LADCO Ozone TSD – 2015 O3 NAAQS Moderate Area Attainment Demonstration
LADCO prepared this Technical Support Document (TSD) to support the development of attainment demonstration state implementation plans (SIPs) for 2015 ozone (O3) National Ambient Air Quality Standards (NAAQS) moderate nonattainment areas (NAAs). The TSD includes an ozone trends analysis, air quality modeling platform description, base and future year emissions summary, chemical transport modeling evaluation, attainment testing, and source apportionment analysis. LADCO presents in this TSD modeling and analysis results for a 2016 base year projected to 2023.
