What is the maximum distance, in nautical miles, from shore that overboard discharge of fuel contamination may occur?

The maximum distance from shore where overboard discharge of fuel contamination may occur is set at 50 nautical miles, as specified in various regulatory frameworks and maritime guidelines. This regulation aims to protect marine environments from pollutants that can be harmful to aquatic life and ecosystems. Discharging fuel or other contaminants beyond this distance is typically regulated to minimize the risk of impacting coastal waters and habitats.

Understanding this regulation is crucial for machinist mates and other maritime personnel, as it underscores their responsibilities in managing fuel and ensuring compliance with environmental protection standards. This knowledge is integral not only for maintaining operational readiness but also for upholding environmental stewardship while at sea.
