Public comment on draft environmental assessment for permit for cable through Marianas Trench Marine National Monument

RTI Solutions, Inc. has requested a Right-of-Way permit from the U.S. Fish and Wildlife Service to install a submarine fiber optic telecommunications cable connecting Japan, Guam, and Australia that would pass through the Trench Unit of Marianas Trench Marine National Monument.  The cable, proposed to be laid directly on the seabed through the Monument, would provide telecommunications interconnectivity between Guam and Australia.

The Service is seeking public review and comment on the draft Environmental Assessment that evaluates the effects of the Service issuing a Right-of-Way permit for the proposed cable through the Monument.  The EA will be available for public comment from June 12 to July 12.
