Section XII-1907 - Tier 2 Public Notice

A. When a Tier 2 public notice is required under the national primary drinking water regulations, §358 C of this Part, the public water system shall, unless directed otherwise by the Office of Public Health in writing, provide public notification in a daily or weekly newspaper serving the area as soon as possible but no later than 14 days after the violation or failure. In addition to newspaper notice, a notice shall also be provided to the consumers by direct mail or hand delivery within 30 days after the violation or failure.

EXCEPTION: When furnishing a notice to a newspaper is deemed not feasible for a non-community water system, continuous posting (in conspicuous places within the area served by the system) and, if available, e-mailing (to students or employees, for example) may be substituted. The notice shall remain posted for a minimum of at least 7 days.
