In addition to the previous requirements for discharging trash on state or federally controlled waters, all vessels on marine waters south of Interstate Highway 10 (I-10) also must:
- Have on board a clearly marked, closed container for proper disposal of waste, trash, and other garbage. Closed containers must be sealed and of sufficient size for the number of people on board and length of the cruise. Examples of closed containers include clearly labeled cans with lids or watertight garbage bags with appropriate ties.
- Display a sign informing all on board that it is illegal to dispose of waste, trash, and other garbage into the marine waters of Mississippi.
