Activity Completion Report No. 6: Completion of Removal of Phase 2 Treated Materials, Dismantling, Site Restoration, and Demobilization

6 Completion of Removal of Phase 2 Treated Materials, Dismantling, Site Restoration, and Demobilization was submitted on December 19, 2018. The report was prepared by CDM International, Inc. for review by the United States Agency for International Development. The Danang Airport Environmental Remediation project aimed to address contamination resulting from the use of Agent Orange during the Vietnam War. The project involved the removal of Phase 2 treated materials, dismantling of infrastructure, site restoration, and demobilization of personnel. The remediation process was overseen by CDM International, Inc. in collaboration with the United States Agency for International Development. The report outlines the disposition process, which included the establishment of residual dioxin action levels, identification of materials, and development of procedures for non-hazardous and hazardous waste disposal. The project involved the dismantling of the IPTD treatment system, IPTD structure emptying and dismantling, and LVTP system dismantling. The site restoration process included the removal of hazardous waste storage areas, concrete storage areas, and office trailers. The report highlights the importance of health and safety protocols, which included training, medical monitoring, and blood dioxin monitoring. The project also implemented a lessons learned section, which identified key takeaways from the remediation process. The conclusions section summarizes the project's achievements and recommendations for future remediation efforts. The project's geographic focus was on the Danang Airport site in Vietnam, with a time frame spanning several years. The report provides detailed information on the project's implementation, including the removal of over 1,000 tons of contaminated soil and the dismantling of infrastructure. The project's success was measured through the reduction of dioxin levels and the restoration of the site to a safe and environmentally sound condition. The report's recommendations emphasize the importance of thorough planning, effective communication, and rigorous health and safety protocols in large-scale remediation projects. The project's achievements serve as a model for future environmental remediation efforts, particularly in areas contaminated by hazardous substances.
