National Environmental Protection Act - NEPA

The National Environmental Policy Act requires all Federal agencies to assess and consider the environmental impacts of major Federal actions/decisions (e.g. projects, permit decisions, land management decisions). If no significant impacts to the environment or human health and welfare are anticipated as a result of a federal action, then an Environmental Assessment is completed and a Finding of No Significant Impact is used to document findings. When an agency concludes that a proposed Federal action has the potential for causing significant environmental impacts, it is required to prepare a detailed statement about those potential environmental impacts called an Environmental Impact Statement.
