DEP Declares Code Orange Air Quality Action Day In All 5 Air Quality Partnership Areas For Monday, June 18

The Department of Environmental Protection and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone in all 5 Air Quality Partnership Areas for Monday, June 18.  Those areas include--

-- Liberty-Clairton: Liberty, Clairton, Port Vue, Lincoln, Glassport, Allegheny County;

-- Southwest PA: Allegheny, Armstrong, Beaver, Butler, Fayette, Washington, Westmoreland counties;

-- Southcentral PA:  Cumberland, Dauphin, Lancaster, Lebanon, and York counties;

-- Lehigh Valley: Berks, Lehigh Northampton counties; and

-- Southeast PA: Bucks Chester, Delaware, Montgomery and Philadelphia counties.

A strong ridge of high pressure, a mostly sunny sky, temperatures in the lower to middle 90s Fahrenheit, and west to southwesterly transport will be highly favorable for ozone formation on Monday. This will result in code ORANGE conditions to southeast Pennsylvania Sunday into Monday. An approaching cold front will bring a better chance for afternoon and evening thunderstorms Tuesday, reducing the risk for elevated ozone.

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.

The U.S. Environmental Protection Agency’s standardized air quality index uses colors to report daily air quality. Green signifies good; yellow means moderate; orange represents unhealthy pollution levels for sensitive people; and red warns of unhealthy pollution levels for all.

To help keep the air healthy, residents and business are encouraged to voluntarily restrict certain pollution-producing activities by:

-- Refueling cars and trucks after dusk;

-- Setting air conditioner thermostats to a higher temperature;

-- Carpooling or using public transportation; and

-- Combining errands to reduce trips.

These forecasts are provided in conjunction with the Delaware Valley Air Quality Partnership, Susquehanna Valley Air Quality Partnership and the Lehigh Valley-Berks Air Quality Partnership.
