Notice

The TSS website is operational for Round 2 Regional Haze analysis results for the WESTAR-WRAP region. Minor changes and updates will need to continue to be made to tool formats and documentation links as needed. Those changes will be noted on the TSS so users can easily identify them.

Updates
