R307-304-7. Add-on Emission Control Systems Operations

  (1) If an add-on control system is used, the owner or operator shall install and maintain the add-on control system in accordance with the manufacturer recommendations and maintain an overall capture and control efficiency of at least 85%. The overall capture and control efficiency shall be determined using EPA approved methods, as follows:

  (a) The capture efficiency of a VOC emission control system's VOC collection device 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.

  (b) 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.

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