US Steel’s Clairton Coke Works in Pennsylvania has been fined over $1 million for ongoing violations of an air-quality agreement. Additionally, US Steel is required to submit a comprehensive assessment of its coke batteries to the health department within 60 day and implement remedies within 30 days of the department’s approval.
If pollution continues over two consecutive calendar quarters, the company’s two worst-performing coke batteries will be ordered to cease operation until the health department determines the plant is back in compliance with the agreement.
The health department and US Steel agreed on a plan in March 2016 to resolve air quality violations at the Clairton plant. According to the health department, the plant showed early progress, but recent data shows a downward trend in compliance of fine particulate matter.
