Summary: In 2020, the Michigan Department of Licensing and Regulatory Affairs adopted regulations requiring health facilities to implement a water management program.
Key Provisions:
Requirement for a Legionella Maintenance Plan
The Michigan regulations require that “A health facility must implement a water management program that follows the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) Standard 188-2018 -- Legionellosis: Risk Management for Building Water Systems.” The regulations further require health facilities to utilize the Centers for Disease Control and Prevention (CDC) best practice guidance on water management, including the “CDC Toolkit: Developing a Water Management Program to Reduce Legionella Growth and Spread in Buildings,” which is adopted by reference in the regulations.
Other Specific Requirements
The regulations require generally that the “water management program must include a facility risk assessment, control measures, and ongoing verification of the program.”
If secondary treatment of the public water system is incorporated as part of the water management program, the health facility must comply with state laws and regulations governing safe drinking water.
