Therefore, the project would not result in a <br />CO “hotspot” and no intersection-specific CO modeling is required. <br />a. Would the project conflict with or obstruct implementation of the applicable air quality plan? <br />The BAAQMD has adopted several air quality policies to reduce air emissions in the Basin. In April <br />2017, the BAAQMD adopted its final 2017 Clean Air Plan (BAAQMD 2017a). A project would conflict <br />with or obstruct implementation of the 2017 Clean Air Plan if it would result in substantial new <br />regional emissions not foreseen in the air quality planning process. The 2017 Clean Air Plan assumes <br />that development associated with general plans, specific plans, residential projects, and public <br />facilities will be constructed in accordance with population growth projects identified by the <br />BAAQMD. In effect, if a project is proposed in a city with a general plan that is consistent with the <br />Clean Air Plan (i.e., it does not require a general plan amendment) then the project would be <br />consistent with the Clean Air Plan. <br />The project does not involve residential uses and would not directly increase population. The <br />project is consistent with the site’s existing industrial land use and would not require a general plan <br />amendment. The project would not result in a substantial intensification the underlying mobile <br />emissions assumptions contained in the 2017 Clean Air Plan. Additionally, due to its relatively <br />modest net increase in size compared to the existing uses of the site, the project would not result in <br />a substantial unplanned increase in employment, regional growth in vehicle miles traveled, or <br />emissions. The current onsite developments do not have any stationary industrial sources that <br />require BAAQMD permits. The project would not add any stationary sources subject to BAAQMD <br />permit approval. Therefore, the project would not conflict with or obstruct implementation of the <br />2017 Clean Air Plan. Impacts would be less than significant. <br />LESS THAN SIGNIFICANT IMPACT <br />318
