EIS & EA
The Montana Department of Transportation (MDT) prepares an environmental study as required by the Montana Environmental Policy Act (MEPA) or the National Environmental Policy Act (NEPA) for actions taken by the MDT unless exempted by law. An action may include projects, permits, and studies where MDT expends funds or takes an action affecting the human environment. These environmental studies determine the affects of the action on the social, economic or natural environment and may result in the preparation of an Environmental Assessment or Environmental Impact Statement. Active and completed documents are listed below.
Any information obtained will not be used for commercial or advertising purposes. Public comments regarding a project, environmental study or public meeting become part of the public record and may be posted in MDT documents or made available on MDT's website. Contact information is retained in all public comments as a measure of accountability and to validate the submitted comment.
