 1.   The promulgated standards of performance would reduce
      hazardous air pollutants  (HAP) emissions from existing and
      new rotogravure and wide-web flexographic printing
      facilities that are major sources of HAP emissions.  Under
      Section 112 of the Clean Air Act (CAA), as amended in 1990,
      the EPA is authorized to  require the maximum degree of
      reduction in emissions of hazardous air pollutants that is
      achievable,  taking into consideration the cost of achieving
      such emission reductions, and any nonair quality health and
      environmental impacts and energy requirements.

                            1.   SUMMARY
     On March  14,  1995, the EPA proposed national emission
 standards  for  hazardous air pollutants  (NESHAP) for rotogravure
 and wide-web flexographic printing  (60  FR 13664) under authority
 of Section 112 of  the amended CAA.  Public comments were
 requested  on the proposal in the Federal Register.  One hundred
 seventeen  commenters, composed  of State and local air pollution
 control agencies;  trade associations for printers; ink
 manufacturers  and  control equipment manufacturers; printers; ink
 manufacturers; and citizens responded to the request.
     The comments  that were submitted and the responses to those
 comments are summarized in  this document.  The summary of
 comments and responses serves as the basis for the revisions made
 to the standards between proposal and promulgation.
 1.1 SUMMARY OF CHANGES MADE SINCE PROPOSAL
     Several changes have been made since the proposal of these
 standards.  A discussion of these changes is provided in the
 preamble to the final rule.   A summary of the major changes is
 presented  below.
 1.1.1 Incidental Printing and Ancillary Printing Equipment
     The final standard includes simplified requirements and does
 not mandate emission controls for incidental printers.
 Incidental printers are a subgroup of product and packaging
 rotogravure or wide-web flexographic printing affected sources at
 facilities that are major sources of HAP.   Affected sources
within this subgroup are those which meet a monthly threshold in
either materials applied or organic HAP applied on product and
packaging  rotogravure and wide-web flexographic printing presses.
Such affected sources would be subject only to initial
notification requirements and recordkeeping requirements to show
that one of the thresholds is met every month.   If,  in any month,
such an affected source meets neither of the thresholds,  then the
affected source would become subject to all relevant requirements
of the final standard and would no longer qualify for inclusion
                                1-1

-------
in the subgroup even if, in subsequent months, the affected
source did meet either of the thresholds.
     The  final standard also permits the owner or operator of a
product and packaging rotogravure or wide-web flexographic
printing  affected source to choose to exclude ancillary printing
equipment from the affected source.  This equipment is used
primarily for coating, laminating, or other operations besides
product and packaging rotogravure and wide-web flexographic
printing.  Presses on which five weight-percent or less of the
total material applied each month is applied by rotogravure or
wide-web  flexographic print stations would be subject only to a
simplified recordkeeping requirement.  The EPA believes it is
appropriate to provide the owner or operator with the option not
to subject these presses to the HAP emission limitations for
product and packaging and wide-web flexographic printing in
§63.825 because the work being done on the rotogravure and wide-
web flexographic print stations on these presses is ancillary to
the work  being done on other work stations (i.e.,  coating
stations)  on these presses.   The EPA is separately establishing
maximum achievable control technology (MACT)  for other source
categories,  such as the paper and other web coating source
category  and the metal coil  coating source category,  which may be
more appropriate for this type of equipment.   Ancillary printing
equipment, if excluded from this standard,  will be subject to the
appropriate source category standard when such a standard is
issued.
1.1.2  Research and Laboratory Equipment
     All  research and laboratory equipment has been excluded from
the final standard whether or not it is collocated with
production facilities.
1.1.3  Addition of Presses to Existing Affected Sources
     Addition of presses to existing affected sources will
subject the affected source  to the compliance deadline for new
sources if the additional press or presses constitutes a
reconstruction of the source.   Additions,  replacements, and
                                1-2

-------
modifications  to  existing  sources which do not meet the
 i
definition  of  reconstruction  do not alter the compliance
deadline.
1.1.4  Affected Source  for Product and Packaging Rotogravure and
Wide-web  Flexographic Printing Facilities
     The  final standard considers all product and packaging
rotogravure and wide-web flexographic printing equipment at a
given facility as a  single affected source.  Compliance with
reporting and recordkeeping requirements for a single affected
source will be less  burdensome than compliance on a press-by-
press basis.  In  addition, sources may achieve the required
emissions reductions through  affected source-wide limitation of
emissions,  including controlled and uncontrolled presses.  This
will allow  sources to comply  in the most cost-effective way and
will not  require expensive control equipment for small presses
which emit  relatively small amounts of .organic HAP if equivalent
emissions reductions can be achieved elsewhere within the
affected  source.
1.1.5  Organic HAP Analysis Methods
     The  final standard adopts Method 311,  as revised and
promulgated with the wood  furniture NESHAP,  for organic HAP
analysis.   Printers  and ink manufacturers have the option of
relying on  formulation data if the data meet specified criteria.
In the event of any  discrepancy between formulation data and the
results of  Method 311,  the results of Method 311 shall be
presumed to govern for all compliance purposes.
     In addition,  the printer may determine the volatile matter
content of  the material and use this value for the organic HAP
content for all compliance purposes.   This option may be useful
if organic HAP makes up all or substantially all of the volatile
matter in an ink or  other material.
1.1.6  Volatile Matter Analysis Methods
     The final standard allows printers and ink manufacturers the
option of relying on formulation data for volatile matter and
solids contents,  in  lieu of EPA Methods 24  and 24A.   In the event
                                1-3

-------
of any discrepancy between formulation data and the results of
the EPA test methods, the test methods shall be presumed to
govern for all compliance purposes.
1.1-7  Compliance Monitoring for Catalytic Oxidizers
     The final standard requires owners or operators using a
catalytic oxidizer and monitoring an operating parameter to
ensure compliance with the standard to monitor the temperature
immediately upstream of the catalyst bed.  The requirement to
monitor the temperature downstream of the catalyst bed has been
eliminated.  Since the operating parameters are established
during a test under normal operating conditions,  a downstream
temperature monitoring parameter might be impossible to meet
during periods when organic loading to the oxidizer was lower
than normal.   This might have led to exceedances which were not
indicative of improper operating conditions or excessive
emissions.
1.1.8  Additional Compliance Options for Product and Packaging
Rotogravure and Wide-web Flexographic Printing Affected Sources
     In order to make the compliance options for low organic HAP
materials based on organic HAP content and solids applied
consistent with the definition of affected source,  additional
means of demonstrating compliance have been added to the final
rule.  Affected sources may demonstrate that each material
applied meets either of the organic HAP thresholds,  or that all
materials on average meet either of the organic HAP thresholds,
or that the organic HAP emitted is less than the organic HAP
allowed taking these thresholds into account.   In addition,
emissions from controlled and uncontrolled presses are aggregated
to determine compliance with an organic HAP emission standard
applicable to the entire affected source.
1.1.9 Capture Efficiency Protocols and Test Methods
     The final rule allows the use of alternate capture
efficiency protocols and test methods which satisfy the criteria
of either the Data Quality Objective or Lower Confidence Limit
approaches.  An appendix describing these approaches has been
                                1-4

-------
 added to the final rule.   Additional  information  on  alternate
 capture  efficiency protocols  and test methods  is  available  in
 Guidelines for Determining Capture Efficiency. January  1995.
 This  document is  attached  to  Item No.  II-B-3 in the  project
 docket.
 1.1.10 Transition from Area Source to Major Source Status
      A provision  has  been  added  to the final rule by which
 owners or operators that have used the provisions of
 §63.820(a) (2)  to  establish the facility as an  area source may
 reestablish the facility as a major source.  Such a  source  must
 comply with its HAP usage  commitments  until it meets all
 requirements for  major sources.
 1.1.11 Definition of  "Month"
      The  definition of "month" in the  final rule  has been changed
 to include  prespecified periods  of 28  to 35 days.
 1.1.12 Alternatives to Vent Stream FlowrRate Monitoring
      The  final regulation  includes alternatives to the vent
 stream flow rate  measurement  requirement.
      Owners or operators of product and packaging rotogravure or
 wide-web  flexographic  presses with intermittently-controllable
 work  stations may,  as  alternatives to  measuring vent stream flow
 rate,   install flow  indicators on  the bypass lines, secure bypass
 line  valves with  locking mechanisms or car seals,  continuously
 monitor bypass valve position or  equip the press with an
 interlock preventing operation when the control device is
 bypassed.   Sampling lines  for gas analyzers and relief valves
 needed for  safety purposes are not considered bypass lines for
 the purposes of these provisions.  Presses that do not have any
 intermittently-controllable work  stations are not subject to
 these provisions.
 1.1.13 Extension of Deadline for  Initial Notification
     The final rule overrides the General Provisions and requires
 initial notification for existing sources no later than one year
before the  compliance date.  This will allow existing sources two
years  from  the date of promulgation of this standard.  The EPA
                                1-5

-------
believes that this will provide adequate notice to ensure
compliance.
1.1.14 Provisions for Optional Inclusion of Stand-alone Coating
Equipment
     The final rule provides a mechanism by which product and
packaging rotogravure and wide-web flexographic printers may
include stand-alone coating equipment in their affected source.
This inclusion is optional and subject to certain eligibility
criteria.  Coating equipment may be covered by standards for
other source categories (e.g., Paper and Other Web Coating) which
will be promulgated in the future.  In order to avoid the
additional effort required to comply with two (or more) separate
MACT standards,  owners or operators of printing affected sources
may choose to subject this equipment to regulation under the
printing and publishing standard.
     Stand-alone coating equipment is eligible for inclusion if
(1) it coats the same substrate as a rotogravure or wide-web
flexographic press included in the affected source, or (2) it
applies a solids-containing material in common with a rotogravure
or wide-web flexographic press included in the affected source,
or, (3) it shares a control device with a rotogravure or wide-web
flexographic press included in the affected source.  In order to
take advantage of this provision, all eligible stand-alone
coating equipment within the facility must be included and no
product or packaging rotogravure or wide-web flexographic presses
may be excluded from the affected source using the mechanism in
§63.821(a)  (2) (ii) .
1.2 SUMMARY OF IMPACTS OF PROMULGATED ACTION
     The final rule will reduce nationwide emissions of HAP by
approximately 6700 megagrams per year (mg/yr) (7400 tons per year
(tpy)).  This will result from a reduction of approximately
4,750 mg/yr (5,220 tpy)  from publication rotogravure facilities
and an additional 1,940 mg/yr (2,140 tpy) from product and
package rotogravure and wide-web flexographic printers.
Substantial reductions in emissions of volatile organic compounds
                                1-6

-------
 (VOC) are also expected as a result of this rule.  The VOC
 reductions may be slightly greater than the HAP reductions  if
 affected sources convert from HAP containing solvent-based
 materials to waterborne or radiation cured materials.
 Alternately, the VOC reductions may be slightly less than the HAP
 reductions if affected sources convert from HAP containing
 solvent-based materials to reduced HAP solvent-based materials in
 lieu of upgrading capture and control systems.
     The nationwide annual costs  (including capital recovery) of
 the final rule are estimated at $40 million per year. These costs
 include $21 million per year for publication rotogravure printers
 and $19 million per year for package and product rotogravure and
 wide-web flexographic printers.  Cost estimates for publication
 rotogravure printers remain unchanged from the proposed rule.
 Estimated costs for package and product rotogravure and wide-web
 flexographic printers are slightly less, than those for the
 proposed rule due to reductions in cost as a result of facility-
 wide definition of affected source.   The proposed rule was
 determined not to have a significant economic impact.  No firms
 or facilities were found to be at risk of closure as a result of
 the standards and there was not a significant economic impact on
 a substantial number of small entities.   Because compliance costs
 and reporting and recordkeeping burdens have been reduced in the
 final rule,  the economic impact has not increased and remains
 insignificant.
     No significant secondary environmental impacts are expected
 to occur as a result of this rule.  The rule encourages
 conversion of HAP based ink systems to ink systems based on non-
HAP substitutes.   To the extent that printers adopt waterborne
 ink systems,  some reduction in the production of Resource
 Conservation and Recovery Act regulated hazardous waste,  and some
 increase in discharges of wastewater to publicly owned treatment
plants may occur.
     A net increase in consumption of electricity is expected to
occur as a result of increased fan horsepower requirements in
                                1-7

-------
systems which are retrofit to improve capture efficiency.
Individual facilities that choose to comply through partial or
complete elimination of solvent borne ink systems in favor of
waterborne or radiation cure ink systems will use less
electricity.  Because it is impossible to predict the extent to
which various compliance strategies (i.e.,  improved capture and
control, conversion to non-HAP solvent-borne materials,  or
conversion to waterborne or radiation cure materials), the net
impact of the rule on electricity consumption has not been
estimated.

 2.1   SYNTHETIC AREA SOURCE  MECHANISM
      Comment:  A  number  of  comments were received suggesting
 simplified  mechanisms  for establishing synthetic area source
 status.   Three commenters recommended strategies involving  state
 operating permits.   Commenter  IV-D-36 suggested accepting
 emissions limitations  under "Federally Exempt State Permits."
 Commenter IV-D-63 suggested grandfathering facilities which
 presently have state operating permits which incorporate HAP
 emission  limits.  Commenters IV-D-49 and IV-D-63 suggested
 allowing  case-by-case  operating restrictions within State
 permits.
      Seven  commenters  suggested specific mechanisms to establish
 area  source status.  Commenter IV-D-14 suggested -that sources
 determine emissions  using initial capture and control device test
 data  in conjunction  with actual ink usage rates and HAP contents.
 If oxidizers were used, continuous temperature monitoring would
 be required.  The sources would maintain monthly records of
 calculated  emission  rates and  provide an annual self-certified
 report.   If physical limitations prevented a source from emitting
 at threshold levels  (presumably a source so small or so slow that
 it could  never use threshold levels of HAP)  then a onetime
 certification would  suffice.   Commenter IV-D-53 suggested the use
 of capture  and control device  test data and formulation data to
 establish that emissions were  90 percent or less of the 10/25
 threshold.  Sources would be required to maintain records to
 demonstrate this on a twelve month rolling average basis.
 Commenter IV-D-98 suggested having the source report actual
 emissions (taking into account documented capture and control
 efficiencies)  to the permitting authority on a quarterly basis.
     Commenter IV-D-80 suggested calculating actual emissions
based on overall control efficiency testing and then requiring
monitoring,  recordkeeping,  and reporting only with respect to
 conformity with an operating and maintenance plan for the control
equipment.
                               2-9

-------
     Commenter  IV-D-39 suggested that major sources that
establish the existence of control devices which limit emissions
to below threshold amounts be treated in accordance with the
John Seitz memoranda of 1/25/95 and 5/16/95; and that these
sources not be  required to maintain a Title V permit.
     Commenter  IV-D-79 suggested a simplified cutoff based on
quantity of materials used (e.g., 250 gallons per month, as in
wood furniture); the commitment procedure could take the form of
a signed statement submitted before the final compliance date.
Very small facilities (2 tons/5 tons)  could demonstrate
compliance on request of the regulatory authority without any
commitment.  Commenter IV-D-18 suggested using the Superfund
Amendments and Reorganization Act (SARA) 313 annual recordkeeping
and reporting to establish emissions below the 10/25 threshold.
     Two commenters (IV-D-39 and IV-D-53)  suggested excluding
area sources from a requirement for a Part 70 permit.
Commenter IV-D-53 requested explicit language that §63.821(d) of
the proposed rule applies only to major sources.
     Response:  The synthetic area source mechanism in §63.820
has been retained.  This is not intended to preclude the use of
other mechanisms based on Federally enforceable limitations on
potential-to-emit.  These mechanisms are described in the
response included in section 2.2 below.   As described below,
major source status is not determined by actual HAP emissions or
actual HAP use.  Any limitations on potential-to-emit must be
physical (e.g., size,  capacity,  speed,  materials compatibility)
or Federally enforceable commitments (or certain State-
enforceable commitments which are practically effective).
Additional information is provided in the EPA's "Interim Policy
of Federal Enforceability of Limitations on Potential to Emit"
(Docket Item IV-B-2).
     Provisions by which sources can establish area source status
based on the use of control devices have not been added to the
rule.  Major source status is determined by facility-wide
potential-to-emit.  The use of control equipment to control
                              2-10

-------
emissions  from affected  sources under this rule might not ensure
area source  status because of potential emissions  from collocated
affected sources subject to other source categories.  In making
and demonstrating compliance with area source commitments outside
of this rule for facilities with controlled printing presses, the
procedures in this rule  for determining HAP content, capture
efficiency,  control device efficiency, monitoring  and
recordkeeping may be useful in limiting the potential to emit
from the controlled printing presses.
     Simplified requirements have been added to the final
standard for incidental printers.  These are major sources which
operate product and packaging and wide-web flexographic printing
presses that apply relatively small amounts of material or apply
relatively small quantities of HAP.  Sources which apply no more
than 500 kilograms (kg) per month of materials on product and
packaging rotogravure and wide-web flexographic printing presses,
or no more than 400 kg per month of organic HAP on product and
packaging rotogravure and wide-web flexographic printing presses
are subject  only to greatly simplified recordkeeping
requirements.
     In addition,  owners or operators of ancillary printing
equipment may exclude this equipment from the affected source.
Ancillary printing equipment is equipment which is used primarily
for coating,  laminating,  or printing by processes other than
product and packaging rotogravure and wide-web flexographic
printing.   Presses on which five weight-percent or less of the
total material applied each month is applied by rotogravure or
wide-web flexographic print stations would be subject only to a
simplified recordkeeping requirement.
     The requirement to apply for and obtain a Part 70 permit is
not exclusively based on Title III (HAP).   Other pollutants, at
levels which vary by location,  and requirements of State
implementation plans also affect Part 70 permit requirements.
The area source provisions within the rule do not obligate the
source to obtain a Part 70 permit,  nor do they exempt the source
                              2-11

-------
from other requirements to which it is subject.  Consistent with
the EPA's December 1995 proposal to amend the NESHAP for Chromium
Electroplating, nonmajor sources are not required to obtain
Title V operating permits.
2.2   DEFINITION OF MAJOR SOURCE
     Comment:  Seven commenters (IV-D-1,  IV-D-15, IV-D-36,
IV-D-51, IV-D-53, IV-D-63, IV-D-79, and IV-D-84) suggested basing
major source status on HAP emissions as opposed to HAP use.  Five
of the seven (IV-D-1, IV-D-36, IV-D-53, IV-D-63, and IV-D-84)
further suggested that major source status should be based on
organic HAP use, as inorganic HAP are not regulated under the
proposed standard.  Commenter IV-D-36 specifically recommended
exclusion of organic HAP which is not emitted (such as
dibutylphthalate) from the determination of major source status.
     Commenters IV-D-38 and IV-D-51 suggested exempting small
printing operations located at facilities that are major sources
as a result of other operations.   Commenter IV-D-51 suggested
establishing a de minimis quantity of HAP use for these
operations, or alternately allowing the source to commit to a
5/10 threshold based on HAP use and confirm this by maintaining
material safety data sheets (MSDS)  and records of materials used.
     Response:   Major source status is determined based on
"potential-to-emit" as defined in the General Provisions, §63.2,
as opposed to actual emissions or HAP usage for any particular
year.   Potential-to-emit means the maximum capacity of a
stationary source to emit a pollutant under its physical and
operational design. Any physical  or operational limitation on the
capacity of the stationary source to emit a pollutant,  including
air pollution control equipment and restrictions on hours of
operation or on the type or amount of material combusted, stored
or processed, shall be treated as part of its design if the
limitation or the effect it would have on emissions is Federally
enforceable.
     Federally enforceable limits on potential-to-emit can be
obtained through new source review permits, permits issued under
                               2-12

-------
 State operating permit programs adopted in State implementation
 p*lans and approved by the EPA (extended to HAP) ,  Title V
 operating permits, State implementation plan limits for
 individual sources,  Section 112(1)  State HAP programs,  or State-
 created protocols included in a Section 112(1)  provision.  Other
 mechanisms may also be available.
      Nonvolatile materials,  including many metallic compounds,
 may not be capable of being emitted as air pollutants.   Use of
 materials which have no potential  for emission  to the  air do not
 affect major source status.   However,  the definition of
 "hazardous air pollutant" in §112(b)  of the CAA (including all
 inorganic HAP)  is the basis  for making major source
"determinations if the facility has  the potential  to emit such
 pollutants (even if they are not controlled by  this standard).
      The CAA defines "major  source"  to mean "any  stationary
 source or group of stationary sources  [emphasis added]  located
 within a contiguous  area and under  common control that  emits or
 has the potential to emit considering  controls, in the  aggregate.
 [emphasis added]  10  tpy or more  of  any hazardous  air pollutant  or
 25  tpy or more  of any combination of hazardous air pollutants."
 The EPA interprets this to allow aggregation of sources across
 source categories at a facility  in  determining major source
 status.
      Simplified provisions have  been added to the final rule for
 incidental printers.   These  are  small  printing operations located
 at  facilities which  are major sources  principally as a  result of
 other operations.  These sources are subject only to simplified
 recordkeeping requirements.
 2.3   TRANSITION FROM AREA SOURCE TO MAJOR SOURCE
      Comment:   Commenter IV-D-15 requested that a provision
 allowing a transition period for a newly  designated major source
 to  come  into compliance be incorporated in the rule.  The
 proposal makes  no allowance  for  a source  to make  this transition
 without  being in  violation of  the standard.
                               2-13

-------
     Response:  The owner or operator of an area source intending
to increase the capacity of the facility to the extent that it
would become a major source is required to apply for and obtain a
Title V permit.  The owner or operator of an area source seeking
to remove a provision limiting potential-to-emit from the
source's Title V permit must apply for and obtain a permit
modification.  Any new area source that becomes a major affected
source must comply with the standard upon becoming a major
source.  Any existing area source that becomes a major affected
source must comply with the standard by the existing source
compliance date or upon becoming a major source, whichever is
later.
     A provision has been added to the final rule in
§63.820(a)(6) which provides a mechanism for owners or operators
that have used the provisions of §63.820(a)(2)  to establish the
facility as an area source to reestablish the facility as a major
source.  Such a source must continue to comply with its HAP usage
commitments until it meets all requirements for major sources.
2.4  ONCE IN/ALWAYS IN
     Comment:  Commenters IV-D-14 and IV-D-15 stated that this
policy eliminates an incentive for companies to reduce HAP
emissions.  Three commenters (IV-D-14,  IV-D-49 and IV-D-84)
requested the inclusion of a provision for major sources to alter
their operations and become area sources.   Commenter IV-D-14
recommend a mechanism for attaining synthetic area source status
through documentation of monthly records of emission rates and an
annual report.   If physical modifications are made to eliminate
the possibility of major source level emissions, a onetime
certification is suggested.  Commenters IV-D-49 and IV-D-84
request some mechanism to attain synthetic area source status
after eliminating HAP use or reducing HAP use below a de minimis
level.
     Commenters IV-D-36 and IV-D-53 request a provision for
retaining area source status after a violation of the commitment.
                               2-14

-------
 Commenter  IV-D-84  suggested  an appeal process whereby facilities
 with onetime  exceedances  can maintain area source status.
     Response:  The  EPA believes that the "once in, always  in"
 policy  follows most  naturally from the language and structure of
 the CAA.   In  many  cases,  application of maximum achievable
 control technology (MACT) will reduce a major emitter's emissions
 to levels  substantially below the major source thresholds.
 Without a  "once in,  always in" policy, these facilities could
 "backslide" from MACT control levels by obtaining pc tential-to-
 emit limits,  escaping applicability of the MACT standard, and
 increasing emissions to the  major source threshold  (10/25 tpy).
 Thus, the  maximum  achievable emissions reductions that Congress
 mandated for  major sources would not be achieved.  A "once  in,
 always in" policy  ensures that the MACT emission reductions are
 permanent, and that the health and environmental protection
 provided by MACT standards is not undermined.
     This  issue was addressed in a May 16, 1995 memo "Potential
 to Emit for MACT Standards--Guidance on Timing Issues" from
 John Seitz, Director of the Office of Air Quality Planning and
 Standards, to the  directors of Regions I through X
 (Docket Item  IV-B-2), and further discussed in the Background
 Information Document (BID) for the promulgated NESHAP for Wood
 Furniture Manufacturing Operations (EPA-453/R-95-018b).
 2.5  RESEARCH AND  LABORATORY OPERATIONS
     Comment -.   Eight comments were received requesting varying
degrees of exemption for research and laboratory equipment. 'Five
commenters (IV-D-15, IV-D-36, IV-D-61,  IV-D-63,  IV-D-80,  and
 IV-D-84) suggested exempting all  research and development
activities from the standard.  Commenter IV-D-80 stated that the
purpose and operation of a research press is independent of its
location.   Commenter IV-D-63 suggested exempting research and
development activities which are  collocated with production;
these are the  only research and development activities expected
to be affected by the proposed rule.   Commenter IV-D-61 suggested
                              2-15

-------
exempting all research and laboratory operations and covering
these operations with a separate standard.
     Commer.ter IV-D-1 suggested exempting laboratories collocated
at production facilities if they are located in separate
buildings.  The same individual recommended in a separate comment
(IV-D-17) exempting all research and laboratory facilities whose
primary purpose is research and development of new processes and
products.
     Two comments were received on research work conducted on
production presses.  Commenter IV-D-63 suggested exempting
research and development on production presses if it was done in
non-marketable quantities.   Commenter IV-D-82 suggested that
trial runs of less than production quantity (presumably conducted
on production equipment)  should be exempt and that a de minimis
in terms of press size,  hours of operation,  or maximum emissions
should be specified.
     Response:  The final rule excludes research and laboratory
equipment.   As the commenter suggested,  in order to regulate
research and laboratory equipment,  it would be necessary to
develop a separate source category as directed by
Section 112(c)(7)  of the CAA to assure equitable treatment of
such equipment.   Furthermore,  the EPA believes that many of the
types of emission points associated with research and laboratory
equipment (such as laboratory bench-scale equipment)  may not be
feasibly controlled using the same control devices as are used
for production equipment because they may be small, intermittent,
remote from production equipment or incompatible with materials
used in the production process.
2.6  NEW SOURCE MACT
     Comment:   One commenter IV-D-49 suggested that the EPA
consider establishing separate new source MACT standards.
     Response:  The EPA believes that the standard for existing
publication rotogravure facilities, 92 percent overall control on
a facility-wide basis to be achieved each and every month, will
require an efficient capture system and a state-of-the-art
                               2-16

-------
 control device.   This level of control is the MACT floor for both
 existing and new sources.  There is no distinct identifiable
 technology available to new sources that would allow them to
 achieve a more stringent standard.
      The EPA believes that the overall efficiency standard for
 existing package and product facilities,  95 percent overall
 control on a facility wide basis to be demonstrated under
 performance test conditions,  will require an efficient  capture
 system and a state-of-the-art control device.   This level of
 control is the MACT floor for both existing and new sources.
 There is no distinct identifiable technology available  to new
 sources that would allow them to achieve a more stringent
-standard.   Because of the wide variation in performance
 requirements of  printed substrates,  there is no assurance that
 all  new facilities would be able to meet a more stringent
 standard through the use of low-HAP materials.
 2.7   AFFECTED SOURCE AT PUBLICATION FACILITIES
      Comment:   Commenter IV-D-15 suggested explicitly clarifying
 that the affected source for the publication rotogravure standard
 is the entire  facility (not individual presses  or operations)  and
 that the standard be restricted to  gravure related operations
 using organic  HAP.
      Response:   The definition of the affected  source in
 §63.821(a)(1)  includes all rotogravure presses  and all  affiliated
 equipment  within a facility.   Plating of  rotogravure  cylinders is
 covered by a separate NESHAP  in subpart N,  and  is not regula'ted
 under this standard.
 2.8   AFFECTED  SOURCE AT PRODUCT AND PACKAGING ROTOGRAVURE AND
 WIDE-WEB FLEXOGRAPHIC PRINTING FACILITIES
      Comment:  Four commenters (IV-D-36,  IV-D-51,  IV-D-53,  and
 IV-D-88)  suggested allowing compliance based on the entire
 facility rather  than line-by-line.   Commenter IV-D-36 suggested
 this only  with regard to averaging  materials to meet  the low-HAP
 threshold,  and stated that it  would cut recordkeeping expenses
                               2-17

-------
from $250,000 per year to $20,000.  Commenter IV-D-53 also stated
that this would reduce recordkeeping expenses.
     Eight commenters (IV-D-1, IV-D-15, IV-D-36, IV-D-51,
IV-D-53, IV-D-63, IV-D-82, IV-D-84) suggested allowing grouping
and averaging for all presses controlled by any common control
device rather than only solvent recovery systems.
     Two commenters  (IV-D-17 and IV-D-36)  suggested allowing
individual stations or any groups of stations on the same press
to comply on an individual or group basis with any standard.
Various parts of the same press could comply on the basis of the
low-HAP threshold, the low solids threshold or the HAP emissions
threshold.  Station by station inventories of materials used
would be maintained.
     Commenter IV-D-51 suggested relaxing the qualifications for
group compliance applicable to groups of presses controlled by a
common solvent recovery system.  The Commenter suggested dropping
the requirement that common solvent recovery systems be used only
for control of printing operations so as not to penalize
facilities that have tightened up their control systems by tying
in other sources of HAP.
     Commenter IV-D-38 suggested including cylinder and parts
cleaners, ink and solvent mixing, and solvent recovery equipment
at product and packaging facilities to make it consistent with
the operations covered at publication rotogravure  facilities.
     Five commenters requested restrictions on the applicability
of the standard and one commenter requested clarifying the
applicability.  Two commenters (IV-D-36 and IV-D-51)  suggest
restricting applicability to sources using organic HAP.
Commenter IV-D-54 suggested adding language to §63.821 exempting
sources that do not use HAP even if they are collocated with
other non-printing operations that are major sources.
Commenter 81 suggested excluding rotogravure equipment located at
facilities with non-printing standard industrial classification
(SIC) codes, such as chemical plants, and regulating them when
the appropriate chemical process plant MACT is issued.
                               2-18

-------
 Commenter  IV-D-82  requested an  exemption  for  (undefined) small
 presses  collocated with  large presses  as  these will be expensive
 to control  and will yield  little emission reduction.
 Commenter  IV-D-39  requested explicit clarification that presses
 collocated  at major sources are affected  sources under the
 standard.
     Commenter IV-D-63 suggested correcting the error in
 §63.825(b)  of the  proposed rule to include flexographic presses.
 This was inadvertently omitted.
     Response:  The final  rule  defines the affected source to
 include all of the packaging and product  rotogravure and wide-web
 flexographic printing presses rather than individual presses.
 This will reduce recordkeeping, reporting, compliance
 demonstration, and enforcement  costs.  All presses, including
 uncontrolled presses and controlled presses regardless of whether
 they share a common control  system are included.  The facility-
                                       *
 wide affected source definition is not expected to affect the
 overall emissions  from a facility but it  will eliminate the need
 to run particular  printing  jobs on particular presses as part of
 a facility's compliance strategy.  Station-by-station compliance,
 grouping of stations which  are part of one or more presses, and
 press-by-press compliance are not permitted in the final rule
 because facility-wide compliance encompasses these options and is
 more easily and more reliably demonstrated.   In addition to
 reducing recordkeeping costs, this will reduce the labor
 associated with enforcement.  Facilities which apply a
 combination of materials, all of which meet either the low-
HAP/solids or the  low-HAP/material thresholds, can comply with
 the rule without dedicating particular stations to specific types
of materials.   Facility-wide definition of affected source will
 remove the incentive for awkward and suboptimal scheduling of
 jobs and equipment to achieve press-by-press compliance.   In
addition, facilities will have an incentive to decrease HAP use
where possible (beyond the emissions threshold for a particular
job,  press,  or type of application)  to achieve an emission
                              2-19

-------
reduction that can be used to offset emissions in areas where
emission reduction is more expensive.
     The final standard includes provisions by which an owner or
operator of stand-alone coating equipment which is functionally
related to printing equipment, may choose, under some
circumstances, to include this equipment in an affected source.
To be eligible for inclusion, stand-alone coating equipment must
share a common control device with a rotogravure or wide-web
flexographic press included in the affected source,  or coat a
substrate previously or subsequently printed by a rotogravure or
wide-web flexographic press included in the affected source, or
apply a solids-containing material which is also applied by a
rotogravure or wide-web flexographic press included in the
affected source.  Equipment which is not functionally related to
product and packaging rotogravure printing or wide-web
flexographic printing presses is more appropriately regulated
under a different standard (e.g., Paper and Other Web Coating).
     The EPA does not have sufficient data to determine MACT for
cylinder and parts washers, proof presses, and ink and solvent
mixing and storage equipment affiliated with presses at product
and packaging rotogravure and wide-web flexographic printing
facilities.  The extremely diverse nature of this segment of the
printing industry (equipment type, material type, substrate type,
and product or package produced)  complicates the determination of
achievable control.   The database for publication rotogravure
facilities provided material balances over all printing rela'ted
equipment.
     The rule applies to affected sources located at major
sources of HAP.  Recordkeeping for facilities that use no organic
HAP on their product and packaging rotogravure and wide-web
flexographic printing presses requires minimal labor and is
essential to ensure that the facilities are in fact using no HAP
and that the facilities maintain information from testing or from
raw material suppliers to establish this fact.  Such facilities
may use the provision in §63.821(b)  of the final rule.
                              2-20

-------
     The  EPA does not believe that it can determine what
 facilities  operate printing presses using only SIC codes.
 Converters  and product printers generally use an SIC code
 specific  for the type of product or package that they produce.
 MACT for  controlling organic HAP emissions from product and
 packaging rotogravure and wide-web flexographic presses is
 independent of whether or not the press or presses are collocated
 with a chemical plant or other potential source of HAP.
     The  final standard includes a facility-wide definition of
 affected  source which will allow owners or operators to achieve
 facility-wide organic HAP emission reductions through
 installation or upgrading of capture or control equipment or by
 reducing  the organic HAP content of materials used on whatever
 press or  presses that this can be most economically implemented.
     Section 63.821(a)(2)  of the final rule specifies that all
 product and packaging rotogravure or wide-web flexographic
 presses at a facility are subject to the standard (except for
 proof presses).   The final rule includes wide-web flexographic
 presses along with product and packaging rotogravure presses in
 all requirements of the standard.   Although this applicability
 was discussed in the preamble to the proposed rule,  it was
 inadvertently omitted from the proposed standard.
 2.9  DEFINITIONS
     Comment:   Various  comments were received suggesting
 additional or revised definitions.   In some cases the definitions
which were suggested were  part of suggestions for alternate
 regulations or  clarifications.
     Commenters  IV-D-1  and IV-D-63  suggested separate definitions
of "HAP used for publication rotogravure" and "HAP used for
 Package/Product  rotogravure and flexography" with HAP used for
package/product  rotogravure and flexography defined as equivalent
 to "HAP applied".   Commenter IV-D-53 suggested defining "HAP
used" to apply  only to  publication  rotogravure.
                              2-21

-------
     Commenter IV-D-15 suggested expanding the definition of
month to include  (unspecified) "months" other than calendar
months or 28 or 35 days.
     Commenter IV-D-15 suggested defining organic volatile matter
as VOC, and recommended new definitions for "overall equivalent
volatile organic HAP control efficiency" and "overall organic
volatile matter recovery" to reflect the combination
substitution/control efficiency and recovered HAP plus non-HAP
solvent.  Commenter IV-D-15 also recommended adding definitions
for "facility" and "source."
     Three comments were received suggesting definition of the
term "emission unit" as part of suggested changes to the
designation of affected sources.   Commenters IV-D-17 and IV-D-36
recommend defining an emission unit as a station or group of
stations on a press.  Commenter IV-D-63 suggested defining
emission unit as a stand alone press,  a press within a group of
commonly controlled presses or an inboard or outboard station on
a press.
     Commenter IV-D-17 recommended that "HAP control efficiency"
be defined and the definition include a statement that it is not
expected to be different than VOC control efficiency.
     Commenters IV-D-36 and IV-D-63 suggest defining "HAP
emitted" to exclude materials in ink such as phthalates which are
not emitted.
     Commenter IV-D-49 suggested changing the capture efficiency
definition to provide that HAP must reach the inlet of the
control device, not just be directed towards it.
     Commenter IV-D-49 suggested including a de minimis in the
definition of research and development.
     Commenter IV-D-54 recommended defining rotogravure printing
to exclude single uniform coatings over the length and width of
the substrate.  Commenter IV-D-61 recommended including a
definition of "off-line rotogravure coating".
     Response:  The definitions of HAP applied and HAP used have
been clarified.  The standards including the equations used to
                               2-22

-------
demonstrate  compliance and the definitions of the variables used
in those  equations are expressed in terms of "HAP used" for
publication  rotogravure and  "HAP applied" for product and package
rotogravure  and wide-web flexographic printing.
     The  definition of "month" in the final rule has been changed
to include prespecified periods of 28 to 35 days.
     Organic volatile matter encompasses a wider range of
materials than VOC which excludes exempt solvents and is subject
to change in the future.  The standard has been written based on
organic volatile matter.  The compliance procedures, and the
equations for demonstrating compliance are consistent with the
definitions  of the variables used in the equations.  Affected
source is defined for the purposes of this standard in §63.821.
A definition of facility has been added.
     The  standard for product and packaging rotogravure and wide-
web flexographic printing includes a revised description of
affected  source to include all product and packaging rotogravure
and wide-web flexographic presses at the facility (with certain
exceptions).   Facility-wide definition of affected source
provides  flexibility in choosing how to comply with the rule.
The final standard does not provide for compliance on the basis
of emission units because this is much more difficult to enforce
and will result in minimal additional HAP control.
     The procedures for compliance demonstration are written so
as not to require a separate definition of HAP control
efficiency.   Equation 1 in §63.824 has been rewritten to clarify
that volatile matter recovery efficiency can be assumed to be
equivalent to organic HAP recovery efficiency.   The extent to
which phthalates and other organic HAP are retained on the
printed substrate has not been established.   These compounds may
be emitted under some circumstances,  thus they have not been
excluded through a definition of HAP emitted.
     In the final rule,  the definition of capture efficiency has
been clarified.   The commenter was correct that the intent of
                              2-23

-------
this definition was that captured HAP must be delivered to the
control device.
     In the final rule, the definition of research or laboratory
facility is based on the definition in Section 112(c)(7) of the
CAA.  The EPA does not have sufficient information that "de
minimis manner" could be defined for this source category.
     Definitions of "coating operation" and "stand-alone coating
equipment" have been added to clarify the scope of the rule.
2.10  REPORTING
     Comment:   Two comments were received requesting
clarification that only reports applicable to the specific
control strategy employed were required.   Commenter IV-D-1
suggested that the rule require only applicable reports.
Commenter IV-D-15 requested explicit exemption from initial
notification,  performance test notification,  and performance test
reporting for sources complying by means of liquid-liquid mass
balances.
     Commenters IV-D-1 and IV-D-36 suggested synchronizing the
required semi-annual reports with required Title V reporting.
     Three comments were received requesting the elimination of
redundant reporting requirements.  Commenters IV-D-36 and IV-D-63
suggested eliminating HAP usage reporting requirements if this
was already a condition of the State operating permit.
Commenter IV-D-50 suggested that the requirement for an annual
statement of compliance was redundant with other General
Provisions requirements.
     Five comments were received regarding the initial
notification requirements.  Commenters IV-D-37 and IV-D-39
suggested extending the notification period from 120 to 180 days
because 120 days is insufficient for notification, guidance and
resubmission.   Commenter IV-D-79 recommended extending the
initial notification period to 270 days.   Commenter IV-D-53
requested language in the rule to indicate that the Title V
application constitutes initial notification.  Commenter IV-D-49
requested that area sources be required to submit initial
                               2-24

-------
notifications so that the States will know who they are and what
they are doing.
     Commenters IV-D-1 and  IV-D-53 suggested requiring reporting
of  "HAP emitted" rather than  "HAP used".  Commenter IV-D-51
requested that sources meeting the requirements of §63.821(a)(2)
of  the proposed rule be allowed 60 days rather than 30 days for
reporting of annual HAP usage because of delays expected as a
result of required testing  methods.  Commenter IV-D-54 suggested
exempting affected sources  that do not use HAP from all reporting
other than an annual statement to this effect.
     Commenter IV-D-54 suggested clarifying that only an estimate
of  HAP use is required for  the period 12 months prior to
notification, because no records will be available based on the
required test methods.
     Commenter IV-D-4 feels that reporting requirements should be
reduced for flexographers (relative to rotogravure printers) so
that the cost of reporting  is in line with the expected emission
reductions.  Commenter IV-D-25 feels that the reporting
requirements are excessive  and may be in violation of the Federal
Paperwork Reduction Act.   Commenter IV-D-81 recommended
eliminating reporting for area sources that are distinctly below
the 10/25 threshold and requiring only on-site recordkeeping.
Commenter IV-D-81 suggested eliminating all reporting
requirements except for an annual certification.
Commenter IV-D-81 suggested eliminating the requirement for
documentation of deviations from the startup,  shutdown,  and "
malfunction report except when the standard is not met as a
consequence of the deviation.
     Commenter IV-D-88 suggested delegating the authority to
require reports to the permitting authority.
     Response:   Reports required under §63.830(b)(6)  of the
revised rule are to be submitted as applicable.   In accordance
with §63.10(e)(3)(i)  of the General Provisions,  reportable excess
emissions and parameter exceedances are defined in §§63.824-825
of the revised standard.
                              2-25

-------
     Section 63.10(a)(5) of the General Provisions applies to
this standard.  This  section provides that the dates by which
periodic reports shall be submitted can be changed to be
consistent with the State's schedule  (without changing the
frequency of reporting) by mutual agreement between the owner or
operator and the State.  Procedures governing the implementation
of this provision are specified in §63.9(i) of the General
Provisions.
     HAP as defined under different State air toxics control
programs may not coincide with HAP listed in §112(b)  of the CAA,
therefore HAP usage reporting requirements may not be redundant
and have been retained.  The requirement for an annual statement
of compliance has been retained; however -the standard does not
preclude submission of this statement as part of, or in
conjunction with,  a periodic report.
     Initial notification is essential for the enforcement of the
standard, as it alerts permitting authorities to the presence of
affected sources.   Initial notification requirements for existing
sources have been extended until one year before the compliance
date.  This will allow potential sources more time to determine
whether they are subject to the standard and will have no adverse
impact on HAP emissions.  Conditions under which an application
for a Title V permit or a Part 70 permit may be construed as
initial notification are stated in the final rule.   In addition,
an application for approval of construction or reconstruction
under §63.5(d)  of the General Provisions can be used to fulfill
notification requirements.  The applicability of the standard and
all reporting requirements,  including initial notification, is
limited to facilities defined in §63.820(a).  Sources which use
the provisions of this standard to establish area source status
are required to submit initial notifications.  Sources which use
other mechanisms to establish area source status must comply with
the conditions of those mechanisms.  This standard does not limit
the authority of a State to require initial notification from
area sources under State laws.
                               2-26

-------
      The  requirement  to  include,  in  the  initial notification,  the
 amount  of HAP used by existing  sources in the 12 months preceding
 the notification,  has been  eliminated from the final rule to make
 it consistent with the General  Provisions and to decrease the
 reporting burden.
      Facilities meeting  the requirements of §63.820(a)(2) are
 required  to  submit annual HAP usage  reports no later than 30 days
 after the end of the  12-month reporting period.  Sources seeking
 to comply by means of this  provision are required to determine
 HAP usage for each 12-month period (i.e., to make a determination
 each  month and add it to the amount  for the preceding 11 months).
 The EPA feels that 30 days  is sufficient time to make this
 determination for  the last  month  in  the 12-month reporting
 period, do the summation, and submit the report.  The General
 Provisions §63.9(i) (2) provide  a means by which an owner or
 operator  can request  an extension.
      Affected sources  that  do not use HAP may comply on a
 facility-wide basis under §63.825(b)(1).   Recordkeeping
 (including records demonstrating that inks and other materials do
 not contain  HAP)  is essential to ensure compliance.   Alternately,
 affected  sources that do not use HAP may use the provisions of
 §63.820(b) to simplify recordkeeping and avoid all routine
 reporting.
     The  standard  for wide-web  flexography is equal  to that for
product and packaging rotogravure.  Equal reporting  requirements
are necessary to ensure compliance with the standard.   The
reporting  requirements specified in the General Provisions as
well as the additional requirements proposed in this subpart have
been reviewed in accordance with the Paperwork Reduction Act and
an Office  of Management and Budget control number has  been
issued.   Sources using the provisions of  the rule to establish
area source status are subject  to reporting requirements only in
cases where the area source commitment is not met.   The EPA feels
that the reporting requirements in the final rule are  the minimum
necessary  to ensure compliance  with the standard.  These reports
                              2-27

-------
alert the permitting authority to excess HAP emissions,
malfunctioning or improperly operated capture, control and
monitoring equipment, and unapproved startup, shutdown, and
malfunction procedures.
     The purpose of the startup, shutdown, and malfunction plan
is to ensure compliance with the standard.  Documentation and
reporting of deviations from the startup, shutdown, and
malfunction plan is essential to allow the permitting authority
to determine when violations of the standard may have occurred.
     States may use the provisions of §112(1) of the CAA to
obtain a partial or complete delegation of the Administrator's
authorities under this standard.
2.11  LEVEL OF CONTROL FOR PRODUCT AND PACKAGING ROTOGRAVURE AND
WIDE-WEB FLEXOGRAPHIC PRINTING AFFECTED SOURCES
     Comment:   Eight comments were received which support the
level of control specified in the rule.  Commenters IV-D-1,
IV-D-36, IV-D-53, and IV-D-55 support the proposed standard.
Commenter IV-D-4 stated that catalytic oxidizers can regularly
obtain destruction rates of 99 percent and,  thus, considered the
standard appropriate.  Commenter IV-D-7 stated that 95 percent
overall control efficiency is achievable and that catalytic
oxidizers can reach 98 percent destruction efficiency.
Commenter IV-D-36 stated that catalytic oxidizers can obtain
98 percent and higher control device efficiency.
Commenter IV-D-25 stated that 95 percent overall control
efficiency is achievable and common.
     Eight comments were received questioning the determination
of the MACT floor.   Three commenters (IV-D-15, IV-D-40, and
IV-D-50) stated that the MACT calculation was biased because
point (test)  data were used rather than ranges of operating
conditions.  Commenter IV-D-50 stated that the database was
adequate if the control equipment is required to pass a test at
95 percent but not consistently meet this standard.
Commenter IV-D-15 felt that the data base used was too small
relative to the size of the industry.  Commenter IV-D-61 stated
                               2-28

-------
that the MACT floor is not supportable for facilities with
ancillary printing because the database used was not
representative of this type of facility.  Commenters IV-D-50 and
IV-D-84 stated that it is inconsistent to regulate publication at
92 percent overall control efficiency and expect 95 percent from
packaging rotogravure because the technologies are similar.
     Commenter IV-D-38 stated that actual emissions rather than
potential to emit were used to determine which sources were
included in the MACT floor determination and that this biased the
determination.
     Commenter IV-D-4 stated that it is inappropriate to group
flexography with rotogravure and that flexography should be a
separate subcategory.
     Commenter IV-D-82 stated that the database did not
adequately represent the decorative foil segment of the
rotogravure industry and that these facilities should be exempt
from the standard.
     Response:   Many of the data upon which the MACT floor
determination were based, were in fact, the most recent onetime
test data available.  These data are consistent with the final
standard.  Owners or operators choosing to comply through the use
of control equipment may conduct an initial performance
demonstration to establish the efficiency under test conditions.
During the initial performance test, operating parameters are
also established.  The owner or operator must then maintain those
operating parameters.  The standard does not require owners or
operators complying in this way to continuously demonstrate the
control efficiency.   They must,  however,  continuously monitor the
operating parameters (typically oxidizer temperatures and a
parameter indicating that the capture system is operating in an
equivalent manner to its operation during the performance test).
Owners or operators may also comply through the use of continuous
emission monitors, and where solvent recovery systems are used,
through monthly liquid-liquid material balances.
                               2-29

-------
     The database contained a substantial proportion of sources
which will be affected by the standard,  and the EPA, in
cooperation with industry associations,  expanded it to the
greatest extent possible.  The database  included lines which had
both printing stations and coating stations.   The control
techniques for ancillary printing equipment and coating lines are
the same as those for product and packaging rotogravure and wide-
web flexographic presses.  The final rule does provide owners or
operators with the option of excluding ancillary printing
equipment from the affected source.   Such equipment, if excluded
from this standard,  will be subject  to the appropriate source
category standard when such a standard is issued.
     The comparison between the standard for publication
rotogravure and the standard for product and packaging
rotogravure and wide-web flexography is  not valid.   Publication
rotogravure sources must achieve a minimum of 92 percent overall
efficiency each and every month.  In order to meet  this standard,
average overall efficiencies are likely to be substantially
higher.  Product and packaging rotogravure and wide-web
flexography sources are required to  demonstrate 95  percent
overall efficiency under test conditions, establish operating
parameters during the test, and maintain those operating
parameters.  This is not, necessarily, equivalent to achieving
95 percent overall efficiency on a monthly average, each and
every month.   In both cases, the form of the final  standard was
consistent with the database used to develop that standard.
     Actual emissions were not used  to determine which sources
were included in the MACT floor determination.  Rather, potential
emissions were estimated to make this determination.  Wide-web
flexography was grouped with product and package rotogravure
because many "hybrid" presses are in operation which include both
rotogravure and flexographic print stations.   If a separate
subcategory had been established for flexography, the MACT floor,
                               2-30

-------
 and  thus,  the  standard,  for  this category would be  identical to
 *
 that established  for  the combination.  The database contains
 numerous  film  and foil printers including sources in the roll
 leaf and  decorative foil industries.  Capture and control
 equipment available for  use  in the decorative foil  industry is
 similar to that available to the product and package rotogravure
 industry  in general.
 2.12  LEVEL OF CONTROL FOR PUBLICATION ROTOGRAVURE AFFECTED
 SOURCES
     Comment:  Commenter IV-D-7 supported the proposed standard
 and stated that control  devices can meet the 92 percent overall
 efficiency standard.
     Commenter IV-D-37 requested that an explicit de minitnis HAP
 content be established as a  compliance alternative for operation
 without a  control device.  Commenter IV-D-38 requested that
 regulatory alternatives  more stringent than the MACT floor be
 considered.
     Response:  The de minimis organic HAP content for
 publication rotogravure  facilities operating without a control
 device is  eight percent  of the volatile matter used.  If the inks
 used in a  month contain  less than 0.08 kg organic HAP per kg of
 volatile matter (including water),  the facility would be in
 compliance  without a control device.   This has been clarified in
 §63.824(b)(3).
     The EPA believes that,  based on facility material balance
 data, the  standard for existing publication rotogravure
 facilities, 92 percent overall control on a facility-wide basis
 to be achieved each and every month,  will require an efficient
 capture system and a state-of-the-art control device.   There is
 no distinct identifiable technology available to new sources
which would allow them to achieve a more stringent standard.

2.13  STANDARDS FOR PRODUCT AND PACKAGING ROTOGRAVURE AND WIDE-
WEB FLEXOGRAPHIC PRINTING AFFECTED SOURCES
     Comment:  Seven commenters (IV-D-1, IV-D-15, IV-D-17,
IV-D-36, IV-D-51, IV-D-53, and IV-D-63) suggested revising the
standard to allow the use of control devices to meet the low-HAP/
materials applied standard.
     Four commenters (IV-D-1, IV-D-36, IV-D-53, and IV-D-63)
noted an error in §63.825 (f) (5) of the proposed rule where the
words "material applied" should have appeared instead of "solids
applied."
     Three commenters requested clarification of §63.825(b) (1)
and (2)  to reflect that presses applying low HAP materials do not
need control devices.  Commenters IV-D-15 and IV-D-51 suggested
addition of the word "and" between the sections.
Commenter IV-D-63 suggested language clarifying that sources need
only comply by one mechanism.  Commenter IV-D-51 requested
clarification that a combination of add-on control and reduced
HAP materials will meet the standard, suggesting that the
language in the proposed rule could be interpreted to allow this
only for solvent recovery systems.
     Commenter IV-D-53  requested clarification that organic HAP
contents of materials are expressed "by weight."
     Commenter IV-D-82  requested a 20 parts per million (ppm)
control device exhaust  limit as an alternative to 95 percent
control.
     Response:   The standard has been revised to allow the use of
control devices to meet the low-HAP/materials applied limitation.
The revised standard has been clarified to enumerate the
different ways in which a source can comply and make it clear
that only one means of  compliance is necessary.  The error in
§63.825(f)(5) of the proposed regulation has been eliminated from
the final regulation.  The final regulation permits the use of
control devices  (not restricted to solvent recovery systems), as
well as a combination of control devices (not restricted to
solvent recovery systems) and low-HAP materials to comply.
                               2-32

-------
      The final  regulation provides  for  compliance on an affected
 source-wide basis.   Control  devices are not required on presses
 applying low-HAP  materials provided that the affected source
 achieves compliance  by one of  the mechanisms listed in §63.825.
      The variables in the equations used to determine compliance
 are  defined in  §63.822.   The units  given in the definitions in
 both the proposed and final  rule establish that the organic HAP
 contents of materials applied  are expressed "by weight."
 Affected sources  may comply  on the  basis of HAP emitted/material
 applied,  HAP emitted/solids  applied, or HAP emitted relative to a
 calculated  allowable mass emission  level based on materials
 applied  and solids applied,  or overall  control efficiency.
 Affected sources  complying on  the basis of overall control
 efficiency  may  demonstrate 95  percent control under "test
 conditions"  and then maintain  the appropriate control device
 operating parameters.  Affected sources operating solvent
 recovery systems  may demonstrate compliance through liquid-liquid
 material balances.   The actual control  device exhaust
 concentration would  be of  interest  only for sources complying
 through  the  use of continuous  emissions monitors across the
 control  device.   Compliance  on the  basis of 20 ppm exhaust gas
 concentration would  be inconsistent with the database used to
 establish the standard, however,  it is expected that such sources
 would be  in  compliance and could demonstrate compliance based on
 HAP emitted/material applied, HAP emitted/solids applied or
 calculated allowable HAP emissions.
 2.14  COMPLIANCE FOR PUBLICATION ROTOGRAVURE AFFECTED SOURCES
     Comment:  Three comments were  received on provisions for
 compliance by liquid-liquid mass balance.   Commenters IV-D-38 and
 IV-D-49  requested clarifying the procedure for accounting for
 recovered mixtures of HAP  and non-HAP volatile matter.
 Commenter IV-D-15 requested explicit acknowledgement that
 recovered solvent can be assumed to contain the same fraction of
HAP as the volatile matter present in the ink.
                              2-33

-------
     Response:  The final rule includes this provision in
§63.824(b).  In practice, the recovery efficiencies of organic
HAP and non-HAP organic volatile matter are equivalent for the
solvent blends used in the publication rotogravure industry.  The
recovered solvent is reused within the facility and the excess is
sold back to the ink manufacturer for production of more ink.
This is feasible because recovered solvent has the same
composition as the solvent used to manufacture the ink.
2.15  MONITORING
     Comment:   Seven comments were received regarding the
requirement to measure vent stream flow rates.  Commenter IV-D-1
suggested allowing vent stream flow rate to be determined from
fan amperage.   Commenter IV-D-36 suggested allowing the use of
fan indicators, fan rotation indicators, or press interlocks and
allowing the system to be operated at different rates than those
used for the performance test.  Commenter IV-D-63 recommended
allowing other devices, including press interlocks instead of
flow meters.  Commenter IV-D-84 suggested requiring only flow
indicators and not press-by-press flow meters.
Commenters IV-D-15 and IV-D-84 suggested allowing alternate
devices for flow measurements when the physical layout does not
permit placement of the flow meter as required in the proposed
rule.
     Commenter IV-D-53 suggested eliminating the requirement for
flow rate monitoring because it has no relevance in the
converting industry.  Commenter IV-D-51 stated that flow
monitoring is  useless, except for sources complying by means of
continuous emissions monitoring.
     Three comments were received concerning thermocouple
requirements for monitoring oxidizers.   Commenter IV-D-15
suggested eliminating the requirement for routine thermocouple
calibration or replacement.  Commenter IV-D-36 stated that
thermocouples  are difficult and expensive to calibrate and that
the act of recalibration may increase the likelihood of system
                               2-34

-------
 failure.   Commenter  IV-D-54 stated that the required thermocouple
 accuracies are unnecessarily strict and requested limits of
 two percent or _+  1 degree Celsius.  Commenter IV-D-54 also
 suggested  providing  flexibility for the thermocouple location.
     Three comments  were received suggesting alternatives to
 continuous monitoring. Commenter IV-D-14 suggested allowing
 initial capture and  control tests, weekly recording of materials
 usage, and monthly reduction to emission rates, as well as
 continuous temperature monitoring for oxidizers.  No additional
 testing should be required unless the permitting authority thinks
 it is necessary.  Commenter IV-D-25 suggested requiring control
 equipment  tests every three years plus measurements of
 temperature rise  (across catalytic oxidizers)  and pressure
 differential, and eliminating burdensome three hour period
 temperature monitoring requirements.   The commenter stated that
 most State and local EPA officials prefer this approach.
 Commenter  IV-D-25 also suggested exempting sources with permanent
 total enclosures from monitoring with a requirement for a
 performance test every three years.   Commenter IV-D-25 also
 recommended exempting sources with presses interlocked to control
 device operating parameters from testing and monitoring
 requirements.  Commenter IV-D-36 suggested exempting sources
 complying by means of liquid-liquid mass balances from parameter
monitoring requirements.
     Commenter IV-D-15 suggested that the rule not specify
performance criteria for solvent recovery system cumulative
 recovery measurement instrumentation,  and that mass balance
provisions require that water input  be measured,  but that only
volatile organic matter (and not water)  be recovered and
measured.
     Commenters IV-D-36 and IV-D-63  suggested eliminating
startup,  shutdown, setup,  rewebbing  and changeover periods from
temperature monitoring requirements.
     Commenters IV-D-36 and IV-D-63  requested guidance on the
selection of the capture  system parameter.   Commenter IV-D-49
                              2-35

-------
suggested requiring continuous monitors under §63.824(b) (1) (ii)
of the proposed rule to assure that the capture efficiency is the
same as the capture efficiency determined during the performance
test.
     Two comments were received regarding performance tests and
the establishment of oxidizer operating parameters.  Commenter
IV-D-49 suggested conducting performance tests under both high
load and low load conditions and suggested that required oxidizer
operating parameters be established based on worst-case  (i.e.,
shortest retention time and lowest temperature)  conditions.
Commenter IV-D-84 suggested requiring performance testing under
normal, as opposed to maximum, conditions.
     Commenter IV-D-82 stated that it would- be more practical to
require averaging of operating parameters over 24 hours  (instead
of three hours) because frequent short jobs and changeover
periods would make it difficult to calculate averages over the
applicable time periods.
     Commenter IV-D-51 suggested that excursions in operating
parameters should not be considered violations,  but only trigger
a potential request to re-test the control system from the
permitting agency.  Commenters IV-D-16 and IV-D-36 recommended
more flexible monitoring requirements with exceedances triggering
a maintenance response as defined in a standard operating
procedure.  Excessive malfunctions could trigger a stack test
request by the State.
     Two comments were received concerning delegation of
authority.  Commenter IV-D-39 suggested delegating all monitoring
approval to the permitting authority.  Commenter IV-D-39
suggested delegating approval of operating parameters to the
permitting authority.
     Commenter IV-D-36 suggested that monitoring equipment
accuracy not be specified in the rule but be held at
manufacturers specified level and stated that auditing of
continuous emission monitors would be difficult.
                               2-36

-------
      Commenters  IV-D-36  and  IV-D-53 suggested removing all
 i
 monitoring requirements  from the rule until the EPA formulates a
 new monitoring rule.
      Response:   The  final  regulation includes alternatives to the
 vent  stream flow rate measurement requirement.  Owners or
 operators  of product and packaging rotogravure and wide-web
 flexographic presses with  intermittantly-controllable work
 stations may, as alternatives to measuring vent stream flow rate,
 install flow indicators  on the bypass lines, secure bypass line
 valves with locking mechanisms or car seals, continuously monitor
 bypass valve position or equip the press with an interlock
 preventing operation when  the control device is bypassed.  These
 are acceptable alternatives  to vent stream flow rate monitoring
 because they ensure that control devices are not bypassed.
 Sampling lines for gas analyzers and relief valves needed for
 safety purposes  are not  considered bypass lines for the purposes
 of these provisions.  Presses that do not have any
 intermittently-controllable  work stations are not subject to
 these provisions.
     Accurate temperature monitoring is essential to ensure that
 oxidizers  are routinely operated at the same efficiency as
 demonstrated during the performance test.  If temperature
monitoring equipment is not  calibrated periodically it is
 impossible  to ensure continuous compliance with the standard.
The final  rule has been changed to clarify that all temperature
monitoring  equipment must be installed,  calibrated,  maintained,
and operated according to manufacturers specifications;  and that
 the chart  recorder, data logger,  or temperature indicator (rather
than the thermocouple or temperature sensor)  must be calibrated
every three months.  In the unlikely event that the type or
layout of  the control equipment makes it impossible to reliably
calibrate  the temperature monitoring equipment on a periodic
basis, sources may comply through the installation of continuous
emission monitors.
                              2-37

-------
     The final rule has been changed to require thermocouple
accuracies of ± 1 degree Celsius or +. 1 percent of the
temperature being monitored in degrees Celsius.  In practice this
provides for an accuracy of ± 2 to eight degrees Celsius which is
well within the accuracy attainable using thermocouples with
analog or digital chart recorders, voltmeters, or data loggers.
The EPA considers that the requirement for locating thermocouples
or temperature sensors "in the combustion chamber downstream of
the combustion zone" or "at the nearest feasible point to the
catalyst inlet," provides adequate flexibility.
     Sources operating control devices must monitor an operating
parameter or parameters to ensure that the control device is
operating at the same or higher efficiency as that achieved
during the initial compliance demonstration.  As an alternative,
continuous emission monitors may be installed across the control
device and monitored to ensure compliance.  In addition, sources
operating control devices,  except for those in permanent total
enclosures,  must monitor an operating parameter to ensure that
capture efficiency is the same as, or higher than,  the capture
efficiency achieved during the compliance demonstration.  These
requirements do not apply to sources operating solvent recovery
systems and demonstrating compliance by means of monthly liquid-
liquid material balances.  The three hour averaging period for
oxidizer temperature monitoring allows for transient temperature
fluctuations which may occur due to press operating conditions.
If temperatures are consistently maintained above the established
operating parameter levels, then averaging is unnecessary
because,  if the temperature is always greater than the operating
parameter,  the average temperature will be greater than the
operating parameter.
     Monitoring temperature rise across the catalyst bed instead
of the temperature upstream of the catalyst is not expected to
provide any decrease in equipment cost or monitoring and
recordkeeping labor.  A source may seek approval of any alternate
monitoring plan.  The pressure differential across the catalyst
                               2-38

-------
bed may not be  indicative of performance and may not ensure
continuous compliance.   Issues relating to catalytic oxidizer
monitoring are  discussed further in Section 2.22.
       Sources  with permanent total enclosures must maintain the
conditions necessary  for a permanent total enclosure.  Such
sources are still required to monitor parameters to ensure that
the control device efficiency is equal to or greater than the
efficiency established during the compliance demonstration test.
     Presses interlocked to prevent operation when monitoring
parameters are  not maintained would meet a stricter standard than
presses maintaining operating parameters on average for every
three hour period, because if the parameters are always
maintained, then clearly they are maintained on average.  An
owner or operator seeking to comply by interlocking the presses
to prevent operation  at  any time when the parameters were not
maintained could satisfy monitoring requirements simply by
monitoring that the interlock system was in good working order
and had not been overridden.  Initial compliance testing would
still be required to  establish the monitoring parameter levels
which would ensure compliance.   Sources complying by liquid-
liquid material balances are exempt from parameter monitoring
requirements.
     The data on which liquid-liquid material balances are based
must be accurate to ensure compliance with the standard.  The
performance criteria  in  the final rule are necessary to prevent
generation of erroneous material recovery data.   The language in
the final rule has been  revised to clarify the standard does not
require instrumentation  to be removed from service and shipped to
the manufacturer for  calibration and certification.   It is
necessary to measure  all volatile matter,  including water,  to
ensure the validity of the organic HAP recovery determination.
Solvent recovery systems are rarely,  if ever,  used with
waterborne ink systems.   Water vapor,  if present at significant
levels in the  dryer exhaust,  could decrease the organic HAP
recovery capacity of the sorbent.   If water and water soluble
                              2-39

-------
organic matter are not measured, the composition of the recovered
volatile matter cannot be determined.
     Monitoring during periods of startup and shutdown must be
addressed in the startup, shutdown, and malfunction plan for each
affected source.  It is appropriate to require temperature
monitoring during periods of setup, rewebbing, and changeover
because of the potential for emissions during these periods.
     Selection of the operating parameter to ensure the proper
operation of the capture system depends on the conditions,
equipment, and layout of each individual site.  Under some
circumstances relative pressure measurements, exhaust flow rate
measurements, linear velocity measurement systems at pressroom
intakes, fan amperage, or some combination of these parameters
and/or other parameters might be appropriate.  The selection of
this parameter is part of the permit application process.
Continuous emission monitors, along with a measurement of ink
usage could be used to ensure capture efficiency,  however,  the
final rule does not require the use of continuous emission
monitors because of costs associated with equipment installation,
operation, calibration,  and maintenance.
     Consistent with the General Provisions,  performance testing
is to be conducted under such conditions as the Administrator
specifies to the owner or operator based on representative
performance {i.e.,  performance based on normal operating
conditions)  of the affected source.  Since the final rule does
not require owners or operators of catalytic oxidizers to monitor
the temperature downstream of the catalyst, performance testing
under multiple conditions will not be required for the purpose of
establishing a representative downstream operating temperature.
     A three hour averaging period has been retained in the final
rule to allow for brief temperature variations which may occur
when presses are switched on or off.  A 24 hour averaging period
for operating parameters may be too long to ensure continuous
compliance with the standard, however,  individual sources may get
approval for alternative recordkeeping systems.  The requirement
                               2-40

-------
 to average parameters over a three hour period will not result  in
 significantly greater recordkeeping labor than a requirement to
 average over 24 hours.
      In order to ensure continuous compliance, operating
 parameters are established during the performance demonstration
 test.  If continued operation were permitted during lengthy
 periods when operating parameters are not maintained, lengthy
 periods of excess emissions might result.  Sources have the
 option of using continuous emission monitors as an alternative  to
 monitoring operating parameters.  Sources unable to conduct
 reliable audits of continuous emissions monitors, as required,
 may monitor operating parameters instead of operating continuous
 emission monitors.
     The permitting authority must approve the selection of
 operating parameters.  Owners or operators may request approval
 of an alternative monitoring method (and corresponding
 recordkeeping system) under §63.8(f)  of the General Provisions.
     The final rule contains specifications for the accuracy of
 thermocouples used to monitor control device efficiency and
 measurement equipment used to collect data for liquid-liquid
 material balances.  Equipment meeting these specifications is
 readily available and has been in use for many years.  Owners or
 operators choosing to demonstrate compliance by means of
 continuous emission monitors must select,  install,  operate, and
maintain monitors which are capable of being audited to ensure
 compliance with the standard.
     Monitoring is required to ensure continuous compliance with
the rule.   Owners or operators using capture systems and control
devices would be unable to certify compliance with the standard
without monitoring data.
 2.16  COMPLIANCE DATES FOR NEW SOURCES
     Comment:   Seven comments were received concerning the
 triggering of  new source compliance deadlines as a result of
adding new equipment.   Six comments (IV-D-15,  IV-D-36,  IV-D-51,
IV-D-60,  IV-D-63,  and IV-D-84)  involved the addition of new
                              2-41

-------
presses to common control systems.  Commenters IV-D-15, IV-D-51,
and IV-D-63 suggested that the addition of new presses to
affected sources should not render the entire facility
(publication) or group of commonly controlled presses  (package
and product) a new source.  Commenters IV-D-36 and IV-D-84 stated
that this would make it impossible to comply with "shelf life
certification requirements."  Commenters IV-D-36 and IV-D-60
stated that this would make it impossible to take advantage of
the three year period to convert to low HAP materials.
     Three commenters (IV-D-17, IV-D-36, and IV-D-63)  felt that
addition of a new station to a product and packaging press should
not render the entire press a new source and that the new station
should comply separately as a new affected source.
     Commenter IV-D-53 requested clarification of whether the
addition of a new inline coating station or outboard deck makes
the line a new source.
     Response:   The final rule provides that reconstructed
sources must meet the compliance date established for new
sources.  Addition of one or more presses to an existing facility
would not trigger the new source compliance date unless the
additions were extensive enough to constitute a reconstruction.
Addition of a new inline coating station or outboard deck to an
existing facility would not trigger the new source compliance
date unless the additions were extensive enough to constitute a
reconstruction.  Since the final rule considers the affected
source for product and packaging rotogravure and wide-web
flexographic printing facilities to be all of the presses located
at the facility (subject to certain exclusions given in §63.821)
addition of a single press to an existing facility,  or addition
of one or more stations to an existing press would not
necessarily constitute a reconstruction of the facility.
Furthermore, §63.826(c)  excludes the costs associated with
purchase and installation of air pollution control equipment from
the determination of whether a facility has been reconstructed,
consistent with the EPA's general policy regarding the cost of
                               2-42

-------
control equipment  (59 FR 12421).  Costs of modifying equipment to
*
make it compatible with low HAP ink formulations that will be
used to meet the requirements of this rule are also excluded from
this determination.
2.17  COMPLIANCE DATES-GENERAL ISSUES
     Comment:  Commenter IV-D-39 suggested that the final
compliance date should be 30 days after final action by the EPA
on the Section 112(1) equivalency request, provided the request
is submitted within one year of promulgation.  This will avoid
the requirement for sources to comply with dual State/Federal
regulations.
     Commenter IV-D-82 requested a longer compliance deadline for
facilities with oxidizers presently meeting reasonably available
control technology (RACT)  because costs will be very high to
obtain only marginal emission reduction.
     Response:  The CAA requires existing sources to comply no
later than three years after promulgation, regardless of RACT
rules.  Facilities with oxidizers may still take advantage of the
compliance options in the rule, including the use of low-HAP
materials.  The final rule provides flexibility for owners or
operators to comply through the use of control devices,  through
the use of low-HAP materials, or through a combination of these
means.
     The EPA determined that a three year compliance deadline for
existing sources was appropriate based on the length of time
required for sources complying through the use of upgraded
capture and control equipment to design, gain approval for,
contract for, retrofit,  and test the additional equipment.  A
compliance deadline of 30  days after approval of a Section 112(1)
request could be less than three years from promulgation and
might be inadequate.   Section 63.10(a)(5)  of the General
Provisions applies to this standard.   This section provides that
the dates by which periodic reports shall be submitted can be
changed to be consistent with the State's schedule (without
changing the frequency of  reporting)  by mutual agreement between
                               2-43

-------
the owner or operator and the State.   Procedures governing the
implementation of this provision are specified in §63.9(i) of the
General Provisions.
     New sources are required to comply on startup or on the date
of promulgation, whichever is later.   An operating permit could
not be granted to a new source that was not capable of complying
during the period between promulgation or startup and the
approval of a Section 112(1) program.
2.18  HAP CONTENT DETERMINATION
     Comment:  Ninety-six comments were received stating that
they would prefer to use formulation data rather than Method 311
because the formulation data are more accurate and less
burdensome.  Commenter IV-D-4 requested that Method 311 be
evaluated before becoming a requirement. Commenter IV-D-79
expressed concern about Method 311 and referred to comments
submitted on the Wood Furniture standard.
     Three commenters (IV-D-1,  IV-D-6,  and IV-D-63)  recommended
that manufacturers formulation data be accepted providing that
all HAP in excess of 0.1 percent by weight are listed.
Commenter IV-D-36 states that the provision in the proposed wood
furniture standard,  (i.e.,  formulation data with a one percent
de minimis, 0.1 percent for Occupational Safety and Health Act
carcinogens plus a demonstration that there is no release of HAP
cure products)  would be acceptable.  Commenter IV-D-62 presented
comparative analytical data from Method 311 analyses of furniture
coatings containing some of the HAP of concern and found very
poor interlaboratory reproducibility.  They further stated that
they were unable to recommend a suitable method and that the
chemical industry had never been able to develop a suitable
method.  They suggested using formulation data and a
1/0.1 percent de minimis.  Commenters IV-D-52 and IV-D-53
suggested a 1/0.1 percent de minimis.  Three additional
commenters (IV-D-15, IV-D-21, and IV-D-59) recommended a
one percent de minimis.
                               2-44

-------
     Commenter IV-D-28 recommended establishing a de minimis
level consistent with SARA 313 requirements.  Four commenters
 (IV-D-25,  IV-D-50,  IV-D-51, and IV-D-82) suggested use of MSDS or
other available information to avoid prohibitive analytical
costs.
     Three commenters (IV-D-1, IV-D-53, and IV-D-63) suggested
changing the wording and requiring HAP content to be determined
rather than identified.   This would allow printers to rely on
data from  ink manufacturers.
     Commenter IV-D-14 stated that Method 311 is likely to be
acceptable and suggested the use of American Society for Testing
and Materials (ASTM) D3432-80 for toluene diisocyanate, if
necessary.  Commenter IV-D-15 recommended using SW 846 methods
 (specifically direct injection capillary gas chromatography (GC)
methods) instead of Method 311.  Commenter IV-D-39 suggested the
use of ASTM E260-91.  Commenter IV-D-36. recommended changing
Method 311 by modifying the quality assurance/quality control
procedures to reflect the use of capillary columns,  eliminating
matrix spikes, eliminating chain of custody procedures for on-
site analyses, and allowing alternatives to dimethylformamide.
These changes were expected to save a large ink manufacturer an
estimated $70 million per year.  Commenter IV-D-66 conducted
Method 311 and found an 18 percent error with a known standard of
butyl cellosolve and a 14 percent error with a known standard of
methanol.
     Commenter IV-D-6 manufactures 70-80 batches of  ink per day
and estimates a cost of  $500 per sample leading to a minimum
annual cost of $8.4 million.  Commenter IV-D-17 estimated that a
medium sized printer would spend $750,000 per year doing
Method 311 on 1000 formulas.  Commenter IV-D-28 estimated annual
costs of $4.5 million annually for one plant and $216 million
annually company-wide.   Commenter IV-D-21 estimated that a small
ink manufacturer would incur costs of $5 million to  $10 million
per year plus a $30,000  capital expenditure in conducting ink
analyses.  Commenter IV-D-33 estimated costs at $2 million to
                               2-45

-------
$3 million if they must analyze press ready inks which have been
diluted only with non-HAP materials.  Commenter IV-D-51 estimated
ink analysis costs of up to $7.5 million per year for a typical
printer.  Commenter IV-D-52 stated that the failure to specify a
de minimis penalizes analysts with sensitive equipment.
Analytical costs for their ink company would be $21-$77 million
for initial analysis.
     Three commenters (IV-D-6, IV-D-21, and IV-D-59)  stated that
the requirement to conduct Method 311 would interfere with their
typical short lead time order/delivery schedule.
     Commenter IV-D-15 suggested including provision for a
facility to concede that organic volatile material is 100 percent
HAP and avoid the need for an analysis.  Commenter IV-D-38
recommended that redetermination not be required when solvents
are switched,  if a worst case calculation demonstrates no
increase in HAP content.
     Commenter IV-D-39 recommended allowing State and local
agencies flexibility to determine the appropriate analytical
methods.
     Response:   The final regulation retains the use of
Method 311, as modified and promulgated with the final rule for
wood furniture coating.   The Method allows the use of any
analytical system employing GC provided that the prescribed
quality control,  calibration,  and method performance requirements
are met.   The Method has been revised to include a simplified
calibration procedure.   The Method has also been revised to
permit the use of recording integrators as alternatives to strip
chart recorders,  digital flow meters as an alternative to soap
film meters,  and the use of solvents other than
dimethylformamide.   Revisions made to Method 311 prior to the
promulgation of Method 311 are consistent with the apparatus and
methodologies suggested by the commenters.
     The final regulation also permits printers to rely on
formulation data provided that it meets certain requirements.
Formulation data provided by suppliers of inks and other
                               2-46

-------
 materials  can be used  if all organic HAP which is present at a
 level of 0.1 weight-percent or greater in any raw material used
 in  the  formulation  is  accounted for.  In the event of any
 inconsistency between  the EPA Method 311 test data and a
 facility's formulation data, that is, if the EPA Method 311 test
 value is higher, the Method 311 test data shall govern, unless
 after consultation, an owner or operator demonstrates to the
 satisfaction of the enforcement authority that the formulation
 data are correct.
     It should be noted that, for most organic HAP, the de
 minimis concentration  for formulation data used for compliance
 with the final rule is lower than the de minimis concentration
 for MSDS.  This lower"de minimis is necessary because the
 compliance options for package and product rotogravure and wide-
 web flexographic printing include the use of materials which
 contain less than four weight-percent organic HAP.  A de minimis
 of one percent organic HAP might not be stringent enough to
 ensure compliance under some materials averaging strategies,  and
 could result in less stringent requirements for overall control
 device efficiency.
     The final rule includes provisions by which owners or
 operators may determine the volatile matter content of materials
 and use this value in lieu of the organic HAP content for all
 compliance purposes.  Owners or operators choosing to comply in
 this way would not be required to conduct Method 311
 determinations.
 2.19  METHOD 24/24A
     Comment:   Nine comments were received (IV-D-6,  IV-D-15,
 IV-D-21, IV-D-28,  IV-D-36,  IV-D-51,  IV-D-52,  IV-D-53,  and
 IV-D-63) requesting that formulation data be considered as an
alternative to Methods  24 and 24A.   Commenter IV-D-28 estimated
costs of $250  per sample leading to $1.2  million for one plant
and $59 million company-wide.   Commenter  IV-D-36 estimated that
formulation data with random verification by 24/24A would save
$250-$300  per  sample.   Commenter IV-D-52  estimated costs of $3.5
                              2-47

-------
to $7 million if they cannot use formulation data instead of
Method 24/24A.
     Response:  The final rule provides that printers may rely on
the results of formulation data or Method 24/24A testing
conducted by suppliers of ink and other materials.  The owner or
operator must adjust these data as required to account for the
addition of dilution solvents at the printing facility.  In the
event of any inconsistency between the EPA Method 24 or 24A test
data and a facility's formulation data, the test data shall
govern, unless after consultation,  an owner or operator
demonstrates to the satisfaction of the enforcement authority
that the formulation data are correct.
2.20  OXIDIZER TERMINOLOGY
     Comment:   Four commenters (IV-D-1, IV-D-36, IV-D-53, and
IV-D-63)  suggested using the term oxidizer instead of incinerator
to distinguish vapor control devices from solid waste combustors.
     Response:  The final rule has  adopted the term oxidizer for
these control devices.
2.21  COMPLIANCE DEMONSTRATION-GENERAL ISSUES
     Comment:   Commenter IV-D-51 requested that §68.827(c) (2) (ii)
of the proposed rule be rewritten to include flexographic presses
which were inadvertently omitted.
     Four commenters (IV-D-1, IV-D-36, IV-D-53,  and IV-D-63)
recommended allowing the use of existing test data in lieu of an
initial compliance demonstration as compliance tests are very
expensive and duplication of effort should be avoided.
Commenter IV-D-36 requested explicit language that VOC control
efficiency can be used in lieu of HAP control efficiency and that
existing VOC test data can be used  for initial compliance
demonstration.  This provision could save $20,000-$25,000 per
test.  Commenter IV-D-25 suggested  applying VOC destruction test
data to the HAP/VOC ratio from MSDS to determine HAP emissions.
     Commenter IV-D-84 also requested explicit language that
overall HAP control efficiency is equal to overall VOC control
efficiency.  Commenter IV-D-50 endorsed the assumption of HAP
                               2-48

-------
 control  efficiency equivalent to VOC control efficiency as
 determined by  continuous  emission monitoring for thermal oxidizer
 compliance.
     Three commenters  (IV-D-15, IV-D-40 and IV-D-53) requested
 clarifying §63.825(d)  of  the proposed rule to make it clear that
 a source need  demonstrate compliance in only one of the three
 possible ways.
     Commenter IV-D-54 requested clarification that only the
 calculations,  recordkeeping, and reports applicable to the chosen
 compliance strategy are required.
     Commenter IV-D-4  stated that three hour periods for
 averaging  of operating parameter data may make compliance
 difficult.  Commenter  IV-D-81 recommended that not all
 exceedances be considered violations and that some number of
 exceedances per reporting period be allowed.   Commenter IV-D-50
 requests an allowance  for monthly variance (comparable to the UST
 program) in calculation of HAP/solids ratio for compliance.
     Commenter IV-D-15 recommended requiring compliance testing
 under conditions reasonably expected rather than maximum
 conditions.
     Commenter IV-D-36 suggested eliminating non-volatile,  non-
 emitted HAP such as MDI,  TDI,  and phthalates from the emission
 rate calculation.
     Commenter IV-D-36 suggested allowing material-by-material
 compliance to achieve either low-HAP or low-solids status at
 different  times on the same station.
     Commenter IV-D-38 requested additional compliance provisions
 for sources that do not operate control devices and suggested
 that all references to total volatile matter should be changed to
 total organic volatile matter or volatile matter less water to
make the standards more stringent.
     Response:   The final rule has been rewritten to include
wide-web flexographic presses along with product and packaging
rotogravure presses.  Wide-web flexographic presses were
inadvertently excluded from this section of the proposed rule.
                              2-49

-------
The proposal preamble made clear that wide-web flexographic
printing is regulated identically to product and package
rotogravure printing.  Provisions by which an owner or operator
may request a waiver of a required performance test are given in
§63.7(h) of the General Provisions.  It should be understood that
the initial performance test is used both to establish that the
capture system/control device is capable of meeting the standard
and to establish the values of operating parameters which must be
monitored to ensure continuous compliance with the standard.
Existing performance test data which does not clearly establish
operating parameters for the capture system and the control
device may not be suitable to establish compliance under the
standard. ~
     The performance test procedure in §63.827(d)  provides for
determination of organic volatile matter control efficiency.
These data can be assumed to be equivalent to organic HAP control
efficiency under most circumstances.  Language has been added to
the final rule to clarify this.
     The final rule has been revised to clarify that compliance
need be demonstrated under only one compliance option.
Calculations,  recordkeeping and reporting applicable to the
compliance option chosen are required.   As an example,
calculations,  recordkeeping and reporting to ensure control
devices are operating properly are not required of owners or
operators complying without the use of control devices.
Similarly,  owners or operators complying by means of solvent
recovery systems are not required to keep records and submit
reports applicable to oxidizers.   Owners or operators controlling
emissions through the use of solvent recovery systems and
complying by means of liquid-liquid material balances are not
required to conduct capture tests or monitor capture parameters.
     The rule requires continuous compliance.  The EPA considers
a three-hour averaging period sufficient to provide for transient
conditions which might occur during changes in press operations.
Longer averaging periods may allow operation with malfunctioning
                               2-50

-------
or improperly operated capture systems or control devices for
extended periods of time.  Periods longer than three hours might
not ensure continuous compliance.  Allowing one or more
exceedances per reporting period, or allowing a monthly variance
may not ensure continuous compliance with the standard.  Owners
or operators concerned that three-hour parameter averaging
periods are insufficient to avoid false indications of non-
compliance may choose to install and operate continuous emission
monitors.  Compliance with the low-HAP/solids or low-
HAP/materials standards must be demonstrated each and every
month.  Allowance of a variance would not ensure compliance each
and every month.
     The General Provisions require performance test conditions
to be based on "representative performance," that is, performance
based on normal operating conditions.   The final rule is
consistent with the General Provisions.  Owners or operators
wishing to establish that part of the organic volatile material
is not emitted may request approval of an alternate test method
by the Administrator.
     The final rule includes compliance options for product and
packaging rotogravure and wide-web flexographic printing
facilities that allow the use of either low-solids or low-HAP
materials,  or a combination of materials,  each of which is either
a low-solids or low-HAP material.  In addition,  an option has
been included in which allowable HAP emissions are calculated
based on the amounts of both types of materials.
     Total volatile matter includes water.   This definition
encourages the substitution of water for organic HAP and also
encourages the substitution of non-HAP organics for organic HAP.
Eliminating water from the definition of total volatile matter
would discourage conversion to waterborne materials.
2.22  COMPLIANCE DEMONSTRATION FOR CATALYTIC OXIDIZERS
     Comment:   Nine commenters stated that outlet temperature is
an inappropriate monitoring parameter for catalytic oxidizers.
Comments IV-D-1 and IV-D-17 (same individual)  stated that testing
                              2-51

-------
at maximum loading which would lead to a high downstream
temperature which would be impossible to comply with under
ordinary conditions.  Commenter IV-D-16 stated that monitoring
inlet and outlet temperatures does not indicate the activity of
the catalyst and merely wastes natural gas.  Commenter IV-D-16
recommended monitoring one temperature and requiring a quarterly
performance test by testing upstream and downstream VOC
concentrations as an alternative to upstream and downstream
temperature measurements.  Commenters IV-D-25, IV-D-36, IV-D-53,
and IV-D-63 stated that temperature rise is not indicative of
performance for catalytic oxidizers.  Commenter IV-D-49 suggested
monitoring inlet and outlet temperature but only maintaining the
inlet temperature.  The outlet temperature would be used to
establish catalyst activity.   Commenter IV-D-51 suggested
monitoring only the exit temperature with a requirement for an
annual catalyst test.
     Commenter IV-D-81 suggested a 20 ppm exit concentration as
an alternative to the 95 percent overall control requirement.
     Response:  The final rule requires the establishment of
temperature upstream of the catalyst as an operating parameter to
ensure compliance with the standard.  The requirement for
monitoring of downstream temperature was eliminated from the
final rule because failure to maintain this parameter during
times of low volatile organic matter flow rate might lead to
exceedances which incorrectly indicate a failure of the control
device.
2.23  CAPTURE EFFICIENCY DETERMINATION
     Comment:  Four commenters (IV-D-1,  IV-D-53, IV-D-54, and
IV-D-84) recommended allowing a test protocol approved by the EPA
in lieu of the procedure specified in §52.741.
     Commenter IV-D-84 suggested allowing demonstration of
capture efficiency by GC analysis every six minutes at the
control device inlet and comparing integrated HAP capture to HAP
use averaging over every one-month period in lieu of a onetime
                               2-52

-------
 test.  Analytical  and flow  rate data were provided as determined
 at  six-minute  intervals  for a period of one month.
     Response:  The  EPA  has clarified the acceptable capture  test
 procedures.  Section 63.828(e) of the final rule specifies that
 the criteria for permanent  total enclosures are to be confirmed
 in accordance  with Procedure T in Appendix B to §52.741.  In  all
 other situations capture efficiency may be determined in
 accordance with §52.741(a) (4) (iii) (B) .
     The  final rule  also allows the use of alternate capture
 efficiency protocols  and test methods which satisfy the criteria
 of either the  Data Quality  Objective or the Lower Confidence
 Limit approaches as  described in Appendix A of the final rule.
     The Procedures  T, L, G.I, G.2,  F.I and F.2 in §52.741 of
 Part 52 were proposed  in the Federal Register on August 2, 1995
 (60 FR 39297)  for  addition  to 40 CFR 51, Appendix M,  as
Method 204 through Method 204E.  (See Docket Item IV-I-3.)
Methods 204 through  204E correspond to Procedures T,  L,  G.I, G.2,
F.I, and F.2 respectively.  There are some differences between
the test methods proposed on August 2,  1995 and the procedures in
§52.741 of Part 52.  A new method,  Method 204F, was also included
in the August 2,  1995 proposal.  The changes and the new method
are summarized below.
     First,  Section  1.4, Sampling requirements, of procedures L,
G.I, G.2,  F.I,  and F.2 contains a requirement that the sampling
time for each temporary total enclosure (TTE)  and building
enclosure (BE)  test run should be at least eight hours,  unless
otherwise approved.  This provision has been revised in the
proposed Methods 204A through 204E to specify that each TTE or BE
run shall cover at least one complete production cycle and must
be at least three hours long.  The sampling time for each run
need not exceed eight hours, even if the production cycle has not
been completed.  The maximum allowable time for a test run is
24 hours.   Alternative sampling times would be subject to EPA
approval.
                               2-53

-------
     Second, a new section on audit sample procedures has been
added to the proposed Method 204A, VOC Input.
     Third, the directions for analysis audits have been expanded
(newly added for Method 204A) to include information on audit
sample availability and reporting directions for audit results.
     Next, Method 204, Criteria for and Verification of a
Permanent or Temporary Total Enclosure, and Method 204E, VOC
Emissions in Fugitive Stream from Building Enclosures, clarify
the acceptability criteria of a BE and clarify which openings in
a building constitute an exhaust point or a natural draft
opening.
     Finally, a new method. Method 204F (called the distillation
approach), has been added for measuring liquid VOC input, as an
alternative to Method 204A.
     Although the Procedures L,  G.I,  G.2,  F.I,  and F.2 in §52.741
of Part 52; and the Methods 204A through 204F  proposed for
addition to 40 CFR 51, Appendix M were developed for TTE and BE
testing, the same procedures and methods can also be used in an
alternative capture efficiency protocol.  For  example, a
traditional liquid/gas mass balance capture efficiency protocol
could employ Procedure L,  proposed Method 204A or proposed Method
204F to measure liquid VOC input and Procedure G.I, or proposed
Method 204B to measure captured VOC.
     Additional guidance on capture efficiency testing procedures
is available in the document "Guidelines for Determining Capture
Efficiency"  (Docket Item II-B-3).   The proposed Methods 204 and
204A through 204F are discussed in this document.
     In addition, other test methods may be used subject to
approval in accordance with the General Provisions, §63.7 (f) .
2.24  STARTUP/SHUTDOWN ISSUES
     Comment:  Commenter IV-D-1 recommended that data collected
during startup and shutdown be disregarded in  determining
continuous compliance.  Commenter IV-D-36 stated that there are
no emissions expected during startup or shutdown, therefore, only
malfunctions should be addressed and that recordkeeping should
                              2-54

-------
 only be  required  of  planned shutdowns of control devices and
 fnalfunctions of control devices.
     Response:  The  required startup, shutdown and malfunction
 plan must  address procedures to be followed during startup,
 shutdown,  and periods of malfunctioning capture or control
 systems.   In cases where the procedures followed are consistent
 with those given  in  the startup, shutdown, and malfunction plan,
 no reporting is necessary.  The EPA does not agree that there are
 no emissions associated with periods of startup and shutdown.  As
 an example, there is a risk of residual organic HAP in ink
 fountains  and ductwork escaping directly to the atmosphere or
 through  the control  device during the periods when the control
 device is  being shut down.
     Startup, shutdown, or malfunction of a press or presses need
 not be considered as a startup, shutdown, or malfunction of the
 affected source if the capture system and control device
 continues  to function properly.  The requirements pertaining to
 startup, shutdown, and malfunction plans and reports do not apply
 to affected sources which do not use control devices.
 2.25  RECORDKEEPING
     Comment:  Commenter IV-D-4 suggested that recordkeeping
 requirements should be reduced for flexographers so that the cost
 of recordkeeping is not out of line with the actual benefits.
     Commenter IV-D-25 recommended annual accounting rather than
 12-month rolling averages as this will afford greater flexibility
 for seasonal variations.   Commenter IV-D-25 expects that local
 EPA officials will require all of the recordkeeping applicable to
major sources,  even it the facility does not exceed the major
 source threshold.
     Commenter IV-D-36 suggested clarifying that specific
 recordkeeping requirements are applicable to the control strategy
employed and all facilities are not required to do all
 recordkeeping.   Commenter IV-D-36 also requested inclusion of a
provision  for recordkeeping under a State-approved operating
permit which would eliminate the required materials inventory.
                               2-55

-------
Commenter IV-D-88 suggested delegating recordkeeping requirement
approval to the permitting authority.
     Two comments were received concerning record retention.
Commenter IV-D-39 recommended that records should be retained for
two years or until the next inspection, whichever is longer.
Commenter IV-D-79 recommended requiring records to be maintained
for five years or until six months after a compliance audit or
inspection.
     Commenter IV-D-79 suggested that HAP usage recordkeeping
should not be required until two years after promulgation.
     Commenter IV-D-81 suggested eliminating recordkeeping
requirements for startup, shutdown, and malfunction events except
when*the plan was not followed and excess emissions occurred as a
result.  Commenter IV-D-81 recommended that if a source was
within the defined operating range for a 24 hour period,  than no
records other than a notation of "no excursions" should be
required.  Commenter IV-D-81 also suggested allowing manual
recordkeeping and permitting readings to be made every four hours
for devices which normally operate at steady state.
     Response:   Recordkeeping requirements for wide-web
flexographic printing sources are equivalent to those for product
and packaging rotogravure sources or sources that operate both
types of equipment.   While flexographic printing,  in general,
uses less organic HAP than rotogravure printing, the organic HAP
emitted from flexography are no less hazardous and no more
difficult to account for than an equivalent amount of organic HAP
emissions from rotogravure.
     Sources taking advantage of the simplified requirements in
§63.820(a)(2)  or §63.821(b) must keep monthly records to
establish eligibility for these provisions.  Recordkeeping on an
annual basis might permit violations to exist for as long as
eleven months.
     The States have the authority to require additional
recordkeeping if they believe it is necessary.  The final
regulation prescribes the minimum recordkeeping requirements that
                               2-56

-------
 the  EPA believes  are necessary to  ensure  that  sources are
 complying with the  rule.   If  recordkeeping  requirements  to
 satisfy State  permits include all  recordkeeping needed to comply
 with the final rule,  these records will be  adequate.  The final
 rule makes it  clear that a source  is responsible for only those
 recordkeeping  requirements applicable to  the compliance  option
 selected by the source.  Additional notes have been added to
 Table 1,  clarifying the applicable General  Provisions.
      Section 63.20(b)  of the  General Provisions requires
 facilities to  maintain all records, including all reports and
 notifications,  for  at  least five years.  The requirement that
 records be retained for five  years is based on the statute of
 limitations imposed on the EPA in  the GAA and is consistent with
 the  requirement in  other rules, such as the Operating Permits
 Rule--Part 70  of Title 40  of  the Code of Federal Regulations.
      The  final  rule  has been  revised to eliminate the requirement
 for  existing sources to provide HAP usage data for the 12 months
 prior  to  the Initial Notification.   This is not required by the
 General  Provisions.  By initial notification, sources will alert
 the permitting authority that  they are major sources, or that
 they are  using the provisions  of the rule to establish area
 source  status.   The  information required by the General
 Provisions  is sufficient.
     The  General Provisions,  §63.10(b)(v)  requires that all
 information necessary to demonstrate compliance with the startup,
 shutdown,  and malfunction plan be maintained.  This information
 may be  recorded using a checklist,  or some other effective form
 of recordkeeping,  in order to minimize the recordkeeping burden
 for conforming events.
     Records of operating parameter values (e.g.,  charts or
 printouts) must be maintained to demonstrate compliance.   The EPA
 has determined that three hours is  an appropriate averaging
period  for operating parameter averaging which will allow for
brief transients when equipment is  started up or shutdown.
                              2-57

-------
Devices that normally operate at steady state may not operate at
steady state during periods of malfunction.
2.26  PRINTING/COATING ISSUES
     Comment:  Two comments were received with regard to small
amounts of printing conducted on coating lines.
Commenter IV-D-16 requested exemptions for sources regulated as
coil coaters and paper and other web coaters that do small
amounts of printing.  They recommend exempting printing
operations that do not exceed major source thresholds and present
a health risk of less than 1 X 1CT6.  These operations would be
covered under the appropriate NESHAP when it is developed.
Commenter IV-D-61 requested exemption of facilities with small
amounts of printing conducted on coating lines because the
database on which the standard was developed did not include this
type of facility.  Commenter IV-D-61 recommended following
California South Coast Air Quality Management Division (SCAQMD)
Rules 1128 and 1130.
     Commenter IV-D-80 recommended a specific exemption for paper
machines and off-line and stand-alone coaters.  Commenter IV-D-80
also requested an exemption for hybrid lines that sometimes print
and sometimes coat,  or alternately, an exemption for coating
operations conducted on hybrid lines.
     Commenter IV-D-53 requested clarification of whether
printing conducted on coating lines is covered by the standard.
Commenters IV-D-36 and IV-D-53 requested clarification of whether
flexo printing on a coating line is included.
     Commenter IV-D-51 suggested that off-line coaters using a
common solvent recovery system should be covered at the
discretion of the facility and that in-line coaters that use
dissimilar solvents should not be covered unless connected to a
common control system with printing stations.
     Commenter IV-D-4 stated that it is inappropriate to regulate
in-line coating under the printing standard.
     Response:  The final standard permits the owner or operator
of a product and packaging rotogravure or wide-web
                               2-58

-------
 flexographic printing  affected  source to choose to exclude
 ancillary printing  equipment  from the affected source.  This
 equipment is used primarily for coating, laminating, or other
 operations besides  product and  packaging rotogravure and wide-web
 flexographic printing.  Presses on which five weight-percent or
 less of the total material applied each month is applied by
 rotogravure or wide-web flexographic print stations would be
 subject only to a simplified  recordkeeping requirement.  The EPA
 believes it is appropriate to provide the owner or operator with
 the option not to subject these presses to the HAP emission
 limitations for product and packaging and wide-web flexographic
 printing in §63.825 because the work being done on the
 rotogravure and wide-web flexographic print stations on these
 presses is ancillary to the work being done on other work
 stations (i.e., coating stations)  on these presses.  The EPA is
 separately establishing MACT  for other source categories,  such as
 the paper and other web coating source category and the metal
 coil coating source category,  which may be more appropriate for
 this type of equipment.  Ancillary printing equipment,  if
 excluded from this standard,  will be subject to the appropriate
 source category standard when such a standard is issued.   Coil
 coaters, paper and other web  coaters, and paper machines may use
 this option and comply with the appropriate NESHAP for their
 source category when promulgated.
     The EPA considers that exclusions based on health risk are
 inappropriate for a technology based standard.
     California SCAQMD Rules  1128  and 1130 provide that coating
 is exempted from other rules  (e.g.,  printing rules).   Inclusion
 of a provision of this type in the final rule is not appropriate
 because a MACT standard for coating has not yet been promulgated.
 Provisions have been added to the  final rule to exempt  incidental
printing operations on coating equipment from all requirements
except simplified recordkeeping provisions.
     The standard applies equally  to product and packaging
rotogravure and wide-web flexographic printing.   Printing
                              2-59

-------
conducted on coating lines is covered by the standard, although
many of these lines may be eligible for the exclusions described
above.  Off-line and stand-alone coaters, on which rotogravure or
wide-web flexographic printing operations are not conducted, are
not covered by the standard  (except in some circumstances when
this equipment is eligible for inclusion at the owner or
operator's option).  Coating operations conducted in-line with
rotogravure and wide-web flexographic printing operations are
covered by the standard because of the difficulty, in
distinguishing capture and control efficiencies applicable to
printing operations from those pertaining to coating operations.
These operations are covered to prevent situations where the same
equipment is subject to more than one standard.
2.27  STANDARD FOR LITHO AND HEATSET PRINTING
     Comment:   Commenter IV-D-14 has experience that petroleum
distillate oil used in litho and heatset inks may contain up to
20 percent HAP and requests that these processes be regulated.
     Response:  Lithographic and letterpress inks are formulated
with petroleum and vegetable oils which have a minimum boiling
point substantially higher than that of any of the organic HAP
present in petroleum oils (such as benzene,  toluene,  xylene,
ethylbenzene,  or hexane),  and thus contain little or no HAP.  The
commenter's experience is not typical.
2.28  UNITS
     Comment:   Four commenters requested changes to the way the
materials are accounted for with regard to the low-HAP threshold.
Commenter IV-D-14 stated that pounds HAP per gallon of material
is preferable to kg HAP per kg solids because that is the way
that the printing industry buys and measures ink.  Also,  weight
units (Ib)  are preferable to mass (kg) because correction for
gravitational constants are eliminated.  Commenter IV-D-37
requested a standard in "grams per liter of material less water
and exempt compounds" to make this consistent with State
standards and avoid the difficulty of complying with two sets of
standards.   Commenter IV-D-39 requested a standard in pounds per
                               2-60

-------
gallon of material, grams per liter of material and percent by
Volume, in addition to kg HAP per kg solids and kg HAP per kg
material as proposed.  Commenter IV-D-79 requested mass/volume
units instead of mass/mass units in expressing the low-solids
standard.
     Commenter IV-D-15 suggested eliminating units from the mass
ratios and replacing the constant coefficient in Equation 13 of
the proposed rule  (for performance testing) with a generic
coefficient to adjust for different combinations of units which
may be used.
     Commenter IV-D-4 requested the use of English units as
printers are familiar with them.
     Response:  The inclusion of standards based on mass per
volume (pounds per gallon,  grams per liter, etc.)  units would
have the effect of discouraging the use of high solids ink
formulations, and encouraging the use of additional dilution
solvents.  The use of additional dilution solvents might increase
organic HAP usage and is likely to increase energy requirements.
     This standard limits emissions of HAP.  Existing State
standards defining "compliant materials" in terms of mass per
volume or mass per volume less water control emissions of VOC
which is a much broader category than organic HAP.
     Material compositions specified in kg per kg are equivalent
to those specified in pound per pound.   Sources may use either
set of units for material compositions.  The equation given for
control device efficiency testing is consistent with the
variables as defined in §63.822.  Sources conducting performance
tests may use the appropriate conversion factors to calculate the
coefficient which is consistent with their test data.
2.29  GLYCOL ETHERS
     Comment:  Commenters IV-D-36 and IV-D-63 requested explicit
definition of glycol ether HAP by CAS number rather than the
structural definition in the CAA.
     Response,:   The definition in the CAA provides explicit
guidance as to whether or not a particular compound is a HAP.  In
                              2-61

-------
theory, many chemical compounds could fit within this definition.
Only a limited number of these compounds are presently in use in
the printing industry, however, a relaxation of the standard
resulting from explicit designation of these compounds might
encourage a shift to other compounds which are HAP as defined in
the CAA.  Propylene glycol ethers, butylene glycol ethers, and
pentylene glycol ethers are not HAP, because they do not fit the
description in §112(b) of the CAA.
2.30  SUMMARY TABLE IN REGULATION
     Comment:  Commenter IV-D-15 recommended eliminating the
Summary Table (Table 1}  or adding a disclaimer that it is not
intended as a substitute for the rule, to avoid misinterpretation
of the abbreviated provisions.
     Response:  Table 1 of the proposed rule has been eliminated
from the final rule.
2.31  GENERAL PROVISIONS CROSS REFERENCE TABLE
     Comment:  Three commenters requested additional
clarifications to the General Provisions cross reference table.
Commenter IV-D-15 recommended noting that not all provisions are
applicable to every affected source and including notes exempting
sources with Part 70 permits from requirements in §63.5 for
Federal approval.
     Commenters IV-D-36  and IV-D-53 requested clarifying notes in
additional table entries indicating that COMS are not required.
Commenter IV-D-53 requested eliminating startup and shutdown from
the startup, shutdown, malfunction plan and just requiring a"'
malfunction plan because emissions are zero or negligible during
startup and shutdown.
     Response:  The applicability of the General Provisions is
summarized in Table 1 of the final regulation.  Additional
clarifying notes have been added to clarify that continuous
opacity monitoring systems are not required.  Explicit
requirements for monitoring, performance testing, reporting and
recordkeeping which are  applicable to particular compliance
strategies are given in the regulation.
                               2-62

-------
      Sources with Part  70  permits must  comply with  §63.5 by
 obtaining the approval  from  the permitting authority.  A startup,
 shutdown,  and malfunction  plan is required of all sources
 operating control devices.   The EPA believes that there is a
 potential for HAP emissions  during the  startup and  shutdown of
 capture  systems and  control  devices.
 2.32  VALIDITY OF COST ANALYSIS
      Comment:  Five  comments were received regarding the accuracy
 of the cost  analysis.  Commenter IV-D-16 stated that the cost
 analysis is  invalid  because  it did not  include coil coaters that
 do incidental  printing.  Commenter IV-D-36 stated that the costs
 presented are  underestimated because facilities with potential to
 emit  will  have to conduct  costly Method 311 analyses.to
 demonstrate  area  source status.  Commenter IV-D-51 stated that
 costs have been underestimated due to failure to consider the
 costs of enhanced monitoring and the costs of accounting to
 confirm  area source  status.  Commenter  IV-D-53 stated that the
 costs and  the  number of affected facilities have been
 underestimated. Commenter  IV-D-40 stated that costs have been
 underestimated by  at least an order of magnitude.
      Response:  Costs presented in the proposal preamble and BID
 were  estimates based on the best information available to the
 EPA.   The  accuracy is limited by uncertainty regarding the number
 of facilities which will establish area source status in
 accordance with the mechanism provided in the final rule or other
 available mechanisms, as well as uncertainty regarding the "
particular compliance strategy which will be adopted by affected
 sources.
     The final rule includes a provision in §63.821(a)(2)(ii)  by
which coil coaters that conduct incidental printing operations
can be excluded from the affected source.   Owners or operators of
such equipment are subject only to simplified recordkeeping
requirements to establish that they meet the criteria for
exclusion.
                              2-63

-------
     The final rule includes alternatives to Method 311 analyses.
Facilities may establish area source status on the basis of
accurate formulation data obtained from their materials
suppliers.
2.33  INTERCHANGEABILITY OF INK SYSTEMS
     Comment:  Two comments were received regarding the
interchangeability of solvent and waterborne inks.
Commenter IV-D-36 stated that solvent and waterborne inks may be
interchangeable on some press stations.  Commenter IV-D-50 stated
that much of the existing equipment in many facilities is
incompatible with waterborne materials.
     Response:   The extent of interchangeability of ink systems
varies depending on printing technology,  equipment, and
substrate.  In general,  rotogravure cylinders for solvent based
and waterborne applications are not interchangeable.  Some
presses lack adequate drying capacity to operate with waterborne
materials.
2.34  STATE AIR TOXICS PROGRAMS
     Comment:  Two comments were received on the relationship
between State and Federal Air Toxics Programs.   Commenter IV-D-36
requested either elimination of, or a moratorium on, State Air
Toxics Programs to eliminate redundancy.   Commenter IV-D-63
prefers State risk-based air toxics programs and recommended the
EPA work with States to develop combined non-duplicative
regulations.
     Response:   Section 112(d)(7)  of the CAA provides that MACT
standards shall not be interpreted to replace standards issued
under State authority.
2.35  ALTERNATE TEST METHODS
     Comment:  Commenters IV-D-39 and IV-D-54 requested that
approval for alternate test methods be delegated to the States.
     Response:   The specification of test procedure is an
integral component of the emission standard.  Allowing States to
approve different test methods might have the effect of
                              2-64

-------
 implementing standards which are  less  stringent  than  the  MACT
 floor.
 2.36  WORK PRACTICE STANDARDS
      Comment:   Commenters  IV-D-39  and  IV-D-79  request inclusion
 of  work  practice  standards  such as keeping  ink and  clean-up
 material container  lids closed when not  in  use.
      Response:  The EPA does not have  sufficient  information  to
 include  this requirement.   Individual  permitting  authorities  may
 require  work practice  standards as a condition in operating
 permits  where appropriate.
 2.37  INNOVATIVE  TECHNOLOGIES
      Comment:   Commenter IV-D-40 requested  provisions for using
 innovative technologies such as biological  treatment  and  allowing
 for delayed compliance  if the innovative technologies do  not
 succeed.
      Response:  The standard allows three years for existing
 sources  to comply.   Provisions for requesting  an  extension of
 compliance are  given in the  General Provisions, §63.7(i).
 2.38  DUE  PROCESS
      Comment:   Commenter IV-D-61 stated that sources  conducting
 incidental printing operations will not have the  opportunity  to
 comment  on the  proposal because they will not  know that they  are
 covered, particularly since  the regulatory  text is not published.
 Commenter  IV-D-81 stated that the  EPA must print  the proposed
 regulation and  cites difficulty with conversion of bulletin board
 versions of  the regulation to Microsoft WORD or WordPerfect "6.1.
      Response:  The preamble  stated that "The proposed rule
 addresses  facilities which apply ink and other materials  to any
 substrate,  except fabric, using rotogravure or wide-web
 flexographic methods."  This definition encompasses all
 facilities  affected by the regulation.
      The proposed regulatory text was available for public
 inspection and  copying in the Air and Radiation Docket at the
 time  of proposal.    In addition,  printed copies were available by
written or  telephone request to the Air and Radiation Docket.
                              2-65

-------
The EPA considers that the 75-day period allowed for public
comments included sufficient time for commenters who were unable
to make use of the electronic version of the regulatory text to
obtain a printed copy.
2.39  EXEMPTION FOR NEWLY LISTED HAP
     Comment:  Commenter IV-D-80 stated that the rule should not
apply to new solvents added to the HAP list after proposal of the
standard.
     Response:   The EPA believes that the standards in
§§63.824-825 apply to those organic HAP listed pursuant to
§112(b) of the CAA as of the date of proposal (and not
subsequently deleted).  The suitability of the available capture
and control technologies considered in determining MACT would be
evaluated before extending the standard to newly listed HAP.
2.40  FEASIBILITY OF MATERIALS SUBSTITUTION
     Comment:  Commenter IV-D-4 stated that glycols on the HAP
list can be easily replaced with non-HAP materials.
     Response:   The ease of replacement of glycols and glycol
ethers on the HAP list is expected to vary depending on the
printing technology,  substrate, and performance requirements of
the printed material.  The final regulation provides a
significant incentive to encourage pollution prevention through
replacement of  HAP with non-HAP materials.
