(a) You must be in compliance with the emission limitations in this subpart as specified in paragraphs (a)(1) and (2) of this section.
(1) Any coating operation(s) for which you use the compliant material option or the emission rate without add-on controls option, as specified in Sec. 63.3491(a) and (b), must be in compliance with the applicable emission limit in Sec. 63.3490.
(2) Any coating operation(s) for which you use the emission rate with add-on controls option, as specified in Sec. 63.3491(c), or the control efficiency/outlet concentration option, as specified in Sec. 63.3491(d), must be in compliance with the emission limitations as specified in paragraphs (a)(2)(i) through (iii) of this section.
(i) The coating operation(s) must be in compliance with the applicable emission limit in Sec. 63.3490 at all times.
(ii) The coating operation(s) must be in compliance with the operating limits for emission capture systems and add-on control devices required by Sec. 63.3492 at all times, except for those for which you use a solvent recovery system and conduct liquid-liquid material balances according to Sec. 63.3541(i). The operating limits apply only to capture systems and control devices used for purposes of complying with this subpart.
(iii) The coating operation(s) must be in compliance with the work practice standards in Sec. 63.3493 at all times.
(b) You must always operate and maintain your affected source, including all air pollution control and monitoring equipment you use for purposes of complying with this subpart, according to the provisions in Sec. 63.6(e)(1)(i).
(c) If your affected source uses an emission capture system and add-on control device for purposes of complying with this subpart, you must develop a written startup, shutdown, and malfunction plan (SSMP) according to the provisions in Sec. 63.6(e)(3). The plan must address startup, shutdown, and corrective actions in the event of a malfunction of the emission capture system or the add-on control device. The plan must also address any coating operation equipment that may cause increased emissions or that would affect capture efficiency if the process equipment malfunctions, such as conveyors that move parts among enclosures.
