Which agency is primarily responsible for UXO clearance in the United States?

The U.S. Army Corps of Engineers is primarily responsible for UXO clearance in the United States because it has the expertise and authority to manage and execute remediation projects related to hazardous materials, including unexploded ordnance. The Corps plays a significant role in addressing environmental remediation and public safety concerns, particularly at former military installations and sites where military training activities have taken place. Their experience includes the assessment, removal, and safe disposal of UXO to protect people and the environment.

In contrast, the Environmental Protection Agency focuses on environmental protection and regulations but does not specifically handle UXO clearance. The Federal Bureau of Investigation is primarily concerned with law enforcement and national security, with no direct responsibility for ordnance clearance. The Department of Defense oversees military operations and policies but delegates the actual clearance operations to specialized entities such as the U.S. Army Corps of Engineers.
