1. 2005 NEI - Changes

2. 2 A Call for Change Address external critiques –National Academy of Sciences report –Clean Air Act Advisory Committee report –NARSTO’s Emission Inventory Assessment Address internal critiques –EPA, S/L/T’s, RPOs Meet new challenges of air quality management programs –Multi-pollutant effects –Increased Spatial and Temporal Resolution Provide better quality and more timely data

3. 3 A Collaborative Effort Communication, Consensus-building, and Decision-making by EPA, S/L/Ts, RPOs, other stakeholders –Create a more efficient process to develop the NEI –Produce an NEI that is more accurate, timely and transparent –Distribute a product that is useful to the entire Air Quality community

4. 4 Now What? When?

5. 5 Why change our plans for developing the 2005 NEI? 2008 is the target year for reengineered process 2005 NEI and reengineering competing for resources 2005 Process would be very similar to 2002 Less regulatory need for a 2005 NEI Redeploy staff time and contract dollars to reengineering Time already spent in planning for 2005 NEI will be useful for reengineering

6. 6 How will we develop the 2005 NEI? 2002 NEI as the basis for 2005 NEI –Based on 2002 data, except –Highest value-added adjustments for EGU and mobile sources –Seek information on large point source closures –Investigate a low-cost method to include actual 2005 wildland emissions –S/L CERR submittal data will not be included in the NEI 2005 Complete by early 2007 – before CERR submittals are even due

7. 7 What about the CERR submittals? CERR Submittal still required by June 2007 –Major Points at minimum submitted by State/Locals –S/Ls can accept NEI’s Nonpoint and Mobile Sector Estimates for CERR Submittals in NIF 3.0 or other documented format (NIF 4.0 suspended)

8. 8 How Will EPA Use the CERR Submittals? Post S/L/T data "as received" on CHIEF EPA will analyze data for opportunities to improve process for the future This Proposal is for 2005 Only

9. 9 Benefits of this proposal EPA and S/L/T can jointly focus on long term strategy for improving EIs More opportunities to provide input to the NEI reengineering Reduces resources for EPA and S/L/Ts –Continued use of NIF 3.0, or alternative format –Less re-engagement on data correction

10. 10 NEI and Regulatory Reporting CERR Consolidates regulatory requirements for S/Ls to report criteria data to EPA for S/Ls periodic emission inventories, NOx SIP Call reporting, and large point sources 2005 NEI EPA EFIG uses CERR data plus other sources for completeness to compile integrated national inventory for criteria and HAP emissions with S/L review SIP EIs Criteria data and documentation as input to the air quality modeling for attainment strategy, the public review process, and rate of progress tracking (ROP)
