Under the bioterrorism-related act, a drinking water utility serving more than how many people must perform vulnerability assessment updates or complete an emergency response plan and certify to USEPA?

• A. Bioterroism, 3,300
• B. Cyber Terrorism, 3,300
• C. Physical Terrorism, 10,000
• D. Chemical Terrorism, 10,000

Answer: (A)

The requirement comes from the Bioterrorism Preparedness and Response Act, which targets biological threats to drinking water. The regulation specifies that a community water system serving more than a certain number of people must conduct vulnerability assessments, update or complete an emergency response plan, and certify to the USEPA. The scenario described—a water utility serving more than 3,300 people—fits this act precisely, so it must perform vulnerability assessment updates or finalize its emergency response plan and submit certification to the EPA.

The other options mix in different types of threats (cyber, physical, chemical) that aren’t the basis for this particular bioterrorism-related requirement, and the population thresholds listed (such as 10,000) do not apply to this statute.
