Report an Environmental Concern

This is a photo of polluted runoff coming from an outfall pipe.
Polluted runoff is seen when it discharges from
outfall pipes.

Citizen reports of environmental problems are a great complement to regular monitoring programs. You can provide surveillance at a level beyond that of the monitoring staff. Citizens often can provide immediate local information that increases the chance of eliminating illicit connections to pipes in the storm drain system.


An environmental emergency poses an immediate threat to public health as well as the environment. Examples of emergencies include:

  • Fish kills
  • Chemical spills
  • Sewage overflows

Call the Maryland Department of the Environment Emergency Response Division at 1-866-633-4686 if you observe a chemical spill or fish kill. This number is serviced 24 hours a day.

Report sewage discharges to the Baltimore County Department of Public Works and Transportation by calling 410-887-7415. This number is serviced 24 hours a day.


A concern is a problem that could have negative impacts on the environment, such as trash dumping or discharging wash water to a storm drain. To learn more about stream pollution, visit these other County web pages:
