10. “Fountain solution reservoir” means the collection tank that accepts fountain solution recirculated from printing unit(s). In some cases, the tanks are equipped with cooling coils for refrigeration of the fountain solution.

11. “Heatset” means a lithographic printing process where the printing inks are set by the evaporation of ink oils in a heatset dryer.

12. “Heatset dryer” means any device used in heatset web offset lithographic printing to heat the printed substrate and to promote the evaporation of ink oils.

13. “Letterpress printing” means a printing process in which the image area is raised relative to the non-image area, and the paste ink is transferred to the substrate directly from the image surface;

14. “Lithographic printing” means a printing process in which the image and non-image areas are chemically differentiated, i.e., the image area is oil receptive and the non-image area is water receptive.

15. “Offset lithographic printing” means a printing process that transfers the ink film from the lithographic plate to an intermediary surface which is a rubber covered roller or blanket, which, in turn, transfers the ink film to the substrate.

A. This regulation applies to any roll, specialty, rotogravure, and flexographic printing facility whose potential to emit volatile organic compounds from printing operations is or ever has been, equal to or greater than fifty (50) tons/year.

B. This regulation applies to any offset lithographic and letterpress printing facility whose combined actual emissions, before controls, during any consecutive 12- month period equal or exceed three (3) tons of VOC's.

1. For determining applicability with § 21.6(B) of this Part the following retention factors should be used:

a. A twenty percent (20%) volatile organic compound retention factor shall be used for heatset inks, meaning eighty percent (80%) of the volatile organic compounds in the ink is emitted during the printing process.

b. A ninety-five percent (95%) volatile organic compounds retention factor shall be used for sheet-fed and non-heatset web inks printed on absorptive substrates, meaning five percent (5%) of the volatile organic compounds in the ink are emitted during the printing process.

4. 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 §§ 21.7.1(A)(1) or (2) of this Part. All alternative measures must be submitted for EPA approval as a source-specific SIP revision.

B. A capture system must be used in conjunction with the emission control devices installed per § 21.7.1(A)(3) of this Part. 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:

1. Seventy-five percent (75%) where publication rotogravure printing process is employed, or

2. Sixty-five percent (65%) where packaging rotogravure printing process or specialty printing process is employed, or

3. Sixty percent (60%) where flexographic printing process is employed.

C. Facilities using add-on controls to comply with § 21.7.1(A) of this Part must show that the equipment meets specific capture and control performance standards which will be set in an enforceable document.

D. 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, incorporated in § 21.4 of this Part, as follows:

Compliance Method

EPA Reference Test Method

Test Averaging Time

Reformulation

40 C.F.R. § 60 Appendix A-7 Method 24

Instantaneous

Solvent destruction or solvent recovery except carbon adsorption

40 C.F.R.§ 60 Appendix A-7 Method 25

3 hours

Carbon adsorption

40 C.F.R. § 60 Appendix A-7 Method 25 or other test method as appropriate

7 day rolling average

E. Other methods may be approved by the Director and EPA. Once the control efficiency has been determined for any add-on control device by 40 C.F.R. § 60 Appendix A-7 Method 25, incorporated in § 21.4 of this Part, or any alternative method approved by the Director 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.)

F. 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 (6) consecutive operating days to the total solvent usage for the same 7-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.

G. Control and capture equipment installed per §§ 21.7.1(A)(3) and 21.7.1(B) of this Part, will be incorporated in a permit issued in accordance with Part 9 of this Subchapter (Air Pollution Control Permits) 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.

Regulation Authority :

R.I. Gen. Laws § 42-17.1-2(19)
R.I. Gen. Laws Chapter 23-23
R.I. Gen. Laws Chapter 42-35

Purpose and Reason :

The purpose of this regulation is to limit emissions of volatile organic compounds from printing operations. The Department is proposing to amend Part 21 to meet the requirements contained in the EPA Control Technique Guideline Documents, “Control Techniques Guidelines for Offset Lithographic Printing and Letterpress Printing” and “Control Techniques Guidelines for Flexible Package Printing”. The amendments include new emissions limitations for offset lithographic, letterpress and flexible package printing and cleaning operations, recordkeeping requirements and work practice standards for offset lithographic, letterpress and flexible package printing facilities with emissions greater than three (3) tons in any twelve (12) month period

Additionally, definitions have been added and portions of the regulation that no longer apply have been eliminated. The regulation has been updated to current RI Code of Regulations (RICR) format which required the addition of an incorporated materials section.

Although R.I. Gen. Laws § 42-35-2.8, require that an oral hearing be granted if requested by twenty-five (25) persons, by an agency or by an association having at least twenty-five (25) members, an oral hearing will be granted if requested by one (1) or more persons during the public comment period.
