Environmental Analysis <br />term pollution; however, the Approved Project's emissions of NO. would remain significant and unavoidable. <br />The Approved Project would found to result in a less than significant impact to CO emissions (local air quality). <br />The Certified EIR found that the Approved Project is consistent with the South Coast Air Quality Management <br />Plan. <br />The Initial Study for the Certified EIR determined that the Approved Project would not result in the significant <br />amounts of objectionable odors or create an adverse effect. A less than significant impact would occur. <br />5.3.2 Impacts Associated with the Proposed Project <br />Where available, the significance criteria established by the applicable air quality management district or air <br />pollution control district may be relied upon to make the following determinations. Would the project: <br />Less Than <br />Significant <br />Substantial <br />Impact/No <br />Substantial <br />Change in <br />New <br />Changes or <br />Change in <br />Circum- <br />Information <br />New <br />Project <br />stances <br />Showing New <br />Information <br />Requiring <br />Requiring <br />or Increased <br />Requiring <br />Major EIR <br />Major EIR <br />Significant <br />Preparation of <br />Environmental Issues <br />Revisions <br />Revisions <br />Effects <br />an EIR <br />No Impact <br />a) Conflict with or obstruct implementation of <br />the applicable air quality plan? <br />X <br />b) Result in a cumulatively considerable net <br />increase of any criteria pollutant for which <br />the project region is non -attainment under <br />X <br />an applicable federal or state ambient air <br />quality standard? <br />c) Expose sensitive receptors to substantial <br />pollutant concentrations? <br />X <br />d) Result in other emissions (such as those <br />leading to odors) adversely affecting a <br />X <br />substantial number of people? <br />Methodology <br />Urban Crossroads prepared a memorandum reviewing Air Quality and Greenhouse Gas Emissions for the <br />Proposed Project (AQ/GHG Memo) dated April 16, 2020. The AQ/GHG Memo is contained in Appendix <br />A. Emissions for the Proposed Project were calculated employing the California Emissions Estimator Model <br />(CalEEMod) version 2016.3.2. <br />Comments: <br />a) Conflict with or obstruct implementation of the applicable air quality plan? <br />Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR. <br />Air quality in Orange County is regulated by SCAQMD, which is the agency principally responsible for <br />comprehensive air pollution control in the South Coast Air Basin (SoCAB).
