Technical Projects Update
WRAP Board Meeting
Salt Lake City, UT
November 10, 2004
Presentation Topics
Technical Projects – 2004 Accomplishments Attribution of Haze Dust Emissions Fire Modeling Monitoring & Reporting Stationary Sources – already covered Tribal Data Development
Attribution of Haze Project
Attribution of Haze Workgroup: Phase 1 Draft report – present at SSJF/IWG
meeting 12/14 Review and comment - Final report late 1/05 Uses integrated “weight of evidence” analysis of
3 major data types (monitoring, modeling, emissions inventories)
Determines geographic origins and source type contributions to impairment at all federal and tribal Class I areas
Attribution of Haze Project
Attribution of Haze Workgroup: Outcomes:
Phase 1 report - Identifies key source types and regions for states and tribes to address in 2007 plans
Provide early input to guide policy development Template for Phase II attribution of haze project
to assess visibility changes from 2018 control strategies
Attribution of Haze Project
2002 Annual SO2 Emissions by
Modeling Grid Cell (tons/year)

Class I area report
Dust Emissions Projects
Dust Emissions Joint Forum: Causes of Dust Haze in the WRAP
Region (DRI) Preliminary categorization – monitoring sites
where dust was the principal cause of haze on a worst visibility day
Transcontinental Events Windblown Dust Events (Local and
Regional) Wildfire Events influencing apparent dust
concentration
Dust Emissions Projects
Dust Emissions Joint Forum: Windblown Dust Emissions Model (Regional
Modeling Center) Phase 2 of project – added several improvements Testing of results to improve performance compared to
monitor data
Analysis of the Fine Fraction of Particulate Matter in Fugitive Dust (RFP released 10/21)
Evaluation and Implementation of a Dust Definition for the WRAP (RFP released 10/28)
Emissions Forum Projects
Emissions Forum: Emissions Data Management System
State/tribal/local 2002 inventories loaded Independent beta testing, additional functions
being added Website on-line 12/04
Alaska projects Emissions inventories for representative Alaska
native villages Aircraft emissions
Emissions Forum Projects
Emissions Forum: Acquired improved Canada [2000] & Mexico
[1999] emissions inventories Mobile source emission inventories update
project scope Supporting access to completed projects by
the Sources In & Near Class I areas Forum Final micro-inventories for emissions in 8 parks Final characterization of emissions near all
western Class I areas (based on1996 data, to be updated with 2002 data)
Fire Emissions Projects
Fire Emissions Joint Forum: 2002 national wildfire emissions (WRAP lead) 2002 wild, ag & prescribed fire inventories
[extensive QA/QC for activity data with states/tribes/FLMs]
** review underway now ** Final 2002 inventories - 12/04 Tested/improved fire emissions estimation tools
Fire Emissions Projects
Fire Emissions Joint Forum: Developed scope of work for planning inventories
2000-04 baseline period 2018 projection year scenarios
Developed approach to quantify Emissions Reductions Techniques adopted by §309 states
Fire Emissions Sensitivity modeling analyses
Modeling Technical Projects
Air Quality Modeling Forum: Multiple simulations by Regional Modeling
Center Implemented improved data and tools
Meteorological model [MM5] Emissions from other RPOs Improved emissions for ammonia, biogenics,
and windblown dust Geographic source apportionment work
for AoH project
Modeling Technical Projects
Air Quality Modeling Forum: Alaska modeling
Developed MM5 modeling protocol Starting sensitivity runs using Alaska emissions data Deliverables in April 2005
Training Provided as part of AoH project Exploring other options to provide more
training and access to results Fire Sensitivity Modeling
Assess modeled impact of changes in fire inventories

Monitoring & Reporting Projects
Ambient Monitoring & Reporting Forum: VIEWS database/webpage – inter-RPO
project Moved to direct EPA funding on behalf of
RPOs during 2004 RPOs have requested that EPA fund starting
in 2006 Causes of Haze Assessment
Extensive database of monitoring and meteorological data online
Back trajectory regression modeling analyses identify source regions for AoH project
Monitoring & Reporting Projects
Ambient Monitoring & Reporting Forum: Natural Haze Levels Assessment
Inter-RPO project, WRAP lead Analyze which natural emissions species are
sensitive to changes, and by how much Work underway, results available Spring 2005
Review of regional haze light extinction algorithm by IMPROVE Steering Committee
Tribal Data Development Projects
Tribal Data Development Workgroup: Implement and support use of TEISS tool Developing emissions inventories for
stationary sources on tribal lands (coordinated with Stationary Sources and Emissions Forums project)
Causes of Haze Assessment for tribal lands
