1. WRAP Activities Overview §308 Technical Work Outline June 3, 2003

2. Development of an Emission Data Management System (EDMS) To store and analyze emissions data to be contributed by states, tribes, and local air pollution control agencies –In support of future state and tribal regional haze implementation plan development, along with –Implementation of the §309 emissions tracking and reporting requirements of the regional haze rule

3. Development of an Emission Data Management System (EDMS) Conceptually, the system is to be capable of receiving and storing emissions data in EPA-compliant emissions reporting formats commonly used by various agencies and sources: –With little or no additional effort –Producing user-specified reports –Performing user-selected quality control and assurance tests –Allowing data queries and graphic display, and –Presenting this information in geographic information system (GIS) format, all via an internet web page

4. Development of an Emission Data Management System (EDMS) Needs Assessment project –To clearly understand what information, formats, and output capabilities ought to be included in this system, as well as what user needs may be –EA Engineering, Science and Technology (EA) is under contract with the WRAP Emissions Forum –2 interview workshops Santa Fe on March 20th Denver on May 7th EA also developed a web-based questionnaire to gather opinions about needs and requirements for the WRAP EDMS Reports to be completed in June and July 2003

5. Strategic Plan

9. Simplified Apportionment Process Phase I Phase II

10. Technical Process – occurs in Phase I and II Analyze Source Contributions By: Modeling and Monitoring Forums Using: Data from baseline and prior years and 2018 (for modeling analysis) Outputs: Periodic reports from each forum summarizing geographic and source category contributions to each Class I area by: 1) Grid cell and/or source region, 2) Aerosol species, and 3) Source classification code.

11. Technical Analysis Process – occurs in Phase I and II Reconcile and Synthesize Results By: A periodically-convened work group under TOC oversight Using: 1) Modeling results 2) Monitoring results (causes of haze reports) 3) Emission inventories and external data sources and studies Outputs: Periodic assessments integrating the information sources above into qualitative and quantitative summaries of geographic and source category contributions (including characterizations of uncertainty, confidence, and natural/anthropogenic contributions) to each Class I area or group of areas.

12. TOC Source Apportionment Process Need to develop protocol and schedule Identify need for contractor support Focuses importance on the need for Forums to: –Meet milestone dates –Provide ongoing status on the content of deliverables
