DEP Issues a Code Orange Air Quality Action Day Forecast for the Southeastern Pennsylvania Region for August 6, 2018

DEP Issues a Code Orange Air Quality Action Day Forecast

HARRISBURG, PA — The Pennsylvania Department of Environmental Protection (DEP) and its regional air quality partnerships have forecast a Code Orange Air Quality Action Day for ozone on Monday, August 6, 2018, for the 5-county Philadelphia area (encompassing the counties of Bucks, Chester, Delaware, Montgomery and Philadelphia).

Stagnant conditions early in the day with a light southwesterly wind in the afternoon under mostly sunny skies will lead ozone concentrations to climb into the Code Orange range.

Increasing chances for showers and thunderstorms Tuesday afternoon are expected to limit ozone concentrations to the moderate range. Therefore, the Code Orange Air Quality Action Day is currently only expected for Monday.

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 Air Quality Partnerships for the Delaware Valley.
