When must the public be noticed of a Tier 2 violation?

• A. within 30 days
• B. within 24 hours
• C. within 6 months
• D. within 12 months

Answer: (A)

Public notification timelines for Tier 2 violations require notice within 30 days of discovery. This timing reflects a balance between getting important information to the community promptly and having enough time to verify details and assess potential risks. A 30-day window ensures residents and local authorities are informed so they can take appropriate precautions or actions if needed, without waiting so long that opportunities to protect public health or the environment are lost. Notifying within 24 hours would belong to an immediate emergency level (Tier 1), while waiting 6 or 12 months would delay crucial information and could undermine trust and proper response. The 30-day requirement helps communicate the issue clearly, outline any potential impacts, and describe corrective steps and contact points.
