Understanding the Process Timeline


The California Environmental Quality Act (CEQA) requires the Nevada County to produce an independently written Environmental Impact Report (EIR) to inform the decision-making process about whether or not to re-open the Idaho-Maryland Mine. The approval process for the mine is regulated by CEQA, making the whole effort a marathon, not a sprint.

Here are the highlights:

  1. Notice of Preparation - July 2020 - Complete

  2. Draft Environmental Impact Report (DEIR) Comments & Public Hearing - Apr 2022 - Complete

  3. Bonus Step - Economic Impact Report Released by County - Dec 2022 - Complete (This report was ordered separately by the County and is not a CEQA requirement)

  4. Final Environmental Impact Report (FEIR) Comments & Public Hearing - May 2023 - Complete

  5. Planning Commission Votes - May 2023 - Complete (It was a unanimous "no" vote)

  6. Board of Supervisors Votes - Estimated early fall 2023
