Releases and hazardous waste site situations that pose imminent and substantial danger to human health and the environment are covered under which EPA program?

• A. Hazardous Materials Response
• B. Risk Assessment and Cleanup
• C. Environmental Restoration
• D. Emergency Response

Answer: (D)

Emergency Response is the EPA program dedicated to situations where a release or hazardous waste site poses an imminent and substantial danger to human health and the environment. The focus is rapid action to assess the threat, contain and mitigate the release, protect people and ecosystems, and coordinate with state, local, and other federal partners. This immediate-response mission distinguishes it from longer-term cleanup efforts or planning processes. Environmental Restoration deals with cleaning up sites after the immediate danger is controlled, and Risk Assessment and Cleanup describes evaluating risks and planning remediation rather than responding in the moment. Hazardous Materials Response is related to hazmat handling in broader contexts, but the agency’s formal program for urgent threats is Emergency Response.
