The Department of Environmental Protection and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone for Saturday, July 27 in Bucks, Chester, Delaware, Montgomery and Philadelphia counties.
On Saturday, mostly sunny skies, light recirculating winds, and high temperatures around 90 degrees Fahrenheit will act to produce elevated levels of ozone during the day. Since there will be no change in air mass Sunday into Monday, DEP will continue to monitor the situation over the weekend and issue further action days as needed.
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 DEP’s regional air quality partnerships, including the Air Quality Partnership for the Delaware Valley.
