Regional Haze, Dust, and New Mexico

1. Regional Haze, Dust, and New Mexico Developing a State Implementation Plan for Dust in the Salt Creek Wilderness Area, New Mexico

2. Project Objectives • Apply and integrate the tools developed by the Dust Emission Joint Forum for the purpose of developing a pilot regional haze SIP for dust at a Class I area. • Provide feedback to the Forum to refine the tools where necessary. • Provide a template/protocol for applying the WRAP tools which may be used at other Class I areas

3. Tools • Definition of Dust • Fine Fraction of Fugitive Dust • Causes of Dust Analysis • Fugitive Dust Emissions from Wind Erosion • Fugitive Dust Handbook • CMAQ Air Quality Modeling • Weight of Evidence “Checklist”

4. Supplemental Analysis • Identification of Source Areas Affecting Dust Concentrations at the Salt Creek, New Mexico • Continuation of DEJF Causes of Dust Analysis • Application of the WRAP's Draft Definition and Categorization of Dust to the Salt Creek Class I Area, A Case Study • Continuation of DEJF Dust Definition

5. Salt Creek Wilderness Area

6. Salt Creek Wilderness Area • A 9,621 acre area located within the Bitter Lake National Wildlife Refuge in southeastern New Mexico. • Located 10 miles east of Roswell, New Mexico • The Class I Area is characterized by dry creek beds, gypsum sinkholes, and sand dunes.

7. Site Visit Salt Creek • The DEJF workgroup for the pilot study visited the Salt Creek Wilderness in March of 2006

8. Site Visit to Salt Creek • Developed pilot project outline • Strawman/Outline • Determined emission inventory area • 100 kilometer (Including some additional sources outside this area) • Toured area around Class I Area • Extensive Oil and Gas Development • Extensive Dirt Road Network • Sand & Gravel Operation on Boundary • Toured Monitoring Site and Class I Area

9. Pilot Study: Current Status • Currently developing the Pilot SIP for visibility impairment from dust • Working with WRAP tools developed by the DEJF • Working with other tools developed by the WRAP for SIP development • Final product scheduled for completion at the end of September 2006.

10. Pilot Study: Current Status • Contractors currently developing supplemental analysis for the Dust Definition, including a local emission inventory of dust sources. • Cost for analysis - $22,000 • Back trajectory analysis has been completed and is available on WRAP’s web site. • Cost for analysis - $20,000

11. Pilot Study: Conclusions So Far • The usefulness of the research projects outside of WRAP tools developed • The DRI study, Identification of Source Areas Affecting Dust Concentrations at the Salt Creek and White Mountain Wilderness Areas in New Mexico, has been useful in determining what areas in New Mexico, as well as in other states and countries, that could be potential contributors.

12. Pilot Study: Conclusions So Far • The usefulness of the research projects outside of WRAP tools developed • The ENVIRON study, Application of the WRAP's Draft Definition and Categorization of Dust to the Salt Creek I Area, A Case Study, has not been completed, but will provide needed information on determining the percentage of anthropogenic versus natural sources, as well as more localized emission inventory data.

13. Pilot Study: Conclusions So Far • The information is there for the SIP development, but it is sometimes difficult to find • WRAP working on creating a resource list for state’s to use • TSS will be very helpful when completed • More specific planning information for other Regional Planning Organizations must be gathered independently

14. Pilot Study: Final Product • A template/protocol that states can use in developing the dust portions of their Regional Haze SIP’s • An evaluation of the WRAP tools currently available for use in the SIP development process • An evaluation of the supplemental analysis performed for the Salt Creek Wilderness Area • A list of additional resources needed
