National Environmental Policy Act

The National Environmental Policy Act (NEPA) was established to foster and promote the general welfare, to create and maintain conditions under which man and nature can exist in productive harmony, and fulfill the social, economic, and other requirements of present and future generations of Americans. While NEPA affirmed each person's responsibility to preserve and enhance the environment, it emphasized the federal government's leading role in that effort.

NEPA requires all federal agencies to consider the environmental impacts of their proposed actions and reasonable alternatives to those actions. The NEPA process is intended to help public officials make decisions that are based on understanding environmental consequences and take actions that protect, restore, and enhance the environment.

The NEPA process consists of an evaluation of the environmental effects of a federal undertaking including its alternatives. The NEPA process enables us to make informed decisions about the consequences of our projects, to inform the public about our findings, and to take actions that will protect the environment.

MDA's NEPA program is managed by the Mission Support Directorate. The program ensures MDA is proactive in meeting its Federal stewardship responsibilities while ensuring mission success and lowering environmental liability.
