(a) Except as specified in §172.030, each vessel that loads grain in bulk must have a Document of Authorization issued in accordance with one of the following: (1) Section 3 of the International Code for the Safe Carriage of Grain in Bulk if the Document of Authorization is issued on or after January 1, 1994. As used in the Code, the term “Administration” means “U.S. Coast Guard”. (2) Regulation 10 part (a) of the Annex to IMO Assembly resolution A.264(VIII) if the Document of Authorization was issued before January 1, 1994. (b) The Commandant recognizes the National Cargo Bureau, Inc., 30 Vesey Street, New York, NY 10007–2914, for the purpose of issuing Documents of Authorization in accordance with paragraph (a)(1) of this section. (a) Certain material is incorporated by reference into this part under approval of the Director of the Federal Register under 5 U.S.C. 552(a) and 1 CFR part 51.

International Maritime Organization (IMO) Publications Section, 4 Albert Embankment, London, SE1 7SR United Kingdom. Amendment to Chapter VI of the International Convention for the Safety of Life at Sea, 1960, Resolution A.264(VIII)—172.015 Publication No. 240–E, International Code for the Safe Carriage of Grain in Bulk—172.015 [CGD 95–028, 62 FR 51218, Sept. 30, 1997, as amended by USCG–1998–4442, 63 FR 52192, Sept. 30, 1998; 69 FR 18803, Apr. 9, 2004] (a) Vessels are exempt from 172.015 on voyages between: (1) United States ports along the East Coast as far south as Cape Henry, VA; (2) Wilmington, NC and Miami, FL; (3) United States ports in the Gulf of Mexico; (4) Puget Sound ports and Canadian west coast ports or Columbia River ports, or both; (5) San Francisco, Los Angeles, and San Diego, CA. (b) Vessels exempt by paragraph (a) of this section must comply with the following conditions: (1) The master is satisfied that the vessel's longitudinal strength is not impaired. (2) The master ascertains the weather to be encountered on the voyage. (3) Potential heeling moments are reduced to a minimum by carrying as few slack holds as possible. (4) Each slack surface must be leveled. (5) The transverse metacentric height (GM), in meters, of the vessel throughout the voyage, after correction for liquid free surface, has been shown by stability calculations to be in excess of the required GM (GMR), in meters. (i) The GMR is the sum of the increments of GM (GMI) multiplied by the correction factor, f and r.
Where: r=(available freeboard) (beam) of the vessel and f=1 if r is > 0.268 or f=(0.268 r) if r is < 0.268. (ii) The GMI for each compartment which has a slack surface of grain, i.e., is not trimmed full, is calculated by the following formula: GMI=(B3×L×0.0661)(Disp.×SF))
where: B=breadth of slack grain surface (m L=Length of compartment (m) Disp.=Displacement of vessel (tons) SF=Stowage factor of grain in compartment (cubic meters/tons) (c) Vessels which do not have the Document of Authorization required by §172.015 may carry grain in bulk up to one third of their deadweight tonnage provided the stability complies with the requirements of Section 9 of the International Code for the Safe Carriage of Grain in Bulk. (a) Before it sails, each vessel that loads grain in bulk, except vessels engaged solely on voyages on the Great Lakes, rivers, or lakes, bays, and sounds, must have a certificate of loading issued by an organization recognized by the Commandant for that purpose. The certificate of loading may be accepted as prima facie evidence of compliance with the regulations in this subpart. (b) The Commandant recognizes the National Cargo Bureau, Inc., 30 Vesey Street, New York, NY, 10007–2914, for the purpose of issuing certificates of loading.
