Final answer:
Department of Defense units outside the US may be subject to the Resource Conservation and Recovery Act, which deals with the lifecycle management of hazardous waste, but this is complex and can depend on international agreements and host country laws.
Step-by-step explanation:
The question asks whether Department of Defense (DoD) units located outside the United States are subject to the Resource Conservation and Recovery Act (RCRA). The RCRA provides a framework for hazardous waste management, ensuring that hazardous waste is managed safely throughout its entire lifecycle (cradle to grave), which includes its creation, transportation, treatment, storage, and eventual disposal. The regulation details extend to hazardous waste recycling, regulations that apply to treatment, storage, and disposal facilities, and descriptions of land disposal restrictions. While the RCRA provides clear guidelines within the United States, the application of these regulations for DoD units outside the US is complex and potentially subject to international agreements and the laws of host countries. Typically, DoD operations must comply with US environmental laws unless explicitly exempted or where the application of such laws is not feasible due to operational requirements.
