The Pennsylvania Department of Environmental Protection (DEP) has issued a Code Orange Air Quality Action Day for ozone for Sunday, August 9, 2020, for the counties of Allegheny, Armstrong, Beaver, Butler, Fayette, Washington, and Westmoreland in southwestern Pennsylvania.
Sunday's forecast of mostly sunny skies, light and variable winds, and temperatures rising close to 90 degrees will lead to favorable conditions for ozone development in the late morning and early afternoon Sunday with concentrations increasing to the Code Orange level.
The U.S. Environmental Protection Agency's (EPA) Air Quality Index (AQI) provides standardized color codes for forecasting and reporting daily air quality. Green signifies good air quality; yellow means moderate air quality; orange represents unhealthy pollution levels for sensitive groups of people; and red warns of unhealthy pollution levels for all.
An Air Quality Action Day is issued when the AQI is forecasted to be code orange or higher. On air quality action days, young children, the elderly, and those with respiratory problems, such as asthma, emphysema, and bronchitis, are especially vulnerable to the effects of air pollution and should limit outdoor activities.
Residents and businesses within the Air Quality Action Day area are strongly encouraged to voluntarily help reduce air pollution by:
