Hana Japan Restaurant Project <br />Initial Study/Mitigated Negative Declaration <br />19 <br />May 2025 <br />State and federal AAQS within the SFBAAB. Adopted BAAQMD rules and regulations, as <br />well as the thresholds of significance, have been developed with the intent to ensure <br />continued attainment of AAQS, or to work towards attainment of AAQS for which the area <br />is currently designated nonattainment, consistent with applicable air quality plans. The <br />BAAQMD’s established significance thresholds associated with development projects for <br />emissions of the ozone precursors reactive organic gases (ROG) and oxides of nitrogen <br />(NOX), as well as for PM10 and PM2.5, expressed in pounds per day (lbs/day) and tons per <br />year (tons/yr), are listed in Table 1. By exceeding BAAQMD’s mass emission thresholds <br />for ROG, NOX, PM10, or PM2.5, a project would be considered to conflict with or obstruct <br />implementation of the BAAQMD’s air quality planning efforts. <br /> <br />Table 1 <br />BAAQMD Thresholds of Significance <br />Pollutant <br />Construction Operational <br />Average Daily <br />Emissions <br />(lbs/day) <br />Average Daily <br />Emissions <br />(lbs/day) <br />Maximum Annual <br />Emissions <br />(tons/year) <br />ROG 54 54 10 <br />NOx 54 54 10 <br />PM10 (exhaust) 82 82 15 <br />PM2.5 (exhaust) 54 54 10 <br />Source: BAAQMD, CEQA Guidelines, May 2017. <br /> <br />The proposed project’s construction and operational emissions were quantified using the <br />California Emissions Estimator Model (CalEEMod) software version 2022.1.1.29 – a <br />statewide model designed to provide a uniform platform for government agencies, land <br />use planners, and environmental professionals to quantify air quality emissions, including <br />GHG emissions, from land use projects. The model applies inherent default values for <br />various land uses, including construction data, trip generation rates, vehicle mix, trip <br />length, average speed, etc. Where project-specific information is available, such <br />information should be applied in the model. All CalEEMod results are included as <br />Appendix A to this IS/MND. <br /> <br />The proposed project’s estimated emissions associated with construction and operations <br />are presented and discussed in further detail below. A discussion of the proposed project’s <br />contribution to cumulative air quality conditions is provided below as well. <br /> <br />Construction Emissions <br />According to the CalEEMod results, the proposed project would result in maximum <br />unmitigated construction criteria air pollutant emissions as shown in Table 2. As shown in <br />the table, the proposed project’s construction emissions would be below the applicable <br />thresholds of significance for ROG, NOx, PM10, and PM2.5. Construction activities <br />associated with the proposed project would include the export of 22,580 cubic yards (CY) <br />during grading, as well as the development of a single story, 6,445-sf teppanyaki <br />restaurant and associated on- and off-site improvements. <br /> <br />All projects under the jurisdiction of the BAAQMD are required to implement all BAAQMD <br />Basic Construction Mitigation Measures (BCMMs), which include the following: <br /> <br />1. All haul trucks transporting soil, sand, or other loose material off-site shall be <br />covered.
