     (27)  Polymer and resin manufacturing process - A process that produces any of the following polymers or resins:  polyethylene, polypropylene, polystyrene, and styrenebutadiene latex.

     (28)  Printing line - An operation consisting of a series of one or more printing processes and including associated drying areas.

     (29)  Publication rotogravure printing - Any rotogravure printing upon paper which is subsequently formed into books, magazines, catalogues, brochures, directories, newspaper supplements, or other types of printed materials.

     (30)  Rotogravure printing - The application of words, designs, and/or pictures to any substrate by means of a roll printing technique which involves a recessed image area.  The recessed area is loaded with ink and pressed directly to the substrate for image transfer.

     (31)  Synthetic Organic Chemical Manufacturing Industry (SOCMI) batch distillation operation - A SOCMI noncontinuous distillation operation in which a discrete quantity or batch of liquid feed is charged into a distillation unit and distilled at one time.  After the initial charging of the liquid feed, no additional liquid is added during the distillation operation.

     (32)  Synthetic Organic Chemical Manufacturing Industry (SOCMI) batch process - Any SOCMI noncontinuous reactor process which is not characterized by steady-state conditions, and in which reactants are not added and products are not removed simultaneously.

     (33)  Synthetic Organic Chemical Manufacturing Industry (SOCMI) distillation operation - A SOCMI operation separating one or more feed stream(s) into two or more exit streams, each exit stream having component concentrations different from those in the feed stream(s).  The separation is achieved by the redistribution of the components between the liquid and vapor-phase as they approach equilibrium within the distillation unit.

     (34)  Synthetic Organic Chemical Manufacturing Industry (SOCMI) distillation unit - A SOCMI device or vessel in which distillation operations occur, including all associated internals (including, but not limited to, trays and packing), accessories (including, but not limited to, reboilers, condensers, vacuum pumps, and steam jets), and recovery devices (such as absorbers, carbon adsorbers, and condensers) which are capable of, and used for, recovering chemicals for use, reuse, or sale.

     (35)  Synthetic Organic Chemical Manufacturing Industry (SOCMI) reactor process - A SOCMI unit operation in which one or more chemicals, or reactants other than air, are combined or decomposed in such a way, that their molecular structures are altered and one or more new organic compounds are formed.

     (39)  True partial pressure - The absolute aggregate partial pressure (psia) of all VOC in a gas stream.

     (40)  Vapor balance system - A system which provides for containment of hydrocarbon vapors by returning displaced vapors from the receiving vessel back to the originating vessel.

     (41)  Vapor combustor - A partially enclosed combustion device, where the combustion flame may be partially visible, but at no time does the device operate with a fully visible flame.  A vapor combustor is used to destroy VOCs to the destruction requirements defined in the applicable emission specifications and control requirements sections of this chapter by smokeless combustion without extracting energy in the form of process heat or steam.  Auxiliary fuel and/or a flame air control damping system, which can operate at all times to control the air/fuel mixture to the combustor's flame zone, may be required to ensure smokeless combustion during operation.

     (42)  Vapor control system - Any control system which utilizes vapor collection equipment to route VOC to a control device that reduces VOC emissions.

     (43)  Vapor recovery system - Any control system which utilizes vapor collection equipment to route VOC to a control device that reduces VOC emissions.
