Section 250-RICR-120-05-21.6 - ApplicabilityA. 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.c. A fifty percent (50%) volatile organic compounds retention factor shall be used for cleaning solution VOC in shop towels for cleaning solutions with a volatile organic compounds composite vapor pressure of no more than 10 mm of mercury (Hg) at 20°C (68°F) if the contaminated shop towels are kept in closed containers. This means fifty percent (50%) of the VOC used on the shop towels is emitted during the cleaning process.C. This regulation applies to any flexographic or rotogravure press at a flexible package printing facility whose combined actual emissions, before controls, during any consecutive 12-month period equal or exceed three (3) tons of VOC's.250 R.I.
