Environmental Analysis March 2020 Page 29 term pollution; however, the Approved Project’s emissions of NOx would remain significant and unavoidable. The Approved Project would found to result in a less than significant impa ct to CO emissions (local air quality). The Certified EIR found that the Approved Project is consistent with the South Coast Air Quality Management Plan. The Initial Study for the Certified EIR determined that the Approved Project would not result in the significant amounts of objectionable odors or create an adverse effect. A less than significant impact would occur. 5.3.2 Impacts Associated with the Proposed Project Where available, the significance criteria established by the applicable air quality management district or air pollution control district may be relied upon to make the following determinations. Would the project: Environmental Issues Substantial Change in Project Requiring Major EIR Revisions Substantial Change in Circum-stances Requiring Major EIR Revisions New Information Showing New or Increased Significant Effects Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR No Impact a) Conflict with or obstruct implementation of the applicable air quality plan? x b) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard? x c) Expose sensitive receptors to substantial pollutant concentrations? x d) Result in other emissions (such as those leading to odors) adversely affecting a substantial number of people? x Methodology Urban Crossroads prepared a memorandum reviewing Air Quality and Greenhouse Gas Emissions for the Proposed Project (AQ/GHG Memo). The AQ/GHG Memo is contained in Appendix A. Emissions for the Proposed Project were calculated employing the California Emissions Estimator Model (CalEEMod) version 2016.3.2. Comments: a) Conflict with or obstruct implementation of the applicable air quality plan? Less Than Significant Impact/No Changes or New Information Requiring Preparation of an EIR. Air quality in Orange County is regulated by SCAQMD, which is the agency principally responsible for comprehensive air pollution control in the South Coast Air Basin (SoCAB). The SCAQMD develops rules and 5 - 83
