OAR 340-232-0230: Rotogravure and Flexographic Printing

(1) No owner or operator of a packaging rotogravure, publication rotogravure, flexographic or specialty printing facility, with the potential to emit before add on controls greater than 100 tons/year, employing ink containing solvent may operate, cause, allow or permit the operation of the press unless: (a) The volatile fraction of ink, as it is applied to the substrate contains 25.0 percent by volume or less of organic solvent and 75 percent by volume or more of water; (b) The ink as it is applied to the substrate, less water, contains 60.0 percent by volume or more nonvolatile material; or (c) The owner or operator installs and operates: (A) A carbon absorption system which reduces the volatile organic emissions from the capture system by at least 90.0 percent by weight; (B) An incineration system which oxidizes at least 90.0 percent of the non methane VOCs, VOC measured as total combustible carbon, to carbon dioxide and water; or (C) An alternative VOC pollution control device demonstrated to have at least a 90.0 percent removal efficiency, measured across the air pollution control device, that has been approved by DEQ. (2) A capture system must be used in conjunction with the air pollution control devices in subsection (1)(c). The design and operation of a capture system must be consistent with good engineering practice, and must provide for a control efficiency in VOC emissions of at least: (a) 75.0 percent where a publication rotogravure process is employed; (b) 65.0 percent where a packaging rotogravure process is employed; or (c) 60.0 percent where a flexographic printing process is employed. (3) Compliance Demonstration: (a) Upon request of DEQ, the owner or operator of a VOC source must demonstrate compliance by the methods of this section or an alternative method approved by DEQ. All tests must be made by, or under the direction of, a person qualified by training and/or experience in the field of air pollution testing; (b) A person proposing to conduct a VOC emissions test must notify DEQ of the intent to test not less than 30 days before the proposed initiation of the tests so DEQ may observe the test. The notification must contain the information required by, and be in a format approved by, DEQ; (c) Test procedures to determine compliance with this rule must be approved by DEQ and consistent with: (A) EPA Test Method 18, 24, or 25, 40 CFR part 60; or California Method ST-7; or (B) DEQ may accept, instead of ink-solvent analysis, a certification by the ink manufacturer of the composition of the ink-solvent, if supported by actual batch formulation records. In the event of any inconsistency between an EPA Method test and a facility's formulation data, the EPA Method test will govern. (d) If an add-on control device is used, continuous monitors of the following parameters must be installed, periodically calibrated, and operated at all times that the associated control device is operating: (A) Exhaust gas temperature of all incinerators; (B) Breakthrough of VOC on a carbon adsorption unit; and (C) Temperature rise across a catalytic incinerator bed. [NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.] [NOTE: View a PDF of California Method by clicking on “Tables” link below.] [NOTE: View a PDF of referenced EPA Methods by clicking on “Tables” link below OAR 340-232-8010.]
