Welcome to the U.S. Navy's website for the Northwest Training and Testing Supplemental Environmental Impact Statement/Overseas Environmental Impact Statement (EIS/OEIS).

The Department of the Navy (Navy) has prepared a draft supplement to the 2015 Northwest Training and Testing Final EIS/OEIS to reassess the potential environmental impacts associated with conducting proposed ongoing and future military readiness activities within the Northwest Training and Testing Study Area, referred to as the "Study Area." Military readiness activities include training and research, development, testing, and evaluation activities, referred to as "training and testing."

The supplement to the 2015 NWTT Final EIS/OEIS supports proposed ongoing and future activities conducted at sea and in associated airspace within the Study Area beyond 2020. Proposed activities are similar to those conducted in the Study Area for decades and analyzed in the 2015 document.

In the Draft Supplemental EIS/OEIS, the Navy evaluated new, relevant information, such as more recent marine species density data and new scientific information, and updated the environmental analyses as appropriate. The Navy prepared the Draft Supplemental EIS/OEIS to support the issuance of federal regulatory permits and authorizations under the Marine Mammal Protection Act and the Endangered Species Act.
