Title 49 - Transportation
(a) For vessel transportation of each non-bulk packaging that contains a marine pollutant— (1) If the proper shipping name for a material which is a marine pollutant does not identify by name the component which makes the material a marine pollutant, the name of that component must be marked on the package in parentheses in association with the marked proper shipping name. Where two or more components which make a material a marine pollutant are present, the names of at least two of the components most predominantly contributing to the marine pollutant designation must appear in parentheses in association with the marked proper shipping name; and (2) The MARINE POLLUTANT mark shall be placed in association with the hazard warning labels required by subpart E of this part or, in the absence of any labels, in association with the marked proper shipping name. (b) A bulk packaging that contains a marine pollutant must— (1) Be marked with the MARINE POLLUTANT mark on at least two opposing sides or two ends other than the bottom if the packaging has a capacity of less than 3,785 L (1,000 gallons). The mark must be visible from the direction it faces. The mark may be displayed in black lettering on a square-on-point configuration having the same outside dimensions as a placard; or (2) Be marked on each end and each side with the MARINE POLLUTANT mark if the packaging has a capacity of 3,785 L (1,000 gallons) or more. The mark must be visible from the direction it faces. The mark may be displayed in black lettering on a square-on-point configuration having the same outside dimensions as a placard. (c) A transport vehicle or freight container that contains a package subject to the marking requirements of paragraph (a) or (b) of this section must be marked with the MARINE POLLUTANT mark. The mark must appear on each side and each end of the transport vehicle or freight container, and must be visible from the direction it faces. This requirement may be met by the marking displayed on a freight container or portable tank loaded on a motor vehicle or rail car. This mark may be displayed in black lettering on a white square-on-point configuration having the same outside dimensions as a placard. (d) The MARINE POLLUTANT mark is not required— (1) On a combination package containing a severe marine pollutant (see appendix B to §172.101), in inner packagings each of which contains: (i) 0.5 L (17 ounces) or less net capacity for liquids; or (ii) 500 g (17.6 ounces) or less net capacity for solids. (2) On a combination packaging containing a marine pollutant, other than a severe marine pollutant, in inner packagings each of which contains: (i) 5 L (1.3 gallons) or less net capacity for liquids; or (ii) 5 kg (11 pounds) or less net capacity for solids. (3) Except for transportation by vessel, on a bulk packaging, freight container or transport vehicle that bears a label or placard specified in subparts E or F of this part. (e) MARINE POLLUTANT mark. The MARINE POLLUTANT mark must conform to the following: (1) Except for size, the MARINE POLLUTANT mark must appear as follows: (2) The symbol, letters and border must be black and the background white, or the symbol, letters, border and background must be of contrasting color to the surface to which the mark is affixed. Each side of the mark must be— (i) At least 100 mm (3.9 inches) for marks applied to: (A) Non-bulk packagings, except in the case of packagings which, because of their size, can only bear smaller marks; or (B) Bulk packagings with a capacity of less than 3785 L (1,000 gallons); or (ii) At least 250 mm (9.8 inches) for marks applied to all other bulk packagings. (f) Exceptions. See §171.4(c).
