  • USAID and Office 33 sign a Memorandum of Understanding establishing the framework for the Danang Airport Remediation Project.
  • USAID begins preparing an Environmental Assessment (EA) to assess the extent of dioxin contamination and approaches to remediate Danang Airport.


  • USAID completes the EA that recommended thermal desorption as most effective available and scientifically proven technology, for the remediation of Danang Airport.
  • USAID and MND sign a Memorandum of Intent for implementation of the Danang Airport Remediation Project.


  • The Prime Minister of Vietnam and MND approve plans for the Danang Airport Remediation Project.
  • MND clears unexploded ordnance from the remediation site and submits Environmental Impact Assessment (EIA) on the technology selection and project plan to the Vietnamese Ministry of Natural Resources and Environment (MONRE) for review.


  • MONRE approved the EIA in May 2012. 
  • USAID and MND launch the implementation of the Danang Airport Remediation Project on August 9, 2012.
