Technical Oversight Committee : Meetings & Calls

Workshop on Regional Emissions &
Air Quality Modeling Studies

July 29-30, 2008, Denver, CO

Agenda: PDF or DOC
Meeting Logistics

Purpose:

  1. Address plans for developing and updating regional emissions data and conducting modeling studies, and applying those data for the 2009-12 time frame;
    1. Identify strengths and weaknesses of existing WRAP and other emissions data collection support systems and processes;
    2. Determine key emissions sectors requiring further analysis;
    3. Discuss needs and capabilities for future regional modeling and analysis techniques (Eulerian, Lagrangian, receptor, inverse, others);
    4. Develop coordination with ongoing and planned State/Tribal/Local/Federal modeling activities;
    5. Discuss timing, effort, activities, and any needed changes in future projects by WRAP contractors; and
    6. Document results for work planning purposes & next steps
  2. Identify opportunities for supporting state, tribal, local, and federal air quality planning needs;
    1. Tracking improvements in visibility/reductions in regional haze;
    2. Analyzing source-receptor relationships for nonattainment areas;
    3. Analyzing source receptor relationships for attainment and unclassifiable areas;
    4. Quantifying welfare/ecosystem impacts for remote/rural areas; and
    5. Analysis and development of regional emissions reduction strategies to complement state, tribal, local, and federal air quality planning efforts
  3. Discuss needs, time frames, and costs for tracking and analysis.

Results: Report with key deliverables and projects needed in 2009-12 timeframe

Interactive Agenda

Tuesday, July 29th
8:00 am

Plenary - Welcome/Purpose/Introductions

8:30
  • Overview & WRAP Status Check: What are ongoing and emerging regional air quality issues – Tom Moore, WRAP staff PDF or PPT (1MB)
    • 2012 Regional Haze mid-course check/planning requirements
    • March 2008 Ozone NAAQS revision – designations/planning requirements/attainment plans
      • The July 15, 2008 Ozone White Paper entitled "Revised 8–Hour Ozone NAAQS & Implications for the Western States" previously posted, has been removed for additional analysis. From the workshop and through subsequent review and comment, the modeling results displayed need additional analysis and explanation. Comments about more complete analysis of monitoring results were also received. The July 15th white paper should NOT be quoted or cited. The 2nd edition of this White Paper will be available in early 2009.
    • December 2006 PM2.5 NAAQS revision – designations/planning requirements/attainment plans
    • Future actions by EPA to regulate Mercury
    • Review of/future revisions to the Primary & Secondary NAAQS
