What Is NEPA?
NEPA is the acronym for the National Environmental Policy Act. This act, passed in 1969, laid the foundation for environmental protection in the United States by setting policy goals for the federal government. Two major requirements of the act are that agencies analyze the environmental impacts of federal actions and engage the public in the decision-making process.
