NOTES: Some demonstrations are still in development, not all packages received are complete; most flags (non-SO2) currently do not have documentation; not all flagged data are exceedances; often a single event has many flags (multiple measurements for a single averaging time, multiple sites, multiple monitors/site, multiple pollutants); Region 9 received >50 demonstration packages for events prior to Jan. 1, 2009, and took appropriate action on all complete demonstrations of regulatory significance (designations or redesignations).
Example: Arizona had 544 PM10 Exceedances (2009 to 2011), of which 367 were flagged (67%). Arizona submitted a complete demonstration for 30, and EPA concurred on 29 of those (as of Oct. 2012).
