      Unless specifically defined in the Texas Clean Air Act (TCAA) or in the rules of the Texas Natural Resource Conservation Commission (commission), the terms used by the commission have the meanings commonly ascribed to them in the field of air pollution control.  In addition to the terms which are defined by the TCAA, the following terms, when used in this chapter, shall have the following meanings, unless the context clearly indicates otherwise.  Additional definitions for terms used in this chapter are found in §101.1 of this title (relating to Definitions) and §3.2 of this title (relating to Definitions).

            (1)  Beaumont/Port Arthur area - Hardin, Jefferson, and Orange Counties.

            (2)  Capture efficiency - The amount of volatile organic compounds (VOC) collected by a capture system which is expressed as a percentage derived from the weight per unit time of VOC entering a capture system and delivered to a control device divided by the weight per unit time of total VOC generated by a source of VOC.

            (3)  Carbon adsorption system - A carbon adsorber with an inlet and outlet for exhaust gases and a system to regenerate the saturated adsorbent.

            (4)  Component - A piece of equipment, including, but not limited to pumps, valves, compressors, and pressure relief valves, which has the potential to leak VOC.

            (5)  Continuous monitoring - Any monitoring device used to comply with a continuous monitoring requirement of this chapter will be considered continuous if it can be demonstrated that at least 95% of the required data is captured.

            (6)  Covered attainment counties - Anderson, Angelina, Aransas, Atascosa, Austin, Bastrop, Bee, Bell, Bexar, Bosque, Bowie, Brazos, Burleson, Caldwell, Calhoun, Camp, Cass, Cherokee, Colorado, Comal, Cooke, Coryell, De Witt, Delta, Ellis, Falls, Fannin, Fayette, Franklin, Freestone, Goliad, Gonzales, Grayson, Gregg, Grimes, Guadalupe, Harrison, Hays, Henderson, Hill, Hood, Hopkins, Houston, Hunt, Jackson, Jasper, Johnson, Karnes, Kaufman, Lamar, Lavaca, Lee, Leon, Limestone, Live Oak, Madison, Marion, Matagorda, McLennan, Milam, Morris, Nacogdoches, Navarro, Newton, Nueces, Panola, Parker, Polk, Rains, Red River, Refugio, Robertson, Rockwall,  Rusk, Sabine, San Jacinto, San Patricio, San Augustine, Shelby, Smith, Somervell, Titus, Travis, Trinity, Tyler, Upshur, Van Zandt, Victoria, Walker, Washington, Wharton, Williamson, Wilson, Wise, and Wood Counties.

            (9)  External floating roof - A cover or roof in an open-top tank which rests upon or is floated upon the liquid being contained and is equipped with a single or double seal to close the space between the roof edge and tank shell.  A double seal consists of two complete and separate closure seals, one above the other, containing an enclosed space between them.  For the purposes of this chapter (relating to Control of Air Pollution from Volatile Organic Compounds), an external floating roof storage tank which is equipped with a self-supporting fixed roof (typically a bolted aluminum geodesic dome) shall be considered to be an internal floating roof storage tank.

            (10)  Fugitive emission - Any VOC entering the atmosphere which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening designed to direct or control its flow.

            (11)  Gasoline bulk plant - A gasoline loading and/or unloading facility, excluding marine terminals, having a gasoline throughput less than 20,000 gallons (75,708 liters) per day, averaged over each consecutive 30-day period.  A motor vehicle fuel dispensing facility is not a gasoline bulk plant.

            (12)  Gasoline terminal - A gasoline loading and/or unloading facility, excluding marine terminals, having a gasoline throughput equal to or greater than 20,000 gallons (75,708 liters) per day, averaged over each consecutive 30-day period.

            (13)  Houston/Galveston area - Brazoria, Chambers, Fort Bend, Galveston, Harris, Liberty, Montgomery, and Waller Counties.

            (14)  Incinerator - For the purposes of this chapter (relating to Control of Air Pollution from Volatile Organic Compounds), an enclosed control device that combusts or oxidizes VOC gases or vapors.

            (15)  Internal floating cover - A cover or floating roof in a fixed roof tank which rests upon or is floated upon the liquid being contained, and is equipped with a closure seal or seals to close the space between the cover edge and tank shell.  For the purposes of this chapter (relating to Control of Air Pollution from Volatile Organic Compounds), an external floating roof storage tank which is equipped with a self-supporting fixed roof (typically a bolted aluminum geodesic dome) shall be considered to be an internal floating roof storage tank.

            (16)  Liquefied petroleum gas - Any material that is composed predominantly of any of the following hydrocarbons or mixtures of hydrocarbons:  propane, propylene, normal butane, isobutane, and butylenes.

            (17)  Leak-free marine vessel - A marine vessel whose cargo tank closures (hatch covers, expansion domes, ullage openings, butterworth covers, and gauging covers) were inspected prior to cargo transfer operations and all such closures were properly secured such that no leaks of liquid or vapors can be detected by sight, sound, or smell.  Cargo tank closures shall meet the applicable rules or regulations of the marine vessel's classification society or flag state.  Cargo tank pressure/vacuum valves shall be operating within the range specified by the marine vessel's classification society or flag state and seated when tank pressure is less than 80% of set point pressure such that no vapor leaks can be detected by sight, sound, or smell.  As an alternative, a marine vessel operated at negative pressure is assumed to be leak-free for the purpose of this standard.

            (18)  Marine loading facility - The loading arm(s), pumps, meters, shutoff valves, relief valves, and other piping and valves that are part of a single system used to fill a marine vessel at a single geographic site.  Loading equipment that is physically separate (i.e., does not share common piping, valves, and other loading equipment) is considered to be a separate marine loading facility.

            (19)  Marine loading operation - The transfer of oil, gasoline, or other volatile organic liquids at any affected marine terminal, beginning with the connections made to a marine vessel and ending with the disconnection from the marine vessel.

            (20)  Marine terminal - Any marine facility or structure constructed to load oil, gasoline, or other volatile organic liquid bulk cargo into a marine vessel.  A marine terminal consists of one or more marine loading facilities.

            (21)  Natural gas/gasoline processing - A process that extracts condensate from gases obtained from natural gas production and/or fractionates natural gas liquids into component products, such as ethane, propane, butane, and natural gasoline.  The following facilities shall be included in this definition if, and only if, located on the same property as a natural gas/gasoline processing operation previously defined:  compressor stations, dehydration units, sweetening units, field treatment, underground storage, liquified natural gas units, and field gas gathering systems.

            (22)  Petroleum refinery - Any facility engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel oils, lubricants, or other products through distillation of crude oil, or through the redistillation, cracking, extraction, reforming, or other processing of unfinished petroleum derivatives.

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

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

            (25)  Synthetic organic chemical manufacturing process - A process that produces, as intermediates or final products, one or more of the chemicals listed in 40 Code of Federal Regulations 60.489 (effective October 18, 1983).  See NOTE TO READER at end of Section.

            (26)  Tank-truck tank - Any storage tank having a capacity greater than 1,000 gallons, mounted on a tank-truck or trailer.  Vacuum trucks used exclusively for maintenance and spill response are not considered to be tank-truck tanks.

            (27)  Transport vessel - Any land-based mode of transportation (truck or rail) that is equipped with a storage tank having a capacity greater than 1,000 gallons which is used to transport oil, gasoline, or other volatile organic liquid bulk cargo.  Vacuum trucks used exclusively for maintenance and spill response are not considered to be transport vessels.

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

            (29)  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.

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

            (31)  Vapor-tight - Not capable of allowing the passage of gases at the pressures encountered except where other acceptable leak-tight conditions are prescribed in this chapter.

            (32)  Waxy, high pour point crude oil - A crude oil with a pour point of 50 degrees Fahrenheit (10 degrees Celsius) or higher as determined by the American Society for Testing and Materials Standard D97-66, "Test for Pour Point of Petroleum Oils."
