Notice requirements for water discharges modified.

This bill modifies Minnesota's water pollution reporting rules by requiring facilities that discharge pollutants to notify downstream users, including public water systems and Tribal governments, after informing state agencies. The law exempts discharges of five gallons or less of petroleum from immediate notification requirements while maintaining other pollution prevention duties. Facilities must use efficient communication methods like phone calls, social media, or signage to warn impacted areas about the discharge date, material type, and potential health risks. The state agency will also provide guidance on how to deliver these timely notifications effectively.
