“Carnegie Mellon University’s CREATE Lab is expanding the focus of its Breathe Cam network of air pollution-capturing cameras to include three U.S. Steel Corp. facilities in the Mon Valley: the Edgar Thomson Plant in Braddock, the Irvin Plant in West Mifflin and its coke works in Clairton.
“The cameras, activated Tuesday, will provide 24-hour-a-day monitoring of visible air pollution, and give residents and government agencies an additional way to document smoke, fugitive emissions and other visible air pollution. . . .
“Although the health department already monitors smokestack emissions at all three plants, Mr. Sargent said the cameras will make it possible to see ‘fugitive emissions’ — air pollution that escapes the coking and steel-making processes episodically and through other, different pathways.
“The cameras will also show the color of the emissions, which can give observers clues to their chemical composition, he said. The cameras are located from half a mile to three miles from each plant.”
