Three takeaways from this story:
- A 2018 fire at the Clairton Coke Works revealed severe long-term maintenance problems, according to experts in a lawsuit.
- The risk of future breakdowns leaves Mon Valley residents vulnerable to high levels of pollution.
- The Allegheny County Health Department staff has lost trust in U.S. Steel and is asking the court to appoint an outside monitor to oversee a systemic fix to the problems.
David and Cindy Meckel arrived home in Glassport after a holiday vacation on Jan. 2, 2019. The air in the Mon Valley frequently has a rotten smell, they said, but when they returned home, the stench of “cat urine” was unbearable. The soot they wash off their home’s exterior a couple times a year required more than a full day of scrubbing. Some plants in their yard started to die.
They soon learned that a fire at the nearby Clairton Coke Works on Christmas Eve had knocked pollution control equipment offline. What they didn’t know — and what only became apparent more than a month later to regulators — was how serious the problem was. Thousands of tons of additional pollution were being released and burned at the Irvin Works, a facility within view of their home.
To environmentalists, the situation was like traveling back in time to the 1940s before the Clean Air Act: The company was burning coke oven gas without removing any of the potential harmful pollution for more than three months.
In the days following their return from vacation, David Meckel visited a doctor at Allegheny General Hospital with concerns about his breathing; he was prescribed an inhaler for the first time in his life. His wife, who was diagnosed with asthma in 2018, said she had to start using her inhaler six to seven times daily and woke up wheezing at night.
They weren’t the only ones with breathing problems. During the time that the company’s pollution controls were down, the number of visits to doctor’s offices and emergency rooms for asthma nearly doubled in the ZIP code that includes Clairton, according to a study published earlier this year. Asthma patients closer to the coke works had worse symptoms during that time period, according to a separate University of Pittsburgh study.
And according to an ongoing lawsuit, there is an imminent risk of this kind of massive pollution release recurring. The 2018 fire happened because of a series of preventable problems that plaintiffs argue revealed just how poorly maintained the coke works has been; this leaves residents vulnerable to additional breakdowns that could expose them to harmful levels of pollution in the future. The Allegheny County Health Department, which joined the lawsuit, doesn’t have the authority to clamp down on maintenance neglect and has lost trust in the company to do it on its own, according to staff testimony in the lawsuit.
U.S. Steel argues in the case that it’s spent millions of dollars improving upon its already industry-leading safety program, that it doesn’t cut corners on maintenance and that there is little evidence to support harm to residents from the fire based on the official air quality monitors nearby.
Why pollution shifted to and increased at the Irvin Works
The Irvin Works is normally considered the cleanest of U.S. Steel’s three Mon Valley facilities. But after the 2018 fire at the Clairton Coke Works, the company said it burned uncleaned coke oven gas at the Irvin facility about 5 miles away because it was the best option. A tall pipe on a hill called “the peachtree flare” would spread the pollution higher and farther, so the impact wouldn’t be as intense on nearby residents, even as it impacted a wider area.
But spewing pollution from the flare also made it difficult to measure how dirty the emissions leaving Irvin were. The coke ovens at the Clairton plant have devices that can measure the pollution, but not the flare.
The Edgar Thomson plant in Braddock and the Clairton Coke Works have sophisticated air pollution monitors in nearby communities to measure the everyday pollution based on the prevailing winds. But there wasn’t a similar monitor downwind of the Irvin Works. So thousands of tons of additional pollution weren’t being precisely recorded anywhere.
U.S. Steel’s air quality permits are structured so the company would be fined once per day, at a cost of about $100,000, for violating its pollution permit at the Irvin flare. But the Edgar Thomson and Clairton plants are more intensely regulated and could’ve potentially incurred millions of dollars in additional fines per day.
When the company brought its pollution controls back online in April, asthma patients in the area reported that their breathing improved and emergency room visits dropped.
A predictable fire
According to plaintiffs’ documents in the recent court case against U.S. Steel, the “decrepit” conditions at the Clairton Coke Works are so grave and so persistent that there is an ever-present risk of additional fires and breakdowns.
The case, brought by PennEnvironment and the Clean Air Council in 2019, seeks to make the company undertake a long list of deferred maintenance that plaintiffs say is needed to prevent future fires, at a likely cost tens of millions of dollars. The lawsuit asks the court to appoint an expert to oversee the additional maintenance and a potential redesign of the facility that would prevent breakdowns. They are also seeking torecoup the tens of millions of dollars in profits they believe the company earned by delaying work that could’ve prevented the fire or limited the pollution.
The parties have exchanged internal documents and interviewed each other’s witnesses but a trial date has not yet been set. The case has generated more than two million pages of documents. Not all of the documents are public, but PublicSource looked over thousands of available pages, including the key complaints and responses, reports by expert witnesses, internal company documents and the depositions of expert witnesses, including U.S. Steel staff, health department staff and local residents who say they were harmed by the fire.
U.S. Steel declined an interview request about the lawsuit. “An interview is not appropriate because of pending litigation, and for the same reason we are unable to answer many of the questions,” wrote Amanda Malkowski, a spokesperson for U.S. Steel.
U.S. Steel announced earlier this year that it would not invest $1.5 billion in upgrades at its Mon Valley plants, some of which would’ve decreased pollution levels in Clairton. But Malkowski said the company’s plan to shut down three of its dirtiest batteries in Clairton by 2023 “will possibly” result in an even larger “environmental improvement” than its initial investment plan.
According to internal company documents uncovered by the plaintiffs, the 2018 Christmas Eve fire was not an unexpected or isolated incident but the result of years of cutbacks on maintenance and repairs in a plant that is designed with little margin for error. The fire itself was a kind of tragedy of errors, with multiple equipment failures cascading into a football field-sized fireball that lasted for two hours and put the nearby communities at risk for months afterward.
The points of failure were numerous: an undetected roof leak and corroding pipe connector; a failed oil leak warning system; a metal shaft with a crack 80% of the way through; a malfunctioning gas backflow valve. After the fire was over, the company spent $17.5 million to correct problems, including replacing cooling pipes that had become “Coke can thin.”
The fire was caused and made worse by the failure of numerous backup systems, many of which didn’t get regular inspections or maintenance, according to the analysis of Ranajit Sahu, an expert hired by the plaintiffs with decades of experience researching coal and power plants. More than two years after the fire, U.S. Steel still had a number of vulnerabilities it hasn’t addressed, according to Sahu’s reports.
“U.S. Steel is, in effect, rolling the dice and hoping they will be lucky enough to avoid disasters before finally getting around to taking needed actions,” he wrote.
In a statement to PublicSource, U.S. Steel said it has made major investments in the Mon Valley in the past three years and that it has an “industry-leading” maintenance program.
More fires, few inspections
According to court documents, the last time the Clairton Coke Works was fully inspected before the fire was 2003. The inspection identified problems in some of the very component types that led to the 2018 fire.
In 2009, there was an explosion at the plant in the very same location: The 2009 fire resulted in the death of a U.S. Steel employee. Although the employee’s family sued the company, U.S. Steel was never sanctioned by any government regulatory agency for the fire.
“They had been through a trial run of this, in 2009 … It’s not like they didn’t have time to prepare,” said Zachary Barber, a clean air advocate for PennEnviroment. “What were they doing in the decade between those two fires?”
The lawsuit also identified two other plant shutdowns on Jan. 6, 2014, and Nov. 23, 2016, that impacted the plant’s pollution controls and hadn’t previously been reported.
U.S. Steel argues in court documents that the Christmas Eve fire led to only a handful of exceedances of national air quality standards. Its expert witness casts doubt on whether the fire could have caused symptoms described by nearby residents. The company argues that requiring an outside monitor to oversee a company’s internal maintenance is impractical and unwarranted by the facts of the case.
In court testimony, the Allegheny County Health Department [ACHD] laid out why the agency can’t prevent future large-scale pollution violations in the Mon Valley. The department relies on companies to make good faith efforts, staff said. But they say they’ve increasingly found U.S. Steel resistant to oversight. The company’s response to the fire was further evidence to health department staff that the company was putting its own profits above the well-being of residents.
A spokesperson for the health department said they could not discuss ongoing legal matters. But depositions of key department staff paint a damning picture of how county regulators viewed U.S. Steel’s compliance efforts before and after the fire.
Can U.S. Steel be trusted?
Jim Kelly, who was director of the department’s environmental health division but left in May, testified that the Clairton Coke Works is “one of the most decrepit facilities I’ve ever seen in my nearly 30 years of work.”
He also said U.S. Steel has a history of misleading the health department about its true intentions. The company had misrepresented itself in negotiations, Kelly said, offering to undertake changes it said would improve its environmental record but which, Kelly later learned, had really been done to save money. He also said health department inspectors believe they are not seeing the full picture of what goes on at U.S. Steel’s plants. Kelly said he believes U.S. Steel uses more staff to run equipment during inspections, compared to nearby equipment that isn’t being inspected.
U.S. Steel said in an email response that it would be impractical for the company to change staffing levels based on inspections: “ACHD employees and/or contractors (depending on day and time of day) are at our facility every single day, so it would be impossible to adjust operations for these visits.”
U.S. Steel’s initial report to the health department that the fire would result in “light to moderate” pollution and that its pollution controls would be back on within hours was “terribly misleading,” Kelly said. It wasn’t until the health department asked for and received more detailed emissions information at the beginning of February, about six weeks after the fire, that the health department realized just how much pollution had been pouring into the Mon Valley.
Not only was U.S. Steel withholding this important information, he said the efforts they made to limit their pollution after the fire were not done “in the best faith.” In Kelly’s view, the company had reduced its pollution much more quickly in the past when it was for economic reasons.
“A lot of facilities are proactive: A problem is happening or a problem happened. They deal with it. They report it. They move on,” Kelly said. “We have to draw the information out of U.S. Steel.”
Even before the fire, the Allegheny County Health Department had begun escalating its efforts to try to bring pollution in Clairton under control.
Air pollution in Allegheny County has been improving steadily since 2000. But in 2013, the average yearly amount of fine particulate matter stopped decreasing near the Clairton Coke Works and even got worse over the next four years.
The pollution problems in the Mon Valley coincided with a U.S. Steel effort to cut costs, dubbed by the company: “The Carnegie Way.” Company staff levels were cut by a quarter, according to a report in the Wall Street Journal.
A presentation in Clairton by a consultant for the company, McKinsey and Company, showed that, by 2018, the Mon Valley facilities had reduced their full-time maintenance staff to under 700 employees, four years sooner than was originally forecasted. That was nearly 200 fewer employees than two years before.
Mon Valley workers had concerns. “Everything is being run to failure,” said one worker, according to a slide from the McKinsey presentation. “The guys here want to do a good job, but the bosses want them to hurry up to make more coke,” said another worker. “We have lots of ’temporary repairs’ that become permanent … we are not good at coming back and doing the repair right,” said a third worker.
Malkowski said the company has hired 300 additional staff at Clairton since 2018 but couldn’t specify how many of them were involved in maintenance. “We consistently hire at the Clairton Plant and consider our employees our greatest asset,” she wrote.
The health department staff had enough
Amid the company’s cost-cutting campaign, the health department increased the stringency of its permits with U.S. Steel and increased the size of penalties for all companies with violations. After four years of rising or stagnant pollution levels, the amount of fine particulate pollution in the Mon Valley decreased significantly in 2018. But then the fire happened, and particulate pollution increased again in 2019.
The health department was widely criticized for not informing residents about the fire for more than two weeks. In depositions for the court case, health department staff described a regulatory process where they were relying on U.S. Steel to be forthcoming.
“Given what we finally learned in terms of the volume of emissions, it does raise questions about what they may have known that they did not tell us,” Karen Hacker, the director of the health department until July 2019, said in a November 2020 deposition. “It was much higher than we could have imagined, and they had not shared that information with us.”
When an electrical fire knocked out the company’s pollution controls a second time in June 2019, Hacker said it was more evidence of the company’s poor record.
Jayme Graham, the co-director of the air quality division, criticized the company for not reducing its production to limit the impacts of the pollution “more quickly and more stringently” but said “they chose not to.”
Kelly said the company claimed it would take 90 days to safely put its coke oven plant batteries on “hot idle” — essentially turning the ovens off but still keeping heat in them to protect them. Batteries that were “hot idling” would not be producing any coke or pollution. The health department later found historical examples of U.S. Steel “hot idling” in only 35 days.
The health department rarely gets a chance to proactively regulate Clairton’s pollution. But that is changing. Earlier this year, the health department passed a new rule requiring companies to take action to reduce their pollution in the Mon Valley when the weather would trap it in place (called an inversion).
The lawsuit is another step in this direction. Air quality activists have criticized the health department for not doing enough to protect residents’ health. And the department’s response has typically been that it is doing everything it can under the law. In the lawsuit, the department says its current powers under the law are not enough to protect the public from pollution events like the fire.
Now, it’s asking the court for help.
