Emission Limits for Affected Sources Using the Control Efficiency/Outlet Concentration Compliance Option

You must comply with the emission limits that apply to your affected source in the following table as required by § 63.3490(d). If you use the control efficiency/outlet concentration option to comply with the emission limitations for any coating operation(s) . . . Then you must comply with one of the following by using an emissions control system to . . . 1. in a new or reconstructed affected source a. reduce emissions of total HAP, measured as THC (as carbon), a by 97 percent; or b. limit emissions of total HAP, measured as THC (as carbon), a to 20 ppmvd at the control device outlet and use a PTE. 2. in an existing affected source a. reduce emissions of total HAP, measured as THC (as carbon), a by 95 percent; or b. limit emissions of total HAP, measured as THC (as carbon), a to 20 ppmvd at the control device outlet and use a PTE. a You may choose to subtract methane from THC as carbon measurements.
