Why is the Navy Preparing an EIS/OEIS?

The U.S. Navy has prepared this Final Environmental Impact Statement/Overseas Environmental Impact Statement (EIS/OEIS) to assess the potential effects on the environment from current and ongoing Navy activities as well as from potential adjustments in training and testing activities as the Navy plans for the future. This EIS/OEIS will assist the Navy in consolidating and renewing regulatory permits and authorizations under various environmental laws and regulations. 

The EIS/OEIS also gives the Navy the opportunity to review its procedures to ensure that the benefits of recent scientific and technological advances are applied toward minimizing environmental effects.

The National Environmental Policy Act (NEPA) of 1969 requires federal agencies to examine the direct, indirect and cumulative, or additive, environmental effects of their activities. An EIS is a detailed public document that provides an assessment of the potential effects a federal action may have on the human, natural or cultural environment.

An OEIS is prepared to comply with U.S. Executive Order 12114, Environmental Effects Abroad of Major Federal Actions, of 1979. The Executive Order requires federal agencies to consider the potential effects of their actions on the environment outside U.S. territorial waters. U.S. territorial waters extend 12 nautical miles from shore.
