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 draft supplement to the 2015 Final Mariana Islands Training and Testing Final Environmental Impact Statement/Overseas Environmental Impact Statement (EIS/OEIS). The Navy is assessing the potential environmental impacts associated with ongoing military readiness activities, which include training and research, development, testing, and evaluation (referred to as “training and testing”) activities conducted within the MITT Study Area (referred to as the “Study Area”).
The supplement to the 2015 analysis supports ongoing and future activities conducted at sea and on Farallon de Medinilla (FDM) within the Study Area beyond 2020. Proposed activities are similar to those that have been conducted in the Study Area for decades.
The Supplemental EIS/OEIS supports the issuance of federal regulatory permits and authorizations under the Marine Mammal Protection Act and the Endangered Species Act. The Navy used new, relevant information to reanalyze the impacts of training and testing activities. New information includes an updated underwater sound effects model, more recent marine mammal and sea turtle density data, and new science.
Watch an informational video about the importance of Navy training and testing in the Mariana Islands Training and Testing EIS/OEIS Study Area.
