Lehigh will be required to reduce their air pollution by 4,555 tons of nitrogen oxide (NOx) and 989 tons of sulfur dioxide (SO2) each year according to the new settlement with the EPA. The goal is to reduce air pollution in compliance with state and federal laws.

The company will have to pay $1.3 million for its Clean Air Act violations, and it will invest in cleaner air technology such as new truck engines and pollution controls. The new settlement and controls will greatly improve the conditions of local communities that suffer the pollution from local plants.
