Environmental Impacts of the Proposed Changes to the Original Project
<br />
<br />Addendum to the City of Pleasanton Downtown Specific Plan Final Environmental Impact Report 23
<br />The project would incorporate advanced engine tiers into construction equipment, such as loaders,
<br />excavators, and rollers, which would be equipped with either Tier 3 or Tier 4 engines. Some
<br />construction equipment would be equipped with diesel particulate filter technology. In addition,
<br />pursuant to Mitigation Measure AQ-1 of the Final EIR, this analysis conducted project-specific
<br />analysis using CalEEMod and found construction emissions were well below BAAQMD’s regional
<br />thresholds. Therefore, construction health impacts would be less than significant.
<br />CARB’s Air Quality and Land Use Handbook: A Community Health Perspective (2005) provides
<br />recommendations regarding the siting of new sensitive land uses near potential sources of air toxic
<br />emissions (e.g., freeways, distribution centers, rail yards, ports, refineries, chrome plating facilities,
<br />dry cleaners, and gasoline dispensing facilities). CARB guidelines recommend siting distances both
<br />for the development of sensitive land uses in proximity to TAC sources and for the addition of new
<br />TAC sources in proximity to existing sensitive land uses. The Barone’s project is not near potential
<br />sources of TAC emissions as listed above. In addition, single-family units and general commercial
<br />land uses are not considered land uses that generate substantial TAC emissions based on reviewing
<br />the air toxic sources listed in CARB’s guidelines. Therefore, the expected hazardous TACs generated
<br />on site (e.g., cleaning solvents, paints, landscape pesticides, etc.) for the proposed land uses would
<br />be below thresholds warranting further study under the California Accidental Release Program. The
<br />Barone’s project would not expose off-site sensitive receptors to significant amounts of carcinogenic
<br />or TACs. Therefore, operational impacts would be less than significant.
<br />ODORS
<br />The project would generate oil and diesel fuel odors during construction from equipment use. The
<br />odors would be limited to the construction period and would be intermittent and temporary.
<br />Furthermore, these odors would dissipate rapidly with distance from in-use construction
<br />equipment. Accordingly, project construction would not result in other emissions, such as those
<br />leading to odors, that would adversely affect a substantial number of people, and impacts would be
<br />less than significant.
<br />According to the BAAQMD’s 2022 CEQA Guidelines (2023), land uses associated with odor
<br />complaints to include, but not limited to, wastewater treatment plants, landfills, confined animal
<br />facilities, composting stations, food manufacturing plants, refineries, and chemical plants. The
<br />Barone’s project, single-family with commercial retail land uses, would not include any of these
<br />uses. Operational odor emissions would be limited to odors associated with vehicle engine exhaust
<br />and trash receptacles. Solid waste generated by the proposed on-site uses would be collected by a
<br />contracted waste hauler, ensuring that any odors resulting from on-site waste would be managed
<br />and collected in a manner to prevent the proliferation of odors. Operational odor impacts would be
<br />less than significant.
<br />CONSISTENCY WITH BAAQMD CLEAN AIR PLAN
<br />The California CAA requires that air districts create a Clean Air Plan (2017 CAP) that describes how
<br />the jurisdiction will meet air quality standards. The most recently adopted air quality plan is the
<br />2017 CAP. The 2017 CAP does not include control measures that apply directly to individual
<br />development projects. Instead, the control strategy includes control measures related to stationary
<br />sources, transportation, energy, buildings, agriculture, natural and working lands, waste
<br />management, water, and super-GHG pollutants. A project that would not support the 2017 CAP’s
<br />goals would not be consistent with the 2017 CAP. On an individual project basis, consistency with
<br />BAAQMD quantitative thresholds is interpreted as demonstrating support for the CAP’s goals. As
