Effective 5 April 1982 Last Amended 8 April 1996 AIR POLLUTION CONTROL REGULATION NO. 21 CONTROL OF VOLATILE ORGANIC COMPOUND EMISSIONS FROM PRINTING OPERATIONS 21-1 RHODE ISLAND DEPARTMENT OF ENVIRONMENTAL MANAGEMENT DIVISION OF AIR RESOURCES AIR POLLUTION CONTROL REGULATION NO. 21 CONTROL OF VOLATILE ORGANIC COMPOUND EMISSIONS FROM PRINTING OPERATIONS 21 Control of Volatile Organic Compound Emissions from Printing Operations 21.1 Definitions The following terms shall, where the context permits, be construed as follows: 21.1.1 "Volatile organic compound" (VOC) means any organic compound which participates in atmospheric photochemical reactions. This includes any organic compound other than the following compounds: (a) acetone (b) CFC-11 (trichlorofluoromethane) (c) CFC-12 (dichlorodifluoromethane) (d) CFC-113 (1,1,1-trichloro 2,2,2-trifluoroethane) (e) CFC-114 (1,2-dichloro 1,1,2,2-tetrafluoroethane) (f) CFC-115 (chloropentafluoroethane) (g) ethane (h) HCFC-22 (chlorodifluoromethane) (i) HCFC-123 (1,1,1-trifluoro 2,2-dichloroethane) (j) HCFC-124 (2-chloro 1,1,1,2-tetrafluoroethane) (k) HCFC-141b (1,1-dichloro 1-fluoroethane) (l) HCFC-142b (1-chloro 1,1-difluoroethane) (m) HFC-23 (trifluoromethane) (n) HFC-125 (pentafluoroethane) (o) HFC-134 (1,1,2,2-tetrafluoroethane) (p) HFC-134a (1,1,1,2-tetrafluoroethane) (q) HFC-143a (1,1,1-trifluoroethane) (r) HFC-152a (1,1-difluoroethane) (s) methane (t) methyl chloroform (1,1,1-trichloroethane) (u) methylene chloride (dichloromethane) (v) parachlorobenzotrifluoride (PCBTF) 21-2 (w) cyclic, branched, or linear completely methylated siloxanes (x) The perfluorocarbon compounds which fall into these classes: (1) Cyclic, branched, or linear, completely fluorinated alkanes; (2) Cyclic, branched, or linear, completely fluorinated ethers with no unsaturations; (3) Cyclic, branched, or linear, completely fluorinated tertiary amines with no unsaturations; and (4) Sulfur containing perfluorocarbons with no unsaturations and with sulfur bonds only to carbon and fluorine. These compounds have been determined to have negligible photochemical reactivity. For purposes of determining compliance with emission limits, VOC will be measured by the approved test methods. Where such a method also inadvertently measures compounds with negligible photochemical reactivity, as defined above, an owner or operator may exclude these negligible photochemical reactive compounds when determining compliance with an emissions standard. Exempt solvents will be treated as water in "pounds of VOC per gallon of coating minus water" calculations. Classification of methylene chloride as an exempt compound does not relieve the facility of the requirements in Air Pollution Control Regulation No. 22. 21.1.2 "Halogenated Organic Compound" and "HOC" means the following compounds: (a) CFC-11 (trichlorofluoromethane) (b) CFC-12 (dichlorodifluoromethane) (c) CFC-113 (1,1,1-trichloro 2,2,2-trifluoroethane) (d) CFC-114 (1,2-dichloro 1,1,2,2-tetrafluoroethane) (e) CFC-115 (chloropentafluoroethane) (f) HCFC-22 (chlorodifluoromethane) (g) HCFC-123 (1,1,1-trifluoro 2,2-dichloroethane) (h) HCFC-124 (2-chloro 1,1,1,2-tetrafluoroethane) (i) HCFC-141b (1,1-dichloro 1-fluoroethane) (j) HCFC-142b (1-chloro 1,1-difluoroethane) (k) methyl chloroform (1,1,1-trichloroethane) (l) methylene chloride (dichloromethane) 21.1.3 "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 21-3 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. 21.1.4 "Enforceable Document" is a permit issued under the requirements of Air Pollution Control Regulation Number 9, an approval issued under this regulation, or a consent agreement. 21.1.5 "Facility" means all pollutant emitting activities located in a building or buildings on one or more adjacent properties owned or operated by the same person. 21.1.6 "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. 21.1.7 "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. 21.1.8 "Person" means an individual, trust, firm, joint stock company, corporation (including a quasi-governmental corporation), partnership, association, syndicate, municipality, municipal or state agency, fire district, club, non-profit agency or any subdivision, commission, department, bureau, agency or department of state or federal government (including quasi-governmental corporation) or of any interstate body. 21.1.9 "Potential Emissions" means the maximum capacity of a stationary source to emit a pollutant under its physical or operational design unless limited by the conditions of a federally enforceable document. 21.1.10 "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. 21.1.11 "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. 21-4 21.1.12 "Reasonably Available Control Technology" (RACT) means the lowest emission limitation that a particular printing press is capable of meeting by using measures that are reasonably available in terms of technological and economic feasibility. Such measures may include either control system(s) or ink reformulation(s) or both. 21.1.13 "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. 21.1.14 "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. 21.1.15 "Specialty printing" means all other rotogravure and flexographic printing operations, excluding publication printing and packaging printing. 21.2 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: (a) Actual annual emissions shall not exceed 50 tons VOC per year; and (b) 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. 21-5 Recordkeeping to demonstrate compliance will follow the guidelines in Section 21.7. 21.3 Emission Limitations 21.3.1 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: (a) 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 (b) 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 (c) 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 (d) 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. 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 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: (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 21.3.1 must show that the equipment meets specific capture and control performance standards which will be set in 21-6 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: Compliance Method EPA Reference Test Method Test Averaging Time Reformulation 24 instantaneous Solvent destruction or solvent recovery except carbon adsorption 25 3 hours 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. 21-7 21.4 Compliance Schedule 21.4.1 (a) The owner or operator of a rotogravure or flexographic printing facility subject to this regulation shall achieve compliance with the emission limitations in Section 21.3 according to the dates in Subsections 21.4.2 and 21.4.3, and shall submit in writing proposed plans and compliance schedules described in Subsections 21.4.4 (a) and 21.4.4 (b) to the Director for approval no later than the dates listed in Subsection 21.4.4 (c).

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 (d) 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. 21.4.7 (a) The compliance schedule shall not allow a printing press to supersede any applicable emission limitations required by the Director but not limited to: (1) Best Available Control Technology determinations, or (2) Lowest Achievable Emissions Rate determinations, or (3) Federal New Source Performance Standards, or (4) National Emission Standards of Hazardous Air Pollutants, or (5) Any other condition or standard that is specifically required by the Clean Air Act (as amended) for new or modified sources. (6) 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" 21-11 Concept) 21.5.1 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. 21.5.2 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) A description of the printing presses which will not comply with the emission limitations, (b) 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, (c) 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), (d) 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 (e) A description of the procedures and methods used to determine the emissions of volatile organic ccompounds. (f) 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. (g) 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 21-12 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. (h) 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. 21.5.3 The facility-wide emission reduction plan cannot include decreases in emissions resulting from other regulations that have been promulgated by the Director. 21.5.4 The facility-wide emission reduction plan shall be fully implemented within two years of approval by the Director. 21.5.5 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. 21.5.6 All compliance schedules based on the provisions of this section shall be subject to all the conditions of Subsection 21.4.6. 21.5.7 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. 21-13 21.5.8 Facilities applying to bubble will be assigned an emission baseline, as described in Subsection 21.1.3. 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 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. (b) Emission reductions must be permanent. The amount and duration of the 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 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. 21.7 Recordkeeping 21.7.1 (a) The facility shall maintain the following information at the facility at all times. 21-14 This information shall be kept current and be made available to the DEM or EPA upon request. 1.
