plan shall be included on all grading, utility, building, landscaping, and improvement plans during all phases of construction, access roads, parking areas and staging areas at construction sites. Site(s) affected: All Draft SEIR, pp. 4.B-14 to 4.B-16.) Impact 4.B-4 Development facilitated by the General Plan Amendment and rezonings could potentially include residential or mixed-use developments that could expose sensitive receptors to substantial health risk from diesel particulate matter ("DPM") and other toxic air contaminants TAC") from mobile and stationary sources. The SEIR evaluates the impact of the proposed project related to the exposure of sensitive receptors to diesel particulate matter (DPM) and other toxic air contaminants (TACs) from mobile and stationary sources. Roadway traffic, especially on Interstates 580 and 680, would be the primary sources of TACs near the potential sites for rezoning. In addition, BAAQMD indicates that there are 40 permitted TAC sources within 1,000 feet of one or more potential sites for rezoning. Significance Before Mitigation: Significant Significance After Mitigation: Less than Significant Finding: Changes or alterations have been required in or incorporated into the Project that would avoid or substantially lessen the significant environmental effect as identified in the SEIR. Mitigation Measure 4.B-4, which has been required in or 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 measures indicate that the impact will be reduced to less than significant. 1.Some of the potential sites for rezoning are within areas of concern from the TAC emissions from one or more of the stationary TAC sources. On-road vehicular traffic on nearby highway segments and arterials could also expose new residences on the potential sites for rezoning to TAC sources. 2.Implementation of Mitigation Measure 4.B-4 set forth in Table 6-1 of the Final SEIR and listed in the MMRP 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: 4.B-4: Reduce Exposure to TACs. On project sites where screening thresholds are exceeded, the following measures shall be implemented for development on all the potential sites for rezoning to reduce exposure to TACs and improve indoor and outdoor air quality:
