Fact Sheet: Final Amendments to Air Toxics Standards …
• EPA issued the initial air toxics standards for Taconite Iron Ore Processing on October 30, 2003. The rule applies to major source facilities engaged in separating and concentrating iron ore from taconite (a low-grade iron ore) to produce taconite pellets. These taconite pellets are then used as feed in blast furnaces to produce steel.
