During periods of poor air quality, young children, elderly people, and those with respiratory problems are encouraged to limit outdoor activities.
According to a forecast from the Pennsylvania Department of Environmental Protection, air pollution levels at the Liberty monitor are expected to stay in the moderate range for the rest of the day.
The Liberty monitor is about two miles away from U.S. Steel’s Clairton Coke Works, which has long been a major source of air pollution. It has some of the highest recorded fine particulate pollution readings in the region.
