## Completed Activities

- 1996 Base Year Regional Emission Inventory
- 2018 Projections Regional Emission Inventory
- Base Case
- §309 Annex Milestones Case
- §309 Command & Control BART
- §309 Command & Control BART (w/ Uncertainty)

## Long Term Issues

- WRAP Regional E.I. Improvements
- Ammonia
- Fugitive Dust
- Temporal Allocation & Chemical Speciation

## Completed Activities:'96 Base Year E.I.

- Revised ’96 EI Completed Fall 2002
- 13 state WRAP Region (AZ, CA, CO, ID, MT, ND, NM, NV, OR, SD, UT, WA & WY)
- 9 Bordering CENRAP States (NB, KA, OK, TX, MN, IA, MO, AR, LA)
- 7 visibility related pollutants (VOC, NOx, CO, SO2, PM10, PM2.5 & NH3)
- 5 Main Source Categories
- Point
- Area
- Mobile (both On-Road & Non-Road Mobile)
- Fire (Wildfire, Wildland Prescribed Fire & Agricultural Fire)
- Road Dust (both Paved & Unpaved)

## WRAP Modeling Domain

## Completed Activities:'96 Base Year E.I.

- Point & Area databases are available on the WEB:      http://www.wrapair.org/forums/ef/index.html
- Summaries are available for all source categories              (totaled by State & by County)

## Completed Activities:2018 Projections

- Covers the same Pollutants, Source Categories & Geographic Area as the ’96 EI
- The Point & Area Source Report is currently on the previously noted WRAP website, under the “Documents” page.
- Other Source Category projections (mobile & fire) are available as spreadsheet summaries

## Long Term Issues:WRAP EI Database Development

- the WRAP has struggled in this area
- Web based display of data for Public Info.
- Incorporate GIS for misc. §309 tracking rqmnts (CAC’s, Fire, Mobile, Road Dust)
- Proper input/output formats (NEI rqmnts, RPO Data Exchange Protocol effort)
- Decided to complete a “Needs Assessment”
- RFP will be issued shortly

## Long Term Issues:WRAP Regional EI Guidance

- the WRAP intends to obtain the necessary data for a “dynamic” EI System, from the WRAP States, Tribes & Local Agencies
- ˆthe Emission Forum has budgeted future monies to provide _Data Protocol_ & _User Training_ to these State, Tribal & Local agencies

## Long Term Issues:WRAP EI Improvements: NH3

- The University of California @ Riverside provide the EF with a proposal in May ’02
- Project will “incorporate NH3 emission algorithms into a GIS based model”
- Develop Environmental & Activity Data for:
- Soils/fertilizers, Livestock temporal NH3, domestic/composting sources
- Develop a “fleetwide correction factor” for mobile source NH3
- WRAP will move forward with $85K project, but will specifically coordinate w/ CENRAP & other RPO’s

## Long Term Issues:WRAP EI Improvements: Dust

- no “windblown fugitive dust” in current EI
- WRAP contracted w/ ENVIRON to develop a dust module for modeling, and to compile a 1996 fugitive dust PM10 & 2.5 EI using this module
- Uses emission factors from wind tunnel studies, along with extensive categorization of WRAP region lands (_[Empirical Method for Determining Fugitive Dust Emissions from Wind Erosion of Vacant Land](http://www.wrapair.org/forums/DEJF/workdocs/2002-06_Empirical%20Method%20proposal.doc)_ methodology is on the EF Dust page & RFP is available under “WRAP Project Status”
- Spring 2003 Report – will notify RPO’s of Report Presentation by ENVIRON

## Long Term Issues: WRAP EI Improvements for Temporal Allocation/ Chemical Speciation

- WRAP is concerned that temporal allocation & chemical speciation factors in the SMOKE emission processor, may not be accurate for western sources
- The WRAP Regional Modeling Center @ UCR will review the SCC’s currently in SMOKE for appropriateness to western sources
- Then WRAP will look at sources representing the top “X%” of emissions for accuracy of speciation & temporal allocation profiles
