Current through Reg. 49, No. 28; July 12, 2024
(a) In the El
					 Paso area as defined in §
											115.10 of
					 this title (relating to Definitions), the following control requirements apply.
(1) The owner or operator of an offset
					 lithographic printing line that uses solvent-containing ink shall limit
					 emissions of volatile organic compounds (VOC) as follows.
(A) The owner or operator of a heatset web
					 offset lithographic printing press that uses alcohol in the fountain solution
					 shall maintain total fountain solution alcohol to 5.0% or less (by volume).
					 Alternatively, a standard of 10.0% or less (by volume) alcohol may be used if
					 the fountain solution containing alcohol is refrigerated to less than 60
					 degrees Fahrenheit (15.5 degrees Celsius).
(B) The owner or operator of a non-heatset
					 web offset lithographic printing press that prints newspaper and that uses
					 alcohol in the fountain solution shall eliminate the use of alcohol in the
					 fountain solution. Nonalcohol additives or alcohol substitutes can be used to
					 accomplish the total elimination of alcohol use.
(C) The owner or operator of a non-heatset
					 web offset lithographic printing press that does not print newspaper and that
					 uses alcohol in the fountain solution shall maintain the use of alcohol at 5.0%
					 or less (by volume). Alternatively, a standard of 10.0% or less (by volume)
					 alcohol may be used if the fountain solution is refrigerated to less than 60
					 degrees Fahrenheit (15.5 degrees Celsius).
(D) The owner or operator of a sheet-fed
					 offset lithographic printing press shall maintain the use of alcohol at 10.0%
					 or less (by volume). Alternatively, a standard of 12.0% or less (by volume)
					 alcohol may be used if the fountain solution is refrigerated to less than 60
					 degrees Fahrenheit (15.5 degrees Celsius).
(E) The owner or operator of any type of
					 offset lithographic printing press shall be considered in compliance with the
					 fountain solution limitations of this paragraph if the only VOC in the fountain
					 solution are nonalcohol additives or alcohol substitutes, so that the
					 concentration of VOC in the fountain solution is 3.0% or less (by weight). The
					 fountain solution must not contain any isopropyl alcohol.
(F) The owner or operator of an offset
					 lithographic printing press shall reduce VOC emissions from cleaning solutions
					 by one of the following methods:
(i) using
					 cleaning solutions with a VOC content of 50% or less (by volume, as
					 used);
(ii) using cleaning
					 solutions with a VOC content of 70% or less (by volume, as used) and
					 incorporating a towel handling program that ensures that all waste ink,
					 solvents, and cleanup rags are stored in closed containers until removed from
					 the site by a licensed disposal/cleaning service; or
(iii) using cleaning solutions with a VOC
					 composite partial vapor pressure less than or equal to 10.0 millimeters of
					 mercury at 68 degrees Fahrenheit (20 degrees Celsius).
