No No No No Source:CalEEMod version 2022.1. Refer to Attachment A for Model Data Outputs. Notes: Emissions taken from the year and season,summer or winter,with the highest outputs. Table shows that the emissions of these pollutants during construction would not result in significant concentrations of pollutants at nearby sensitive receptors.Therefore,significant impacts would not occur concerning LSTs during construction activities. LSTs were developed in response to SCAQMD Governing Boards' Environmental Justice Enhancement Initiative.The SCAQMD Environmental Justice Enhancement Initiative program seeks to ensure that everyone has the right to equal protection from air pollution. Therefore, significant impacts would not occur concerning LSTs during construction activities. 4.3.3 Project Operations-Generated Criteria Air Quality Emissions The Project proposes to widen Fairview Street from two lanes to three lanes in both directions from 17`" Street to Trask Avenue in order to accommodate existing and projected traffic volumes. The Proposed Project itself would not generate automobile trips,a source of air pollutant emissions, but would instead accommodate more efficient vehiculartravel within the City of Santa Ana. The Project would not include the provision of any new permanent stationary source of criteria air pollutant emissions.Thus,the Project, by its nature, would not generate quantifiable criteria emissions from Project operations. 4.4 Biological Resources The Project Site is located in a highly developed portion of the City of Santa Ana. The site is not in the vicinityof any natural orwildlife area.The Project does not include tree removal. No biological resources would be disturbed as part of the Proposed Project. In November 2024 ECORP conducted a literature review of sensitive biological resources including a search of the USFWS Informationfor Planning and Consultation(IPaC) within the Project Site boundaries (Appendix B).ECORP biologists conducted a desktop review of aerial imageryof the Project Site to assess the presence of sensitive habitats or habitats that could support special-status plant and/or wildlife ECORP Consulting, Inc. 10 January 2025 Fairview Street Widening Project 2024-088.03 9-22
