Integrated Iron and Steel Manufacturing: National Emission Standards for Hazardous Air Pollutants

Rule Summary

This rule promulgates national emission standards for hazardous air pollutants (NESHAP) for integrated iron and steel manufacturing facilities. The final standards establish emission limitations for hazardous air pollutants (HAP) emitted from new and existing sinter plants, blast furnaces, and basic oxygen process furnace (BOPF) shops. The final standards will implement section 112(d) of the Clean Air Act (CAA) by requiring all major sources to meet HAP emission standards reflecting application of the maximum achievable control technology (MACT).

The HAP emitted by integrated iron and steel manufacturing facilities include metals (primarily manganese and lead with small quantities of other metals) and trace amounts of organic HAP (such as polycyclic organic matter, benzene, and carbon disulfide). Exposure to these substances has been demonstrated to cause adverse health effects, including chronic and acute disorders of the blood, heart, kidneys, reproductive system, and central nervous system.
