City of Pleasanton—Vineyard Avenue Residential Project 15183 Consistency Checklist Consistency Checklist 43 modes of transportation, monitoring and improving existing sources of TACs throughout the City and reducing overall health impacts related to air quality in general. Furthermore, for project sites that would be located within siting distances recommended by the BAAQMD and ARB, currently published in the ARB Air Quality and Land Use Handbook: A Community Health Perspective, or the latest available guidance as determined by the City of Pleasanton as the lead agency, MM AIR-1b requires the preparation of a site-specific HRA and to mitigate potential risk to potential new sensitive receptors to less than significant levels. Adherence to the policies and programs of the General Plan would ensure compliance with existing BAAQMD policies to ensure the reduction of sensitive receptors exposure to toxic air contaminant. The Housing Element Update FEIR concluded that with the implementation of MM AIR-1b, sensitive receptors would not be exposed to substantial pollutant concentrations, and impacts would be less than significant. Proposed Project Analysis and Conclusion According to the AQ/GHG Assessment, the primary health risk impact issues associated with construction projects are cancer risks associated with diesel particulate matter (DPM), which is a known TAC, and exposure to high ambient concentrations of dust (i.e., PM2.5). Major sources of TACs include, but are not limited to, freeways, high traffic roads, distribution centers, and rail yards. Because DPM is identified as a TAC, high volume freeways, stationary diesel engines, and facilities attracting heavy and constant diesel vehicle traffic are identified as having the highest associated health risks from DPM. Health risks associated with TACs are a function of both the concentration of emissions and the duration of exposure, where the higher the concentration and/or the longer the period of time that a sensitive receptor is exposed to pollutant concentrations would correlate to a higher health risk. The proposed project does not include any operations that would be considered a substantial source of TACs, such as the aforementioned distribution centers or facilities attracting heavy and constant diesel vehicle traffic. Accordingly, operations of the proposed project would not expose the nearby sensitive receptors to excess concentrations of TACs. However, short-term, construction-related activities could result in the generation of TACs from on-road haul trucks and off-road equipment exhaust emissions. Although DPM emissions from on-road haul trucks would be widely dispersed throughout the project site and surrounding vicinity as haul trucks move goods and material to and from the site, exhaust from off-road equipment would primarily occur within the project site.
