Utilities and Infrastructure Maryland 3 Minutes Read · published February 08, 2026 Flag of Maryland

Baltimore, Maryland businesses that discharge or allow runoff to reach the municipal storm sewer must follow city stormwater rules and report illicit discharges. This guide explains who enforces the rules, typical violations, how enforcement and appeals work, reporting steps, and where to find official forms and contacts so businesses can comply with Baltimore stormwater requirements.

Penalties & Enforcement

The City of Baltimore Department of Public Works (DPW) administers the city stormwater program and investigates illicit discharges. Official guidance and complaint/reporting procedures are maintained by DPW (DPW Stormwater)[1].

  • Fines and civil penalties: amounts not specified on the cited page.
  • Escalation: first, repeat, and continuing offence procedures not specified on the cited page.
  • Non-monetary sanctions: enforcement records indicate orders to abate, stop-work or corrective actions and potential court referral; specific remedies or suspension terms are not specified on the cited page.
  • Enforcer and complaint pathway: Baltimore DPW receives reports, conducts inspections, and issues enforcement; use the DPW stormwater contact or report page to initiate a complaint.[1]
  • Appeals and review: appeal routes and statutory time limits are not specified on the cited page; request procedural information from DPW when notified of an enforcement action.
Report spills and illegal discharges immediately to minimize enforcement risk.

Common violations and typical outcomes reported by municipal stormwater programs include:

  • Discharging automotive fluids, chemicals, or concentrated wash water to streets or storm drains; enforcement often begins with an order to remediate.
  • Improper industrial or construction site controls leading to sediment or pollutant runoff; may trigger corrective action plans.
  • Failure to maintain required best management practices (BMPs) or permits; may result in notices, penalties, or stop-work directives.

Applications & Forms

DPW publishes guidance and online reporting for illicit discharges; specific permit forms or numbered applications tied to illicit discharge enforcement are not listed on the cited page. Businesses should contact DPW for any required permits, remediation plans, or formal application instructions.[1]

If a formal permit or variance is required, DPW will identify the document and submission route during enforcement or pre-application contact.

How Enforcement Works

When DPW receives a report or discovers a discharge, inspectors typically document the incident, order immediate containment or cleanup, and may require follow-up monitoring or permanent fixes. Enforcement often involves written notices, timelines to comply, and potential referral to administrative or judicatory proceedings when compliance is not achieved.

Action Steps for Businesses

  • Report the incident to Baltimore DPW using the stormwater contact/report link.[1]
  • Document actions taken, photos, and witness information; preserve records in case of follow-up.
