Technical Coordinator Report

This report summarizes the outcomes of the Fall Technical Conference focused on dust research and the RA BART Backstop Trading Program. Key discussions included the refinement of SIP templates and technical support documents, as well as applied research reconciling dust transport modeling differences. The Gillette box model was found unreliable, while the ISC model demonstrated reasonable accuracy. Collaboration with WRAP and DOD was emphasized, alongside updates from working groups comprised of states, tribes, and FLMs to develop actionable solutions and regulatory frameworks for addressing air quality issues.
