The marine pollutant requirements, specified under the HMR,
apply to all marine pollutants transported by vessel; but do not
apply to nonbulk shipments transported by air, rail, or
highway. Marine pollutants are identified in Appendix B of the
HMT. Each shipper must determine if the material is a marine
pollutant. Let’s try an example. See if Copper cyanide, is a
marine pollutant by checking to see if it is listed in Appendix B
to §172.101, List of Marine Pollutants. As you can see it is,
now check to see if Copper cyanide is a proper shipping name
found in the HMT. It is in the HMT, thus Copper cyanide is a
marine pollutant, and Copper cyanide is the proper shipping
name to be used. For more information on the definition of a
marine pollutant, please click on the book icon in the right
corner of the screen and select §171.8; or for marine pollutant
exceptions, select §171.4.
