Air Pollution Episode definition

Air Pollution Episode means a period when a forecast, alert, warning, or emergency air pollution state is declared, as stated in Chapter 173-435 WAC.
Air Pollution Episode means a combination of forecast or actual meteorological conditions and emissions of air contaminants which may or do present an imminent and substantial endangerment to the health of persons, during which the chief meteorological factors are the absence of winds that disperse air contaminants horizontally and a stable atmospheric layer which tends to inhibit vertical mixing through relatively deep layers.
Air Pollution Episode means a period of time during which high air contaminant concentrations are or may be brought about by meteorological parameters which are conducive to the poor dispersion of air contaminants. "High concentrations" means those concentrations which may result in significant harm to human health or welfare. An Air Pollution Episode is defined to exist only when either a County-wide or Localized Air Pollution Watch is in effect.

This occurs when there is a high pressure air mass over an area, a low wind speed and there is a temperature inversion. Other factors such as humidity may also affect the episode conditions.
Air Pollution Episode. Means a period when a forecast, alert, warning, or emergency air pollution stage is declared as described in RCW 70.94.715.
