Air Quality Action Day Forecast on July 23 for Four Pennsylvania Regions

HARRISBURG, Pa., July 22, 2011 /PRNewswire-USNewswire/ -- The Department of Environmental Protection and its regional air quality partnerships have forecast an air quality action day for Saturday, July 23, in the Liberty-Clairton, Philadelphia, Susquehanna Valley and Lehigh Valley regions.

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 air quality forecast predicts Saturday to be code ORANGE for ozone and particulate matter in all four regions. The Liberty-Clairton region is the municipalities of Clairton, Glassport, Liberty, Lincoln and Port Vue, all in southeastern Allegheny County. The Philadelphia region is Bucks, Chester, Delaware, Montgomery and Philadelphia counties. The Susquehanna Valley region is Cumberland, Dauphin, Lancaster, Lebanon and York counties. The Lehigh Valley region is Berks, Lehigh and Northampton counties.

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.

Ground-level ozone, a key component of smog, forms during warm weather when pollution from vehicles, industry, households and power plants "bakes" in the hot sun, making it hard for some people to breathe.

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

• Riding the bus or carpooling to work;
• Washing dishes and clothes only with full loads; and
• Saving energy by turning off unused lights in your home.

These forecasts are provided in conjunction with the Air Quality Partnership of the Delaware Valley, the Southwest Pennsylvania Air Quality Partnership, the Lehigh Valley/Berks Air Quality Partnership and the Susquehanna Valley Air Quality Partnership.
