The U.S. Coast Guard announced on Tuesday that will not remove over 300 navigational aids from northeastern waters.

The Coast Guard District Northeast announced in April its plan to modernize its system of navigational aids — many of which were deployed before modern GPS systems became seaworthy.

Nearly 150 of the aids that were to be removed are located off Maine’s coast.

Maritime stakeholders had criticized the plan, as had Sens. Susan Collins, R-Maine, and Angus King, I-Maine, and Rep. Chellie Pingree, D-1st District.

In June, Collins, King and eight of their fellow New England senators wrote a letter to acting Commandant Kevin Lunday, asking him to hold off on the removal plan, while Pingree led a group of nine bipartisan U.S. House members in sending Lunday a similar letter.

In August, the Coast Guard announced it would put the plan on pause, and in September, it initiated a public comment period.

Over 3,200 comments were submitted, the Northeast Coast Guard District said in a statement Tuesday night.

Instead of removing the buoys, the northeast branch of the Coast Guard will conduct further analysis of its plan to modernize its system.

“We are extremely appreciative of the public’s input on this important project, and our team’s hard work, analysis and conclusions were reinforced by the outstanding feedback we received from our maritime stakeholders,” said Rear Adm. Michael Platt, the Coast Guard Northeast District commander.

The Coast Guard said, however, that it still intends to modernize its navigational aid system in northeastern waters while ensuring mariners’ safety and security.

“We remain focused on shaping the future of our waterways, ensuring a modern aids to navigation system, and facilitating commerce vital to economic prosperity and strategic mobility,” Platt said.
