Purpose

To update and strengthen how notices are given when a discharge could pollute Minnesota waters. The change aims to ensure agencies and downstream communities, including tribal governments and drinking water facilities, are quickly informed and can respond to protect public health and water quality.

Main Provisions

• Duty to notify the agency: The bill keeps the requirement that any person must immediately notify the agency if a discharge occurs that could pollute waters of the state. The responsible party must work to recover spilled material quickly and take steps to minimize pollution.

• Small discharge exception: If the discharge is five gallons or less of petroleum, notifying the agency is not required under the main duty to notify. This exception does not remove the other obligations to recover and minimize pollution.

• Downstream notice requirement: After notifying the agency, the owner of a publicly owned treatment works (POTW) or a publicly or privately owned sewer system must promptly notify potentially impacted downstream users. This includes public Tribal governments and downstream drinking water facilities that may be affected. Notifications should use the most efficient method available (in person, telephone, radio, social media, web page, or other quick means).

• Signage and area notices: The notice must include the discharge date and time, a description of the material, a warning about potential public health risk, and the permittee’s contact information. If applicable, signage must be posted at impacted public use areas, or the entity with jurisdiction over those areas must be notified.

• Agency guidance: The agency must provide guidance on timing and methods for giving timely notice, including protocols for how notices should be delivered.

Notable Changes to Law

• Adds a formal requirement to inform downstream communities, including tribal governments and downstream drinking water facilities, after a discharge is reported to the agency.
• Specifies multiple rapid communication channels to use for notices (in person, phone, radio, social media, web page, etc.) and requires clear, public-facing content in the notices.
• Requires signage or jurisdictional notification to ensure impacted public areas are informed.
• Introduces an explicit duty for the agency to publish guidance on timely notice procedures.

Practical Impact

• Polluters and water managers must coordinate with downstream communities more quickly.
• Tribal governments and drinking water facilities gain faster access to discharge information, helping protect water supplies.
• Public health risk information will be communicated through clear, prompt notices and visible signage.

Implementation Notes

• The small petroleum discharge exception creates a threshold where agency notification is not required, but other responsibilities (recovery, pollution control) still apply.
• The requirement to provide guidance from the agency helps standardize how notices are issued across different incidents and jurisdictions.
