ASAN, Guam (March 28, 2019) – The U.S. Navy extended the public comment period by 15 days from April 2, to April 17, for the Mariana Islands Training and Testing Supplemental Environmental Impact Statement.

The Navy requests and welcomes substantive public comments on the Draft Supplemental EIS/OEIS.

The Proposed Action is to conduct at-sea training and testing activities within the Study Area. These activities include the use of active sonar and explosives while employing marine species mitigation measures. The purpose of the Proposed Action, which remains the same as the 2015 MITT Final EIS/OEIS, is to maintain a ready force to ensure the military can accomplish its mission to maintain, train, and equip combat-ready forces.

The proposed at-sea training and testing activities are generally consistent with those analyzed in the 2015 MITT Final EIS/OEIS and are similar to activities the military has conducted in the Study Area for decades.
