Question 17General Subjects - Assistant Engineer

The correct answer is D) Perform a complete ballast water exchange in an area no less than 200 nautical miles from any shore prior to discharging ballast in U.S. waters. This is the correct answer because the U.S. Coast Guard's ballast water management regulations allow for ballast water exchange as an acceptable means of compliance, as long as it is conducted at least 200 nautical miles from any shore. The other options, such as 3, 12, or 25 nautical miles, are not compliant with the federal regulations. Conducting a complete ballast water exchange at least 200 nautical miles from shore helps to minimize the risk of introducing invasive species into U.S. waters.
