United States Army Danger Zone; Salt River, Rolling Fork River, and Otter Creek; U.S. Army Garrison, Fort Knox Military Reservation; Fort Knox, KY

The Corps of Engineers is amending its regulations to establish a danger zone on navigable portions of the Salt River and the Rolling Fork River and the non-navigable portions of Otter Creek, within the installation boundaries of the Fort Knox Military Reservation. These regulations will enable the Army to prohibit public access to the area and enhance safety and security within active military impact and training areas. The Salt River passes through an active military area. Unexploded ordnance (UXO) from military weapons firing is located within the areas along the river and a multi-purpose digital training range is under construction in this area. The Salt River is also used for river training activities. Training and military weapons firing activities occur approximately 320 days per year in this area. The Rolling Fork River passes through the center of the Yano Multi-purpose Training Range. Weapons firing from artillery, M1A2 Abrams Tanks, Bradley Fighting Vehicles, helicopters, and other weapons systems occur approximately 320 days of each year. Otter Creek runs through the installation. Otter Creek travels through Training Areas 8, 9, and 10. These areas are used to train soldiers for combat operation training on M1A2 Abrams Tanks and Bradley Fighting Vehicles. Artillery simulators and other explosive devices are used for these training activities, presenting a risk to civilians entering the area. These regulations are necessary to protect the public from potentially hazardous conditions that may exist as a result of Army use and security of the area. The regulations will also safeguard government personnel and property from sabotage and other subversive acts, accidents, or incidents of similar nature.
