Legislative Update: Governor Hochul Signs New Cooling Tower Compliance Legislation

AWT Legislative & Regulatory Update

Governor Kathy Hochul has signed legislation amending NYC Administrative Code §28-317.3, further strengthening New York City’s cooling tower compliance and Legionella prevention requirements. The law requires twice-yearly cooling tower certifications, accelerated notification and remediation timelines for public health hazards, and increased penalties for non-compliance.

Why This Matters to AWT Members

This legislation will directly affect AWT members who provide water treatment, Legionella risk management, cooling tower maintenance, monitoring, and compliance services within New York City. Building owners and operators will face additional regulatory obligations, creating a greater need for documented inspections, water management practices, testing protocols, corrective actions, and compliance support. The enhanced requirements further reinforce the critical role water treatment professionals play in protecting public health and helping facilities remain compliant. [governor.ny.gov], [nyc.gov]

Members are encouraged to review the new requirements and discuss any necessary adjustments to service programs, reporting practices, and client communications to ensure continued compliance. [governor.ny.gov], [nyc.gov]
