Designation Process • ARB adopts State standards to

and area designations• Designations indicate

healthfulness of air quality• Designations reviewed annually

Data to Use

• “Data for Record”Meet siting and QA proceduresCollected by ARB, Districts, othersReflect expected highest

concentrations• Time Period

Most recent 3 calendar yearsCurrent review: 2010-2012

Exceedance vs. Violation

• ExceedanceConcentration higher than standardQualifying exceedances are

excluded as Highly Irregular or Infrequent

Events• Violation

Exceedance not excluded as Highly Irregular or Infrequent Event

• Not all exceedances are violations
