(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).
(2) The owner or operator of a heatset offset lithographic
printing press shall operate a control device to reduce VOC emissions
from the press dryer exhaust vent by 90% by weight or maintain a maximum
dryer exhaust outlet VOC concentration of 20 parts per million by
volume (ppmv), whichever is less stringent when the press is in operation.
The dryer air pressure must be lower than the pressroom air pressure
at all times when the press is operating to ensure the dryer has a
capture efficiency of 100%.
(b) In the Bexar County, Dallas-Fort Worth and Houston-Galveston-Brazoria
areas, the following control requirements apply to the owner or operator
of a major printing source, as defined in §115.440 of this title
(relating to Applicability and Definitions), in accordance with the
appropriate compliance date specified in §115.449 of this title
(relating to Compliance Schedules).
(1) The owner or operator of an offset lithographic
printing press shall limit the VOC content of the cleaning solution,
as applied, to:
(A) 50.0% VOC or less by volume;
(B) 70.0% VOC or less by volume if the facility has
a towel handling program in place that ensures all waste ink, solvents,
and cleanup rags are stored in closed containers until removed from
the site by a licensed disposal or cleaning service; or
(C) a VOC composite partial vapor pressure less than
or equal to 10.0 millimeters of mercury at 68 degrees Fahrenheit (20
degrees Celsius) if the facility has a towel handling program in place
that ensures all waste ink, solvents, and cleanup rags are stored
in closed containers until removed from the site by a licensed disposal
or cleaning service.
(2) The owner or operator of a sheet-fed offset lithographic
printing press shall limit the VOC content of the fountain solution,
as applied, to:
(A) 5.0% alcohol or less by weight;
(B) 8.5% alcohol or less by weight if the fountain
solution is refrigerated below 60 degrees Fahrenheit (15.5 degrees
Celsius); or
(C) 3.0% alcohol substitutes or less by weight and
no alcohol in the fountain solution.
(3) The owner or operator of a non-heatset web offset
lithographic printing press shall limit the VOC content of the fountain
solution, as applied, to 3.0% alcohol substitutes or less by weight
and no alcohol in the fountain solution.
(4) The owner or operator of a heatset web offset lithographic
printing press shall limit the VOC content of the fountain solution,
as applied, to:
(A) 1.6% alcohol or less by weight;
(B) 3.0% alcohol or less by weight if the fountain
solution is refrigerated below 60 degrees Fahrenheit (15.5 degrees
Celsius); or
(C) 3.0% alcohol substitutes or less by weight and
no alcohol in the fountain solution.
(5) The owner or operator of a heatset offset lithographic
printing press shall operate a control device to reduce VOC emissions
from the press dryer exhaust vent by at least 90% by weight or maintain
a maximum dryer exhaust outlet VOC concentration of 20 ppmv or less,
whichever is less stringent when the press is in operation. The dryer
air pressure must be lower than the pressroom air pressure at all
times when the press is operating to ensure the dryer has a capture
efficiency of 100%.
(c) In the Bexar County, Dallas-Fort Worth and Houston-Galveston-Brazoria
areas, the following control requirements apply to the owner or operator
of a minor printing source, as defined in §115.440 of this title,
in accordance with the appropriate compliance date specified in §115.449.
(1) The owner or operator of an offset lithographic
printing press shall limit the VOC content of the cleaning solution,
as applied, to:
(A) 50.0% VOC or less by volume;
(B) 70.0% VOC or less by volume if the facility has
a towel handling program in place that ensures all waste ink, solvents,
and cleanup rags are stored in closed containers until removed from
the site by a licensed disposal or cleaning service; or
(C) a VOC composite partial vapor pressure less than
or equal to 10.0 millimeters of mercury at 68 degrees Fahrenheit (20
degrees Celsius) if the facility has a towel handling program in place
that ensures all waste ink, solvents, and cleanup rags are stored
in closed containers until removed from the site by a licensed disposal
or cleaning service.
(2) The owner or operator of a sheet-fed offset lithographic
printing press shall limit the VOC content of the fountain solution,

lithographic printing press shall limit the VOC content of the fountain
solution, as applied, to 5.0% alcohol substitutes or less by weight
and no alcohol in the fountain solution.
(4) The owner or operator of a heatset web offset lithographic
printing press shall limit the VOC content of the fountain solution,
as applied, to:
