The state Department of Environmental Protection said Wednesday will be a Code Orange Air Quality Action Day in the Liberty-Clairton area, where elevated concentrations of fine particles in the atmosphere will be hazardous for young children, the elderly and people with such respiratory problems as asthma, emphysema and bronchitis.
The DEP recommends that those people limit outdoor activities.
Tuesday morning, communities surrounding the U.S. Steel Corp. Clairton Coke Works experienced particulate levels that led to Code Red, which is a level unhealthy for everyone. Those conditions emerged after midnight and persisted until around noon.
The U.S. Environmental Protection Agency uses an air-quality index of colors to report daily air quality. Green signifies good air with yellow representing moderate air quality. Orange represents unhealthy pollution levels for sensitive people, while red warns of unhealthy 0pollutioion levels for everyone.
The Liberty-Clairton area also includes Glassport, Lincoln and Port Vue.
