AIR POLLUTION CONTROL REGULATION NO. 21

CONTROL OF VOLATILE ORGANIC COMPOUND EMISSIONS

FROM PRINTING OPERATIONS

21.1	Definitions

Unless otherwise expressly defined in this section, the terms used in
this regulation shall be defined by reference to the Rhode Island Air
Pollution Control General Definitions Regulation.  As used in this
regulation, the following terms shall, where the context permits, be
construed as follows:

21.1. 1 “Emission Baseline” means a level of emissions calculated by
multiplying two factors:

		(a)	the lowest of the source’s actual or allowable emission rate in
emissions per unit of production; and

		(b)	the source’s actual capacity utilization, or units of
production, over some representative time period.  Generally, the time
period is the preceding two years unless the source can demonstrate that
those years were not representative of historical production.

21.1.2	“Flexographic printing” means the application of words,
designs and/or pictures to a substrate by means of a roll-printing
technique in which the pattern to be applied is raised above the
printing roll and the image carrier is made of rubber or other
elastomeric materials.

21.1.3	“Packaging rotogravure printing” means rotogravure printing
upon paper, paper board, metal foil, plastic film or other substrates,
and other substrates, which are, in subsequent operations, formed into
packaging products and labels for articles to be sold.

21.1.4	“Printing press” means equipment used to apply words,
pictures, or graphic designs to either a continuous substrate or a
sheet.  A continuous substrate consists of paper, plastic, or other
material that is unwound from a roll, passed through coating or ink
applicators and any associated drying areas.  The press includes all
coating and ink applicators and drying areas between unwind and rewind
of the continuous substrate.  A sheet consists of paper, plastic, or
other material that is carried through the process on a moving belt. 
The press includes all coating and ink applicators and drying operations
between the time that the sheet is put on the moving belt until it is
taken off.

21.1.5	"Publication rotogravure printing" means rotogravure printing
upon paper which is subsequently formed into books, magazines,
catalogues, brochures, directories, newspaper supplements, or and other
types of printed materials.

21.1.6	”Roll printing” means the application of words, designs
and/or pictures to a substrate by means of a series of hard rubber or
steel rolls each with only partial coverage.

21.1.7	“Rotogravure printing” means the application of words,
designs and/or pictures to a substrate by means of a roll-printing
technique, in which the pattern to be applied by the printing roll is
accomplished by an intaglio or recessed image areas in the form of
cells.

21.1.8	"Specialty printing" means all other rotogravure and flexographic
printing operations, excluding publication printing and packaging
printing.

Applicability

21.2.1	This regulation applies to all roll, specialty, rotogravure, and
flexographic printing facilities whose potential to emit volatile
organic compounds from printing operations is or ever has been, equal to
or greater than 50 tons/year. Printing operations include but are not
limited to printing, drying, mixing and any other functions associated
with printing.

	21.2.2	This regulation does not apply to any equipment in a facility
used exclusively for chemical or physical analysis or determination of
product quality and commercial acceptance provided that the operation of
the equipment is not an integral part of the production process and the
total actual emissions from all such equipment at the facility do not
exceed 204 kilograms (kg) (450 pounds (lb)) in any calendar month.

	21.2.3	Where ever the term "Volatile Organic Compound" or "VOC" is used
in Sections 21.2 through 21.7, this term should be read as "Volatile
Organic Compound and Halogenated Organic Compound" or "VOC and HOC".

	21.2.4	Sources with potential yearly emissions of 50 tons or more of
VOC, but with actual emissions not exceeding 50 tons/year VOC since 1
January 1990, may apply to the Director for exemption from this
regulation.  Exemption from this regulation will be given in the form of
an enforceable document, and will include the following conditions:

Actual annual emissions shall not exceed 50 tons VOC per year; and 

The facility will meet the emission cap every consecutive 12 month
period or on another more stringent schedule approved as enforceable by
the Director.   The cap must be consistent with the anticipated level of
emissions in the approved SIP.  Recordkeeping to demonstrate compliance
will follow the guidelines in Section 21.7.

21.3	Emission Limitations

No owner or operator of a rotogravure, flexographic, or specialty
printing facility subject to this regulation and employing
solvent-containing ink may operate, cause, allow or permit the operation
of the facility unless one of the following is complied with at all
times:

the volatile fraction of ink, as it is applied to the substrate,
contains not more than 25.0 percent by volume of organic solvent and not
less than 75.0 percent by volume of water, or

the ink as it is applied to the substrate, less water, contains not less
than 60.0 percent by volume of nonvolatile material (solids), or

the installation of one or more approved volatile organic compound
control device(s), as limited by Subsections 21.3.2 and 21.3.3, is
certified to achieve at least a 90 percent reduction efficiency as
measured across each control device, or

an alternative measure is employed which has been demonstrated to the
satisfaction of the Director to have a volatile organic compound
emission reduction at least equivalent to an amount potentially achieved
by Subsections 21.3.1 (a) or (b).  All alternative measures must be
submitted for EPA approval as a source-specific SIP revision.

A capture system must be used in conjunction with the emission control
devices installed per Subsection 21.3.1 (c).  The design and operation
of a capture system must be consistent with good engineering practice,
and, in conjunction with the control device, must provide for an overall
reduction in volatile organic compound emissions at each printing press
of at least:

75.0 percent where publication rotogravure printing process is employed,
or

65.0 percent where packaging rotogravure printing process or specialty
printing process is employed, or

60.0 percent where flexographic printing process is employed.

	Facilities using add on controls to comply with Subsection 21.3.1 must
show that the equipment meets specific capture and control performance
standards which will be set in an enforceable document.

	Control device efficiency will be determined using EPA-approved test
methods.  Calculations will be done on a solids applied basis. 
Continuous compliance will be maintained at all times.  Compliance
averaging times will be met according to the control device chosen and
EPA test methods (as codified in 40 CFR 60), as follows:

 PRIVATE  Compliance Method	EPA Reference Test Method	Test Averaging
Time



 PRIVATE  Reformulation	24	instantaneous



 PRIVATE  Solvent destruction or solvent recovery except carbon
adsorption	25	3 hours



 PRIVATE  Carbon adsorption	25 or other test method as appropriate	7 day
rolling average



	or other methods approved by the Director and EPA.  Once the control
efficiency has been determined for any add-on control device by
Reference Method 25, or any alternative method approved by the
Department and EPA, compliance shall be determined on an instantaneous
basis (e.g. determined control efficiency shall be used to calculate
whether samples from the process meet the applicable emissions limit.)

	The owner or operator of a facility using carbon adsorption as a
control measure shall obtain data on daily solvent usage and solvent
recovery and determine the solvent recovery efficiency of the system
every day.  The recovery efficiency for each day shall be computed as
the ratio of the total recovered solvent for that day and the prior six
consecutive operating days to the total solvent usage for the same seven
day period.  This ratio shall be expressed as a percentage.  Facilities
may apply to the Director for an alternative averaging time if meeting
the emission limitation as a 7 day rolling average is not technically or
economically feasible.  In no event shall the averaging period exceed a
30-day rolling period.  All alternative averaging periods must be
consistent with EPA guidance.

21.3.3	Control and capture equipment installed per subsections 21.3.1
(c) and 21.3.2 will be incorporated in a permit issued in accordance
with Air Pollution Control Regulation Number 9 or by approval. 
Compliance with the permit or approval will be determined, when
necessary, with DEM and EPA approved test methods.  The permit or
approval will include record keeping and test methods required to
demonstrate compliance.

21.4 	Compliance Schedule

	21.4.1	(a)The owner or operator of a rotogravure or flexographic

21.4.5	The owner or operator of a facility subject to a compliance
schedule by this section shall certify to the Director within five (5)
days after the deadline for each increment of progress as to whether the
required increment of progress has been met, and written documentation
or photocopies of documents shall be included as evidence, whenever
applicable.

21.4.6	The emission limitations of Section 21.3 may be relaxed subject
to the following conditions:

The owner or operator of a facility documents to the satisfaction of the
Director that such emission limitations cannot be met because neither
coating reformulation(s) nor the installation of a control system is
economically or technically feasible or even partially feasible, and

The facility shall provide the Director with the documentation no later
than twelve (12) months after the effective date of this regulation and

The facility shall submit new emission limitations that will represent
an Alternative Reasonably Available Control Technology for approval by
the Director.  Alternative RACT shall also be submitted to EPA as a
source-specific SIP revision.  New emission limitations shall be
achieved within two years of submittal of a SIP revision to EPA; and

The Director shall require the facility to undergo Reasonably Available
Control Technology review every three years thereafter until the
emission limitations of Section 21.3 are achieved.

(a) The compliance schedule shall not allow a printing press to
supersede any applicable emission limitations required by the Director
but not limited to:

Best Available Control Technology determinations, or

Lowest Achievable Emissions Rate determinations, or

Federal New Source Performance Standards, or

National Emission Standards of Hazardous Air Pollutants, or

Any other condition or standard that is specifically required by the
Clean Air Act (as amended) for new or modified sources.

For bubbles issued under Section 21.5, the emission baseline.

		(b)	For compliance schedules allowing bubbles involving volatile
organic compounds identified as hazardous, the provisions of EPA's
bubble policy (51 FR 43814) on pollutant comparability shall apply.

21.5	Alternative Standards Showing Internal Offsets for Printing
Facilities (The "Bubble" Concept)

The Director may approve alternative volatile organic compound emission
standards in applicable compliance schedules if the requirements of
Subsections 21.5.2 through 21.5.9 are met.  The option to meet
requirements of Regulation 21 by bubbling is not available if the
Federal Environmental Protection Agency has designated Rhode Island as a
Non-Attainment Area for Ozone and the area is lacking an approved
demonstration of attainment (NALAD).  Bubbles approved when the state is
under other designations shall remain in force when the state is
designated as NALAD for Ozone.

The facility demonstrates, by means of approved material balance or a
DEM and EPA-acceptable emission test, that sufficient reductions in
volatile organic compound emissions may be obtained by controlling other
existing printing presses in an amount equivalent to all excess
emissions resulting from one or more printing presses not achieving the
emission limitations of Section 21.3.  Such written demonstration shall
be submitted to the Director and shall include:

A description of the printing presses which will not comply with the
emission limitations,

Pounds per day of volatile organic compounds emitted in excess of
allowable emissions for each printing press.  Nonreactive VOC may not
generate credit in a trade against reactive VOC in a bubble,

A description of all printing presses within the facility with air
cleaning devices, if any, whose emissions, when bubbled, will offset
those from printing presses reported under Subsection 21.5.2(a),

Pounds per day of volatile organic compounds from each printing press
before and after the installation of any air cleaning device and/or a
description of any physical or operational changes at the facility to
reduce emissions and the date on which such reductions will be achieved,
and

A description of the procedures and methods used to determine the
emissions of volatile organic ccompounds.

Demonstration of how compliance will be met on a 24 hour basis. 
Printing facilities utilizing Section 21.5 must demonstrate compliance
with this regulation on a gallons of solids applied basis.

The Department shall not approve any emissions bubble without first
giving public notice at least 30 days prior to approval, and affording
all interested persons opportunity to comment.  The public may request a
hearing.  Upon a demonstration of significant public interest, the
Director, in his discretion, may hold a hearing.  EPA shall be provided
with the public notice, proposed approval order, and technical support
by the first day of the public comment period.  Public (and EPA)
comments will be considered prior to final approval of the bubble
application.  Upon issuance of final approval of the bubble, EPA will be
mailed a copy of the approval, new technical support, and response to
public comments.

The combined actual emission over a 24-hour period from all inks in the
bubble used on printing presses which are part of the graphic arts
facility and which are eligible as per subsection 21.5.9 (a) must be
less than or equal to the allowable emission total (E) determined by the
following equation:

			E = A1 x B1 + A2 x B2 + ... + An x Bn:  

			where

			E= the allowable emissions from the graphic arts facility in pounds
per day;

			A1, A2, ..., An = the applicable emission limitation for each ink
(which for the purposes of Subsection 21.5 shall be 0.5 pounds of
VOC/pound of solids applied); 

			B1, B2 ..., Bn = the pounds of solids applied for each ink in that
24-hour period.

The facility-wide emission reduction plan cannot include decreases in
emissions resulting from other regulations that have been promulgated by
the Director.

The facility-wide emission reduction plan shall be fully implemented
within two years of approval by the Director.

Any emissions in excess of those limits established for each printing
press in any compliance schedule or order issued under this section
shall be a violation.

All compliance schedules based on the provisions of this section shall
be subject to all the conditions of Subsection 21.4.6.

The provisions and emission limitations of any approved bubble shall be
incorporated in an approval.  Compli`ance with this approval will be
determined, when necessary, with EPA approved test methods.  The
approval must include source specific emission limits, recordkeeping
requirements, and test methods used to demonstrate compliance.  A
facility which is subject to an enforcement action needs EPA approval to
bubble. 

Facilities applying to bubble will be assigned an emission baseline, as
described in Subsection 21.1.1  Capacity utilization will be based on
the average production during the two-year period prior to application
to bubble.  The facility's annual emissions may not exceed the limit set
by the emission baseline. Emissions must be reported monthly and
compliance with the emission baseline must be met every consecutive 12
month period, or on a more stringent compliance schedule approved by the
Director.

An approvable bubble must meet the following requirements:

Emissions must be surplus.  The reductions must not have been included
in those anticipated in the State Implementation Plan for the affected
source.  ERC's cannot be taken for reductions made prior to the base
year of the State's Approved SIP.  Emissions reductions shown must not
have been required by current state regulations, and must not be used by
the facility to meet any other regulatory requirement.

Emission reductions must be permanent.  The amount and duration of the
reductions must be shown.

Emission reductions must be quantifiable.  A reliable basis for
calculating the amount and rate of reductions must be used.  Emission
rates before and after the reductions must be shown, and the reductions
described.

Emission reductions must be enforceable.  An approval containing
enforceable emissions rates will be issued.

All of the requirements of EPA's final Emission Trading Policy (51 FR
43814) must be met.

21.6	Compliance Demonstration/Testing

21.6.1	Compliance with applicable sections of this regulation shall be
demonstrated in accordance with 40 CFR 60, Appendix A, Methods 24, 24A,
25 as amended or any other EPA approved method which has been accepted
by the Director and EPA.  A one hour bake time must be used for Methods
24 and 24A and, further, Method 24 and 24A apply to multicomponent
coatings.
