**RHODE ISLAND DEPARTMENT OF ENVIRONMENTAL MANAGEMENT OFFICE**  **OF AIR RESOURCES AIR POLLUTION CONTROL REGULATION NO. 21**  **CONTROL OF VOLATILE ORGANIC COMPOUND EMISSIONS**

**F ROM 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 I sland Air Pollution Control General Definitions Regulation. As used in this regul ation, 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 emi ssions

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 ye ars 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 subsequen t 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 pap er, 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 substrat e. A sheet consists of paper, plastic, or other material that is carried through the process on a moving belt. The press includesPage 2 of 1 5 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 ty pes of printed materials. 21.1. 6 **” Rol**  **l 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 flexograph ic 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, dry ing, 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 phy sical analy sis 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 emiss ions 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 "Vol atile Organic Compound and Halogenated Organic Compound" or "VOC and HOC ". 21.2.4 Sources with potential y early 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:Page 3 of 1 5 (a) Actual annual emissions shall not exceed 50 tons VOC per year; and (b) The facility

will mee t 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 SI P. Recordkeeping to demonstrate comp liance 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 perce nt 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 l imited 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 SI P revision. 21.3.2 A capture sy stem must be used in conjunction with the emission control devices installed per Subsection 21.3.1 (c). The design and operation of a capture sy stem 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 proc ess is employ ed, orPage 4 of 1 5 (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 i n 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 pr ocess 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 sy stem every

d ay . 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 day s 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 p eriod. 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 Regulatio n Number 9 or by approval. Compliance with the permit or approvalPage 5 of 1 5 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 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).

to the Director within five (5) day s 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 followingPage 8 of 1 5 conditions: (a) 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 sy stem is economically or technically

feasible or even partially feasible, and (b) The facility

shall provide the Director with the documentation no later than twelve (12) months after the effective date of this regulation and (c) 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 SI P revision. New emission limitations shall be achieved within two ye ars of submittal of a SI P revision to EPA; and (d) The Director shall require the facility to undergo Reasonably

Ava ilable Control Technology

review every

three y ears 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 Direct or but not limited to: (1) Best Available Control Technology determinations, or (2) Lo west Achievable Emissions Rate determinations, or (3) Federal New Source Performance Standards, or (4) National Emission Standards of Hazardous Air Pollutants, or (5) Any other conditio n 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" Concept)** 21.5.1 The Director may approve alternative volatile organic compound emissionPage 9 of 1 5 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 Pr otection Agency has designated Rhode I sland 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 des ignated 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 printin g 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 o f 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 phy sical or operational changes at the facility to reduce emissions and the date on which such reductions will be achieved, and (e) A d escription 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 regu lation on a gallons of solids applied basis. (g) The Department shall not approve any emissions bubble without first giving public notice at least 30 day s 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 perio d. Public (and EPA) comments will be considered prior to final approvalPage 10 of 1 5 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 comb ined 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) d etermined 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 th e 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 resu lting 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 ye ars of approval by

the Director. 21.5.5 Any

emissions in excess of those limits established for each print ing 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, a nd test methods used to demonstrate compliance. A facility which is subject to an enforcement action needs EPA approval to bubble. 21.5.8 Facilities applying to bubble will be assigned an emission baseline, as described in Subsection 21.1. 1 Capacity utilizati on will be based on the average production during the two

- ye ar period prior to application to bubble. The facility 's annualPage 11 of 1 5 emissions may

not exceed the limit set by the emission baseline. Emissions must be reported monthly

and compliance with the emissio n 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 includ ed 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 SI P. 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 Recordkeep ing**  21.7.1 (a) The facility shall maintain the following information at the facility at all times. This information shall be kept current and be made available to the DEM or EPA upon request. 1. Printing coating press numberPage 12 of 1 5 2. Hours of operation per day or per y ear 3.
