Coke Ovens: Pushing, Quenching and Battery Stacks: National Emission Standards for Hazardous Air Pollutants
On this page:
Rule Summary
The Environmental Protection Agency (EPA) finalized amendments to update and strengthen emission standards for hazardous air pollutants (HAP) such as benzene, mercury, lead and arsenic that are emitted by coke oven facilities.
Coke is used in blast furnaces in the conversion of iron ore to iron, which can be further refined to produce steel. Coke plants produce coke from coal, using coke oven batteries. A battery consists of a group of ovens connected by common walls.
The final amendments will fulfill EPA’s responsibility under the Clean Air Act to periodically review emission standards to reflect developments in pollution control technologies and techniques, and to establish standards for all types of HAP emitted by regulated facilities.
