Navy Intends to Use New Acoustic Model to Assess Marine Mammal Effects
On January 16, 2013, the U.S. Department of the Navy published Federal Register notice of its intent to prepare a supplement to the 2011 Gulf of Alaska Navy Training Activities Environmental Impact Statement/Overseas Environmental Impact Statement. This SEIS/OEIS will support authorization of incidental takes of marine mammals under the Marine Mammal Protection Act and incidental takes of threatened and endangered marine species under the Endangered Species Act. These federal regulatory permits and authorizations expire in May 2016. The Navy will evaluate new, relevant information and incorporate that information into revised analyses where appropriate.

The SEIS/OEIS will also analyze data using an acoustic model not available for the 2011 EIS/OEIS, the Navy Acoustics Effects Model, to estimate potential marine species effects.

The Navy has requested that the U.S. National Marine Fisheries Service be a cooperating agency in preparation of this SEIS/OEIS. Public scoping meetings will not be held, but public comments will be accepted during the scoping period from January 16, 2013 to March 18, 2013.
