(C) waste materials that result from activities associated with the exploration, development, or production of oil or gas, or geothermal resources, and other substance or material regulated by the Railroad Commission of Texas under the Natural Resources Code, §91.101, unless the waste, substance, or material results from activities associated with gasoline plants, natural gas liquids processing plants, pressure maintenance plants, or repressurizing plants and is hazardous waste as defined by the administrator of the EPA under the federal Solid Waste Disposal Act, as amended by RCRA, as amended (42 United States Code, §§6901 et seq.).
(91) Sour crude - A crude oil which will emit a sour gas when in equilibrium at atmospheric pressure.
(92) Sour gas - Any natural gas containing more than 1.5 grains of hydrogen sulfide per 100 cubic feet, or more than 30 grains of total sulfur per 100 cubic feet.
(93) Source - A point of origin of air contaminants, whether privately or publicly owned or operated. Upon request of a source owner, the executive director shall determine whether multiple processes emitting air contaminants from a single point of emission will be treated as a single source or as multiple sources.
(94) Special waste from health care related facilities - A solid waste which if improperly treated or handled may serve to transmit infectious disease(s) and which is comprised of the following: animal waste, bulk blood and blood products, microbiological waste, pathological waste, and sharps.
(95) Standard conditions - A condition at a temperature of 68 degrees Fahrenheit (20 degrees Centigrade) and a pressure of 14.7 pounds per square inch absolute (101.3 kiloPascals). Pollutant concentrations from an incinerator will be corrected to a condition of 50% excess air if the incinerator is operating at greater than 50% excess air.
(96) Standard metropolitan statistical area - An area consisting of a county or one or more contiguous counties which is officially so designated by the United States Bureau of the Budget.
(97) Submerged fill pipe - A fill pipe that extends from the top of a tank to have a maximum clearance of six inches (15.2 centimeters) from the bottom or, when applied to a tank which is loaded from the side, that has a discharge opening entirely submerged when the pipe used to withdraw liquid from the tank can no longer withdraw liquid in normal operation.
(98) Sulfur compounds - All inorganic or organic chemicals having an atom or atoms of sulfur in their chemical structure.
(99) Sulfuric acid mist/sulfuric acid - Emissions of sulfuric acid mist and sulfuric acid are considered to be the same air contaminant calculated as H2SO4 and shall include sulfuric acid liquid mist, sulfur trioxide, and sulfuric acid vapor as measured by Test Method 8 in 40 Code of Federal Regulations Part 60, Appendix A.
(100) Sweet crude oil and gas - Those crude petroleum hydrocarbons that are not "sour" as defined in this section.
(101) Total suspended particulate - Particulate matter as measured by the method described in 40 Code of Federal Regulations Part 50, Appendix B.
(102) Transfer efficiency - The amount of coating solids deposited onto the surface or a part of product divided by the total amount of coating solids delivered to the coating application system.
(103) True vapor pressure - The absolute aggregate partial vapor pressure, measured in pounds per square inch absolute, of all volatile organic compounds at the temperature of storage, handling, or processing.
(104) Unauthorized emissions - Emissions of any air contaminant except carbon dioxide, water, nitrogen, methane, ethane, noble gases, hydrogen, and oxygen which exceeds any air emission limitation in a permit, rule, or order of the commission or as authorized by TCAA, §382.0518(g).
(105) Upset event - An unplanned or unanticipated occurrence or excursion of a process or operation that results in unauthorized emissions.
(106) Utility boiler - A boiler used to produce electric power, steam, or heated or cooled air, or other gases or fluids for sale.
(107) Vapor combustor - A partially enclosed combustion device used to destroy volatile organic compounds by smokeless combustion without extracting energy in the form of process heat or steam. The combustion flame may be partially visible, but at no time does the device operate with an uncontrolled flame. 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.
(108) Vapor-mounted seal - A primary seal mounted so there is an annular space underneath the seal. The annular vapor space is bounded by the bottom of the primary seal, the tank wall, the liquid surface, and the floating roof or cover.
(109) Vent - Any duct, stack, chimney, flue, conduit, or other device used to conduct air contaminants into the atmosphere.
(110) Visible emissions - Particulate or gaseous matter which can be detected by the human eye. The radiant energy from an open flame shall not be considered a visible emission under this definition.
(111) Volatile organic compound - Any compound of carbon or mixture of carbon compounds excluding
1,1,1_trichloroethane (methyl chloroform);
methylene chloride (dichloromethane);
1,1,2_trichloro_1,2,2_trifluoroethane (CFC_113); 1,2_dichloro_1,1,2,2_tetrafluoroethane (CFC_114);
cyclic, branched, or linear completely methylated siloxanes;
1,1,1,2,3,4,4,5,5,5_decafluoropentane (HFC 43_10mee);
1_chloro_1_fluoroethane (HCFC_151a); 1,1,1,2,2,3,3,4,4_nonafluoro_4_methoxybutane;
metallic carbides or carbonates;
and perfluorocarbon compounds which fall into these classes:
(A) cyclic, branched, or linear, completely fluorinated alkanes;
(B) cyclic, branched, or linear, completely fluorinated ethers with no unsaturations;
(C) cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations; and
(D) sulfur_containing perfluorocarbons with no unsaturations and with sulfur bonds only to carbon and fluorine.
(112) Volatile organic compound (VOC) water separator - Any tank, box, sump, or other container in which any VOC, floating on or contained in water entering such tank, box, sump, or other container, is physically separated and removed from such water prior to outfall, drainage, or recovery of such water.
As adopted by TNRCC August 21, 2002, effective September 12, 2002 (G-72)
