Training and Testing
Supplemental Environmental Impact Statement/Overseas Environmental Impact Statement
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) announces its intent to prepare a supplement to the 2015 Northwest Training and Testing Final EIS/OEIS to assess the potential environmental effects associated with military readiness activities, including training and research, development, testing, and evaluation (hereafter referred to as “training and testing”) activities conducted within the EIS/OEIS Study Area (hereafter referred to as the “Study Area”). As part of this process, the Navy will seek the issuance of federal regulatory permits and authorizations under the Marine Mammal Protection Act and Endangered Species Act to support future military readiness activities within the Study Area beyond 2020.
The Supplemental EIS/OEIS will include an analysis of training and testing activities projected to occur after 2020 using the best available scientific information currently available, including an updated acoustic effects model and updated marine mammal density data. Proposed training and testing activities are generally consistent with those analyzed in the previous EIS/OEIS and approved in the 2016 Record of Decision, and are representative of activities the Navy has been conducting in the Study Area for decades.
