Operation Pacer IVY

Operation Pacer Ivy was a 1972 operation of the U.S. Air Force that removed Agent Orange from South Vietnam and stored it on Johnston Atoll. IVY was presumably selected as an abbreviation of InVentorY.Operation Pacer HO refers to an associated program of the United States Department of Defense (DoD), dealing with the disposition of Agent Orange from Vietnam.

On 15 April 1970, the Assistant Secretary of Defense suspended the use of Herbicide Orange (HO), a defoliant spray mixture during the Vietnam War. The suspension lasted from April 15, 1970, to September 13, 1971. On September 13, 1971, the Secretary directed the Chairman of the Joint Chiefs of Staff that “all stocks of Herbicide Orange in Vietnam will be returned to the Continental United States as quickly as practicable for disposition. A joint State Department and Defense Department message has been prepared requesting the U.S. Embassy negotiate with the Government of Republic of Vietnam for the return to U.S. control of all stocks of Herbicide Orange in Vietnam.” Based on this directive, the 7th Air Force in Vietnam initiated Operation PACER IVY, the removal of all Herbicide Orange in Vietnam to Johnston Island.

Another problem arose with the movement and storage of Herbicide Orange from Vietnam. In 1971,Congress passed The Foreign Military Sales Act Amendment (Public Law 91-672) to prohibit the transportation of chemical weapons from the Island of Okinawa to Umatilla Chemical Depot during Operation Red Hat. In addition, the law prohibited the transfer of nerve agent, mustard agent, agent orange and other chemical munitions located in other countries into all 50 U.S. states.
