Counties: employees and officers; brown alert for dangerous levels of sewage or E. coli; require. Amends 1976 PA 390 (MCL 30.401 - 30.421) by adding sec. 10a.

Summary

HB4427 amends Michigan’s Emergency Management Act to create a new “brown alert” requirement for county-level public notification when dangerous levels of E. coli are found in waters within a county due to a combined sewer overflow or sanitary sewer overflow. If a county health officer or designee determines that water contains E. coli above the bill’s threshold, they must notify the county emergency management coordinator within 12 hours. The coordinator must then issue a Wireless Emergency Alerts message to county residents within 12 hours of receiving notice. The alert must identify the location of the contamination and describe the health risks of exposure. The bill defines a dangerous level of E. coli as more than 300 E. coli per 100 milliliters and applies to county health officers, including those serving multiple counties. In practical terms, the bill creates a formal emergency communication process for sewage-related water contamination events and adds a new public warning mechanism to state law.

Impact

The bill adds section 10a to the Emergency Management Act, expanding the statute to require rapid public notification for sewage-related E. coli contamination in county waters. It imposes new duties on county health officers or their designees and county emergency management coordinators, and it authorizes use of the Wireless Emergency Alerts system for these notices. The measure affects county health departments, emergency management offices, and residents who may use or be exposed to affected waterways.

Sentiment

The available voting history suggests broad support for the bill. It was reported from committee 14-0 with a substitute and later passed the House 94-10 with immediate effect, indicating strong bipartisan agreement that the public should be warned quickly about contaminated water. No committee transcript is available, but the vote totals suggest the bill was generally viewed favorably as a public health and safety measure.

Contention

The main policy issue appears to be whether the state should mandate a specific alerting process and timeline for sewage-related water contamination. Support is implied by the strong votes, likely grounded in public health protection, transparency, and rapid warning to residents. Any opposition, reflected in the 10 no votes on House third reading, may have centered on implementation concerns, the use of emergency alert systems for localized water quality problems, or the administrative burden on county officials, though no recorded discussion is available to confirm those points.
