• Annual Standard Data Flagging– Apply To Any And All Data Impacted By Natural Events
• Timeframe For Documentation Submittal– Documentation Should Be Collected Immediately– Submitted To EPA Within 180 Days Following Quarter When
States Make A Finding Of A Violation
• Bright Line For What Constitutes A “High Wind”– Maintain Current Distinction Between “Natural” And “Exceptional”
