Utah Admin. Code 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.
