Public notification uses a tiered approach to match the urgency of the issue with the required response time. For less serious noncompliance or monitoring/reporting violations that do not pose an immediate health threat, the rule sets the longest window: public notice must be issued within 12 months. This longer timeframe reflects the lower risk level, while still ensuring that customers are informed about issues in a timely manner. In contrast, notices for more serious concerns require much quicker communication, so those timelines are shorter. Therefore, the appropriate timeframe for Tier 3 is within 12 months.
