Title 33 - Navigation and Navigable Waters
As used in this subpart: Certifying entity means an individual or organization accepted by the Commandant (G-MSO) to review plans and calculations for vapor control system designs, and to conduct initial inspections and witness tests of vapor control system installations. Existing vapor control system means a vapor control system which was operating prior to July 23, 1990. Facility vapor connection means the point in a facility's vapor collection system where it connects to a vapor collection hose or the base of a vapor collection arm. Inerted means the oxygen content of the vapor space in a tank vessel's cargo tank is reduced to 8 percent by volume or less in accordance with the inert gas requirements of 46 CFR 32.53 or 46 CFR 153.500. Liquid knockout vessel means a device to separate liquid from vapor. Maximum allowable transfer rate means the maximum volumetric rate at which a vessel may receive cargo or ballast. New vapor control system means a vapor control system which is not an existing vapor control system. 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 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, and includes the vapor collection system and the vapor processing unit. Vapor destruction unit means a vapor processing unit that destroys cargo vapor by a means such as incineration. Vapor dispersion system means a vapor processing unit which releases cargo vapor to the atmosphere through a venting system not located on the vessel being loaded or ballasted. Vapor processing unit means the components of a vapor control system that recovers, destroys, or disperses vapor collected from a vessel. Vapor recovery unit means a vapor processing unit that recovers cargo vapor by a non-destructive means such as lean oil absorbtion, carbon bed adsorption, or refrigeration. Vessel vapor connection means the point in a vessel's fixed vapor collection system where it connects to a vapor collection hose or arm.
