Federal laws and regulations (including NEPA, the National Environmental Policy Act of 1969) require the federal government to evaluate effects of its actions on the environment and to consider alternative courses of action. An EIS is the required document that describes the positive and negative impacts on the environment as a result of a proposed action, impacts of alternatives and ways to mitigate the impacts. The Council for Environmental Quality (CEQ) regulations stipulates the recommended format and content of Environmental Impact Statements.
