APPENDIX A2: FIRST WORKSHOP DISCUSSION SUMMARY 
During the Santa Fe workshop, participants raised and discussed the following concerns, 

questions, preferences, and recommendations: 

For the emissions data needs, reporting and tracking requirements of the EDMS, 

• It is important to decide who would be the primary user of the EDMS (planners, Scientists, 

etc.). 

• The EDMS should be designed in a modular fashion, including six (6) major source modules: 

point, area, fire, mobile, biogenic, and windblown dust sources. It should implement the 

reporting and tracking requirements of §309 first (Phase I), then §308 and other requirements 

and regulations (Phase II). 

• The EDMS inventory should focus on actual emissions rather than potential. 

• STL should submit data to WRAP EDMS and WRAP would get additional data from NEI. 

• The minimum spatial and temporal resolution of the emissions data should be county and 

annual respectively. 

• WRAP can submit data directly to NEI for the RHR reporting Requirements. 

• Visibility impairing pollutants are the working priority, but the system should accommodate 

inclusion of other pollutants in the future. 

• Descriptive source parameters and activity data should be included in the EDMS. 

• WRAP and EPA can provide Data international emissions. 

For the Data QA/QC, 

• The EDMS should incorporate automated QA/QC functionality to check submission format 

and content. 

• WRAP should consult with the submitting agency before modifying any data points. 

• The EDMS should include metadata and version control for all data submitted, reported that 

would be certified by a database administrator (DBA). 

For the GIS Requirements, 
• GIS requirements were not specifically discussed. However, the Fire Emissions Joint Forum 

requested ESRI formatted data and the ability to print multiple sized maps from the webbased system because of the previous experience using that software. 

For the User Preferences requirements, 

• The EDMS should have a mixed level of access by the public with protected functionality 

• The EDMS should accept NEI formatted submissions and produce NEI formatted exports. 

This would allow an easy integration with the TEISS system and easy coordination with STL 

submission to EPA. 

For the Training options, 

• WRAP should provide training for consistent emissions factors 

• WRAP should provide on-line user manual 

• WRAP should provide hands-on training / help desk 

For the Physical Location option, 

• The location of the system was not specifically discussed. 

During the Santa Fe workshop, individual forums also provided their group perspective on the 

following issues. 

For the emissions data needs, reporting and tracking requirements of the EDMS, 

• The EDMS should include sub-modules for emission models. 

• Trade associations and industry might also submit fire emissions data. 

• Modeling, monitoring, and Fire Forums requested daily/hourly temporal resolution. 

• Some forum members felt that the EDMS should include emissions calculation and 

emissions projection functionality. 

For the User Preferences 

• The Modeling Forum requested SMOKE input formatted exports.
