METHODS FOR ASSESSING IMPACTS

Air Quality

  • Negligible – an action that could change air quality, but the change would be so small that it would not be of any measurable or perceptible consequence.
  • Minor – an action that could change air quality, but the change would be slight and localized with few measurable consequences.
  • Moderate – an action that would result in readily apparent changes in air quality with measurable consequences.
  • Major – a substantial adverse or beneficial change in air quality would result.
