1. How soon after learning of a violation must a PWS give public notification to its customers?

• For Tier 1 violations (Acute MCL or treatment technique violations) within 24 hours.
• For Tier 2 violations (monthly MCL violations under the TCR) within 30 days.
• For Tier 3 violations (monitoring or reporting violations) within 12 months.

2. Can I distribute my public notices for a monitoring or maximum contaminant level (MCL) violations with my yearly Consumer Confidence Reports (CCR)?

Yes, if all required elements of the public notification are included in either the text of the CCR or an attached separate notice page and a printed copy of the CCR and public notification are made available to all users of the water supply whether or not they have access to a computer. Please note that CCR notices may only be a secondary method for publicizing MCL violations that occurred in the previous calendar year.
