PennEnvironment and Clean Air Council want a federal judge to find that U.S. Steel violated the Clean Air Act thousands of times after the 2018 Christmas Eve fire at the Clairton Coke Works.
The Pittsburgh Post-Gazette spoke with Allegheny County councilperson Bethany Hallam about how she defines "progressive," the Clairton Coke Work's environmental impact and the Democratic presidential primary.
Last Christmas Eve, a sprinkler pipe at a United States Steel Corp. plant south of Pittsburgh fell from the ceiling in a building at the 120-year-old complex. Within minutes, an area the size of a football field was engulfed in flame.
For the third time in less than a year, the Allegheny County Health Department has fined U.S. Steel for excessive air pollution emissions at its Clairton Coke Works in the Mon Valley.

The Allegheny County Health Department has ordered U.S. Steel Corp. to end repeated and ongoing violations of federal sulfur dioxide standards at its three Mon Valley Works plants following a Dec. 24 fire that knocked out pollution controls at the Clairton Coke Works.
A new air quality monitor has been installed in West Mifflin, the Allegheny County Health Department announced Monday.
A sulfur dioxide level in excess of the federal health standard was recorded Monday evening in Braddock, near U.S. Steel's Edgar Thomson Steel Mill, according to the Allegheny County Health Department.
U.S. Steel expects to pay at least $40 million to repair damage caused by a mechanical fire at its coke plant in Clairton that triggered an air quality alert from Allegheny County health officials, the Pittsburgh steelmaker told investors on Wednesday.
PITTSBURGH—On January 9, residents of 22 Pittsburgh-area neighborhoods were advised by their county health department to minimize outdoor activity because of high levels of sulfur dioxide pollution in the air.
The pollution was caused by a fire 16 days earlier on Christmas Eve at U.S. Steel Corp.'s Clairton Coke Works Plant that damaged equipment. The maximum legal safety threshold for sulfur dioxide pollution was exceeded in the region six times before the public was informed or a health advisory was issued.
According to the Allegheny County Health Department's data, the air monitor closest to the plant detected sulfur dioxide at 145 parts per billion (ppb) on December 28—nearly double the maximum hourly safety threshold of 75 ppb.
When the notice was posted on the Health Department's Facebook page, a number of affected residents expressed anger that they weren't warned earlier (the Health Department has since publicly defended its approach), and concern for their health.
"A little late warning the public," one user wrote, "[since] there's a lot of sickness in these towns for weeks now." She added that she'd gone to her primary care physician due to headaches and breathing issues prior to the warning being issued, writing, "Very angry over the delay of this!"
Another user stated that her mother, who lives in the impacted region, had to be admitted to the hospital due to exacerbation of her COPD/emphysema, writing, "That info should have been reported earlier," while another wondered, "How many of our children were exposed to this during the holidays when they were off of school and outside playing?"
Respiratory irritation from sulfur dioxide exposure induces symptoms such as sneezing, sore throat, wheezing, shortness of breath, chest tightness, and a feeling of suffocation, according to the U.S. Centers for Disease Control and Prevention. At the levels caused by the Clairton fire, those most at risk are people with chronic respiratory illnesses like asthma and COPD, those with heart disease, children, and the elderly.
According to a spokesperson for the American Lung Association, even people with mild asthma may experience symptoms like wheezing, shortness of breath and chest tightening as a result of exposure to sulfur dioxide.
"We know from human exposure studies that even people with mild or moderate asthma can experience a significant drop in lung function as a result of relatively short periods of exposure," Kevin Stewart, American Lung Association Director of Environmental Health, Advocacy and Public Policy, told EHN.
"People with asthma are more likely to experience problems when exercising outdoors, since breathing more of the air containing sulfur dioxide can more quickly lead to bad outcomes."
Stewart noted that respiratory infections and mortality in the general population have also been linked to sulfur dioxide exposure. As a result of these concerns, the American Lung Association recently urged the Environmental Protection Agency to lower the maximum exposure threshold for sulfur dioxide from 75 ppb to 50 ppb to be more protective of health.
Children with asthma—and Pittsburgh has many—are especially at risk.
Children breathe more quickly than adults, so they inhale more of whatever is in the air. They're also more likely to be active outdoors than adults.
"While kids are still developing, they have different biochemistry in their lungs since they're not yet fully matured," Stewart said. "We're also aware that with children being smaller, their airways are smaller, so even in healthy children, some inflammation of the airways can occur as a result of sulfur dioxide exposure."
When it comes to long-term effects, the primary concern with sulfur dioxide exposure is an overall decrease in lung function as a result of inflammation, especially in those with asthma or other chronic respiratory illness. Sulfur dioxide is not considered a carcinogen.
Stewart advised residents to follow health advisories that suggest limiting outdoor activity, keeping an eye on air quality data for the region as it becomes available, and being mindful of new symptoms.
Anyone with chronic lung or heart disease should have a plan in place with their physician(s), he said, in the event of an exacerbation or emergency caused by sulfur dioxide exposure.
"If you're experiencing irritation immediately upon breathing outdoor air, that's certainly a sign of exposure," he said. "Not every chemical odor means there's a potential health effect, but they can be an indicator that there are things in the air that are unhealthy to breathe, and this is probably a good time to exercise caution."

A Dec. 24 fire at U.S. Steel Corp.'s Clairton Coke Works, which significantly damaged its coke gas feed operations, produced high levels of air pollution and Wednesday led the Allegheny County Health Department to issue an air quality advisory for 22 Mon Valley communities.
