Within what timeframe must Tier 2 public notice be issued?

• A. Within 24 hours.
• B. Within 7 days.
• C. Within 30 days.
• D. Within 12 months.

Answer: (C)

Public notification under the Safe Drinking Water Act uses a tiered approach so the urgency of the message matches the level of risk. Tier 2 covers non-emergency issues that may affect water quality or compliance but don’t pose an immediate health threat. Because these aren’t immediate emergencies, the rule requires the notice to be issued within 30 days after the system learns of the violation, giving enough time to prepare clear information and any corrective actions. This balances keeping the public informed with allowing the utility to communicate specifics like the nature of the issue, potential health considerations, and steps residents should take. For context, Tier 1 notices go out within 24 hours for emergencies, and Tier 3 notices within 12 months for certain non-health-based or administrative items.
