Congress Mandates Destruction of Outdated Chemical WeaponsU.S. Signs International Chemical Weapons Convention TreatyDisposal of Stockpiled Chemical Warfare AgentsDisposal of Nonstockpiled Chemical Warfare AgentsThe amount of stockpiled chemical warfare agents in the United States is thought to have reached nearly 40,000 tons by 1968.

During Operation Cut Holes and Sink ‘Em (CHASE) from 1967 to 1970, thousands of tons of unwanted chemical warfare agents and ammunition were disposed of by loading them onto old ships that then were intentionally sunk at sea. In 1970, Congress passed PL 91-121/441 (50 USC 1521). This law directed what is now the Department of Health and Human Services (HHS) and the Office of the Surgeon General (OSG) to review plans made by the Department of Defense (DoD) to transport, test or dispose of lethal chemical agents, and to recommend actions to protect the public’s health and safety during such activities. Congress passed Public Law (PL) 92-532 (33 USC 1401) in 1972because of environmental concern about dumping chemical weapons in t...Get price
