Section 4.0— Environniental Setting and Discussion of Impacts Objectionable Odors Odor impacts can result from siting a new odor source (e.g., landfills, asphalt batch plants, food processors, etc.) near existing sensitive receptors. The proposed project does not include new uses that would emit odors. (Less Than Significant Impact) 4.3.3.4 Short -Terns Construction Air Quality Impricts from the Proposed Project (Checklist Questions 2-5) Construction activities would generate dust and equipment exhaust on a temporary basis. Project construction is estimated to take approximately five months to complete. Criteria Pollutants The BAAQMD CEQA Air Quality Guidelines identify the size of land use projects that could result in significant air pollutant emissions. The BAAQMD screening level for criteria air pollutant emissions during construction of an elementary school is 277,000 sf or 3,904 students. The proposed project includes construction of a two-story modular classroom building, a Kindergarten modular classroom, a public restroom, and other various additions and improvements to the project site. The proposed improvements total approximately 17,200 sf of building space and would increase student capacity at the school by 220 students. The project is below the BAAQMD screening levels for construction criteria air pollutants and, therefore, would not result in a significant temporary construction criteria air emissions impact. (Less Than Significant Impact) Toxic Air Contaminants Most of the construction activities would occur during the elementary school spring and summer breaks, when school is not in session. The nearest sensitive receptors to the project site are the residences located immediately north and south of the project site (refer to Figure 2.2-3). Health risks from TACs are a function of both concentration and duration of exposure. Construction of the proposed project would take approximately five months to complete, beginning in February 2017 and ending in July 2017. The new classroom buildings would be modular and, therefore, major components would be constructed off-site prior to being moved on-site. Grading for the modular buildings and associated improvements would occur intermittently to construct building pads and set foundations. The use of heavy diesel equipment on the site would be minimal given the construction method and relatively short construction schedule. Because construction activities would be minimal, truck traffic to and from the site would also be intermittent and of brief duration. As described below in MM AIR -1, the project would incorporate BAAQMD-recommended best available control measures to reduce fugitive dust during construction. This measure would also help to reduce construction TACs. Sensitive receptors in the project area, including nearby residents and children on the project site, would not be exposed to substantial levels of TACs during project construction activities.
