Question 58 ONC03 - Master LT 500-1600 GRT

The Correct Answer is A. ### Explanation of Correct Option (A) Option A ("Outside of 3nm") is correct because it aligns with the provisions of MARPOL ANNEX V, Regulation 4, which governs the discharge of garbage outside of special areas. Specifically, Regulation 4.1.2.2 states that the discharge of **food wastes** that have been comminuted or ground (i.e., passed through a screen no larger than 25 mm) is permitted when the ship is **as far as practicable from the nearest land, but in any case, not less than 3 nautical miles** from the nearest land. ### Explanation of Incorrect Options **B) Outside of 6nm:** This option is incorrect. While 6 nm is often a relevant distance for certain discharges (like non-ground food waste), it is not the minimum required distance for discharging *ground* food waste outside of a special area. The minimum distance for ground food waste is 3 nm. **C) Outside of 12nm:** This option is incorrect. 12 nm is the minimum distance required for discharging certain other types of garbage outside of special areas (e.g., cargo residues that cannot be recovered). It is also the requirement for discharging *un-ground* food waste in some scenarios. However, for ground food waste, the required minimum distance is 3 nm. **D) Outside of 25nm:** This option is incorrect. 25 nm is the distance generally associated with discharging certain cleaning agents, additives, or substances from cargo holds and external surfaces if they contain substances harmful to the marine environment, but it is not the requirement for ground food garbage. It is an overly restrictive distance for the disposal of processed food waste outside of special areas.
