Environmental Impact Statement:
How does the EIS fit into the NEPA review process?
EPA prepares an Environmental Impact Statement (EIS) when it determines a proposed project is likely to have significant environmental impacts. EPA prepares an EIS when:
- An Environmental Assessment (EA) has been initiated or completed, and the findings demonstrate that significant environmental impacts may occur from the proposed action.
- EPA determines that a proposed project may have a potentially significant impact on the human environment and that mitigation of the impacts may not be possible.
