(a) In the Beaumont-Port Arthur, Bexar County, Dallas-Fort
Worth, El Paso, and Houston-Galveston-Brazoria areas, as defined in §115.10
of this title (relating to Definitions), the control requirements
of this subsection apply. Beginning March 1, 2013, this subsection
no longer applies to flexible package printing lines in the Dallas-Fort
Worth and Houston-Galveston-Brazoria areas that are required to comply
with the requirements in subsection (c) of this section. In the Bexar
County area, the control requirements of this subsection apply to
flexographic printing lines, packaging rotogravure printing lines,
and publication rotogravure printing lines, but not flexible packaging
lines, which are required to comply with the requirements in subsection
(c) of this section.
(1) The owner or operator shall limit the volatile
organic compounds (VOC) emissions from solvent-containing ink used
on each packaging rotogravure, publication rotogravure, flexible package,
and flexographic printing line by using one of the following options.
(A) The owner or operator shall apply low solvent ink
with a volatile fraction containing 25% by volume or less of VOC solvent
and 75% by volume or more of water and exempt solvent.
(B) The owner or operator shall apply high solids solvent-borne
ink containing 60% by volume or more of nonvolatile material (minus
water and exempt solvent).
(C) The owner or operator shall operate a vapor control
system to reduce the VOC emissions from an effective capture system
by at least 90% by weight. The design and operation of the capture
system for each printing line must be consistent with good engineering
practice and must achieve, as demonstrated to the satisfaction of
the executive director, upon request, of at least the following weight
percentages:
(i) 75% for a publication rotogravure process;
(ii) 65% for a packaging rotogravure process;
(iii) 60% for a flexographic printing process; or
(iv) for a flexible package printing process, the overall
control efficiency in clause (ii) or (iii) of this subparagraph, depending
on the type of press used.
(2) A flexographic and rotogravure printing line that
becomes subject to paragraph (1) of this subsection by exceeding the
exemption limits in §115.431(a) of this title (relating to Exemptions)
is subject to the provisions of this subsection even if throughput
or emissions later fall below exemption limits unless emissions are
maintained at or below the controlled emissions level achieved while
complying with paragraph (1) of this subsection and one of the following
conditions is met.
(A) The project that caused the throughput or emission
rate to fall below the exemption limits in §115.431(a) of this
title must be authorized by a permit, permit amendment, standard permit,
or permit by rule required by Chapter 116 of this title (relating
to Control of Air Pollution by Permit for New Construction or Modification)
or Chapter 106 of this title (relating to Permits by Rule). If a permit
by rule is available for the project, the owner or operator shall
continue to comply with paragraph (1) of this subsection for 30 days
after the filing of documentation of compliance with that permit by
rule.
(B) If authorization by permit, permit amendment, standard
permit, or permit by rule is not required for the project, the owner
or operator shall provide the executive director 30 days notice of
the project in writing.
(3) Any capture efficiency testing of the capture system
must be conducted in accordance with §115.435(a) of this title
(relating to Testing Requirements).
(b) In Gregg, Nueces, and Victoria Counties, the owner
or operator shall limit the VOC emissions from solvent-containing
ink used on each packaging rotogravure, publication rotogravure, flexible
package, and flexographic printing line by using one of the following
options.
(1) The owner or operator shall apply low solvent ink
with a volatile fraction containing 25% by volume or less of VOC solvent
and 75% by volume or more of water and exempt solvent.
(2) The owner or operator shall apply high solids solvent-borne
ink containing 60% by volume or more of nonvolatile material (minus
water and exempt solvent).
(3) The owner or operator shall operate a vapor control
system to reduce the VOC emissions from an effective capture system
by at least 90% by weight. The design and operation of the capture
system for each printing line must be consistent with good engineering
practice and must achieve an overall control efficiency, as demonstrated
to the satisfaction of the executive director, upon request, of at
least the following weight percentages:
(A) 75% for a publication rotogravure process;
(B) 65% for a packaging rotogravure process;
(C) 60% for a flexographic printing process; or
(D) for a flexible package printing process, the overall
control efficiency in subparagraph (B) or (C) of this paragraph, depending
on the type of press used.
(c) Beginning March 1, 2013, in the Dallas-Fort Worth
and Houston-Galveston-Brazoria areas, and beginning January 1, 2025,
in the Bexar County area, the following control requirements apply
to each flexible package printing line.
(1) The owner or operator shall limit the VOC emissions
from coatings, as defined in §101.1 of this title (relating to
Definitions), applied on each flexible package printing line by using
one of the following options. These limits are based on the daily
weighted average, as defined in §115.430(b) of this title (relating
to Applicability and Definitions).
(A) The owner or operator shall limit the VOC emissions
from the coatings to 0.80 pound of VOC per pound of solids applied.
The VOC emission limit can be met through the use of low-VOC coatings
or a combination of coatings and the operation of a vapor control
system.
(B) The owner or operator shall limit the VOC emissions
from the coatings to 0.16 pound of VOC per pound of coating applied.
The VOC emission limit can be met through the use of low-VOC coatings
or a combination of coatings and the operation of a vapor control
system.
(C) The owner or operator shall operate a vapor control
system that achieves an overall control efficiency of at least 80%
by weight.
(2) A flexographic and rotogravure printing line that
becomes subject to paragraph (1) of this subsection by exceeding the
exemption limits in §115.431(a) of this title is subject to paragraph
(1) of this subsection even if throughput or emissions later fall
below exemption limits unless emissions are maintained at or below
the controlled emissions level achieved while complying with paragraph
(1) of this subsection and one of the following conditions is met.
(A) The project that caused the throughput or emission
rate to fall below the exemption limits in §115.431(a) of this
title must be authorized by a permit, permit amendment, standard permit,
or permit by rule required by Chapter 116 of this title or Chapter
106 of this title. If a permit by rule is available for the project,
the owner or operator shall continue to comply with paragraph (1)
of this subsection for 30 days after the filing of documentation of
compliance with that permit by rule.
(B) If authorization by permit, permit amendment, standard
permit, or permit by rule is not required for the project, the owner
or operator shall provide the executive director 30 days notice of
the project in writing.
(3) An owner or operator applying coatings in combination
with a vapor control system to meet the VOC emission limits in paragraph
(1)(A) or (B) of this subsection shall use the following equation
to determine the minimum overall control efficiency necessary to demonstrate
equivalency. Control device and capture efficiency testing must be
performed in accordance with the testing requirements in §115.435(a)
of this title.

(d) The owner or operator of a flexible package printing
process shall implement the following work practices for cleaning
materials:
(1) keep all cleaning solvents and used shop towels
in closed containers; and
(2) convey cleaning solvents from one location to another
in closed containers or pipes.
