U.S. troops took command of Camp Hialeah on 17 September 1945 and remained until the end of 1948 when control of the installation passed to the U.S. Consulate and the United Nations.

Busan port facilities were under the control of the U.S. military to handle the enormous support requirements of the fighting forces, with the 8069th Replacement Depot operating Camp Hialeah.

[3] After the Korean Armistice Agreement was signed on 27 July 1953, most of the Busan port facilities were turned over to the ROK government.

Under the guidelines of the U.S.–South Korea Status of Forces Agreement (SOFA), comparable facilities that comply with U.S. standards and infrastructure are required to ensure quality of life for U.S. soldiers and families prior to installation relocation.

On 1 June 2005, pursuant to the Amended Land Partnership Plan between the U.S. and the Republic of Korea, it was announced that Camp Hialeah would close.
