to the determination of whether a project's individual emissions would have a cumulatively significant impact on air quality. Pursuant to the SJVAPCD's guidance, if project-specific emissions would be less than the thresholds of significance for criteria pollutants, the project would not be expected to result in a cumulatively considerable net increase of any criteria pollutant for which the SJVAPCD is in nonattainment under applicable federal or State ambient air quality standards. As project emissions would not exceed SJVAPCD significance thresholds, the cumulative impacts of these emissions would be less than significant. c) Exposure of Sensitive Receptors. As defined in the Guide for Assessing and Mitigating Air Quality Impacts, "sensitive receptors" include residences, schools, parks and playgrounds, day care centers, nursing homes, and hospitals (SJVAPCD 2015). The existing residences in the vicinity, along with the proposed single-family residences that would be allowed to develop as a result of the project, would be considered sensitive receptors. Exposure of existing residences to project construction emissions would be short-term and therefore would not have a lasting impact on health or well-being. As indicated in Table 3-2 above, project operational emissions would not exceed SJVAPCD significance thresholds. As discussed in a) above, the significance thresholds were established in part to ensure consistency with the objectives of air quality attainment plans adopted by the SJVAPCD. These plans are intended to have the Air Basin attain both federal and State ambient air quality standards, including federal primary standards designed to protect human health. Sensitive receptors in the vicinity of the project site would not be exposed to any substantial air pollutant emissions from project construction or operations. The project would have no impact on sensitive receptors. d) Odors and Other Emissions. The project proposes the development of residential subdivisions, with no development of significant sources of odors such as industrial plants and wastewater treatment plants. The main emissions of concern that could affect sensitive receptors are TACs, specifically diesel particulate matter emissions, prolonged exposure to which could lead to serious health effects, including cancer. The main source of diesel particulate matter emissions is diesel engines, which with the project would be limited mainly to construction equipment. Such equipment would be used only until project construction work is completed. Project construction would not result in prolonged exposure of sensitive receptors to diesel particulate matter emissions. Diesel particulate matter emissions from project operations typically are generated by trucks, buses, and other large vehicles; relatively few passenger vehicles have diesel engines. It is expected that the project, being residential, would generate few trips by large vehicles with diesel engines. The exhaust PMIo emissions calculated by CalEEMod provide a reasonable representation of diesel particulate matter emissions. According to the CalEEMod results, the project would generate approximately 0.05 tons of exhaust PMIo annually, or approximately 0.27 pounds per day. This amount is small and expected Pock Lane Public Review Draft IS/MND 3-11 May 2022
