1. RTOWG Update to TSC/WG, 2/24/21 Weekly coordination calls with Ramboll Discussion with EPA OAQPS leads on Regional Haze and modeling on WESTAR-WRAP glide slope end-point adjustments 2/16 Final draft of procedures document with options for visibility projections and glide slope end- point adjustments Upcoming meetings RTOWG meeting on March 2nd at 130 pm MST to cover methodology and examples for: a) 3 projections options for selecting a 2028 RPG, b) End-of-Glidepath Adjustment options, and c) Dynamic Modeling Evaluation and Modeling Glidepath March 9that 200 pm MST - Results meeting to review 2028 projections and end-of-glidepath adjustment display tools and options on TSS End of March Results meeting for TSS displays of Future Fire Scenarios, Dynamic Modeling Evaluation, and Low-Level Source Apportionment

2. Overview of Modeling Status and Schedule Left to complete with TSS delivery/display: 2002-RepBase2-2028OTBa2 Dynamic Evaluation and Modeling Glidepath of U.S. Anthropogenic reductions Future Fire Scenarios 1 (climate change-forced wildfire activity) and 2 (implementation of FLM scenario of wildland Rx fire activity) Left to complete both modeling and TSS delivery/display: Low-Level 2028OTBa2 Source Apportionment (state by source sector for WESTAR-WRAP region) Left to complete for TSS tools and results: cleanup efforts through April

3. WRAP Glidepath Adjustments At Cabinet Mountain WA and Sawtooth WA, adjustment for Wildland Prescribed fire adds to International contributions.
