This guide explains how Baltimore enforces stormwater and illicit discharge rules, where to file complaints, what evidence to collect, and the likely enforcement steps. It summarizes the responsible department, available online reporting channels, typical sanctions or the absence of specified fines on official pages, and practical action steps for homeowners, contractors, and property managers. Use the links and contacts to submit complaints and follow up on investigations.

How to identify an illegal storm drain discharge

Illegal discharges include anything other than stormwater entering storm drains or outfalls: visible sheens, colored runoff, paint, sewage, oily films, sediments from construction, or persistent dye. Note time, location (nearest address or intersection), and take dated photos or video from multiple angles; collect water samples only if safe.

Take photos and note GPS or nearest address before leaving the scene.

Reporting channels and responsible office

The City of Baltimore Department of Public Works (DPW) is the primary agency that manages stormwater infrastructure and investigates illicit discharges. Report pollution and illicit discharges through Baltimore 311 online or by phone; the DPW receives and triages these reports for field response.[1][2]

  • Use Baltimore 311 to submit a pollution complaint with photos and location details.[3]
  • Contact DPW Stormwater operations for follow-up on active investigations.

Penalties & Enforcement

Enforcement authority for illicit discharges rests with Baltimore City agencies, primarily the Department of Public Works and any enforcement bodies designated in the City Code. Where specific penalty amounts, escalation rules, or continuing-offence fines are set, they are published in the city code or enforcement notices; where amounts are not listed on the cited page, this guide states that fact and cites the source.

  • Enforcer: Department of Public Works (and other city enforcement offices as identified in the City Code).[2]
  • Monetary fines: not specified on the cited page.
  • Escalation: first, repeat, and continuing-offence procedures are not specified on the cited page.
  • Non-monetary sanctions: orders to cease discharge, abatement orders, clean-up orders, and referral to environmental or civil court are available remedies under city enforcement practice, though exact procedures or time limits are not specified on the cited page.
  • Inspections: DPW inspects reported sites and documents violations; complaint submission via 311 triggers an operational response.
  • Appeal/review: processes and statutory time limits for appeal are not specified on the cited page.
If you believe a discharge presents an immediate health hazard, call emergency services before filing a routine complaint.

Applications & Forms

There is no specific public "illicit discharge complaint" form published on the cited DPW informational pages; complaints are submitted through Baltimore 311 or by direct DPW contact. If permits or variances are relevant (for construction-related runoff), those are handled through DPW or Building/Planning permitting channels and require separate applications listed on official permit pages.[1]

Action steps — What to do now

  • Document: take dated photos/videos, note location, time, weather, and any visible source.
  • Report: submit a 311 service request with attachments and request DPW follow-up.[3]
  • Preserve evidence: keep originals of photos, witness names, and any correspondence.
  • Follow up: note the 311 ticket number and request status updates from DPW.
Keeping a clear photo record and the 311 ticket number speeds enforcement and remediation.
