Which organization is responsible for funding ATON structure repairs?

The correct answer highlights the role of the Civil Engineering Unit (CEU) in conjunction with the Allocation of Funds within the Department of the Army, specifically with reference to AFC43. CEUs are specialized branches of the U.S. Army Corps of Engineers that provide engineering services, including maintenance and repairs of shore-based aids to navigation (ATON) structures.

Under the AFC43 funding designation, the CEU manages budget allocations specifically aimed at infrastructure projects that enhance navigational safety and efficiency. This structure allows for a focused approach in ensuring that critical ATON systems—such as buoys, beacons, and lighthouses—are maintained in optimal working condition. This ensures the continued safety of maritime navigation which is essential for commercial and recreational marine traffic.

The involvement of USCG Headquarters, the Department of Transportation (DOT), and FEMA does not directly oversee the funding and structural repairs of ATON systems as CEUs do, making the CEU with AFC43 the more relevant authority in this context.
