ATON / Proposed Notice of Change
ATON/Proposed Notice of Change Location: 32-56.39N 079-55.48W Aid Name: Cooper River Range D/F Front Light LLNR: 3040 Action: CHANGE Action Type Change Light Signals The U.S. Coast Guard is proposing the following changes to the Aids to Navigation System in the Cooper River: Cooper River Range D Rear Light (LLNR 3045) will be permanently relocated to approximate position 32-56.45N 079-55.35W. Cooper River Range D/F Front Light (LLNR 3040) will have the flash characteristic changed from a Q W to a FL W 2.5s. The light will continue to be an all-around light. Due to the current location of Cooper River Range D Rear Light (LLNR 30465) being inaccessible for a Coast Guard asset to effectively repair the structure, it was determined by relocating the rear range approximately 400 feet further from its current location will offer a much improved range quality and allow CG personnel to service at any tidal state. All comments should be emailed to: [email protected] or [email protected] with Cooper River Range D/F as the subject line. Comments can also be mailed to Commander (dpw), Seventh Coast Guard District, 909 SE 1st Ave (STE 406) Brickell Plaza Federal Building, Miami, FL. 33131-3050 to be received by March 16, 2026.
