September 28, 2005Missoula, Montana1 Inter-RPO 2002 National Wildfire Emission Inventory - Results - by Air Sciences Inc. and EC/R, Inc. for the Inter-RPO Steering Committee

September 28, 2005Missoula, Montana2 Purpose Inventory of wildfire to include in RPO regional haze modeling for states and Tribes Inventory can be used to establish boundary conditions in regional haze modeling Inform RPOs on how to efficiently prepare technically robust inventories for fire Potentially provide the National Emission Inventory (NEI) with a nation-wide wildfire EI that has been developed with a consistent technical methodology (e.g. activity QC, FEPS)

September 28, 2005Missoula, Montana3 Building the Inter-RPO EI Incident Activity Data Collection –Must have acres, date, and location –QC’ed RPO data: MRPO, VISTAS, WRAP –Federal Reporting: WRAP’s ICS-209 & DOI 1202 database –State-level data requests –Perimeter to blackened acres adjustment of 0.66 * Data QC & Gap-filling –Geo-reference fires using county and TRS –GIS-based NFDRS fuel loading overlay –Regional-default NFDRS fuel loading –Drop events not meeting quality objectives * WRAP Inter-RPO acres will be smaller than “Phase II”

September 28, 2005Missoula, Montana4 Inter-RPO Enhancements Duplicate and Large Fire QC Checking –Large fires (> 10k acres) and complexes hand checked for double counting –GIS-script to flag for proximity of all fires > 100 acres: Closer than 10 km and occurring within 15 days 1000-hr and 10-hr Fuel Moisture Assignment –1000-hr GIS layers from WFAS / U.C. Berkeley –10-hr GIS layers created from WFAS WIMS archive –Overlay fire locations for day- specific moisture percent –FEPS moisture regimes defined by 1000-hr fuel moisture ranges

September 28, 2005Missoula, Montana5 FEPS Consumption and EFs Fuel Categories (1350 total) –RPO Region –NFDRS Fuel Model –Moisture Regime –Flaming/Smoldering FEPS runs evaluated for each fuel category –Total consumed used in emissions calculations –PM 2.5, PM 10, TSP, PMC, EC, OC, SO 2, NO X, VOC, CO, CH 4, NH 3

September 28, 2005Missoula, Montana6 Example Fuel Consumption Lookup NFDRS Fuel Model G is Short Needle (Heavy Dead)

September 28, 2005Missoula, Montana7 Inter-RPO Wildfire EI Acres Burned Tons PM 2.5 Note: WRAP Inter-RPO acres “blackened” is less than WRAP Phase II “perimeter” acres (5.27 million acres). 4.5 Mil Total 1.1 Mil Total

September 28, 2005Missoula, Montana15 Remaining Tasks and Deliverables Review of comments on draft report and delivery of final report Value added / lessons learned analysis and documentation. Examples: –Differences between WRAP Phase II new Inter-RPO –Recommendations for cost effective and high-quality improvements to build future inventories Application of FCC fuel loading to WRAP Phase II emission inventory Schedule: Review period (2 weeks) and final deliverables expected complete in 4 – 6 weeks
