Why are we here?

1. Why are we here? • Vision for the Future • Better process and tools to build the NEI • Develop collaborative approach to building the NEI • How does the agenda tie to vision • Reengineering the future of the NEI • Learn from the current process and tools (2002) • Advance proposal for 2005 • Get your input on vision for the future (Reengineering and brainstorming)

2. The National Emission Inventory Re-engineering a New Process

3. Overview • Current NEI Process • Challenges of the Current Process • What is Reengineering? • Why Reengineer? • Goal for the Project • Project Schedule • Project Information

4. Current NEI Process • EPA creates a preliminary inventory for comment and review • Data are submitted by State, Local and Tribal agencies using CDX • EPA processes the data and creates a draft NEI • State, Local and Tribal agencies review and comment on the draft NEI • EPA resolves issues and incorporates comments • EPA releases the final NEI

5. Where We Are Today: NEI Process Diagram EMAD’s ftp server Envirofacts ( OEI ) ISEG – NEON – Data retrieval by ControlNET FHWA data States and others Intranet Phoenix FLM databases query tool AirDATA – Standard reports for the public Mobile / Non - point Source OTAQ data contractor database EIG’s Oracle Data warehouse – NEI Server Query / map access EPA and by OAQPS States Contractors ESD data EPA Chief web site CDX EPA - generated EPA staff - model runs NATA CAMD data Point Source contractor Personally held database summary tables TRI Air quality Contractor - modelers FRS generated Historic data EIA data model runs Custom reports / files for internal / external Contractor – Augment requestors IPM outputs Data Sources Submissions Database Additional Data Sources Data outputs

6. Challenges of the Current Process • It’s a complex process • Accepts multiple file types • Relies on multiple data sources: whose data is correct? • Lacks a standard for review and comment • Requires too much time to format data and process corrections

7. Challenges of the Current Process (cont’d) • Start from scratch each cycle • Takes three years to create an emissions inventory • Limited transparency • Inconsistent/limited access to NEI data

8. What is Reengineering? Business Process Reengineering • Review current business processes and data systems • Identify areas of change • Implement fundamental improvements for all stakeholders involved in the NEI process • Make the process more efficient • Leverage technology

9. Why Reengineer? • To address external critiques of emissions inventories • National Academy of Sciences report • Clean Air Act Advisory Committee report • NARSTO’s Emission Inventory Assessment • To address internal critiques of emissions inventories – EPA, S/L/T, RPOs • To provide better quality and more timely data

10. Why Reengineer? (cont’d) • To take advantage of new technology • To build transparency into the process • To provide enhanced access to the data • To ensure the NEI provides value to the entire EI community as the premier emissions inventory • To incorporate lessons learned

11. Goal of the Reengineering Project Build a more accurate emissions inventory by creating an efficient and transparent process

12. Achieving the Goal:The Emissions Inventory System (EIS) • Enhanced quality assurance as part of the submission process • Streamlined data reporting requirements • Consistent file transmission method • Timely on-line access to draft inventory data • Standard review and comment method • Improved access to data

13. Where We Want to Go:Future NEI Process Diagram

14. Project Schedule Preliminary schedule • 2005-2006: Define the new process and system • 2006–2007: Design and development • 2008: Test the new process and system • 2009: Launch the new process and system for the 2008 emissions inventory
