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) announces its intent to prepare a supplement to the 2015 Final Mariana Islands Training and Testing Environmental Impact Statement/Overseas Environmental Impact Statement (EIS/OEIS) to assess the potential environmental impacts associated with ongoing military readiness activities, which include 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”).
The supplement to the 2015 Final EIS/OEIS is being prepared to support ongoing and future activities conducted at sea and on Farallon de Medinilla (FDM) within the Study Area beyond 2020. This Supplemental EIS/OEIS will include an analysis of military readiness activities using new information available after the release of the 2015 Final EIS/OEIS. New information includes an updated acoustic effects model, updated marine mammal density data, and evolving and emergent best available science. Military readiness activities are generally consistent with those analyzed in the 2015 Final EIS/OEIS and are representative of training and testing the military has conducted in the Study Area for decades.
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 ongoing military readiness activities within the Study Area beyond 2020.
