If a township, or any department or agency of the township, issues a boil order, then the township must notify any certified local public health department that serves an area subject to the boil order as soon as is practical, but no later than 2 hours after issuing the order. In addition to the initial notice, the township must provide, to any affected certified local public health department, a written notification within 24 hours after issuing the boil order. The written notification must include the estimated duration of the order or warning and the geographic area covered by the order or warning.
