Utilities and Infrastructure Minnesota 3 Minutes Read · published February 09, 2026 Flag of Minnesota

In Minneapolis, Minnesota, property owners must promptly report any spill or discharge into storm drains or public right-of-way to limit pollution and comply with city rules. This guide explains what to report, who enforces stormwater and illicit-discharge rules, typical penalties, and clear steps to report and remediate spills for residential and commercial property owners.

What to report and when

Report any visible fluids, sediment, wash water, oil, chemicals, or other materials entering a storm drain, gutter, street, curb, or waterbody immediately. Note the location, time, estimated volume, and any identifying features such as vehicle license or business name.

  • Visible oil, gasoline, or chemical sheen on stormwater or surface water.
  • Large amounts of paint, concrete washout, or sediment entering a gutter or drain.
  • Continuous flows from a property to the storm system that are not normal runoff.
  • Any spill observed lasting more than a few minutes or recurring discharges.
Report immediately by phone if the spill is active or poses a health risk.

Penalties & Enforcement

The Minneapolis Code of Ordinances addresses illicit discharges, stormwater protection, and public-right-of-way pollution; consult the Code for the controlling provisions and enforcement authorities. Minneapolis Code of Ordinances[1]

Specific monetary fines, escalation rules, and exact section numbers are not always summarized on the cited consolidated code page; where amounts or procedures are not published there, the code or implementing rules should be consulted directly and the city may provide a current penalty schedule.

  • Fines: not specified on the cited page; see the Code or contact enforcement for current amounts.
  • Escalation: first, repeat, and continuing offence procedures: not specified on the cited page.
  • Non-monetary sanctions: stop-work or abatement orders, cleanup directives, civil enforcement, and referral to court are permitted under city authority.
  • Enforcer: City of Minneapolis Public Works and related municipal enforcement divisions handle stormwater and illicit-discharge complaints; report via 311 or the Public Works contact channels listed below.
  • Appeals and review: appeal routes vary by enforcement instrument; time limits and procedures are specified in the ordinance or enforcement notice—if not provided on the notice, contact the issuing department for appeal deadlines.
  • Defences/discretion: the city code may allow exceptions for permitted discharges or where a reasonable excuse applies; permit or variance processes are handled by the relevant city office.
If you receive an enforcement notice, act quickly to meet deadlines for cleanup or appeal.

Applications & Forms

No universal, single-purpose city spill-reporting form is published on the consolidated ordinance page; the usual procedure is to report spills by phone or the city reporting portal and follow up with the department for any required remediation plans or permit applications. Contact the Public Works or 311 intake for any form names or submittal instructions.

Action steps for property owners

  • Immediate: Stop or contain the source if safe, prevent further runoff, and protect drains.
  • Report: Call 311 or the Public Works emergency number to report the spill and provide location details and photos.
  • Document: Keep records of response actions, contractor invoices, and communications with the city.
  • Comply: Complete cleanup orders or permit-based remediation; request extensions or appeals in writing if needed.
Documenting your response reduces the risk of escalated enforcement or fines.

FAQ

Do I need to call 911 for a storm drain spill?
Call 911 only for immediate threats to life or fire; for pollution or non-emergency spills, call 311 or the City Public Works reporting line.
Will I be fined for an accidental spill?
Penalties depend on the ordinance and enforcement discretion; specific fine amounts are not specified on the cited consolidated code page and should be confirmed with enforcement.
