  • Uncertainty related to the engineering scope and cost of mitigation required to meet applicable water standards, and responsibility for the financial liability.
Mitigation Strategies
  • Completing a thorough environmental review and utilizing existing infrastructure (Erie Plant).
  • Developing key mitigation plans and incorporating them into the SDEIS to demonstrate that the NorthMet project meets all state and federal standards.
