Marine Pollutant Marking: When is it Required?
If you ever had to deal with the Hazardous Materials Regulations (HMR) or have shipped hazardous materials before, then you know how confusing the HMR can be. If you don't know, I'll save you some time, it can give you a pretty big migraine. Unfortunately, the marine pollutant requirements within the HMR aren't any easier to decipher. Hopefully, I can untangle the mess of regulations regarding the marine pollutant requirements enough to make your job a little easier, or at least save you some time. Let's take a look at the marine pollutant requirements.
Requirements
In general, the HMR requires any non-bulk or bulk packaging that contains a marine pollutant to display the marine pollutant marking. For non-bulk packages, the marking must be displayed near the hazard warning label and/or the proper shipping name. For bulk packages, the marking must be displayed on two opposing sides or ends when package capacity is under 1,000 gallons. For bulk packages with a capacity 1,000 gallons or more, the marking must be displayed on each side and each end.
Exceptions
The HMR contains numerous exceptions, and lucky for you, there are a couple for the marine pollutant marking. The marine pollutant marking is not required:
- On a non-bulk packaging when transported by highway, rail, or aircraft.
- On a packaging displaying the limited quantity marking.
- On a single or combination packaging containing a net quantity per single or inner packaging of 1.3 gallons or less for liquids or having a net mass of 11 pounds or less for solids.
- On a bulk packaging, freight container, or transport vehicle that displays a label or placard when transported by highway, rail, or aircraft.
The exceptions are only for the display of marine pollutant markings. If the material in your package meets any other requirements in the HMR, the applicable markings, labels, or placards may still be required.
Simplified
Now that we have the requirements and exceptions for the marine pollutant marking listed, let's see if we can simplify it even more.
Most non-bulk packages with a capacity greater than 1.3 gallons for liquids and 11 pounds for solids only need to display the marine pollutant marking if the material is a marine pollutant and it is transported by vessel. If the marine pollutant is in a non-bulk package and transported by highway, rail, or aircraft, the marine pollutant marking does not need to be displayed.
Bulk packages of marine pollutants transported by vessel must display the marine pollutant marking. If the bulk package is transported by highway, rail, or aircraft and is labeled or placarded, then the marine pollutant marking is not required to be displayed. However, if your bulk package is not labeled or placarded when transported by highway, rail, or aircraft, then you must display the marine pollutant marking.
Key to remember: The HMR requires that packages containing a marine pollutant to display the marine pollutant marking. However, exceptions within the HMR make it so the marine pollutant marking is only required to be displayed when transported by vessel for all packages and by highway, rail, and aircraft for bulk packages that do not display a label or placard.
