"President Trump is exempting coal used in steelmaking from Biden-era Clean Air Act regulations for two years.
Trump on Friday issued a proclamation exempting facilities known as coke ovens from a rule limiting their releases of pollutants, such as mercury, formaldehyde, soot and dioxins.
The rule that the facilities were exempted from also would have required them to monitor for a separate cancer-causing chemical called benzene at the fence line of their facility."
