Final answer:
Exemptions to the normal transportation requirements for hazardous waste can be made during emergency situations to protect human health or the environment.
Step-by-step explanation:
Normal transportation requirements for hazardous waste (HW) can be exempted in emergency situations. The United States Department of Transportation hazardous materials regulations, along with the Environmental Protection Agency's hazardous waste regulations, usually apply when transporters move hazardous waste on public roads, highways, rails, and waterways. However, during emergency situations, when immediate action is required to protect human health or the environment, certain exemptions can be made to facilitate rapid response and mitigation.
