You are here: EIS/OEIS > Background

The United States (U.S.) Navy has prepared an Environmental Impact Statement (EIS)/Overseas Environmental Impact Statement (OEIS) to evaluate the potential environmental effects associated with the continuation of military readiness training and research, development, test and evaluation activities (referred to as “training and testing”) conducted in the Mariana Islands Training and Testing (MITT) Study Area. The MITT Study Area is comprised of air, land, and sea space and includes the existing Mariana Islands Range Complex (MIRC), its surrounding seas, and a transit corridor between the MIRC and the Navy’s Hawaii Range Complex where training and testing activities may occur. The MIRC is the only Navy range complex in the MITT Study Area.


The MITT EIS/OEIS is the reevaluation and reauthorization of training and testing activities reviewed in the MIRC EIS/OEIS, which the Navy completed with community input in 2010. The Navy is consulting with the National Marine Fisheries Service and the U.S. Fish and Wildlife Service to renew these authorizations.
