Current through Reg. 49, No. 28; July 12, 2024
(a)
					 Applicability. The provisions in this division apply to offset lithographic
					 printing lines located in the Dallas-Fort Worth, El Paso, and
					 Houston-Galveston-Brazoria areas, as defined in §
											115.10 of
					 this title (relating to Definitions).
(b) Definitions. Unless specifically defined
					 in the Texas Clean Air Act (Texas Health and Safety Code, Chapter 382) or in
					 §§
											3.2,
					 101.1, and
					 115.10 of
					 this title (relating to Definitions), the terms in this division have the
					 meanings commonly used in the field of air pollution control. In addition, the
					 following meanings apply unless the context clearly indicates otherwise.
(1) Alcohol--Any of the hydroxyl-containing
					 organic compounds with a molecular weight equal to or less than 74.12, which
					 includes methanol, ethanol, propanol, and butanol.
(2) Alcohol substitutes--Nonalcohol additives
					 that contain volatile organic compounds and are used in the fountain solution
					 to reduce the surface tension of water or prevent ink piling.
(3) Batch--A supply of fountain solution or
					 cleaning solution that is prepared and used without alteration until completely
					 used or removed from the printing process.
(4) Cleaning solution--Liquids used to remove
					 ink and debris from the operating surfaces of the printing press and its
					 parts.
(5) Fountain solution--A
					 mixture of water, nonvolatile printing chemicals, and a liquid additive that
					 reduces the surface tension of the water so that it spreads easily across the
					 printing plate surface. The fountain solution wets the non-image areas so that
					 the ink is maintained within the image areas.
(6) Heatset--Any operation where heat is
					 required to evaporate ink oil from the printing ink.
(7) Lithography--A plane-o-graphic printing
					 process where the image and non-image areas are on the same plane of the
					 printing plate. The image and non-image areas are chemically differentiated so
					 the image area is oil receptive and the non-image area is water
					 receptive.
(8) Major printing
					 source--All offset lithographic printing lines located on a property with
					 combined uncontrolled emissions of volatile organic compounds (VOC) greater
					 than or equal to:
(A) 50 tons of VOC per
					 calendar year in the Dallas-Fort Worth area as defined in §
													115.10 of
					 this title (relating to Definitions), except Wise County;
(B) 25 tons of VOC per calendar year in the
					 Houston-Galveston-Brazoria area, as defined in §
													115.10 of
					 this title; or
(C) 100 tons of VOC
					 per calendar year in Wise County.
(9) Minor printing source--All offset
					 lithographic printing lines located on a property with combined uncontrolled
					 emissions of volatile organic compounds (VOC) less than:
(A) 50 tons of VOC per calendar year in the
					 Dallas-Fort Worth area, defined in §
													115.10 of
					 this title (relating to Definitions), except Wise County;
(B) 25 tons of VOC per calendar year in the
					 Houston-Galveston-Brazoria area, as defined in §
													115.10 of
					 this title; or
(C) 100 tons of VOC
					 per calendar year in Wise County.
(10) Non-heatset--Any operation where the
					 printing inks are set without the use of heat. For the purposes of this
					 division, ultraviolet-cured and electron beam-cured inks are considered
					 non-heatset.
(11) Offset
					 lithography--A printing process that transfers the ink film from the
					 lithographic plate to an intermediary surface (blanket) that, in turn,
					 transfers the ink film to the substrate.
(12) Volatile organic compound (VOC)
					 composite partial pressure--The sum of the partial pressures of the compounds
					 that meet the definition of VOC in §
												101.1 of
					 this title (relating to Definitions). The VOC composite partial pressure is
					 calculated as follows.
