Would the project conflict with or obstruct implementation of the applicable air quality plan? No Impact. Consistency with the 2016 AQMP for the Basin would be achieved if a project is consistent with the goals, objectives, and assumptions in the respective plan to achieve the federal and State air quality standards. Per the SCAQMD California Environmental Quality Act Air Quality Handbook,' there are two main indicators of a project's consistency with the applicable AQMP: (1) whether the project would increase the frequency or severity of existing air quality violations or cause or contribute to new violations, or delay timely attainment of air quality standards or the interim emission reductions specified in the 2016 AQMP; and (2) whether the project would exceed the 2016 AQMP's assumptions for 2030 or yearly increments based on the year of project buildout and phasing. For the proposed Project to be consistent with the AQMP, the project should be listed in the RTP/SCS. The proposed Project is listed in the financially constrained list of projects in the 2016 RTP/SCS under RTP ID: 2AO704 and listed in the Federal Transportation Improvement Program (FTIP) under ID# 0RA170007. The 2017 FTIP Consistency Amendment 17-18 was approved by SCAG on February 23, 2018, and by the Federal Transit Administration (FTA)/Federal Highway Administration (FHWA) on March 26, 2018. The design concept and scope of the proposed Project is consistent with the project description in the 2016 RTP and 2017 FTIP and the "open to traffic" assumptions of SCAG's regional emissions analysis. Therefore, the proposed Project would not conflict with or obstruct implementation of the AQMP, and no impacts would occur. b. Would the project 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? Less Than Significant with Mitigation Incorporated. The SCAQMD is currently designated as nonattainment for the federal and State standards for 03 and PM2.5. In addition, the Basin is in nonattainment for the State PM10 standard. The SCAQMD's nonattainment status is attributed to the region's development history. Past, present, and future development projects contribute to the region's adverse air quality impacts on a cumulative basis. By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to, by itself, result in nonattainment of ambient air quality standards. Instead, a project's individual emissions contribute to existing cumulatively significant adverse air quality impacts. If a project's contribution to the cumulative impact is considerable, then the project's impact on air quality would be considered significant. 6 South Coast Air Quality Management District. 1993.
