R307-351-6. Add-on Controls Systems Operations

  (1) If an add-on control system is used, the owner or operator shall install and maintain the add-on emission control system in accordance with the manufacturer recommendations.

  (a) Control devices for individual heatset web offset lithographic printing presses and individual heatset web letterpress printing press dryers that were installed prior to January 1, 2017, must maintain a 90% or greater control efficiency. Similar control devices installed after January 1, 2017, must maintain a 95% or greater control efficiency.

  (b) Control devices for individual flexographic printing presses and individual rotogravure printing presses shall comply with a 90% or greater overall control efficiency.

  (c) As an alternative to the control efficiency, the control device outlet concentration may be reduced to 20 ppmv as hexane on a dry basis to accommodate situations where the inlet VOC concentration is low or there is no identifiable measurable inlet. The control outlet concentration shall be determined using EPA Method 25A.

  (d) The capture efficiency of a VOC emission control system's VOC collection device for flexographic and rotogravure presses shall be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 CFR Part 51, Appendix M, Methods 204-204F, as applicable.

  (e) The capture efficiency of a VOC emission control system's VOC collection device for a heatset web offset press shall be determined by demonstrating that the airflow in the dryer is negative to the surrounding pressroom during the initial test using an air flow direction indicator, such as a smoke stick or aluminum ribbons, or differential pressure gauge.

  (f) The control efficiency of a VOC emission control system's VOC control device shall be determined using test methods in Appendices A-1, A-6, and A-7 to 40 CFR Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable.

  (g) An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator.
