4.1 – Air Quality Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.1-25 If a project would result in an odor source with sensitive receptors located within these screening distances, additional analysis would be required. For projects involving new receptors locating near an existing odor source where there is currently no nearby development, and for new odor sources locating near existing receptors, the SJVAPCD recommends the analysis be based on a review of odor complaints for similar facilities, with consideration also given to local meteorological conditions, particularly the intensity and direction of prevailing winds. Regarding the complaint record of the odor source facility (or similar facility), the facility would be considered to result in significant odors if there has been (SJVAPCD 2015a): • More than one confirmed complaint per year averaged over a 3-year period. • Three unconfirmed complaints6 per year averaged over a 3-year period. Cumulative 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, if a project’s 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. Approach and Methodology Project Design Features The following project design features (PDFs) would be included as part of the Project: PDF-AQ-1 Prior to the County of San Joaquin’s (County) approval of any grading permits and during Project construction, a Fugitive Dust Control Plan shall be prepared demonstrating compliance with San Joaquin Valley Air Pollution Control District’s (SJVAPCD) Rules 8021, 8031, 8041, 8051, 8061, and 8071, to the satisfaction of the County. The Project applicant or its designee shall require implementation of the following fugitive dust measures to minimize course particulate matter emissions as part of the Fugitive Dust Control Plan. All measures shall be designated on Grading Plans. a. Grading areas shall be watered, or another SJVAPCD-approved dust control non-toxic agent shall be used, at least three times daily to minimize fugitive dust only where chemical stabilizers are not used. b. All permanent roads and the paved access roadway improvements shall be constructed and paved as early as possible in the construction process to reduce construction vehicle travel on 6 An unconfirmed complaint means that either the odor/air contaminant release could not be detected or the source/facility cannot be determined (SJVAPCD 2015a).
