4.1 – Air Quality Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.1-43 Threshold E: Would the Project result in cumulatively considerable air quality impacts? Less-Than-Significant Impact. A project’s emissions may be individually limited but cumulatively considerable when taken in combination with past, present, and future development within the SJVAB. If a project would result in a significant impact based on the SJVAPCD annual thresholds of significance for criteria pollutants, then the project would also be considered cumulatively significant. However, even if project emissions are below the annual significance thresholds for criteria pollutants, the impact may still be cumulatively significant. For instance, if a project results in criteria pollutant concentrations that exceed any of the federal health -based ambient air concentration standards or causes a worsening of areas already exceeding those standards, the project’s impacts would be considered individually significant and cumulatively significant. In addition, the combined emissions of a project and cumulative development located within the same area could potentially cause or worsen an exceedance of the concentration standards, whereby the project would have a cumulatively significant impact (SJVAPCD 2015a). In regard to TACs, because impacts are localized and the SJVAPCD thresholds of significance for TACs have been established at an extremely conservative level, risks that equal or exceed the individual thresholds of significance are also considered cumulatively significant (SJVAPCD 2015a). No other cumulative risk thresholds would apply. The SJVAPCD has not established cumulative significance thresholds regarding odor impacts. As set forth herein, Project construction would not generate emissions that would exceed the SJVAPCD annual thresholds; therefore, the Project’s cumulative impacts from construction would be less than significant. Because the Project would exceed the Project-level thresholds for regional NOx emissions during operation, the Project’s cumulative impacts with respect to such emissions would be considerable and significant. Project operation would not exceed the cancer risk, chronic hazard index, or acute hazard index thresholds with implementation of mitigation; therefore, the Project’s cumulative impacts with respect to impacts of TACs would be less than significant. Furthermore, the Project’s construction odor impacts would be short term and would disperse rapidly, and Project operation would not include land uses that generate odors. Therefore, Project construction and operations would result in a cumulative odor impact that is less than significant. 4.1.5 Mitigation Measures MM-AQ-1 Vehicle Miles Traveled Reduction Strategies. The Project shall implement a Transportation Demand Management (TDM) Program to facilitate increased opportunities for bicycling and pedestrian travel, as well as provide the resources, means, and incentives for ride-sharing and carpooling to reduce vehicle miles traveled and associated criteria air pollutant emissions. The following components shall be included in the TDM Program: Bicycle and Pedestrian Travel • Provide bicycle parking facilities of one bike rack space per 20 vehicle/employee parking spaces or to meet demand, whichever results in the greater number of bicycle racks. • Provide shower and locker facilities to encourage employees to bike and/or walk to work of one shower and three lockers per every 25 employees. Ride-Sharing and Commute Reduction • Promote ride-sharing programs through a multi-faceted approach, such as designating a certain percentage of parking spaces for ride-sharing vehicles, designating adequate
