Title 46 - Shipping
(a) Except as specified by paragraph (c) of this section, this part applies to each tank vessel operating in the navigable waters of the United States, when collecting vapors of crude oil, gasoline blends, or benzene emitted from a vessel's cargo tanks through a vapor control system. (b) A tank vessel which transfers vapors of flammable or combustible cargoes other than crude oil, gasoline blends, or benzene, to a facility covered by 33 CFR part 154 must meet the requirements prescribed by the Commandant (G-MSO). (c) A tank vessel with an existing vapor collection system specifically approved by the Coast Guard for the collection of cargo vapor which was operating prior to July 23, 1990, is subject only to §39.30–1 and §39.40–5 of this part as long as it transfers cargo vapor only to the specific facilities for which it was approved. (d) This part does not apply to the collection of vapors of liquefied flammable gases as defined in §30.10–39 of this subchapter. [CGD 88–102, 55 FR 25446, June 21, 1990, as amended by CGD 95–072, 60 FR 50462, Sept. 29, 1995; CGD 96–041, 61 FR 50727, Sept. 27, 1996] As used in this part: Cargo deck area means that part of the weather deck that is directly over the cargo tanks. Existing vapor collection system means a vapor collection system which was operating prior to July 23, 1990. Facility vapor connection means the point in a facility's fixed vapor collection system where it connects with the vapor collection hose or the base of the vapor collection arm. Independent as applied to two systems means that one system will operate with a failure of any part of the other system except power sources and electrical feeder panels. Inerted means the oxygen content of the vapor space in a cargo tank is reduced to 8 percent by volume or less in accordance with the inert gas requirements of §32.53 or §153.500 of this chapter. Lightering or lightering operation means the transfer of a bulk liquid cargo from a tank vessel to a service vessel. Marine Safety Center means the Commanding Officer, U.S. Coast Guard Marine Safety Center, 400 Seventh Street, SW., Washington, DC 20590–0001. Maximum allowable transfer rate means the maximum volumetric rate at which a vessel may receive cargo or ballast. New vapor collection system means a vapor collection system which is not an existing vapor collection system. Service vessel means a vessel which transports bulk liquid cargo between a facility and another vessel. Topping-off operation means the transfer of a bulk liquid cargo from a service vessel to another vessel in order to load the receiving vessel to a deeper draft. Vapor balancing means the transfer of vapor displaced by incoming cargo from the tank of a vessel receiving cargo into a tank of the vessel or facility delivering cargo via a vapor collection system. Vapor collection system means an arrangement of piping and hoses used to collect vapor emitted from a vessel's cargo tanks and to transport the vapor to a vapor processing unit. Vapor control system means an arrangement of piping and equipment used to control vapor emissions collected from a vessel. It includes the vapor collection system and vapor processing unit. Vapor processing unit means the components of a vapor control system that recovers, destroys, or disperses vapor collected from a vessel. Vessel vapor connection means the point in a vessel's fixed vapor collection system where it connects with the vapor collection hose or arm. (a) Certain materials are incorporated by reference into this part with the approval of the Director of the Federal Register in accordance with 5 U.S.C. 552(a). To enforce any edition other than the one listed in paragraph (b) of this section, notice of change must be published in the (b) The material approved for incorporation by reference in this part, and the sections affected are: [CGD 88–102, 55 FR 25446, June 21, 1990, as amended by CGD 95–072, 60 FR 50462, Sept. 29, 1995; CGD 96–041, 61 FR 50727, Sept. 27, 1996; CGD 97–057, 62 FR 51043, Sept. 30, 1997; USCG-1999–5151, 64 FR 67177, Dec. 1, 1999] Each vessel which has a vapor processing unit located on board must meet the requirements of 33 CFR part 154, subpart E to the satisfaction of the Commandant (G-MSO) in addition to complying with the requirements of this part. [CGD 88–102, 55 FR 25446, June 21, 1990, as amended by CGD 95–072, 60 FR 50462, Sept. 29, 1995; CGD 96–041, 61 FR 50727, Sept. 27, 1996] (a) A person in charge of a transfer operation utilizing a vapor collection system must have completed a training program covering the particular system installed on the vessel. Training must include drills or demonstrations using the installed vapor control system covering normal operations and emergency procedures. (b) The training program required by paragraph (a) of this section must cover the following subjects: (1) Purpose of a vapor control system; (2) Principles of the vapor control system; (3) Components of the vapor control system; (4) Hazards associated with the vapor control system; (5) Coast Guard regulations in this part; (6) Operating procedures, including: (i) Testing and inspection requirements, (ii) Pre-transfer procedures, (iii) Connection sequence, (iv) Start-up procedures, and (v) Normal operations; and (7) Emergency procedures. [CGD 88–102, 55 FR 25446, June 21, 1990; 55 FR 39270, Sept. 26, 1990] (a) Plans, calculations, and specifications for a new vessel vapor collection system must be submitted to the Marine Safety Center for approval prior to installation. (b) An existing vapor collection system installation that has been Coast Guard approved to transfer cargo vapor to specific facilities must be reviewed and approved by the Marine Safety Center prior to transferring vapors to other facilities. (c) The owners/operators of a foreign flag vessel may submit certification by the classification society which classes the vessel that the vessel meets the requirements of this part as an alternative to meeting the requirements in paragraph (a) of this section. (d) Upon satisfactory completion of plan review and inspection of the vapor collection system or receipt of the certification provided for in paragraph (c) of this section, the Officer in Charge, Marine Inspection, shall endorse the Certificate of Inspection for U.S. flag vessels, or the Certificate of Compliance for foreign flag vessels, that the vessel is acceptable for collecting the vapor from crude oil, gasoline blends, and benzene, or any other vapor it is found acceptable to collect.
