Environmental Reviews

Environmental Documents are provided for by the National Environmental Policy Act (NEPA). NEPA is our basic national charter for protection of the environment. These documents provide environment information to public officials and citizens before decisions are made and before actions are taken.

NEPA documents provide full and fair discussion of significant environmental impacts. They inform decision makers and the public of the reasonable alternatives which would avoid or minimize adverse impacts or enhance the quality of the human environment. Documents are to be concise, clear and to the point, and should be supported by evidence that the agency has made the necessary environmental analyses. NEPA documents must concentrate on the issues that are truly significant to the action in question, rather than amassing needless detail.

The NEPA process is intended to help public officials make decisions that are based on understanding of environmental consequences, and take actions that protect, restore, and enhance the environment. Accurate scientific analysis, expert agency comments, and public scrutiny are essential to implementing NEPA.
