### RHODE ISLAND DEPARTMENT OF ENVIRONMENT AL MANAGEMENT OFFICE OF AIR RESOURCES 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 inthis regulation shall be defined byreference 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 ofemissions calculated by multiplying two factors: (a) the lowest ofthe source's actual or allowable emission rate in emissions perunit ofproduction; and (b) the source's actual capacity utilization, or

### units ofproduction, 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 ofhistorical production. 21.1.2 

### "Flexographic printing" means the application ofwords, designs and/or pictures to a substrate bymeans ofa roll-printing technique in which the pattern to be applied is raised above the printing roll and the image carrier is made ofrubber 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 ofpaper, plastic, or other material that is unwound from a roll, passed through coating orink applicators and any associated drying areas. The press includes all coating and ink applicators and drying areas between unwind and rewind ofthe continuous substrate. A sheet consists ofpaper, 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 Page 1of15sheet isput 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 ofprinted materials. 21.1.6 "Roll printing" means the application ofwords, designs and/or pictures to a substrate by means ofa series ofhard rubber or steel rolls each with only partial coverage. 21.1.7 "Rotogravure printing" means the application ofwords, designs and/or pictures to a substrate bymeans ofa roll-printing technique, 

### in which the pattern to be applied by the printing roll is accomplished by an intaglio or recessed image areas inthe form ofcells. 21.1.8 "Specialty printing" means all other rotogravure and flexograpbic printing operations, excluding publication printing and packaging printing.
21.2 Applicability 21.2.l This regulation applies to all roll, specialty, rotogravure, and flexographic printing facilities whose potential to emit volatile organic compounds from printing operations is orever has been, equal to or greaterthan 50tons/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 orphysical analysis or determination ofproduct quality and commercial acceptance provided that the operation ofthe equipment is not an integral part oftheproduction 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 e1t1er the term "Volatile Organic Compol:Hld" or "VOC" is used in 8ectioJXS 21.2 throtigh 21.7, this tenn shotild be read as "Volatile Orgaaie Compmmd aad Halogenated Organic Compol:Hld" or "VOC and HOC". 21.2.4 Sources with potential yearly emissions of50 tons or more ofVOe, but with actual emissions not exceeding 50 tons/year voe since 1January1990, may apply to the Director for exemption from this regulation
. Exemption from this regulation will be given inthe form ofan enforceable document, and will include the following conditions: (a) Actual annual emissions shall not exceed 50 tons VOe peryear; and Page 2of15(b) The facility will meet the emission cap every consecutive 12 month period or on another more stringent schedule approved as enforceable bythe Director. The cap must be consistent with the anticipated level
.ofemissions inthe approved SIP. Recordkeeping to demonstrate compliance will follow the guidelines in Section 21.7.


### 21.3 Emission Limitations 21.3.l No owner or operator ofa rotogravure, flexographic, or specialty printing facility subject to this regulation and employing solvent-containing ink may operate, cause, allow orpermit the operation ofthe facility unless one ofthe following is complied with at all times: (a) the volatile fraction ofink, as it is applied to the substrate, contains not more than 25.0 percent by volume oforganic solvent and not less than 75.0 percent by volume ofwater, or (b) the ink as it is applied to the substrate, less water, contains not less than 60.0 percent by volume ofnonvolatile material (solids), or (c) the installation ofone 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 (d) an alternative measure is employed which has been demonstrated to the satisfaction ofthe Director to have a volatile organic compound emission reduction at least equivalent to an amount potentially achieved by Subsections 21.3.l (a) or 

### (b). All alternative measures must be submitted for EPA approval as a source-specific SIP revision. 21.3.2 A capture system must be used in conjunction with the emission control devices installed per Subsection 21.3. 1 (c). The design and operation ofa capture system must be consistent With good engineering practice, and, in conjunction with the control device, mustprovide for an overall reduction in volatile organic compound emissions at each printing press ofat least: (a) 75.0 percent where publication rotogravure printing process is employed, or (b) 65.0 percent where packaging rotogravure printing process or specialty printing process is employed, or (c) 60.0 percent where flexographic printing process is employed. Facilities using add on controls to comply with Subsection 21.3.I must show that Page 3of15the equipment meets specific capture and control performance standards which will be set in an enforceable docwnent. 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: Compliance Method
Reformulation Solvent destruction or solvent recovery except carbon adsorption Carbon adsorption EPA Reference Test Method 24 25

25 or other test method as appropriate Test Averaging Time
instantaneous 3 hours

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 bythe 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 car bon adsorption as a control measure shall obtain data on daily solvent usage and solvent recovery and determine the solvent recovery efficiency ofthe system every day
. The recovery efficiency for each day shall be computed as the ratio ofthe 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 ifmeeting the emission limitation as a 7 day rolling average is not technically oreconomically 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.l (c) and 21.3
.2 will be incorporated in a permit issued in accordance with Air Pollution Control Regulation Nwnber 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. Page 4of15

### 21.5 Alternative Standards Showing Internal Offsets for Printing Facilities (The "Bubble" Concept) 21.5.1 The Director may approve alternative volatile organic compound emission standards in applicable compliance schedules ifthe requirements ofSubsections 21.5.2 through 21.5.9 are met. The option to meetrequirements ofRegulation 21 by bubbling is not available ifthe Federal Environmental Protection Agency has designated Rhode Island as a Non

-Attainment Areafor Ozone and the area is lacking an approved demonstration ofattainment (NALAD). Bubbles approved when the state isunder other designations shall remain inforce when the state is designated as NALAD for Ozone. Page 8of1521.5.2 The facility demonstrates, by means ofapproved 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 ofSection 21.3. Such written demonstration shall be submitted to the Director and shall include: (a) A description ofthe printing presses which will not comply with the emission limitations, (b) Pounds per day ofvolatile organic compounds emitted inexcess ofallowable emissions for eachprinting press. Nonreactive 

## voe may not generate credit in a trade against reactive 

## voe in a bubble, (c) A description ofall printing presses within the facility with air cleaning devices, ifany, whose emissions, whenbubbled, will offset those from printing presses reported under Subsection 21.5.2(a), (d) Pounds per day ofvolatile organic compound· s from each printing press before and after the installa tion ofany air cleaning device and/or a description of any physical or operational changes at the facility to reduce emissions and the date on which suchreductions will be achieved, and

· (e) A description ofthe procedures and methods used to determine the emissions of volatile organic ccompounds. (f) Demonstration ofhow compliance will be met on a 24 hour basis. Printing facilities utilizing Section 21.5 must demonstrate compliance with this regulation on a gallons ofs. olids applied basis. (g) The Department shall not approve any emissions bubble without first giving public notice at least 30 days priorto approval, and affording all interested persons opportunity to comment. The public may request a hearing. Upon a demonstration ofsignificant 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 bythe first day ofthe public comment period. Public (and EPA) comments will be conside redprior to final approval ofthe bubble application. Upon issuance offinal approval ofthe bubble, EPA will be mailed a copy ofthe approval, new technical support, andresponse to public comments. (b) The combined actual emission over a 24-hour period from all inks inthe bubble used onprinting presses which are part ofthe 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: Page 9of15E = A 1

..., Bn 

## =the pounds ofsolids applied for each ink inthat 24-hour period. 21.5 .3 The facility-wide emission reduction plan cannot include decreases in emissions resulting from other regulations that have been promulgated by th e Director. 21.5.4 The facility-wide emission reduction plan shall be fully implemented within two years ofapproval by the Director. 21.5.5 Any emissions in excess ofthose limits established for eachprinting press in any compliance schedule or order issued under this section shall be a violation. 21.5.6 All compliance schedules based onthe provisions ofthis section shall be subject to all the conditions ofSubsection 21.4.6. 21.5.7 The provisions and emission limitations ofany 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, record.keeping requirements, and test methods used to demonstrate compliance. A facility which is subject to an enforcement action needs EPA approval to bubble. 21.5.8 Fa cilities 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. 21.5.9 An approvable bubble must meet the following requirements: (a) Emissions mustbe surplus. The reductions must not have been included in those anticipated inthe State Implementat ion Plan for the affected source. Page 10of15ERC's cannot be taken for reductions made priorto the base year ofthe State's Approved SIP. Emissions reductions shown must not have been required by current state regulations, and must not be used bythe facility to meet any other regulatory requirement. (b) Emission reductions must be permanent. The amoun t and duration ofthe reductions must be shown. (c) 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. (d) Emission reductions must be enforceable. An approval containing enforceable emissions rates will be issued. (e) All ofthe requirements ofEPA's final Emission Trading Policy (51 FR 43814) must be met.


### 21.6 Compliance Demonstrationff esting 21.6.1 Compliance with applicable sections ofthis regulation shall be demonstrated in accordance with 40 CPR 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 mustbe used for Methods 24 and 24A and, further, Method 24 and 24A apply to multicomponent coatings.
