National Environmental Policy Act (NEPA) Environmental Documents

Whenever BLM or anyone else proposes a project on public lands managed by BLM, the project must be analyzed to determine how it will affect the environment.

There are four possible levels of environmental analysis:

  • AD = Administration Determination - An administrator determines that the project is already covered by an earlier analysis.
  • CX = Categorical Exclusion - The project falls into one of several categories of minor, routine projects excluded from needing more analysis.
  • EA = Environmental Assessment - The project is analyzed to see how it may affect the environment, This leads to a Finding of No Significant Impact (FONSI) - or, if the EA shows a significant impact is likely, an EIS is done.
  • EIS = Environmental Impact Statement - A detailed study is done and a report is written stating what the environmental impacts would be, and how they can be avoided or mitigated.
