1. 1 Fire Emissions Inventories (almost) Closeout -- Ph IV Projections – Fire Emissions Joint Forum Meeting Spokane, WA Day 1 – 1015a part A Dave Randall Air Sciences Inc.

2. 2 Outline Update on where we are in the project. Viewing the data with air quality planning in mind. –Which suite(s) should the FEJF put in the queue for modeling?

3. 3 Phases of Fire EIs Phase II (historical 2002) Baseline (Phase III) (nominal 2000-2004) Projections (Phase IV) (nominal 2018) Activity Scenarios for each fire type Less Likely More Note: The PLANNING inventories (Phase III & IV) are unique EI’s…unique from each other AND unique from Phase II

4. 4 Anticipated 2018 Activity Levels (Acres) Fire-typeLessLikelyMore WF + WFU 4.7 MM 7.0 MM Rx (broadcast + piles) 1.0 MM2.0 MM3.7 MM Ag1.7 MM NFR1.3 MM

5. 5 Air Quality Planning Fire EI Suites

6. 6 Where are we on the project? Base-Case Planning Fire Files (Ph III) delivered (PT files for modeling). Projection Planning Fire Files (Ph IV) generated and ready for posting (PT files for modeling). Projection Tool developed and tested in- house. Finalizing documentation.

7. 7 What still remains to be done? Decision on NIF format for projection files. –Recommend NOT preparing these files at this point. Decision on what Fire/Air Quality Planning suites to put in queue for RMC modeling. Final Postings and Documentation. Post Projection Tool.

8. 8 2 Mistakes NAT/ANTH assignment method –Ph III files delivered with “old” method (NFDRS based). Alternative method (that we put through the Strawman process) was to use FCCS and FRCC to categorize events. –To keep Ph III and Ph IV comparable, we’ve prepared Ph IV using the “old” method.

9. 9 Nat/Anth Assignment (Based on PH II [2002] Fire Data) FCCS-method Total acres (Phase II Prescribed data) of FCCS fuel models assigned ANTH: 323K –214K acres > 7 tons/acre –30.7K Tons of PM2.5 Total acres (Phase II Prescribed data) of FCCS fuel models assigned NAT: 326K –240K acres < 15 tons/acre –50.1K Tons of PM2.5 NFDRS-method Total acres (Phase II Prescribed data) of NFDRS fuel models assigned ANTH: 301K –235K acres > 7 tons/acre –39.7K Tons of PM2.5 Total acres (Phase II Prescribed data) of NFDRS fuel models assigned NAT: 348K –243K acres < 15 tons/acre –41.0K Tons of PM2.5

10. 10 2 Mistakes (continued) –This issue involved Baseline (Ph III) events that were missing emissions because they were missing smoldering records. SAME MISTAKE made in the Baseline and Baseline Control EI files. Approximate Impact to EIs: Wildfire PM2.5 Tons: 19,147 (4% of total WF emissions) WFU PM2.5 Tons: 1.579 (2% of total WFU emissions) –Recommended Remedy – Document the issue; Fix the problems in the Projections (Ph IV); Leave Baseline (Ph III) as is.

11. 11 Ph IV Data Review with Air Qualty Planning in Mind Devise a couple of Threshold Questions we’d like to have answered by RMC Modeling. Review the data to determine which Air Quality Planning Suite(s) best answer that question. The best focus appears to be on the difference between Base-Case and Max- App of RX fire.
