L S A FAIRVIEW BRIDGE REPLACEMENT AND STREET IMPROVEMENTS (9TH STREET TO 16TH STREET( PROJECT INITIAL STUDY/MITIGATED NEGATIVE DECLARATION SANTA ANAL CALIFORNIA MAY 2020 As discussed above, increase in traffic capacity would increase average vehicle speeds and reduce the average vehicle delay during peak -hour traffic, both of which would reduce the rate of vehicle emissions. Therefore, the proposed Project would result in a beneficial impact to regional and local air quality. As such, the proposed Project would not result in an increase in air pollution compared to existing conditions. Therefore, sensitive receptors would not be exposed to substantial pollutant concentrations during Project operation. d. Would the project result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? Less Than Significant Impact. SCAQMD's CEQA Air Quality Handbook identifies various secondary significance criteria related to odorous air contaminants. Substantial odor -generating sources include land uses such as agricultural activities, feedlots, wastewater treatment facilities, landfills, or heavy manufacturing uses. The proposed Project does not include any such uses or activities that would result in other emissions such as those leading to odors. Some objectionable odors may emanate from the operation of diesel -powered construction equipment during construction of the proposed Project that could be noticed by people adjacent to the construction area. However, these construction odors would be limited to the construction period, would disperse quickly, and would not adversely affect a substantial number of people. Therefore, construction impacts would be less than significant, and no mitigation is required. The proposed Project would consist of road widening and bridge replacement, which would not produce other emissions leading to odors that would adversely affect a substantial number of people. Project operation impacts would be less than significant, and no mitigation is required. 3.3.3 Mitigation Measures Mitigation Measure AQ-1 Construction Emissions Control. The Construction Contractor will adhere to the following procedures during construction and will provide the City of Santa Ana (City) Public Works Director or designee with documentation that these procedures were implemented during construction activities: • The contractor will adhere to the Greenbook (2018 or most current) specification: Section 3-12.2 Air Pollution Control. The Contractor will not discharge smoke, dust, equipment exhaust, or any other air contaminants into the atmosphere in such quantity as will violate any federal, State, or local regulations. The contractor will also abate dust nuisance by cleaning, sweeping and spraying with water, or other means as necessary. • The contractor will adhere to the Caltrans Standard Specifications for Construction, Sections 14.9-01, 14.9-02, 14- 9.03, 18-1.02C, and 18-1.03 (or Greenbook [2018 or most current] equivalent specifications).
