National Environmental Policy Act Guidance

The National Environmental Policy Act (NEPA) established a national environmental policy and goals for the protection, maintenance and enhancement of the environment. It requires agencies like MDOT to assess the environmental effects of their proposed actions prior to making decisions. Using the NEPA process, MDOT evaluates the environmental and related social and economic effects of their proposed actions.
