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

The Department of the Navy (Navy) has prepared a final supplement to the 2015 Mariana Islands Training and Testing Final Environmental Impact Statement/Overseas Environmental Impact Statement (EIS/OEIS) to assess the potential environmental impacts associated with ongoing at-sea and Farallon de Medinilla (FDM) training and testing activities conducted within the Mariana Islands Training and Testing (MITT) EIS/OEIS Study Area (hereafter referred to as the “Study Area”). Proposed activities are generally consistent with previously analyzed activities and are similar to those that have occurred in the Study Area for decades.

The Final Supplemental EIS/OEIS supports the request for federal regulatory permits and authorizations under the Marine Mammal Protection Act and the Endangered Species Act. The Final Supplemental EIS/OEIS includes an analysis of training and testing activities using new, relevant information available after the release of the 2015 MITT Final EIS/OEIS. New information includes more recent marine mammal density data and new scientific information.
