Specifically, the order requires Evraz to take numerous actions, including:

  • Design, facilitate and install additional baghouse capacity and capture equipment no later than August 2013.
  • Install state-of the-art control technology and to capture emissions from the electric arc furnace, stir station and ladle reheat operations and direct emissions to a baghouse
  • Move the slag cooling operations currently conducted outside to inside the melt shop within six months of the effective date of the order.
