Which statement best describes a Tier 3 violation?

• A. Other violations not covered by Tier 1 or Tier 2, usually minor monitoring/testing issues.
• B. Violations with immediate health risk.
• C. Violations requiring 24-hour notice.
• D. Violations causing water shutdown.

Answer: (A)

Tier classifications organize violations by urgency and potential health impact. Tier 1 covers the most serious issues with immediate health risk or urgent notification, Tier 2 includes significant violations that still require prompt notice or have notable health implications, and Tier 3 is the catch‑all for other violations not covered by the first two tiers, usually minor monitoring or testing issues. So the statement that Tier 3 encompasses other violations not covered by Tier 1 or Tier 2, typically minor monitoring/testing issues, best fits the tier’s purpose. The other descriptions describe issues with greater risk or urgency—situations that belong in the higher tiers rather than Tier 3.
