Waterways - HMT Appendix B

Marine pollutants are identified in Appendix B, List of Marine Pollutants. These materials could cause significant damage if released into the ocean. The marine pollutant requirements apply to all marine pollutants transported by vessel. Each shipper must determine if the material is a marine pollutant.

Appendix B contains two columns. Column 1 is labeled "S.M.P." for Severe Marine Pollutants and Column 2 is labeled "Marine Pollutant." If the material is a marine pollutant, it will be listed in Column 2 of Appendix B. If the letters "PP" appear in Column 1, the material listed in Column 2 is a Severe Marine Pollutant (S.M.P.).
