STEP 3: Report Pollution

If you see oil or marine debris, you can use our mobile app to report it to the National Response Center.

If you are using a mobile phone you can chose to call them directly through the app by pressing the “call NRC” button. The app will dial the NRC and also display your current GPS coordinates so you can make an accurate and detailed verbal report.

You can also report digitally by pressing the “Report Oil Spill” or “Report Marine Debris” buttons. This will take you to the advanced reporting tool.

STEP 4: Reporting

Here you can take and upload a photo and then work through the reporting options to describe the oil spill or marine debris you have discovered.

When you report an oil spill using the Marine Defenders mobile app, we will post your report online and send your contact information, your description of the incident, and GPS coordinate to the National Response Center.

The NRC will alert the Coast Guard and send them to investigate.

If you are not in a cell phone service area, your device will store the information and report it once you are back in range.

Alert! If you are a responsible party – please call the NRC directly. The Marine Defenders mobile app does not relieve you of your legal reporting requirements. Please see our Terms of Use.
