nvironmental Checklist measures that, together with other approaches, may help reduce emissions in the City. These contribute to regional pollution control and greenhouse gas (GHG) reduction efforts. The BAAQMD notes a particular need to reduce exposure to particulates and TACs related to freeways and major arterials, especially those with high volumes of truck traffic, as well as exposure related to goods movement and distribution centers. Ambient concentrations of TACs are similar throughout the urbanized area of the Bay Area. The BAAQMD regulates TACs from stationary sources through their permit process; mobile sources of TACs are regulated indirectly through vehicle emissions standards and fuel specifications. The most recently adopted air quality plan for the Bay Area is the 2017 Clean Air Plan, which provides a regional strategy to protect public health and the climate. The Clean Air Plan control strategy includes 85 individual control measures to reduce emissions which are categorized into sectors, including stationary sources, transportation, energy, buildings, agriculture, natural and working lands, waste management, water, and super-GHG pollutants.13 Environmental Setting The primary factors that determine air quality are the locations of air pollutant sources and the amounts of pollutants emitted. Meteorological and topographical conditions, however, are equally important. Atmospheric conditions such as wind speed, wind direction, and air temperature gradients interact with the physical features of the landscape to determine the movement and dispersal of air pollutants. Two types of air pollutants affect air quality in the City: CAPs and TACs. The major source of air pollutants in the City is motor vehicle emissions. Heavy commute patterns throughout the Bay Area have resulted in poor regional air quality levels. The OAK airport terminal is located approximately 0.6 miles west and Interstate 880 is located approximately one mile east of the Proposed Project site. The region's attainment status for the NAAQS is listed in Table 3-2. The Bay Area is considered a nonattainment area for ground -level 03 and PM2.5 under both the CAA and CCAA. The area is also considered nonattainment for PM1O under the CCAA, but not the CAA. The area has attained both state and federal ambient air quality standards for CO. The BAAQMD adopted revised Air Quality Guidelines in April 2022, which contain CEQA thresholds of significance for projects, shown in Table 3-3. These thresholds are for 03 precursor pollutants (reactive organic gas [ROG] and nitrogen oxide [NOx]), PM1O, and PM2.5, and apply to both construction period and operational period impacts. If the daily average or annual emissions of operation -related CAPs or precursors exceeds any of these thresholds, the Proposed Project would result in a cumulatively significant impact.14 Additionally, the 2022 Air Quality Guidelines provide significance thresholds for odors at five confirmed complaints per year averaged over a period of 3 years in the project source area.15 13 Bay Area Air Quality Management District (BAAQMD). 2017.
