SUPPLEMENTARY INFORMATION:

DoN and Coast Guard's Proposed Action is to conduct military readiness training activities, and research, development, testing, and evaluation activities in the AFTT Study Area. These military readiness activities include the use of active sonar and explosives within existing range complexes and testing ranges and additional areas located in the Atlantic Ocean along the eastern coast of North America, in portions of the Caribbean Sea, the Gulf of Mexico, at Navy pierside locations and port transit channels, near civilian ports, and in bays, harbors, and inland waterways ( e.g., the lower Chesapeake Bay). These military readiness activities are generally consistent with those analyzed in the AFTT EIS/OEIS completed in 2018 and are representative of training and testing that the Navy has been conducting in the AFTT Study Area for decades. Since the completion of the 2018 Final EIS/OEIS, the best available science has been updated, the regulatory environment has changed, the Study Area has changed, and what is known about our impacts has been refined. All of this has been incorporated into this Supplemental EIS/OEIS analysis. The National Oceanic and Atmospheric Administration's National Marine Fisheries Service (NMFS) is a Cooperating Agency for the Supplemental EIS/OEIS.

The purpose of the Proposed Action is to ensure the Action Proponents, including the Coast Guard, are able to organize, train, and equip service members and personnel to meet their respective national defense missions in accordance with their Congressionally mandated requirements.

Potential direct, indirect, cumulative, short-term, long-term, irreversible, and irretrievable impacts to the environment from two action alternatives and a No Action Alternative are evaluated in the Draft Supplemental EIS/OEIS. Resources evaluated in detail include air quality, sediments and water quality, vegetation, invertebrates, marine habitats, fish, marine mammals, sea turtles and other marine reptiles, and birds and bats.

Based on the results of the analysis, the DoN and Coast Guard have requested from NMFS a Letter of Authorization in accordance with the Marine Mammal Protection Act to authorize the incidental take of marine mammals that may result from the implementation of the activities analyzed in the AFTT Draft Supplemental EIS/OEIS. In accordance with Section 7 of the Endangered Species Act, DoN and Coast Guard are consulting with NMFS and U.S. Fish and Wildlife Service for potential impacts to federally listed species. DoN and Coast Guard will complete all required consultations and comply with all applicable laws and regulations.

The Draft Supplemental EIS/OEIS addresses mitigation measures designed to help reduce or avoid potential impacts to marine resources, including new mitigation measures that include expanded location-specific mitigations and updates to activity-based mitigation measures. In addition, the Draft Supplemental EIS/OEIS addresses marine species monitoring efforts designed to track compliance with authorizations and to investigate the effectiveness of mitigation measures implemented as part of the Proposed Action. The proposed mitigation measures would be implemented under either action alternative to maximize the mitigation benefits to the environment.

Mitigation measures are being coordinated through the consultation and permitting processes. DoN and Coast Guard will also consider public ( printed page 77114) comments on proposed mitigation measures described in this Draft Supplemental EIS/OEIS.

Comments submitted during the public comment period at the in-person public meetings, electronically via the project website, or mailed to the address provided in the ADDRESSES section will become part of the public record. Substantive comments will be considered in the development of the Final Supplemental EIS/OEIS.
