The National Environmental Policy Act (NEPA) requires federal agencies to evaluate a range of reasonable alternatives to achieve the purpose of and need for the Proposed Action. Using the most current and best available science and analytical methods, the Navy evaluated the potential environmental impacts of three alternatives, including a No Action Alternative, in the Draft Supplemental EIS/OEIS.
In the Supplemental EIS/OEIS, the Navy:

Implementation of any action alternative may affect certain species, but is not expected to decrease the overall health or survival of any population. Almost all predicted effects are behavioral responses and would cause no injury or mortality.
Avoiding impacts from at-sea training and testing on the marine environment is an important goal for the Navy. The Navy employs standard operating procedures and protective measures during sonar use as well as additional event-specific mitigation measures.
The Office of the Assistant Secretary of the Navy (Energy, Installations, and Environment) is the decision maker regarding the selection and implementation of an alternative. The decision is based on many factors, including the details of the environmental analyses, breadth of public comment, recommendations from Navy commands, and mission requirements.
The Navy requests and actively solicits feedback and comments from the public, government agencies, elected officials, and nongovernmental organizations. Substantive public comments will be considered and incorporated into the Final Supplemental EIS/OEIS, as applicable. Additionally, several federal and state agencies have regulatory authority and oversee Navy activities in the Study Area.
The Navy is accepting comments on the Draft Supplemental EIS/OEIS through June 12, 2019
